本發明為一種影像處理技術，特別是指一種可以將多個影像拼接傳給預覽裝置之後再進行還原並進行靜態或動態影像預覽的一種影像預覽方法及預覽系統。The present invention is an image processing technology, in particular, an image preview method and a preview system that can splice multiple images and transmit them to a preview device, then restore and preview static or dynamic images.
請參閱圖1所示，該圖為習用之影像處理系統示意圖。影像處理系統1包括有影像處理裝置10、影像顯示裝置11以及影像預覽裝置12。影像處理裝置10具有複數個輸入介面100分別與複數個影像源13a~13c電性連接。影像源13a~13c可以為電腦、DVD 或藍光DVD播放裝置、或者是攝影裝置等，但不以此為限制。影像處理裝置10具有複數個第一輸出介面101分別與複數個顯示器110電性連接。本實施例中，複數個顯示器110拼接成電視牆作為影像顯示裝置11。影像處理裝置10更具有第二輸出介面102經由網路14與影像預覽裝置12電性連接。影像預覽裝置12可以為具有顯示器的電腦、智慧型手機或者是PAD電腦等。Please refer to Figure 1, which is a schematic diagram of a conventional image processing system. The image processing system 1 includes an image processing device 10 , an image display device 11 and an image preview device 12 . The image processing device 10 has a plurality of input interfaces 100 that are electrically connected to a plurality of image sources 13a to 13c respectively. The image sources 13a to 13c can be computers, DVD or Blu-ray DVD playback devices, or photography devices, but are not limited thereto. The image processing device 10 has a plurality of first output interfaces 101 that are electrically connected to a plurality of displays 110 respectively. In this embodiment, a plurality of displays 110 are spliced into a video wall as the image display device 11 . The image processing device 10 further has a second output interface 102 electrically connected to the image preview device 12 via the network 14 . The image preview device 12 may be a computer with a display, a smart phone, or a PAD computer.
習用技術中，影像預覽裝置12可以預覽與影像處理裝置10電性連接的該些影像源13a~13c所輸出的影像，以及也可以預覽與影像處理裝置10電性連接且拼接成電視牆的影像顯示裝置11的內容。雖然前述預覽的功能提供給使用者在遠端可以控制、設定以及預覽畫面的效果，但是在習用的預覽架構中，影像處理裝置10一次只針對單一輸入影像源13a~13c壓縮並傳送預覽畫面給影像預覽裝置12更新畫面，這樣更新預覽的方式存在更新預覽影像的效率問題。例如：如果影像處理裝置10連接有16台影像源，每一台影像源更新預覽畫面需要0.5秒，因此要完成一輪影像預覽更新需要經過8秒鐘，如此的更新速度也會造成預覽無法有效即時更新的問題。In conventional technology, the image preview device 12 can preview the images output by the image sources 13a to 13c that are electrically connected to the image processing device 10, and can also preview the images that are electrically connected to the image processing device 10 and spliced into a video wall. The contents of the display device 11 are displayed. Although the preview function mentioned above allows the user to control, set and preview the effect of the picture remotely, in the conventional preview architecture, the image processing device 10 only compresses and transmits the preview picture to a single input image source 13a~13c at a time. The image preview device 12 updates the screen. This way of updating the preview has an efficiency problem in updating the preview image. For example, if the image processing device 10 is connected to 16 image sources, it takes 0.5 seconds for each image source to update the preview screen. Therefore, it takes 8 seconds to complete a round of image preview updates. Such an update speed will also cause the preview to be ineffective and real-time. Updated question.
綜合上述，因此需要一種影像預覽方法及預覽系統，來解決習用技術所產生的問題。Based on the above, an image preview method and preview system are needed to solve the problems caused by conventional technologies.

However, the following embodiments are not intended to limit the present invention.
請參閱圖2與圖3所示，其中圖2為本發明之影像預覽方法之一實施例流程示意圖；圖3為本發明之預覽系統實施例架構示意圖。在本實施例中，圖2所示的影像預覽方法3，適用於圖3所示的預覽系統2中的影像處理裝置20以及影像預覽裝置22。影像處理裝置20具有複數個輸入介面200，例如：HDMI、DVI、D-Sub或者是USB介面等，但不以此為限制，以及輸出介面203。複數個輸入介面200分別電性連接多個影像來源裝置21a~21c，輸出介面203藉由網路通訊與影像預覽裝置22電性連接。影像來源裝置21a~21c可以為電腦、DVD或藍光DVD播放裝置、或者是攝影裝置，但不以此為限制。Please refer to FIGS. 2 and 3 . FIG. 2 is a schematic flow diagram of an embodiment of the image preview method of the present invention; FIG. 3 is a schematic structural diagram of a preview system according to an embodiment of the present invention. In this embodiment, FigureThe image preview method 3 shown in 2 is applicable to the image processing device 20 and the image preview device 22 in the preview system 2 shown in FIG. 3 . The image processing device 20 has a plurality of input interfaces 200 , such as HDMI, DVI, D-Sub or USB interfaces, but is not limited thereto, and an output interface 203 . The plurality of input interfaces 200 are electrically connected to a plurality of image source devices 21a to 21c respectively, and the output interface 203 is electrically connected to the image preview device 22 through network communication. The image source devices 21a to 21c can be computers, DVD or Blu-ray DVD playback devices, or photography devices, but are not limited thereto.
在圖2所示的預覽方法3之流程中，首先進行步驟30從該些影像來源裝置21a~21c中接收多個影像資料，本實施例中以第一影像資料VA以及第二影像資料VB來作說明。影像來源裝置20中包括有影像拼接模組201以及影像編碼與串流模組202，其中影像拼接模組201接收了多個影像資料，並對該些影像資料進行處理。步驟30之後進行步驟31，影像拼接模組201調整所接收之多個影像資料的解析度，讓多個影像資料可以藉由拼接成單個影像的方式從影像處理裝置20傳輸到影像預覽裝置22。在步驟31的一實施例中，以影像來源裝置21a~21b所輸出的第一影像資料VA與第二影像資料VB為例，在步驟31中影像拼接模組201利用縮放(scale)的功能調整了第一影像資料與第二影像資料的解析度，本實施例為縮小處理(downscale)以讓第一與第二影像資料VA與VB在經過縮放之後改變了解析度的大小，以形成第一與第二調整影像資料。本實施例中，第一調整影像資料與第二調整影像資料的解析度不相同，且第一調整影像資料的解析度大於第二調整影像資料的解析度，但本發明不以此為限。In the process of preview method 3 shown in Figure 2, step 30 is first performed to receive multiple image data from the image source devices 21a~21c. In this embodiment, the first image data VA and the second image data VB are used. Make an explanation. The image source device 20 includes an image splicing module 201 and an image encoding and streaming module 202. The image splicing module 201 receives a plurality of image data and processes the image data. After step 30, step 31 is performed. The image splicing module 201 adjusts the resolution of the multiple image data received so that the multiple image data can be transmitted from the image processing device 20 to the image preview device 22 by splicing them into a single image. In an embodiment of step 31, taking the first image data VA and the second image data VB output by the image source devices 21a~21b as an example, in step 31, the image splicing module 201 uses the scale function to adjust The resolution of the first image data and the second image data is determined. This embodiment performs a downscale process so that the resolution of the first and second image data VA and VB is changed after scaling to form the first image data VA and VB. and secondly adjust the image data. In this embodiment, the resolution of the first adjusted image data and the second adjusted image data are different, and the resolution of the first adjusted image data is greater than the resolution of the second adjusted image data, but the invention is not limited thereto.
接下來進行步驟32，將該些調整解析度後的第一與第二調整影像資料組成合一第一拼接影像資料。在影像拼接模組201中有拼接單元201a，用以儲存每一時間點拼接的影像。請參閱圖4A與圖4B所示，在圖4A中代表拼接單元201a儲存的空間，也代表傳輸頻寬，亦即單位時間能傳輸的資訊儲存量。在圖4B中，代表第一影像資料VA被縮小處理形成的第一調整影像資料IA以及第二影像資料VB被縮小處理後所形成的第二調整影像資料IB的資料被儲存在拼接單元201a內的儲存空間。圖4B中的斜線區域代表沒有被利用的儲存空間。在圖4B所示狀態對應的特定時間點下，儲存在拼接單元201a的第一與第二調整影像資料IA與IB構成了步驟32所示的第一拼接影像資料。要說明的是，圖4B所示的是以兩個影像來源裝置21a~21b所輸出的第一與第二影像資料VA與VB所形成的第一與第二調整影像拼接的結果。如果有多個的時候，例如圖4C所示的五個影像來源裝置輸出至影像拼接模組中，其所形成的第一拼接影像(IA~IE)佔滿了拼接單元201a的儲存空間，其中IC~IE代表其他影像來源裝置所輸出的影像資料經由解析度調整所形成的調整影像資料。Next, step 32 is performed to combine the first and second adjusted image data with adjusted resolutions into a first spliced image data. There is a splicing unit 201a in the image splicing module 201, which is used to store the spliced images at each time point. Please refer to Figure 4A and Figure 4B. Figure 4A represents the splicing unit.The storage space of 201a also represents the transmission bandwidth, that is, the amount of information storage that can be transmitted per unit time. In FIG. 4B, data representing the first adjusted image data IA formed by the reduction process of the first image data VA and the second adjusted image data IB formed by the reduction process of the second image data VB are stored in the splicing unit 201a. of storage space. The hatched area in Figure 4B represents unused storage space. At a specific time point corresponding to the state shown in FIG. 4B , the first and second adjusted image data IA and IB stored in the splicing unit 201 a constitute the first spliced image data shown in step 32 . It should be noted that what is shown in FIG. 4B is the result of splicing the first and second adjusted images formed by the first and second image data VA and VB output by the two image source devices 21a to 21b. If there are more than one, for example, the five image source devices shown in Figure 4C are output to the image stitching module, the first stitched images (IA~IE) formed by them occupy the storage space of the stitching unit 201a, where IC~IE represent adjusted image data formed by resolution adjustment of image data output by other image source devices.
再回到圖2所示，步驟32之後進行步驟33傳輸第一拼接影像資料給遠端的影像預覽裝置，影像預覽裝置將第一拼接影像資料還原。在本步驟中，如圖3所示，包含了兩個程序，首先影像處理裝置20內的影像編碼與串流模組202接收拼接單元201a中所儲存的第一拼接影像資料，然後將第一拼接影像編碼形成串流影像訊號ST經由網路23傳輸到影像預覽裝置22。如圖5所示，其係為串流影像訊號示意圖。串流影像訊號ST內包含有在每一個時間點T0~Tn時，影像編碼與串流模組202擷取影像拼接單元201a內相應的第一拼接影像(IA0+IB0)、(IA1+IB1)~(IAn+IBn)。串流影像訊號ST再經由網路23傳輸至遠端的影像預覽裝置22。如圖3所示，影像預覽裝置22收到了串流影像訊號ST之後，影像預覽裝置22內的影像解碼與串流模組220，將串流影像訊號ST解碼還原成第一拼接影像(IA0+IB0)、(IA1+IB1)~(IAn+IBn)。然後，影像切割模組221將第一拼接影像切割成對應多個影像來源裝置21a~21c所輸出的調整影像資料。以圖5所示的對應時間點T0的第一拼接影像(IA0+IB0)為例，經過影像切割模組221處理之後，會切割還原形成對應時間點T0時的第一調整影像資料IA0以及第二調整影像資料IB0。影像切割的技術為本領域技術之人所熟知，在此不作贅述。Returning to FIG. 2 , after step 32, step 33 is performed to transmit the first spliced image data to the remote image preview device, and the image preview device restores the first spliced image data. In this step, as shown in Figure 3, two procedures are included. First, the image encoding and streaming module 202 in the image processing device 20 receives the first spliced image data stored in the splicing unit 201a, and then converts the first spliced image data The spliced image coding forms a stream image signal ST which is transmitted to the image preview device 22 via the network 23 . As shown in Figure 5, it is a schematic diagram of a streaming video signal. The streaming image signal ST includes the corresponding first spliced images (IA0+IB0), (IA1+IB1) captured by the image encoding and streaming module 202 in the image splicing unit 201a at each time point T0~Tn. ~(IAn+IBn). The streaming image signal ST is then transmitted to the remote image preview device 22 via the network 23 . As shown in Figure 3, after the image preview device 22 receives the stream image signal ST, the image decoding and streaming module 220 in the image preview device 22 decodes the stream image signal ST and restores it to the first spliced image (IA0+ IB0), (IA1+IB1)~(IAn+IBn). Then, the image cutting module 221 cuts the first spliced image into corresponding adjusted image data output by the plurality of image source devices 21a to 21c. Taking the first spliced image (IA0+IB0) corresponding to the time point T0 shown in Figure 5 as an example, after being processed by the image cutting module 221, the first adjusted image data IA0 and the first adjusted image data IA0 and the first adjusted image data corresponding to the time point T0 will be cut and restored. 2. Adjust the image data IB0. The image cutting technology is well known to those skilled in the art and will not be described in detail here.
之後，進行步驟34，將還原後的調整影像資料透過影像預覽裝置於一第一時間進行預覽。本步驟中，承繼前述圖3與圖5所示之實施例，分割之後對應時間點T0的第一調整影像資料IA0與第二調整影像資料IB0分別在影像預覽裝置22的顯示器24上對應的預覽區域AR顯示出相應的影像。如圖3所示，顯示器24上的區域AR1與AR2於第一時間點顯示出對應時間點T0的第一調整影像資料IA0與第二調整影像資料IB0的影像畫面。同理，對應時間點T1的第一調整影像資料IA1與第二調整影像資料IB1的於第二時間點在影像畫面接續顯示，使得顯示區域AR1與AR2顯示出對應影像來源裝置所輸出的影像資料。要說明的是，IA0~IAn或IB0~IBn可以構成動態連續變化的影像，例如：以IA0~IAn為例，在時間點T0所還原的第一調整影像資料IA0與時間點T1所還原的第一影像資料IA1為不同幀的影像。在另一實施例中，IA0~IAn或IB0~IBn可以是為相同畫面的靜態影像，例如：以IA0~IAn為例，在時間點T0所還原的第一調整影像資料IA0與時間點T1所還原的第一影像資料IA1為相同的影像。After that, step 34 is performed to preview the restored adjusted image data at a first time through the image preview device. In this step, following the aforementioned embodiments shown in FIGS. 3 and 5 , the first adjusted image data IA0 and the second adjusted image data IB0 corresponding to the time point T0 after segmentation are previewed on the display 24 of the image preview device 22 respectively. Regional AR displays the corresponding image. As shown in FIG. 3 , the areas AR1 and AR2 on the display 24 display the image frames of the first adjusted image data IA0 and the second adjusted image data IB0 corresponding to the time point T0 at the first time point. Similarly, the first adjusted image data IA1 and the second adjusted image data IB1 corresponding to the time point T1 are continuously displayed on the image screen at the second time point, so that the display areas AR1 and AR2 display the image data output by the corresponding image source device. . It should be noted that IA0~IAn or IB0~IBn can constitute a dynamic and continuously changing image. For example, taking IA0~IAn as an example, the first adjusted image data IA0 restored at time point T0 and the first adjusted image data IA0 restored at time point T1 An image data IA1 is images of different frames. In another embodiment, IA0 ~ IAn or IB0 ~ IBn may be static images of the same frame. For example, taking IA0 ~ IAn as an example, the first adjusted image data IA0 restored at time point T0 and the first adjusted image data IA0 restored at time point T1 The restored first image data IA1 is the same image.
請參閱圖6所示，該圖為本發明影像預覽方法另一實施例示意圖。在圖6所示的影像預覽方法3a的流程中，基本上與圖2相似，差異的是，本實施例的步驟32a中根據要被拼接的各個調整影像資料所需要的頻寬大小進行步驟320判斷是否還有多餘的頻寬，如果有多餘的頻寬則會進行步驟321對至少一個影像資料的解析度重新進行縮放調整。例如，如圖7A與圖7B所示，該圖為形成第一拼接影像另一實施例示意圖。在本實施例中，主要針對如果頻寬還有剩餘的空間，本發明可以利用剩餘空間，進一步將影像解析度調高，讓傳輸頻寬可以充分被利用。圖7A中顯示出，對應四個影像來源裝置的經過縮小解析度處理之後所形成的第一至第四調整影像資料IA~ID，儲存在拼接單元201a內。在圖7A的斜線區域代表剩餘的儲存空間。如果沒有使用本實施例的步驟320，那麼剩餘的儲存空間沒有被利用，造成傳輸資源的浪費，也損失影像資料用比較高解析度來傳輸的機會。Please refer to FIG. 6 , which is a schematic diagram of another embodiment of the image preview method of the present invention. The process of the image preview method 3a shown in Figure 6 is basically similar to Figure 2. The difference is that in step 32a of this embodiment, step 320 is performed according to the bandwidth size required for each adjusted image data to be spliced. Determine whether there is excess bandwidth. If there is excess bandwidth, step 321 will be performed to rescale and adjust the resolution of at least one image data. For example, as shown in FIG. 7A and FIG. 7B , this figure is a schematic diagram of another embodiment of forming a first spliced image. In this embodiment, if there is remaining space in the bandwidth, the present invention can use the remaining space to further increase the image resolution so that the transmission bandwidth can be fully utilized. As shown in FIG. 7A , the first to fourth adjusted image data IA~ID formed after the resolution reduction process corresponding to the four image source devices are stored in the splicing unit 201a. The hatched area in Figure 7A represents the remaining storage space. If step 320 of this embodiment is not used, the remaining storage space is not used, resulting in a waste of transmission resources and a loss of the opportunity to transmit image data with a relatively high resolution.
因此，透過步驟320判斷還有剩餘的頻寬之後，再利用步驟321將來自於四個影像來源裝置的第一至第四影像資料的部分或全部進行縮放調整。要說明的是，要對哪一個影像來源裝置所輸出的影像資料進行縮放調整是根據使用者的需求而定，如圖7B所示，第三與第四影像資料被縮放調整解析度的比例與原先預定的縮放調整比例不同，因此經過縮放處理之後所形成的第三與第四調整影像資料IC與ID解析度增加，使得第一至第四調整影像資料IA~ID完全佔滿拼接單元201a的儲存空間，使得所有的第一至第四調整影像資料IA~ID充分利用頻寬。再回到圖6所示，之後進行步驟32a形成第一拼接影像資料，然後進行步驟33a傳輸至遠端的影像預覽裝置將第一影像拼接資料切割還原成獨立的各個第一至第四調整影像資料，最後進行步驟34a預覽顯示，前述步驟32a~34a的方式係如前所述，在此不作贅述。Therefore, after it is determined through step 320 that there is remaining bandwidth, step 321 is then used to perform scaling adjustment on part or all of the first to fourth image data from the four image source devices. It should be noted that which image source device outputs the image data to be scaled and adjusted depends on the user's needs. As shown in Figure 7B, the third and fourth image data are scaled and adjusted in a ratio of resolution The originally scheduled scaling adjustment ratios are different, so the resolution of the third and fourth adjusted image data IC and ID formed after the scaling process is increased, so that the first to fourth adjusted image data IA~ID completely occupy the space of the splicing unit 201a. The storage space enables all the first to fourth adjusted image data IA~ID to fully utilize the bandwidth. Returning to Figure 6, step 32a is then performed to form the first spliced image data, and then step 33a is performed to transmit the data to the remote image preview device to cut and restore the first image spliced data into independent first to fourth adjusted images. The data is finally previewed and displayed in step 34a. The methods of steps 32a to 34a are as described above and will not be described again here.
請參閱圖8所示，該圖為本發明之影像預覽方法另一實施例示意圖。在本實施例中的影像預覽方法3b，主要是針對在有限的頻寬之下，如何能夠保持高解析度的預覽畫面傳輸。本實施例的精神在於可以對不同影像來源裝置所輸出的影像資料進行權重設定，權重高的維持完整幀率(frame rate)的傳輸，權重低的則減低幀率(drop frame)。例如圖9A所示，假設有五個影像來源裝置提供的影像資料有部份或全部都需要有高的預覽解析度，當第一至第五影像資料經由解析度調整所形成的第一調整影像資料IA、第二調整影像資料IB以及第三調整影像資料IC、第四調整影像資料ID以及第五調整影像資料IE都要放到拼接單元201a內的話，會超過拼接單元201a有限的儲存容量。因此使用者可以透過設定權重高低的方式來進行傳輸，其中權重高的調整影像資料不減幀傳輸，而權重低的調整影像資料則以減幀的方式來傳輸，例如：第二調整影像資料IB以及第三調整影像資料IC的權重低，因此第二調整影像資料IB以及第三調整影像資料IC可以用減幀的方式，亦即不會每一個時間點都傳輸至影像預覽裝置，以達到傳輸的效果，如此就可以達到特定的影像資料可以在遠端的顯示器24以高解析度的方式進行預覽。Please refer to FIG. 8 , which is a schematic diagram of another embodiment of the image preview method of the present invention. The image preview method 3b in this embodiment is mainly aimed at how to maintain high-resolution preview image transmission under limited bandwidth. The spirit of this embodiment is that the weight of the image data output by different image source devices can be set. The one with a high weight maintains the transmission of the full frame rate (frame rate), and the one with a low weight reduces the frame rate (drop frame). For example, as shown in Figure 9A, assume that some or all of the image data provided by five image source devices require a high preview resolution. When the first to fifth image data are subjected to resolution adjustment, the first adjusted image is formed. If the data IA, the second adjusted image data IB, the third adjusted image data IC, the fourth adjusted image data ID and the fifth adjusted image data IE are all placed in the splicing unit 201a, the limited storage capacity of the splicing unit 201a will be exceeded. Therefore, the user can transmit by setting a high or low weight. The adjusted image data with a high weight is transmitted without frame reduction, while the adjusted image data with a low weight is transmitted with a frame reduction. For example: the second adjusted image data IB And the weight of the third adjusted image data IC is low, so the second adjusted image data IB and the third adjusted image data IC can use frame reduction, that is, they will not be transmitted to the image preview device at every time point to achieve transmission. The effect is achieved, so that specific image data can be previewed in a high-resolution manner on the remote display 24 .
在圖8的步驟30b中，影像處理裝置20於一時間點T0從該些影像來源裝置中接收第一影像資料、第二影像資料、第四至第五影像資料。然後進行步驟31b調整所接收之第一影像資料、第二影像資料、第四至第五影像資料的解析度，以形成第一調整影像資料IA0、第二調整影像資料IB0、第四至第五調整影像資料ID0與IE0，第一調整影像資料IA0之解析度大於第二調整影像資料IB0之解析度。然後以步驟32b將該些調整解析度後的各個調整影像資料IA0, IB0, ID0, IE0組成第一拼接影像資料。例如圖9C所示的對應在T0時間點時的第一調整影像資料IA0、第二調整影像資料IB0、第四調整影像資料ID0以及第五調整影像資料IE0所構成的第一拼接影像。然後以步驟33b傳輸第一拼接影像資料至遠端的影像預覽裝置，並將第一拼接影像資料還原。最後，再進行步驟34b將還原後的調整影像資料透過顯示器24預覽對應時間點T0的調整影像資料，例如圖9D所示的影像預覽裝置22的顯示器24上的畫面所呈現的預覽狀態。In step 30b of FIG. 8 , the image processing device 20 receives the first image data, the second image data, and the fourth to fifth image data from the image source devices at a time point T0. Then perform step 31b to adjust the resolution of the received first image data, second image data, and fourth to fifth image data to form first adjusted image data IA0, second adjusted image data IB0, fourth to fifth Adjusted image data ID0 and IE0, the resolution of the first adjusted image data IA0 is greater than the resolution of the second adjusted image data IB0. Then in step 32b, the adjusted image data IA0, IB0, ID0, IE0 after adjusting the resolution are combined into the first spliced image data. For example, the first spliced image shown in FIG. 9C is composed of the first adjusted image data IA0, the second adjusted image data IB0, the fourth adjusted image data ID0, and the fifth adjusted image data IE0 corresponding to the time point T0. Then in step 33b, the first spliced image data is transmitted to the remote image preview device, and the first spliced image data is restored. Finally, step 34b is performed to preview the adjusted image data corresponding to the time point T0 through the display 24 , such as the preview state shown on the display 24 of the image preview device 22 shown in FIG. 9D .
接著進行步驟35b，從該些影像來源裝置中接收時間點T1的第一影像資料、第三影像資料、第四至第五影像資料。然後以步驟36b調整第一影像資料、第三影像資料、第四至第五影像資料的解析度，以形成第一調整影像資料IA1、第三調整影像資料IC1、第四至第五調整影像資料ID1與IE1，第一調整影像資料IA1之解析度大於第三調整影像資料IC1之解析度。然後進行步驟37b，將該些調整解析度後的各個調整影像資料組成第二拼接影像資料。例如圖9E所示的對應時間點T1的第一調整影像資料IA1、第三調整影像資料IC1、第四調整影像資料ID1以及第五調整影像資料IE1所構成的拼接影像。然後以步驟38b傳輸第二拼接影像資料至遠端的影像預覽裝置，並將第二拼接影像資料還原，亦即將第二拼接影像切割成對應每一個影像來源裝置的調整影像資料。最後，再進行步驟39b將切割後的調整影像資料透過影像預覽裝置進行預覽，例如圖9F所示的影像預覽裝置22的顯示器24上的畫面所呈現的預覽狀態。Next, step 35b is performed to receive the first image data, the third image data, and the fourth to fifth image data at the time point T1 from the image source devices. Then step 36b is used to adjust the resolutions of the first image data, the third image data, and the fourth to fifth image data to form the first adjusted image data IA1, the third adjusted image data IC1, and the fourth to fifth adjusted image data. ID1 and IE1, the resolution of the first adjusted image data IA1 is greater than the resolution of the third adjusted image data IC1. Then step 37b is performed to combine the adjusted image data with adjusted resolutions into second spliced image data. For example, the spliced image composed of the first adjusted image data IA1, the third adjusted image data IC1, the fourth adjusted image data ID1, and the fifth adjusted image data IE1 corresponding to the time point T1 shown in FIG. 9E. Then in step 38b, the second spliced image data is transmitted to the remote image preview device, and the second spliced image data is restored, that is, the second spliced image is cut into adjusted image data corresponding to each image source device. Finally, step 39b is performed to preview the trimmed adjusted image data through the image preview device, such as the preview state shown on the display 24 of the image preview device 22 shown in FIG. 9F.
透過上述的流程，隨著時序的推移，可以看出第二調整影像資料IB0~n與第三調整影像資料IC0~n是交替式的更新。例如：時間點T2時(IB2, IC1), 時間點T3(IB2, IC3), 時間點T4(IB4, IC3)以此類推。透過第二調整影像資料IB0~n以及第三調整影像資料IC0~n減幀的方式，可以讓其他影像資料維持高解析度的方式進行預覽。要說明的是，使用者可以透過設定決定哪一些影像來源裝置所輸出的影像資料要減幀預覽，例如透過權重的設定，使得高權重的維持高解析度預覽，而低權重的則減幀預覽。Through the above process, as the time sequence goes by, it can be seen that the second adjustment image data IB0~n and the third adjustment image data IC0~n are updated alternately. For example: time point T2 (IB2, IC1), time point T3 (IB2, IC3), time point T4 (IB4, IC3) and so on. By reducing frames of the second adjusted image data IB0~n and the third adjusted image data IC0~n, other image data can be previewed while maintaining high resolution. It should be noted that the user can decide through settings which image data output by the image source device needs to be previewed with reduced frames. For example, through the setting of the weight, high-weighted ones maintain high-resolution previews, while those with low weights are previewed with reduced frames. .
請參閱圖10A，該圖為圖3所示之預覽系統實施例架構中的影像處理裝置實施例示意圖。在本實施例中，影像處理裝置20中的影像拼接模組201包括有複數個影像擷取單元201b分別與影像來源裝置21a~21c電性連接。影像擷取單元201b擷取影像來源裝置21a~21c所輸入的每一幀影像資料。被擷取的每一幀影像資料再輸入至縮放單元201c進行縮放處理。本實施例中，因為要將擷取的影像資料作為預覽的影像，因此縮放單元201c會將影像資料進行縮小解析度處理。縮小處理的目標解析度，是根據使用者的設定，並無一定之限制。要說明的是，縮放單元201c內更具有影像幀去除的功能，用來根據預覽影像解析度輸出的權重，執行前述如圖8所示的交替第二影像資料與第三影像資料的功能。Please refer to FIG. 10A , which is a schematic diagram of an embodiment of an image processing device in the architecture of the preview system embodiment shown in FIG. 3 . In this embodiment, the image stitching module 201 in the image processing device 20 includes a plurality of image capturing units 201b that are electrically connected to the image source devices 21a to 21c respectively. The image capturing unit 201b captures each frame of image data input by the image source devices 21a~21c. Each captured frame of image data is then input to the scaling unit 201c for scaling processing. In this embodiment, since the captured image data is used as a preview image, the scaling unit 201c reduces the resolution of the image data. The target resolution of the reduction process is based on the user's settings and there is no certain limit. It should be noted that the scaling unit 201c further has an image frame removal function, which is used to perform the aforementioned function of alternating the second image data and the third image data as shown in FIG. 8 according to the weight of the preview image resolution output.
縮放單元201c處理完畢之後的形成調整影像資料再經由先進先出的程序輸入至拼接單元201a。拼接單元201a接收來自於對應不同影像來源裝置21a~21c的調整影像資料，再將其拼接成拼接影像資料。要說明的是，拼接單元201a中具有儲存拼接影像的記憶體，其大小係配合影像處理裝置20傳輸給影像預覽裝置22的傳輸頻寬大小而定。因此每一時間點需要被預覽的影像來源裝置21a~21c的影像會被儲存在拼接單元201a內。在影像拼接模組201內更具有仲裁單元(arbiter)201d以及影像資訊產生單元201e。仲裁單元201d與拼接單元201a、影像擷取單元201b、縮放單元201c以及影像資訊產生單元201e電性連接。仲裁單元201d可以控制拼接單元201a、影像擷取單元201b、縮放單元201c以及影像資訊產生單元201e作動。影像資訊產生單元201e接收來自於仲裁單元201d關於拼接影像的資訊，例如：對應哪一個影像來源裝置、解析度，拼接位置與時間標記等資訊，並將該些資訊傳換成資訊訊號。The adjusted image data processed by the scaling unit 201c is then input to the splicing unit 201a through a first-in, first-out procedure. The splicing unit 201a receives adjusted image data from corresponding different image source devices 21a~21c, and then splices them into spliced image data. It should be noted that the splicing unit 201a has a memory for storing the spliced images, the size of which is determined by the transmission bandwidth of the image processing device 20 to the image preview device 22 . Therefore, the images of the image source devices 21a to 21c that need to be previewed at each time point will be stored in the splicing unit 201a. The image splicing module 201 further includes an arbitration unit (arbiter) 201d and an image information generating unit 201e. The arbitration unit 201d is electrically connected to the splicing unit 201a, the image capturing unit 201b, the scaling unit 201c and the image information generating unit 201e. The arbitration unit 201d can control the operations of the splicing unit 201a, the image capturing unit 201b, the scaling unit 201c, and the image information generating unit 201e. The image information generation unit 201e receives information about the spliced image from the arbitration unit 201d, such as the corresponding image source device, resolution, splicing position and time stamp, and transmits the information into an information signal.
每一時間點儲存在拼接單元201a的拼接影像再整個輸出至影像編碼與串流模組202的編碼單元202a，形成串流影像訊號ST輸出給多工器202b(MUX)。多工器202b也接收來自於影像資訊產生單元201e所輸出的關於每一拼接影像的資訊訊號，將資訊訊號疊加在串流影像訊號ST上。之後，串流影像訊號ST再經由網路單元202c輸出，經由網路傳至遠端的影像預覽裝置22。The spliced image stored in the splicing unit 201a at each time point is then completely output to the encoding unit 202a of the image encoding and streaming module 202, forming a streaming image signal ST that is output to the multiplexer 202b (MUX). The multiplexer 202b also receives the information signal about each spliced image output from the image information generation unit 201e, and superimposes the information signal on the stream image signal ST. Afterwards, the stream image signal ST is output through the network unit 202c and transmitted to the remote image preview device 22 through the network.
如圖10B所示，該圖為圖3所示之預覽系統實施例架構中的影像預覽裝置實施例示意圖。影像預覽裝置22接收串流影像訊號ST。本實施例中，影像預覽裝置22包括有影像解碼與串流模組220以及影像切割模組221。影像解碼與串流模組220內的網路單元220a接收串流影像訊號ST，然後解數據多工器(DMUX)220b將資訊訊號從串流影像訊號ST分離出來，再將串流影像訊號ST傳給解碼器220c還原成拼接影像資料之後，傳給影像切割模組221的分割單元221a。同時，資訊訊號傳給影像切割模組221的解析單元221b，其中，解析單元221b將關於拼接影像的資訊解出，例如：對應的影像來源裝置、解析度，拼接位置與時間標記等資訊等，並傳給分割單元221a。 然後分割單元221a再根據該些資訊，將拼接影像資料進行切割，以形成複數個對應不同影像來源裝置的調整影像資料，然後輸出個顯示器24進行預覽顯示。As shown in FIG. 10B , this figure is a schematic diagram of an embodiment of the image preview device in the architecture of the preview system embodiment shown in FIG. 3 . The image preview device 22 receives the streaming image signal ST. In this embodiment, the image preview device 22 includes an image decoding and streaming module 220 and an image cutting module 221. The network unit 220a in the image decoding and streaming module 220 receives the stream image signal ST, and then the data demultiplexer (DMUX) 220b separates the information signal from the stream image signal ST, and then separates the stream image signal ST After being passed to the decoder 220c to restore the spliced image data, it is passed to the segmentation unit 221a of the image cutting module 221. At the same time, the information signal is transmitted to the analysis unit 221b of the image cutting module 221, where the analysis unit 221b interprets information about the spliced image, such as the corresponding image source device, resolution, splicing position and time stamp, etc. and passed to the dividing unit 221a. Then the segmentation unit 221a cuts the spliced image data according to the information to form a plurality of adjusted image data corresponding to different image source devices, and then outputs the data to a monitor 24 for preview display.
綜合上述，本發明提供的影像預覽方法及預覽系統，可以將多個影像源的影像資料拼接成拼接影像資料，然後一起傳送至遠端的預覽裝置，預覽裝置收到拼接影像資料之後，進行分割還原的處理，將拼接影像資料還原成多個相應於該些影像源的影像資料，然後在預覽裝置的顯示畫面中顯示，以達到充分利用傳輸頻寬以及縮短預覽影像更新時間的效果。此外，本發明可以根據傳輸頻寬的資源，調整拼接影像中每一個預覽影像的解析度，例如：相比之下有的預覽影像的解析度大於其他預覽影像，並且根據使用者的需求調整不同影像源的幀率，達到充分利用頻寬傳輸的效果。Based on the above, the image preview method and preview system provided by the present invention can splice image data from multiple image sources into spliced image data, and then transmit them together to a remote preview device. After the preview device receives the spliced image data, it performs segmentation The restoration process restores the spliced image data into multiple image data corresponding to the image sources, and then displays them on the display screen of the preview device, so as to fully utilize the transmission bandwidth and shorten the preview image update time. In addition, the present invention can adjust the resolution of each preview image in the spliced image according to the transmission bandwidth resources. For example, in comparison, some preview images have a larger resolution than other preview images, and different adjustments can be made according to the user's needs. The frame rate of the image source achieves the effect of making full use of bandwidth transmission.
