光學成像的切換裝置、處理系統與方法Optical imaging switching device, processing system and method

關於一種光學成像的裝置、系統與方法，特別有關一種光學成像的切換裝置、處理系統與方法。A device, system and method for optical imaging, in particular a switching device, processing system and method for optical imaging.

隨著液晶顯示技術的快速發展，顯示設備的體積除了大幅的減縮外，還可以實現更大的顯示範圍。而更大的可視範圍可以提供使用者更加的沉浸感。通常而言，越大的顯示螢幕可以提供越大的可視範圍，例如電影螢幕或投影螢幕等。With the rapid development of liquid crystal display technology, the size of display devices has been greatly reduced, and a larger display range can be achieved. A larger viewing range can provide users with a greater sense of immersion. Generally speaking, a larger display screen can provide a larger viewing range, such as a movie screen or a projection screen.

對於一般使用者而言，由於受限於週邊環境或預算等限制，因此並不一定可以裝設大尺寸的螢幕或者投影機。雖然坊間有販售螢幕用的放大鏡。由於螢幕放大鏡僅提供畫面中的部分影像且平面的放大。對於螢幕中的影像的成像距離無實際變動且無法實現整個螢幕的放大，所以無法滿足使用者在視覺上的沉浸感的效果。For general users, it is not necessarily possible to install a large screen or projector due to restrictions such as the surrounding environment or budget. Although there are screen magnifiers for sale in the market. Since screen magnifiers only provide partial image magnification in the screen and flat magnification. There is no actual change in the imaging distance of the image on the screen and it is impossible to magnify the entire screen, so it cannot satisfy the user's visual immersion effect.

有鑑於此，在一些實施例中，所述的光學成像的切換裝置可以實現影像放大之外，也同時提供影像景深的感受，進而提升觀影者的沉浸感。In view of this, in some embodiments, the optical imaging switching device can achieve image magnification and also provide a sense of image depth, thereby enhancing the viewer's immersion.

The optical imaging switching device (hereinafter referred to as the imaging switching device 100) includes adisplay unit 110, abeam splitter 120, aconcave reflection unit 130 and afirst pivoting component 141.

顯示單元110具有第一顯示側邊111與第二顯示側邊112。顯示單元110可以是但不限定為液晶顯示器，也可以採用行動裝置的螢幕，或者其他種類的顯示器。顯示單元110運作時提供一顯示光源150。在圖2、圖3中為能表示顯示光源150的一側面，因此在顯示單元110的一側面以粗黑線段作為表示為顯示光源150的側面，並將此一側面稱為顯示面113。第一顯示側邊111與第二顯示側邊112為顯示面113的相對兩側邊。顯示單元110可以於原始位置(無標號)與投射位置(無標號)之間轉動，其轉動處理於後文另外說明。Thedisplay unit 110 has afirst display side 111 and asecond display side 112 . Thedisplay unit 110 may be, but is not limited to, a liquid crystal display, and may also be a screen of a mobile device, or other types of displays. Thedisplay unit 110 provides a displaylight source 150 during operation. In FIGS. 2 and 3 , the side of thedisplay light source 150 can be represented. Therefore, one side of thedisplay unit 110 is represented by a thick black line segment as the side of thedisplay light source 150 , and this side is called thedisplay surface 113 . Thefirst display side 111 and thesecond display side 112 are opposite sides of thedisplay surface 113 . Thedisplay unit 110 can rotate between the original position (no label) and the projection position (no label), and the rotation process will be described separately later.

分光片120具有第一分光側邊121、第二分光側邊122與分光鏡面123。第一分光側邊121與第二分光側邊122為相對兩側邊。分光鏡面123設置於第一分光側邊121與第二分光側邊122之間且面對凹面反射單元130的側面。在圖2的分光片120中係以粗黑線表示分光鏡面123。第一樞接部件141樞接第一顯示側邊111與第一分光側邊121。顯示面113的顯示範圍小於或等於分光鏡面123的範圍。Thebeam splitter 120 has a firstbeam splitting side 121, a secondbeam splitting side 122 and a beamsplitting mirror surface 123. The firstbeam splitting side 121 and the secondbeam splitting side 122 are opposite sides. The beamsplitting mirror surface 123 is disposed between the firstbeam splitting side 121 and the secondbeam splitting side 122 and faces the side of theconcave reflection unit 130. In thebeam splitter 120 of FIG. 2, the beamsplitting mirror surface 123 is indicated by a thick black line. Thefirst hinge component 141 hinges thefirst display side 111 and the firstbeam splitting side 121. The display range of thedisplay surface 113 is less than or equal to the range of the beamsplitting mirror surface 123.

顯示單元110的第一顯示側邊111以第一樞接部件141為軸心轉動，顯示單元110的第二顯示側邊112可以在原始位置與投射位置之間轉動。為方便說明，成像切換裝置100於展開或折疊時顯示單元110的擺放狀態，因此將以顯示單元110位於原始位置或投射位置作為代稱。原始位置為成像切換裝置100折疊後顯示單元110位於分光片120的前方，如圖3所示。相對的，投射位置為成像切換裝置100展開後顯示單元110位於分光片120上方。顯示單元110於投射位置時，第二分光側邊122可以抵靠於凹面反射單元130。Thefirst display side 111 of thedisplay unit 110 rotates around thefirst hinge part 141, and thesecond display side 112 of thedisplay unit 110 can rotate between the original position and the projection position. For the convenience of explanation, thedisplay unit 110 is placed when theimaging switching device 100 is unfolded or folded, so thedisplay unit 110 is located in the original position or the projection position as a synonym. The original position is that thedisplay unit 110 is located in front of thebeam splitter 120 after theimaging switching device 100 is folded, as shown in Figure 3. In contrast, the projection position is that thedisplay unit 110 is located above thebeam splitter 120 after theimaging switching device 100 is unfolded. When thedisplay unit 110 is in the projection position, the secondbeam splitter side 122 can be against theconcave reflection unit 130.

當顯示單元110位於原始位置，顯示面113的顯示光源150不會投射至分光鏡面123，如圖3所示。當顯示單元110位於投射位置時，顯示單元110將顯示光源150投射至分光鏡面123。分光鏡面123將部分反射的顯示光源150的光線至凹面反射單元130，此一光線稱為第一光線151a。圖4的黑色垂直箭頭線段係為顯示光源150的光線，圖4的黑色水平箭頭線段係為第一光線151a，垂直虛線線段為透射過分光片120的光線。When thedisplay unit 110 is at the original position, thedisplay light source 150 of thedisplay surface 113 will not be projected onto thedichroic mirror surface 123, as shown in FIG3. When thedisplay unit 110 is at the projection position, thedisplay unit 110 projects thedisplay light source 150 onto thedichroic mirror surface 123. Thedichroic mirror surface 123 partially reflects the light of thedisplay light source 150 to theconcave reflection unit 130, and this light is called thefirst light 151a. The black vertical arrow line segment in FIG4 is the light of thedisplay light source 150, the black horizontal arrow line segment in FIG4 is thefirst light 151a, and the vertical dotted line segment is the light transmitted through thedichroic plate 120.

凹面反射單元130具有第一單元側邊131、第二單元側邊132與凹反射面133，第一單元側邊131與第二單元側邊132為相對兩側邊。凹反射面133設置於第一單元側邊131與第二單元側邊132之間。凹反射面133將第一光線151a反射至分光片120。當顯示單元110位於原始位置，凹反射面133正對於分光片120的分光鏡面123。凹面反射單元130、分光片120與顯示單元110三者相互平行，如圖3所示。Theconcave reflection unit 130 has afirst unit side 131, asecond unit side 132 and aconcave reflection surface 133, and thefirst unit side 131 and thesecond unit side 132 are opposite sides. Theconcave reflection surface 133 is arranged between thefirst unit side 131 and thesecond unit side 132. Theconcave reflection surface 133 reflects thefirst light 151a to thebeam splitter 120. When thedisplay unit 110 is in the original position, theconcave reflection surface 133 is opposite to thebeam splitter surface 123 of thebeam splitter 120. Theconcave reflection unit 130, thebeam splitter 120 and thedisplay unit 110 are parallel to each other, as shown in FIG3.

在一些實施例中，凹反射面133的光軸與分光鏡面123的夾角為45度。分光片120的透射率與反射率是取決於鍍膜材質。在此為方便說明，在圖2、圖4、圖5中均以45度角作為分光片120的透射與反射的說明。顯示單元110與分光片120的夾角係為45度，且第二光線151b與分光片120的夾角也為45度。In some embodiments, the angle between the optical axis of the concavereflective surface 133 and thebeam splitter surface 123 is 45 degrees. The transmittance and reflectance of thebeam splitter 120 depend on the coating material. For the convenience of explanation, the transmission and reflection of thebeam splitter 120 are illustrated at an angle of 45 degrees in Figures 2, 4, and 5. The angle between thedisplay unit 110 and thebeam splitter 120 is 45 degrees, and the angle between thesecond light 151b and thebeam splitter 120 is also 45 degrees.

當顯示單元110位於投射位置時，第二顯示側邊112位於凹面反射單元130的第一單元側邊131。第二顯示側邊112可以通過卡扣、磁力或其他固定結構被固定於第一單元側邊131。凹面反射單元130可以將第一光線151a反射至分光鏡面123，而凹面反射單元130反射至分光鏡面123的光線稱其為第二光線151b，請參考圖4中的黑色水平箭頭線段。凹面反射單元130用以放大顯示單元110的虛像成像範圍，而所形成的虛像後文均稱為虛擬圖像212。凹面反射單元130的放大倍率根據凹面曲率所決定。凹面反射單元130右側的虛線線段為虛像的成像像距，稱其為虛像像距211。When thedisplay unit 110 is at the projection position, thesecond display side 112 is located at thefirst unit side 131 of the concavereflective unit 130. Thesecond display side 112 can be fixed to thefirst unit side 131 by a buckle, a magnetic force or other fixing structure. The concavereflective unit 130 can reflect thefirst light 151a to thespectroscopic mirror surface 123, and the light reflected by the concavereflective unit 130 to thespectroscopic mirror surface 123 is called thesecond light 151b, please refer to the black horizontal arrow line segment in FIG. 4. The concavereflective unit 130 is used to enlarge the virtual image imaging range of thedisplay unit 110, and the virtual image formed is hereinafter referred to as avirtual image 212. The magnification of the concavereflective unit 130 is determined according to the concave curvature. The dashed line segment on the right side of the concavereflective unit 130 is the imaging distance of the virtual image, which is called thevirtual image distance 211.

第二光線151b反射至分光鏡面123時，將會有部分的第二光線151b透射過分光鏡面123，而透射出的光線後稱為第三光線151c。使用者T可以通過分光片120與凹面反射單元130觀看第三光線151c與其相應的虛擬圖像212。而顯示光源150、第一光線151a、第二光線151b與第三光線151c所形成的光路集合即為第一光路151，請參考圖2所示。When thesecond light 151b is reflected to thespectroscopic mirror surface 123, part of thesecond light 151b will be transmitted through thespectroscopic mirror surface 123, and the transmitted light is called thethird light 151c. The user T can view thethird light 151c and its correspondingvirtual image 212 through thespectroscopic plate 120 and theconcave reflection unit 130. The light path set formed by thedisplay light source 150, thefirst light 151a, thesecond light 151b and thethird light 151c is the firstlight path 151, please refer to Figure 2.

顯示單元110位於投射位置，顯示單元110至使用者T之間的光路即為第一光路151。使用者T透過分光片120與凹面反射單元130可以觀看顯示單元110的放大後的虛擬圖像212。並且通過凹面反射單元130的反射後，虛擬圖像212也會呈現彎曲的視覺效果，請參考圖1所示。當顯示單元110位於原始位置時，顯示單元110的顯示光源150直接投射至使用者T，而此一光路為第二光路152。Thedisplay unit 110 is located at the projection position, and the optical path from thedisplay unit 110 to the user T is the firstoptical path 151. The user T can view the enlargedvirtual image 212 of thedisplay unit 110 through thebeam splitter 120 and the concavereflective unit 130. And after being reflected by the concavereflective unit 130, thevirtual image 212 will also present a curved visual effect, as shown in FIG1. When thedisplay unit 110 is located at the original position, thedisplay light source 150 of thedisplay unit 110 is directly projected to the user T, and this optical path is the secondoptical path 152.

在一些實施例中，成像切換裝置100更具有第二樞接部件142，請參考圖6。第二樞接部件142樞接於第二分光側邊122與第二單元側邊132。分光片120以第二樞接部件142為軸心轉動，使得第一分光側邊121可以移離或移近第一單元側邊131。當顯示單元110轉動至投射位置時，第一分光側邊121移離第一單元側邊131，並且第一單元側邊131抵住第一顯示側邊111，如圖6中的下方所示。第一單元側邊131可以通過扣合、磁性定位或者套接等方式藉以固定於第一單元側邊131。於此同時，顯示單元110、分光片120與凹面反射單元130之間形成一投射空間(無標號)，以供第一光線151a、第二光線151b的反射。In some embodiments, theimaging switching device 100 further has asecond hinge component 142, see FIG6 . Thesecond hinge component 142 is hinged to the secondbeam splitting side 122 and thesecond unit side 132. Thebeam splitter 120 rotates around thesecond hinge component 142, so that the firstbeam splitting side 121 can move away from or move closer to thefirst unit side 131. When thedisplay unit 110 rotates to the projection position, the firstbeam splitting side 121 moves away from thefirst unit side 131, and thefirst unit side 131 abuts against thefirst display side 111, as shown in the lower part of FIG6 . Thefirst unit side 131 can be fixed to thefirst unit side 131 by snapping, magnetic positioning or sleeve connection. At the same time, a projection space (no number) is formed between thedisplay unit 110, thebeam splitter 120 and theconcave reflection unit 130 for reflection of thefirst light 151a and thesecond light 151b.

在一些實施例中，成像切換裝置100更具有卡扣結構143，如圖7A與圖7B所示。卡扣結構143具有兩第一固定臂143a、兩第二固定臂143b、兩第一延展臂143c與兩第二延展臂143d。在圖7A中係為卡扣結構的右側視圖。兩第一固定臂143a分別固定設置於分光片120的相對兩側邊。兩第二固定臂143b分別固定設置於凹面反射單元130的相對兩側邊。第一固定臂143a的一端樞接於第二固定臂143b的一端。第一延展臂143c的一端樞接於第一固定臂143a之中，第一延展臂143c的另一端樞接於第二延展臂143d的一端。第二延展臂143d的另一端樞接於第二固定臂143b的另一端。In some embodiments, theimaging switching device 100 further has a snap-fit structure 143, as shown in FIG. 7A and FIG. 7B. The snap-fit structure 143 has two firstfixed arms 143a, two secondfixed arms 143b, twofirst extension arms 143c and twosecond extension arms 143d. FIG. 7A is a right side view of the snap-fit structure. The two firstfixed arms 143a are fixedly disposed on opposite sides of thebeam splitter 120. The two secondfixed arms 143b are fixedly disposed on opposite sides of theconcave reflection unit 130. One end of the firstfixed arm 143a is pivoted to one end of the secondfixed arm 143b. One end of thefirst extension arm 143c is pivoted to the firstfixed arm 143a, and the other end of thefirst extension arm 143c is pivoted to one end of thesecond extension arm 143d. The other end of thesecond extension arm 143d is hinged to the other end of the secondfixed arm 143b.

當顯示單元110位於原始位置，第一延展臂143c與第二延展臂143d樞轉並收合，使得分光片120可以抵靠住凹面反射單元130，如圖7A所示。當顯示單元110位於投射位置，第一延展臂143c與第二延展臂143d的兩端分別樞轉並延伸展開，使得分光片120移離凹面反射單元130，如圖7B所示。When thedisplay unit 110 is in the original position, thefirst extension arm 143c and thesecond extension arm 143d pivot and retract, so that thebeam splitter 120 can abut against theconcave reflection unit 130, as shown in FIG7A. When thedisplay unit 110 is in the projection position, the two ends of thefirst extension arm 143c and thesecond extension arm 143d pivot and extend, respectively, so that thebeam splitter 120 moves away from theconcave reflection unit 130, as shown in FIG7B.

在一些實施例中，成像切換裝置100更具有可撓性連接部件144，如圖7C所示。可撓性連接部件144連接於第二分光側邊122與第二單元側邊132。當第二分光側邊122為軸心的轉動時，可撓性連接部件144提供分光片120與凹面反射單元130的連接，以供第一分光側邊121可以移離或移近第一單元側邊131。可撓性連接部件144可以是但不限定為軟性電路板，也可以是魔鬼沾、橡膠或彈性布料等。In some embodiments, theimaging switching device 100 further has a flexible connectingcomponent 144, as shown in FIG. 7C. The flexible connectingcomponent 144 is connected to the secondlight splitting side 122 and thesecond unit side 132 . When the secondlight splitting side 122 rotates about the axis, the flexible connectingcomponent 144 provides a connection between thelight splitting plate 120 and theconcave reflection unit 130 so that the firstlight splitting side 121 can move away from or move closer to the first unit side.Side 131. The flexible connectingcomponent 144 may be, but is not limited to, a flexible circuit board, and may also be Velcro, rubber or elastic cloth.

在一些實施例中，切換光學成像的處理系統(簡稱為處理系統800)包括成像切換裝置100、顯示單元110與處理單元810，請參考圖8、圖9。處理單元810電性連接於顯示單元110與成像切換裝置100。顯示單元110提供顯示光源150至使用者T或成像切換裝置100，並形成第一光路151或第二光路152。顯示單元110的第一光路151與第二光路152可以參考前文所述。In some embodiments, the processing system for switching optical imaging (referred to as processing system 800) includes animaging switching device 100, adisplay unit 110 and aprocessing unit 810, see Figures 8 and 9. Theprocessing unit 810 is electrically connected to thedisplay unit 110 and theimaging switching device 100. Thedisplay unit 110 provides a displaylight source 150 to the user T or theimaging switching device 100, and forms a firstoptical path 151 or a secondoptical path 152. The firstoptical path 151 and the secondoptical path 152 of thedisplay unit 110 can refer to the above description.

成像切換裝置100具有分光片120、凹面反射單元130、第一樞接部件141與感測單元161。凹面反射單元130、分光片120與第一樞接部件141的連接方式與作動可以參考前一實施態樣的說明。感測單元161配置於凹面反射單元130的第一單元側邊131。感測單元161用以偵測顯示單元110是否位於投射位置。當顯示單元110位於投射位置，顯示單元110靠抵並觸發感測單元161，使感測單元161產生投射訊號911。感測單元161傳送投射訊號911至處理單元810。感測單元161可以是按壓開關、磁簧開關或光敏電阻等方式實現。圖9中係以按壓開關為感測單元161為例，當顯示單元110抵靠於第一單元側邊121時，顯示單元110將會觸壓感測單元161，直至顯示單元110由投射位置轉至原始位置。Theimaging switching device 100 has abeam splitter 120, aconcave reflection unit 130, afirst pivot component 141 and asensing unit 161. The connection method and operation of theconcave reflection unit 130, thebeam splitter 120 and thefirst pivot component 141 can refer to the description of the previous embodiment. Thesensing unit 161 is configured on thefirst unit side 131 of theconcave reflection unit 130. Thesensing unit 161 is used to detect whether thedisplay unit 110 is located at the projection position. When thedisplay unit 110 is located at the projection position, thedisplay unit 110 abuts against and triggers thesensing unit 161, so that thesensing unit 161 generates a projection signal 911. Thesensing unit 161 transmits the projection signal 911 to theprocessing unit 810. Thesensing unit 161 can be implemented by a push switch, a reed switch, or a photoresistor. FIG9 takes the push switch as thesensing unit 161 as an example. When thedisplay unit 110 is against thefirst unit side 121, thedisplay unit 110 will press thesensing unit 161 until thedisplay unit 110 is turned from the projection position to the original position.

處理單元810電性連接於顯示單元110與感測單元161。處理單元810根據投射訊號911輸出影像調整訊號820，並將影像輸出調整訊號發送至顯示單元110。顯示單元110根據影像調整訊號820調整自身的影像參數，藉以調整顯示單元110的播放影像的內容。Theprocessing unit 810 is electrically connected to thedisplay unit 110 and thesensing unit 161. Theprocessing unit 810 outputs animage adjustment signal 820 according to the projection signal 911, and sends the image output adjustment signal to thedisplay unit 110. Thedisplay unit 110 adjusts its own image parameters according to theimage adjustment signal 820, thereby adjusting the content of the image played by thedisplay unit 110.

為進一步說明處理系統800的整體運作，請配合參考圖10，其係為在一些實施例的處理系統之運作流程示意圖。To further illustrate the overall operation of theprocessing system 800, please refer to FIG. 10 , which is a schematic diagram of the operation flow of the processing system in some embodiments.

步驟S910：由處理單元偵測顯示單元位於成像切換裝置的原始位置或投射位置，其中顯示單元的第一顯示側邊樞接於成像切換裝置，顯示單元以第一顯示側邊為軸心在原始位置與投射位置之間轉動；步驟S920：顯示單元位於原始位置，顯示單元投射顯示光源至使用者，用以形成第二光路；步驟S930：顯示單元由原始位置轉往至投射位置，處理單元調整顯示單元的影像參數；以及步驟S940：當顯示單元位於投射位置，顯示單元的顯示光源投射至成像切換裝置，於成像切換裝置的投射空間中形成第一光路。Step S910: The processing unit detects that the display unit is located at the original position or the projection position of the imaging switching device, wherein the first display side of the display unit is hinged to the imaging switching device, and the display unit rotates between the original position and the projection position with the first display side as the axis; Step S920: The display unit is located at the original position, and the display unit projects a display light source to the user to form a second light path; Step S930: The display unit rotates from the original position to the projection position, and the processing unit adjusts the image parameters of the display unit; and Step S940: When the display unit is located at the projection position, the display light source of the display unit is projected to the imaging switching device to form a first light path in the projection space of the imaging switching device.

首先，成像切換裝置100處於折疊的狀態，意即為顯示單元110位於原始位置。使用者T可以致能顯示單元110運作，並且顯示單元110將顯示光源150直接投射至使用者T並形成第二光路152，請參考圖3所示。將顯示單元110從原始位置轉動至投射位置，如圖2所示。當顯示單元110位於投射位置時投射顯示光源150，顯示單元110、分光片120與凹面反射單元130之間形成一個投射空間。顯示單元110投射顯示光源150至分光片120與凹面反射單元130。First, theimaging switching device 100 is in a folded state, which means that thedisplay unit 110 is in the original position. The user T can enable thedisplay unit 110 to operate, and thedisplay unit 110 projects thedisplay light source 150 directly to the user T and forms a secondlight path 152, as shown in FIG3. Thedisplay unit 110 is rotated from the original position to the projection position, as shown in FIG2. When thedisplay unit 110 is in the projection position, thedisplay light source 150 is projected, and a projection space is formed between thedisplay unit 110, thebeam splitter 120 and theconcave reflection unit 130. Thedisplay unit 110 projects thedisplay light source 150 to thebeam splitter 120 and theconcave reflection unit 130.

在一些實施例中，成像切換裝置100更具有第二樞接部件142。第二樞接部件142連接於第二分光側邊122與第二單元側邊132。當顯示單元110從原始位置轉動至投射位置時，分光片120也會以第二樞接部件142為軸心轉動，使得分光片120移離凹面反射單元130。此外，成像切換裝置100也可以以可撓性連接部件144分別連接第二分光側邊122與第二單元側邊132。In some embodiments, theimaging switching device 100 further has asecond pivoting component 142. Thesecond pivoting component 142 is connected to the secondbeam splitting side 122 and thesecond unit side 132. When thedisplay unit 110 rotates from the original position to the projection position, thebeam splitter 120 also rotates around thesecond pivoting component 142, so that thebeam splitter 120 moves away from theconcave reflection unit 130. In addition, theimaging switching device 100 can also be connected to the secondbeam splitting side 122 and thesecond unit side 132 respectively with a flexible connectingcomponent 144.

在一些實施例中，感測單元161可以設置於凹面反射單元130的第二單元側邊132(無繪示感測單元161)。當顯示單元110位於原始位置時，感測單元161將接觸於分光片120。當顯示單元110轉動至投射位置時，感測單元161可以被釋放並產生投射訊號911。反之，當顯示單元110由投射位置轉向至原始位置時，感測單元161輸出回復訊號912至處理單元810，使顯示單元110的亮度從投射亮度調整為初始亮度。In some embodiments, thesensing unit 161 can be disposed on thesecond unit side 132 of the concave reflective unit 130 (thesensing unit 161 is not shown). When thedisplay unit 110 is at the original position, thesensing unit 161 will contact thebeam splitter 120. When thedisplay unit 110 rotates to the projection position, thesensing unit 161 can be released and generate a projection signal 911. Conversely, when thedisplay unit 110 rotates from the projection position to the original position, thesensing unit 161 outputs a feedback signal 912 to theprocessing unit 810, so that the brightness of thedisplay unit 110 is adjusted from the projection brightness to the initial brightness.

而影像參數包括顯示區域、顯示比例、區域亮度、影像對比度、影像銳利度或反轉影像。顯示區域意即為顯示單元110的可視範圍，請參考圖11A與圖11B所示。圖11A係為顯示單元110位於原始位置，圖11B係為顯示單元110位於投射位置。顯示單元110中的虛線框為顯示區域，可以將顯示區域視為顯示面113。The image parameters include display area, display ratio, area brightness, image contrast, image sharpness or inverted image. The display area means the visible range of thedisplay unit 110, please refer to Figures 11A and 11B. Figure 11A shows thedisplay unit 110 in the original position, and Figure 11B shows thedisplay unit 110 in the projection position. The dotted frame in thedisplay unit 110 is the display area, and the display area can be regarded as thedisplay surface 113.

當顯示單元110位於投射位置，第一單元側邊131遮蔽顯示區域的底部，如圖11B所示。因此處理單元810可以發送將可視範圍縮小的影像調整訊號820，使顯示單元110的可視範圍縮放至相應範圍。處理單元810可以根據凹面反射單元130的曲率調整顯示單元110的顯示區域的顯示比例。When thedisplay unit 110 is in the projection position, thefirst unit side 131 covers the bottom of the display area, as shown in FIG. 11B. Therefore, theprocessing unit 810 can send animage adjustment signal 820 to reduce the visible range, so that the visible range of thedisplay unit 110 is scaled to a corresponding range. Theprocessing unit 810 can adjust the display ratio of the display area of thedisplay unit 110 according to the curvature of theconcave reflection unit 130.

除了顯示區域的調整外，由於人眼的雙眼可視視角的範圍大約為124度。所以會將放大後的虛擬圖像212需要是位於人眼的可視視角的範圍之中。對於凹面成像而言，物距與放大倍率係為反比。若以16：9的32吋的顯示單元110為例，顯示單元110的寬約為76cm、高約為45cm。分光片120至凹面反射單元130之間的物距約為22.5cm~30cm(其區間係為凹反射面133的曲率所決定)。而於此範圍的虛擬圖像212與使用者T的像距約為1m，並且虛擬圖像212的範圍也接近可視視角的最大值。但並不侷限於前述尺寸的顯示單元110，所述的實施態樣也可以應用在其他尺寸的顯示單元110中。In addition to the adjustment of the display area, since the human eye's binocular viewing angle range is approximately 124 degrees. Therefore, the enlargedvirtual image 212 needs to be within the range of the human eye's viewing angle. For concave imaging, the object distance is inversely proportional to the magnification. Taking a 16:9 32-inch display unit 110 as an example, thedisplay unit 110 is approximately 76 cm wide and 45 cm high. The object distance between thebeam splitter 120 and theconcave reflection unit 130 is approximately 22.5 cm~30 cm (the range is determined by the curvature of the concave reflection surface 133). The image distance between thevirtual image 212 and the user T in this range is approximately 1 m, and the range of thevirtual image 212 is also close to the maximum value of the viewing angle. However, it is not limited to thedisplay unit 110 of the aforementioned size, and the implementation described can also be applied to displayunits 110 of other sizes.

處理單元810根據分光片120的透射/反射亮度衰減的比例向顯示單元110發送調高亮度的影像調整訊號820。在此將顯示光源150的原始亮度稱為初始亮度，而調整後的顯示光源150的亮度為投射亮度。若分光片120的透射/反射後的亮度為50%。由於顯示光源150經過兩次反射與一次透射，分別是第一次反射為分光片120、第二次由凹面反射單元130反射、一次透射為分光片120。分光片120反射後使得顯示光源150的亮度下降50%，而凹面反射單元130反射第一光線151a不造成亮度下降，所以第三光線151c的亮度為顯示光源150的亮度25%。因此，處理單元810可以驅動顯示單元110將顯示光源150的亮度調整為400%，以使第三光線151c的亮度與原始位置的顯示光源150的亮度一致。換言之，顯示單元110轉動至於投射位置，處理單元810將顯示單元110的初始亮度調整為投影亮度，而投影亮度大於初始亮度。在一實施例中，處理單元810也可以同時調整影像對比度、銳利度，藉以凸顯虛擬圖像212的成像。Theprocessing unit 810 sends animage adjustment signal 820 to thedisplay unit 110 to increase the brightness according to the ratio of the attenuation of the transmission/reflection brightness of thebeam splitter 120. Here, the original brightness of thedisplay light source 150 is referred to as the initial brightness, and the brightness of thedisplay light source 150 after adjustment is the projection brightness. If the brightness after transmission/reflection of thebeam splitter 120 is 50%. Since thedisplay light source 150 is reflected twice and transmitted once, the first reflection is thebeam splitter 120, the second reflection is reflected by theconcave reflection unit 130, and the first transmission is thebeam splitter 120. After the reflection of thebeam splitter 120, the brightness of thedisplay light source 150 decreases by 50%, and the reflection of thefirst light ray 151a by theconcave reflection unit 130 does not cause a decrease in brightness, so the brightness of the thirdlight ray 151c is 25% of the brightness of thedisplay light source 150. Therefore, theprocessing unit 810 can drive thedisplay unit 110 to adjust the brightness of thedisplay light source 150 to 400% so that the brightness of thethird light 151c is consistent with the brightness of thedisplay light source 150 at the original position. In other words, when thedisplay unit 110 rotates to the projection position, theprocessing unit 810 adjusts the initial brightness of thedisplay unit 110 to the projection brightness, and the projection brightness is greater than the initial brightness. In one embodiment, theprocessing unit 810 can also adjust the image contrast and sharpness at the same time to highlight the imaging of thevirtual image 212.

The components and connection methods of thedisplay unit 110, theimaging switching device 100, and theprocessing unit 810 can refer to the aforementioned embodiments. Thecomputer 840 is electrically connected to thedisplay unit 110 and theprocessing unit 810. Thecomputer 840 provides a digital image signal of thedisplay unit 110, that is, animage signal 830 corresponding to the aforementionedvirtual image 212. Theprocessing unit 810 generates animage adjustment signal 820 according to the projection signal 911 or the feedback signal 912 of thesensing unit 161. Theprocessing unit 810 transmits theimage adjustment signal 820 to thecomputer 840.
