Description of the Invention: [Technical Field of the Invention] The present invention is directed to an image processing method, and more particularly, to a method for adjusting the resolution. [Prior Art] With the development of digital cameras, photography is no longer expensive (4) #^ Users can take the desired images at will to record a memorable moment or scene. • When you are doing _, the photos of the users want to be clearly visible. Therefore, when shooting a target (which can be a landscape, a person, or an item), adjust the focus and brightness of the object to obtain a satisfactory photo. The advancement of technology' digital cameras mostly provide the function of automatically setting money like parameters. In general, the number _ machine touches the target to calculate the appropriate camera parameters. In the resolution of the image of the photographer, it is still only possible for the user to adjust the camera by the digital camera before taking the photo. —^' causes the viewer to not change the resolution setting, and the images captured for each occasion, each theme, or each of the main characters will have the same resolution. The digital camera has limited storage space. When the resolution setting is high, the number of images that can be taken is relatively small. Moreover, when sorting out afterwards, it is often found that there are photos that are useless and abandoned, but they are left to occupy the library resources, for example: the notebook on the camera ^ heart, hard disk on the computer, burning Individuals on a disc or on the Internet are thin. Conversely, in order to save space in the storage space and choose to use a lower resolution, the details of the good picture >1 are sacrificed. - In order not to miss any details, when using the highest resolution, the effect is inferior, 201201571 car difference or very poor, 3⁄4 piece, it will be less or extremely priceless _ occupying the space of the camera storage media, greatly affecting The number of shots can be taken. SUMMARY OF THE INVENTION In the above discussion, the present invention provides a training method for solving the problem of the prior art by solving the problem of the prior art. The resolution_the whole method disclosed in the present invention is an image capturing device. The video device includes a camera module and a storage unit. First, the image is obtained from the image with the first resolution. After praying $$, the amount of objects analyzed will be compared to one or more clever values. When the amount of the object to be analyzed is less than - 槛 n 槛 value, the corresponding 槛 value will be the resolution of the image; or, the resolution of the image manipulation device will be lowered from the first resolution to the second resolution 'And re-image with her second resolution. 4, the image with the second resolution is stored in the storage unit. The amount of objects read in the field is larger than the scale of all the thresholds, and the image with the degree of resolution is stored in the storage unit. The amount of objects in the μ image can be obtained by first performing a marginalization process to calculate the amount of the edge of the image in the image after the marginalization, so that the calculated amount of the component is calculated. Contains f as the amount of the object. According to the resolution of (4), the Na method can be used to determine the image storage time. The image is stored in the image of the analysis. The second is that 'Min is Wei Fangyu. (4) Cheng is the shirt. The analysis of the device further utilizes the health resources. ° 201201571 By; ^^ The description of the present invention (4) and the description of the following embodiments are used to explain the principle of the spirit disk of the present invention, and the scope is further explained. 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 The time of capturing 2^ is to zoom the image obtained or to determine whether to lower the image and then use the storage resources effectively. Among them, the image capture device can be a digital city, a digital device, or an electronic device with a group (for example, a mobile phone or a computer). Please refer to "1st picture", image capture & i (8) can include: camera module ιι〇, storage unit 13〇 and processing unit (9). The camera module 11A includes a lens group (1) and a light sensing element 114. The lens group 112 is used to adjust the focal length of the subject. The photosensitive element 114 is provided corresponding to the lens and the group 112. The photosensitive element ιΐ4 can receive the optical signal corresponding to the target object and its surrounding scenery through the lens group m, and according to the received optical fiber, the image of the target image can be applied to the target image. In other words, the photosensitive element 114 can capture an image of the framing plane via the set 112. The processing unit 15 is electrically connected to the photosensitive element 1M and the storage unit 13A. The processing unit 150 can control the operation of the lens group 112 and the photosensitive element 114, and store the captured image in the storage unit 130. Here, the processing unit 150 can also analyze the amount of the image of the captured image and select the resolution of the image-forming device according to the amount of the reading component of 201201571.解析, '换换5' According to the resolution of the present invention, the whole method can be implemented on the image capturing device (10). That is, the code for performing the breaking method according to the present invention can be stored in the processing unit 15 of the image capturing device 100 in the image capturing apparatus, and the stored program horse is read and executed so that景 y like the couching device 1GG shop · According to the (four) riding degree _ whole method. . The processing unit 150 can be implemented by one or more processors, such as a digital signal processor (DPS). The storage unit (10) can be implemented by one or more storages. The reservoir can be non-volatile memory or hair memory. / Here, the image to be divided can be a preview image or a captured image. The preview image refers to the image captured by the image browning device during the preview phase or the focusing phase. The image captured by the image capturing device 1 is captured during the shooting phase. In general, the operation of the image manipulation device can be divided into a preview phase (We VleW), a focus phase (aut0 focusing), and a shooting phase. The preview phase refers to the moment before the user views the image of the device. In the preview phase, the user can preview the framing screen through the display (not shown) of the image manipulation device 8 (8). The focus phase refers to the moment when the user presses the shutter button of the image capture device halfway. In the pre-focus phase, the image capturing device 1 作为 takes one or more of the objects in the framing picture as the target object, and adjusts the object distance between the lens group i 12 and the target object, and the user can pass through the image 掏Take the display of the device 1( (not shown) to preview the finder screen after the 201201571 is in focus (that is, after the object distance adjustment is completed). • The shooting phase refers to the moment when the user fully presses the shutter button of the image capture device 1〇〇. During the shooting phase, the image capturing device 1 〇 captures the current viewing frame through the camera module 11 and records the captured viewing frame as an image. "2A and 2B" is a flowchart of a method of adjusting the resolution according to the second embodiment of the present invention. Referring to "Fig. 2A and 2B", first, the camera module 11 is used to take an image corresponding to a plurality of objects immediately before the image capturing device (step 210). This image has a first resolution. The first resolution may be the resolution currently set by the image capture device 100 or the upper limit of the resolution of the image capture device 1 (this upper limit may be determined by the capabilities of the image capture device 1). Such objects may be at least one of features such as a face, a scum, an animal, a plant, a mountain, a cloud, a stone, a flowing water, a traffic tool, a sign, and a specific item. Then, the amount of the object in the captured image is analyzed (step 22). And use the analyzed object quantity to judge the complexity of the image, that is, whether the object quantity meets the set condition (step 23〇). Here, the complexity of the image refers to the amount of detail (i.e., the subject matter) that appears in the image. When the complexity of the image is relatively high, the image having the first resolution is stored in the storage unit 130 (step 24). When the complexity of the image is relatively high, the resolution of the image of the thorn is reduced from the first resolution to the second resolution (step zhou; the setting of the resolution of the image side device is lowered from the first resolution) It is the second riding degree (step 252), and after the adjustment, the image is captured again by the camera module 11 (step 254). At this time, the shadow 7 201201571 image has the second resolution. The resolution image is stored in the storage list (4) (step execution marginalization and falsification). In step 22, the processing unit 150 = edge recording can be used to record the image edge track (_222), and then Count 2 = Moxibustion ΓΓ 中 中 中 中 中 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( The number or edge of the element is formed. Further, in step 220, the identification process may be performed by the processing unit 150, and the number of objects in the image obtained by the image is recognized and calculated by (4) the number of objects calculated as (4) The amount of the object. Step 230 towel 'available - the door value or The relationship between the plurality of threshold values and their respective resolution adjustment data (for example, the correspondence table between the threshold value and the resolution adjustment asset) is compared with the analyzed object amount to determine the complexity of the image. In the case of a single threshold, the reference to the 5th and 5th maps can be compared with the bribes (step 232). 4 When the amount of objects is greater than or equal to the threshold value, the complexity of the image is high, that is, the resolution is not performed ( Adjustment of the resolution of the image or the setting of the resolution of the image display device (step 240) 201201571 When the value of the object is small and the value of m is small, the image resolution is low, and the resolution of the image is analyzed from the first analysis. The degree is lowered to the second resolution (step 25g). Alternatively, the resolution of the side-to-side transposition is lowered from the first _degree to the second resolution (step 252), and the second is re-taken. The resolution image (step 254). In step 250 & step 252, the current resolution (the resolution of the image or the resolution of the image capture device) may be determined at a specific magnification when the complexity of the image is low. Setting) down. In other words The first resolution may be a specific magnification of the second resolution, for example, one, two or more times, etc. For example, assume the current resolution of the image capturing device 100 (ie, the first resolution) ) is set to 6 MP, and the specific magnification is preset to - times. At this time, the resolution of the image obtained by the image capturing device 110 is 6Mp. The result of analysis and judgment is the complexity of the image. When the degree is low, the processing unit 150 performs a resolution adjustment procedure to reduce the resolution of the image from 6 (ie, the first resolution) to 3 MP (ie, the second resolution). Alternatively, the processing unit The resolution adjustment program is executed to set the current resolution (i.e., the first resolution) of the image display device 100 from the setting of 6 MP to 3 MP (i.e., the second resolution). In step 250 and step 252, the resolution of the image or the resolution of the image manipulation device 100 may be set according to the difference between the specific level and the setting option of the resolution of the image. The first resolution adjustment is low to the second resolution. In other words, the first resolution differs from the second resolution by a specific level, for example, one level, two levels, or three levels or more. For example, suppose the resolution of the resolution provided by the image capturing device 1 is 201201571, which is 1 〇 MP (Million 昼 )), 8MP, 6MP, 4MP, 3MP, 2MP — 1MP'. (ie 'D-resolution' is set to 8MP, and the specific level is preset to one level. At this time, when it is determined that the complexity of the image is low, the processing unit Ais performs a resolution adjustment procedure to convert the resolution of the image from 8Mp (ie, the first resolution) to 6MP (ie, the second resolution). Or the current resolution of the image capture farm 100 (ie, the 'first resolution') is set from 8 MP to 6 MP (ie, the second resolution). Here, the image capturing device 100 can additionally set the adjusted resolution (ie, the second resolution) to be less than the lower limit of the resolution of the image detecting device 1 (this lower limit can be determined by the capability of the image capturing device 100) . Furthermore, the minimum value (i.e., the second resolution) of the adjustable resolution can be set by the user according to the resolution of the resolution provided. When the value of the second resolution of the predetermined adjustment is smaller than the lower limit of the resolution of the image-receiving device 1GG or the minimum value of the adjustable resolution of 0 and 0, the lower limit of the resolution of the image manipulation device 100 is directly taken or The minimum value of the set adjustable resolution is set to a value of 2 second resolution. In other words, 'When the value of the second resolution of the predetermined adjustment is smaller than the lower limit of the resolution of the image capturing device 100 or the minimum value of the set adjustable resolution, 'the riding degree is light _ is the resolution from the first riding degree Turn down to the lower limit of the resolution of the image-to-device leak or the minimum of the set resolution of the machine. Referring to "Figures 6A and 6B", it is also possible to search for a relationship information by the amount of objects analyzed (step 234). This relationship information includes multiple threshold values that differ from each other and the resolution adjustment data corresponding to each threshold of 201201571. Different = double analysis represents different adjustment results (ie, adjust the mark. Adjusted here _ can be - value or - state Ί value, specific magnification level (based on image. Yellow resolution device 100 resolution setting) Option) For convenience of description, three threshold values are used to describe the values of m thresholds from large to small, which are called the first threshold, the second threshold, and the third threshold.

When the analyzed object quantity is less than the second threshold but greater than or equal to the third When the threshold value is set, the resolution is adjusted according to the resolution corresponding to the second threshold value, and the resolution is lowered from the first resolution to the second resolution (steps 250-2 and 252-2). At this time, the second resolution Corresponding to the resolution adjustment data corresponding to the second threshold value. When the analyzed object quantity is less than the third threshold value, the data is adjusted according to the resolution corresponding to the second threshold value, and the resolution is lowered from the first resolution. The second resolution is (step 250-3 and step 252-3). At this time, the second resolution is adjusted according to the resolution corresponding to the third threshold value. 11 201201571 For the object of analysis, when the object is analyzed When the amount is less than at least one door pinch value, The single cymbal 150 will be less than at least one swaying value corresponding to the smallest gate value of the less than the threshold value (step 250 and step 252). Here, when the duty (4) second scalar value is small, miscellaneous When the lower limit of the riding degree of the device or the minimum value of the adjustable resolution can be set, the minimum value of the resolution of the image age device or the minimum value of the adjustable resolution can be directly set as the second resolution. In other words, when the value of the second resolution adjusted by the thief is less than the lower limit of the resolution of the video recording device or the minimum value of the set resolution, the image adjusted is lowered from the first resolution to the image. The lower limit of the resolution of the device 1 (8) or the minimum value of the adjustable resolution can be set. For the sake of clarity, the threshold value and its corresponding resolution adjustment data can be as shown in the following table. The relationship is not limited by the present invention. Table 1 threshold value ^ a threshold value ^ two threshold value in other words, the resolution adjustment data ^ one adjustment result ¥ two adjustment results _ table can be the door ^ value and resolution adjustment examples Say 'the first threshold The value can be set to 50%, and the second planting value can be set to 30%. The larger the value is, the higher the complexity is, which is not the limitation of the present invention. The first adjustment result can be set to one lower. Level, and the second adjustment result can be set to lower the two levels.
