[0025] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0026] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0027] The image processing circuit, method and electronic device provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0028] With the development of society, especially the advent of the 5G era, smartphones are becoming more and more popular, and their functions are becoming more and more powerful. In order to provide more high-quality services and experiences, the full-screen solution is the general trend. However, due to the existence of some sensors such as the front camera, there is no mature solution to achieve a complete full-screen. At present, in order to maximize the screen-to-body ratio in the market, the main methods of screen holes or grooves, or mechanical pop-up or sliding methods are used; in addition, there is another full-screen solution, which is the under-screen camera technology. There are many difficulties in the under-screen camera technology. In order to make the image quality of the electronic device clear and undistorted, it is necessary to maximize the transmittance of the screen area corresponding to the camera. In order to improve the transmittance of the screen area, it is necessary to reduce the sub-pixel area of ​​the screen area, or sacrifice the pixel resolution of the screen area, which will cause a significant difference between the display effect of the screen area corresponding to the camera and other areas of the screen, including the brightness, color, resolution, etc. of the screen area.

[0029] In order to solve the above problems, in an embodiment of the present application, the image processing circuit may include a main control chip and a display chip, the main control chip is connected to the display chip; and the main control chip can be used to generate a first image displayed in the first screen area of ​​the display screen; and the display chip can be used to perform compensation processing on the image parameters of the first image to obtain a second image, and send the second image to the display screen; wherein the pixel array structure of the first screen area is different from the pixel array structure of the second screen area of ​​the display screen; the difference between the display parameters of the second image in the first screen area and the display parameters of the third image in the second screen area is within a preset range. Through the image processing circuit, since the display chip can perform compensation processing on the image parameters of the first image displayed in the first screen area, the difference between the display parameters of the second image in the first screen area and the display parameters of the third image in the second screen area is within a preset range; therefore, the difference between the display effects caused by different pixel array structures of the display screen can be effectively reduced, thereby improving the display effect of the electronic device.

[0030] Embodiment 1

[0031] The embodiment of the present application provides an image processing circuit, Figure 1 FIG. 2 shows a schematic diagram of the structure of an image processing circuit provided by an embodiment of the present application. Figure 1 As shown, the image processing circuit provided in the embodiment of the present application may include a main control chip 10 and a display chip 11, and the main control chip 10 and the display chip 11 are connected.

[0032] Optionally, in an embodiment of the present application, the main control chip can be used to generate a first image displayed in a first screen area of ​​the display screen.

[0033] In the embodiment of the present application, the main control chip can be used to generate (draw) a first image based on the acquired image data.

[0034] Optionally, in an embodiment of the present application, after generating the first image, the main control chip can send the first image to the display chip; the display chip can be used to perform compensation processing on the image parameters of the first image after receiving the first image, obtain a second image, and send the second image to the display screen.

[0035] Optionally, in an embodiment of the present application, after generating the first image, the main control chip can convert the first image into a Mobile Industry Processor Interface (MIPI) signal to send the first image to the display chip; after obtaining the second image, the display chip can convert the second image into a MIPI signal to send the second image to the display screen.

[0036] Optionally, in an embodiment of the present application, the display chip can save the processed second image to a cache area (DRAM Frame buffer) of the display chip, and transmit the second image in the cache area to the cache area of ​​the screen in the form of a MIPI signal to facilitate displaying the second image on the screen.

[0037] Optionally, in the embodiment of the present application, the display chip may be a chip provided in the electronic device and capable of processing the first image independently. The display chip may include a digital signal processing (DSP) module.

[0038] Optionally, in the embodiment of the present application, the display chip performing compensation processing on the image parameters of the first image may include: the display chip adjusting the image parameter values ​​of the first image.

[0039] It should be noted that, in the embodiment of the present application, the purpose / function of the display chip performing compensation processing on the image pixel parameters of the first image is: by compensating the image parameters of the first image, the influence of the pixel array structure of the first screen area on the image display effect can be reduced, thereby improving the display effect of the processed first image (i.e., the second image) in the first screen area, and reducing the difference between the display effect of the first screen area and the display effect of the second screen area.

[0040] In the embodiment of the present application, the pixel array structure of the first screen area is different from the pixel array structure of the second screen area of ​​the display screen.

[0041] Optionally, in the embodiment of the present application, the different pixel array structures may be different in the number, arrangement density, arrangement method or pixel size of pixel units included in the pixel array structure.

[0042] Optionally, in an embodiment of the present application, the pixel array structure of the first screen area can be a red green blue green RGBG (Red Green Blue Green, RGBG) structure, a red green blue red RGBR (Red Green Blue Red, RGBR) structure, or a red green blue blue RGBB (Red Green Blue Blue, RGBB) structure, or any other possible pixel array structure with reduced pixels.

[0043] For example, taking the pixel array structure of the first screen area as an RGBG structure, the electronic device can retain all pixels of the G (green) channel in the pixels of the first screen area, and retain the pixels of the R (red) channel and the B (blue) channel in the pixels of the first screen area at intervals, thereby saving 1 / 3 of the number of pixels in the first screen area.

[0044] Optionally, in an embodiment of the present application, the pixel array structure of the second screen area can be a pixel array structure with a reduced number of pixels; or, the pixel array structure of the second screen area can be a pixel array structure with a full number of pixels, for example, the pixel array structure of the second screen area is a red, green, blue RGB (Red Green Blue, RGB) structure.

[0045] The pixel array structure of the first screen area and the pixel array structure of the second screen area are exemplarily described below with reference to the accompanying drawings.

[0046] For example, Figure 2 As shown in (a), the screen of the electronic device includes a first screen area 21 and a second screen area 22; wherein the screen area 23 includes a portion of the first screen area 21 and a portion of the second screen area 22; Figure 2 (b) in the figure is a schematic diagram of the pixel array structure of the screen area 23. It can be seen that the screen area 23 includes a part of the first screen area 21, an area 24 (the dotted box part) and a part of the second screen area 22, and the pixel array structure of the area 24 is an RGBG structure, and the pixel array structure of the area 25 is an RGB structure; and in order to improve the transmittance of the first screen area 21, some areas (blank areas) in the area 24 are not set with pixels, while all areas in the area 25 are set with pixels.

[0047] In the embodiment of the present application, a difference between a display parameter of the second image in the first screen area and a display parameter of the third image in the second screen area is within a preset range.

[0048] Optionally, in the embodiment of the present application, the preset range may be a system default or may be set based on experience.

[0049] It can be understood that the difference between the display parameters of the second image in the first screen area and the display parameters of the third image in the second screen area is within a preset range, that is, the display parameters of the second image in the first screen area are similar to the display parameters of the third image in the second screen area, and are difficult to distinguish with the naked eye.

[0050] Optionally, in an embodiment of the present application, the above-mentioned image parameters may include image resolution, the above-mentioned display parameters may include display resolution, and the display chip may be specifically used to: compensate the image resolution of the first image through a surface plasmon resonance SPR (Surface Plasmon Resonance, SPR) algorithm to obtain a second image.

[0051] In the embodiment of the present application, a difference between a display resolution of the second image in the first screen area and a display resolution of the third image in the second screen area is within a preset resolution range.

[0052] Optionally, in the embodiment of the present application, the preset resolution range may be a system default.

[0053] It can be understood that the difference between the display resolution of the second image in the first screen area and the display resolution of the third image in the second screen area is within the preset resolution range, that is, the display resolution of the second image in the first screen area is similar to the display resolution of the third image in the second screen area.

[0054] The following describes in detail a specific method for obtaining a second image by compensating the image resolution of a first image using an SPR algorithm on a display chip.

[0055] Optionally, in an embodiment of the present application, the display chip can determine M first pixels from the first image based on the pixel array structure of the first screen area, and the M first pixels correspond to blank areas in the first screen area where no pixels are set, and M can be a positive integer.

[0056] It can be understood that since the first image is displayed in the first screen area, the display chip can determine the M first pixels corresponding to the blank area in the first image based on the position of the blank area where no pixels are set in the first screen area.

[0057] Optionally, in an embodiment of the present application, after determining M first pixels, the display chip can determine, for each first pixel, at least one second pixel in the first row that is of the same pixel type as the first pixel and is closest to the first pixel, wherein the first row is a row in the first image that includes the first pixel; and weightedly allocate the pixel value of the first pixel to the at least one second pixel, thereby obtaining a second image.

[0058] Optionally, in the embodiment of the present application, the pixel type may be any possible type such as R (red) type, G (green) type, B (blue) type or W (white) type.

[0059] Optionally, in the embodiment of the present application, the display chip may determine the number of the at least one second pixel according to the pixel array structure of the first image.

[0060] The following is an exemplary description of a method for a display chip to determine at least one second pixel for a first pixel in conjunction with the accompanying drawings.

[0061] Exemplarily, the image pixel structure of the first image is as follows: Figure 3As shown, pixel 31 is a first pixel in the first image (i.e., an image area corresponding to a blank area in the first screen area where no pixels are set), then the electronic device can determine that row 30 (i.e., the first row) including pixel 31 in the first image includes two pixels of the same pixel type as pixel 31 and the closest distance, namely pixel 32 and pixel 33 (i.e., at least one second pixel).

[0062] Optionally, in the embodiment of the present application, for each second pixel in the at least one second pixel, the display chip can determine the pixel value assigned to the second pixel by the first pixel according to a weight w corresponding to the second pixel, that is, the pixel value assigned to the second pixel by the first pixel is: g*w. If the pixel value g of the second pixel is greater than or equal to the pixel value h of the first pixel, then the weight w=g:h; if the pixel value g of the second pixel is less than the pixel value h of the first pixel, then the weight w=h:g.

[0063] It can be understood that after the display chip compensates the image resolution of the first image through the SPR algorithm, the pixel value weightedly allocated to each second pixel in the first image includes: the sum of the pixel values ​​of each first pixel corresponding to the second pixel weightedly allocated to the second pixel.

[0064] For example, Figure 3 As shown, pixel 31 and pixel 34 are both first pixels in the first image, then: the display chip can weight the pixel value of pixel 31 to pixel 32 and pixel 33 (i.e., the pixel type of pixel 31 is the same as that of pixel 31 in the first row and at least one second pixel that is closest to it), and weight the pixel value of pixel 34 to pixel 33 and pixel 35 (i.e., the pixel type of pixel 34 is the same as that of pixel 34 in the first row and at least one second pixel that is closest to it). Among them, if the display chip weights the pixel value of pixel 31 to the pixel value of pixel 33 as a, and the display chip weights the pixel value of pixel 34 to the pixel value of pixel 33 as b, then the pixel value weighted to pixel 33 is a+b. It can be understood that if the original pixel value of pixel 33 is c, then the pixel value of pixel 33 after the compensation process is performed on the pixel parameters of the first image is a+b+c.

[0065] It should be noted that, in the embodiment of the present application, for each second pixel in the first image, after the display chip compensates for the image resolution of the first image through the SPR algorithm, the pixel value of a second pixel includes: the total pixel value (for example, the above-mentioned pixel value a+b) allocated by all first pixels corresponding to the second pixel (the corresponding manner is: the pixels that are in the same row as the first pixel and have the same pixel type as the first pixel and are closest to the first pixel) + the pixel value of the second pixel itself.

[0066] Optionally, in an embodiment of the present application, the display chip may include an SPR algorithm module, so that after receiving the first image sent by the main control chip, the display chip can compensate for the image resolution of the first image through the SPR algorithm module to obtain a second image.

[0067] In the embodiment of the present application, since the display chip can be used to compensate the image resolution of the first image through the SPR algorithm to obtain the second image, and the difference between the display resolution of the second image in the first screen area and the display resolution of the third image in the second screen area is within the preset resolution range, it is possible to improve the transmittance of the first screen area while being able to display a resolution similar to that of other screen areas in the first screen area, so that the image has better clarity in the first screen area. Thus, the difference between the display effect of the first screen area and the display effect of the second screen area can be reduced.

[0068] Optionally, in an embodiment of the present application, the above-mentioned image parameters may include image brightness, the above-mentioned display parameters may include display brightness, and the display chip may be specifically used to: adjust the first image brightness of the first image to the second image brightness to obtain the second image.

[0069] In the embodiment of the present application, the difference between the display brightness of the second image in the first screen area and the display brightness of the third image in the second screen area is within a preset brightness range.

[0070] Optionally, in the embodiment of the present application, the preset brightness range may be a system default.

[0071] It can be understood that the difference between the display brightness of the second image in the first screen area and the display brightness of the third image in the second screen area is within the preset brightness range, that is, the display brightness of the second image in the first screen area is similar to the display brightness of the third image in the second screen area.

[0072] Optionally, in the embodiment of the present application, the brightness of the second image may be the average brightness of the first image.

[0073] Optionally, in the embodiment of the present application, the average brightness of the first image may be an average brightness of all pixels in the first image.

[0074] The following describes in detail a specific method in which the display chip adjusts the first image brightness of the first image to the second image brightness to obtain the second image.

[0075] Optionally, in the embodiment of the present application, the display chip may adjust the brightness of each pixel in the first image to the brightness of the second image to obtain the second image.

[0076] For example, if the display chip determines that the average brightness of all pixels in the first image (i.e., the brightness of the second image) is c, the display chip can adjust the brightness of each pixel in the first image to c, thereby adjusting the brightness of the first image to c and obtaining the second image.

[0077] Optionally, in an embodiment of the present application, the display chip may include a De-Mura algorithm module for eliminating unevenness, so that after the display chip receives the first image sent by the main control chip, it can compensate for the image brightness of the first image through the De-Mura algorithm module to obtain a second image, thereby achieving a sufficient amount of compensation at the pixel level to achieve an effect of relatively consistent brightness between the first screen area and the second screen area, thereby reducing the phenomenon of uneven brightness of the screen display.

[0078] In the embodiment of the present application, since the display chip can be used to adjust the first image brightness of the first image to the second image brightness to obtain the second image, and the difference between the display brightness of the second image in the first screen area and the display brightness of the third image in the second screen area is within a preset brightness range, it is possible to improve the transmittance of the first screen area while displaying a brightness similar to that of other screen areas in the first screen area, thereby reducing the difference between the display effect of the first screen area and the display effect of other screen areas.

[0079] Optionally, in an embodiment of the present application, the display chip may compensate for the image resolution of the first image through an SPR algorithm, and / or the display chip may adjust the first image brightness of the first image to the second image brightness; when the display chip performs compensation processing on both the image resolution and the image brightness of the first image, the embodiment of the present application does not limit the order in which the compensation processing is performed.

[0080] It should be noted that in the embodiment of the present application, the display chip is used to compensate for the resolution difference and brightness difference between the first screen area and the second screen area as an example. In actual implementation, since the pixel array structure or size of the under-screen display area (i.e., the first screen area) is generally quite different from that of the normal display area (i.e., the second screen area), there will be edge jaggedness or color cast between the first screen area and the second screen area; in this case, the display chip can set a specific algorithm module to perform pixel-level compensation and optimization for edge jaggedness or color cast, which can be determined according to actual usage requirements and is not limited in the embodiment of the present application. In other words, the display chip can perform pixel-level compensation and optimization for any possible display difference between the first screen area and the second screen area to reduce the difference in display effect between the first screen area and the second screen area.

[0081] In the image processing circuit provided in the embodiment of the present application, since the display chip can perform compensation processing on the image parameters of the first image displayed in the first screen area, the difference between the display parameters of the second image in the first screen area and the display parameters of the third image in the second screen area is within a preset range; therefore, the difference between the display effects caused by different pixel array structures of the display screen can be effectively reduced, thereby improving the display effect of the electronic device.

[0082] Optionally, in the embodiment of the present application, the main control chip can also be used to generate a third image displayed in the second screen area and send the third image to the display screen.

[0083] In the embodiment of the present application, the main control chip can generate (draw) a third image based on the acquired image data.

[0084] In the embodiment of the present application, the third image and the above-mentioned first image may be images of different areas in an interface.

[0085] For example, the first image and the third image are images of different areas in the same session interface generated by the main control chip. The display area in the screen corresponding to the first image is the first screen area, and the display area in the screen corresponding to the third image is the second screen area.

[0086] Optionally, in the embodiment of the present application, after generating the third image, the main control chip may convert the third image into a MIPI signal to send the third image to the display screen.

[0087] Optionally, in an embodiment of the present application, the main control chip may send the third image to a cache area of ​​the screen so as to display the third image on the screen.

[0088] It can be understood that when the cache area of ​​the screen includes the second image and the third image, the electronic device can control the screen to display the second image in the first screen area and display the third image in the second screen area.

[0089] Optionally, in an embodiment of the present application, when the pixel arrangement structure of the second screen area is also an arrangement structure for saving the number of pixels in the second screen area, compensation processing can be performed on the pixel parameters of the third image through another display chip, and the processed third image can be displayed in the second screen area.

[0090] The present application also provides an image processing method, which is applied to the image processing circuit in the above-mentioned embodiment 1. Figure 4 FIG. 1 is a flow chart of an image processing method provided by an embodiment of the present application. Figure 4 As shown, the image processing method provided in the embodiment of the present application may include the following steps 401 to 403.

[0091] Step 401: The main control chip generates a first image to be displayed in a first screen area of ​​a display screen.

[0092] Step 402: The display chip performs compensation processing on image parameters of the first image to obtain a second image.

[0093] Step 403: The display chip sends the second image to the display screen.

[0094] In the embodiment of the present application, the pixel array structure of the first screen area is different from the pixel array structure of the second screen area of ​​the display screen.

[0095] In the embodiment of the present application, a difference between a display parameter of the second image in the first screen area and a display parameter of the third image in the second screen area is within a preset range.

[0096] Optionally, in the embodiment of the present application, the above-mentioned image parameters may include image resolution, and the above-mentioned display parameters may include display resolution, then the above-mentioned step 402 may be specifically implemented through the following step 402a.

[0097] Step 402a: The display chip compensates the image resolution of the first image by using an SPR algorithm to obtain a second image.

[0098] In the embodiment of the present application, a difference between a display resolution of the second image in the first screen area and a display resolution of the third image in the second screen area is within a preset resolution range.

[0099] In the embodiment of the present application, since the display chip can compensate the image resolution of the first image through the SPR algorithm to obtain the second image, and the difference between the display resolution of the second image in the first screen area and the display resolution of the third image in the second screen area is within the preset resolution range, it is possible to improve the transmittance of the first screen area while being able to display a resolution similar to that of other screen areas in the first screen area, so that the image has better clarity in the first screen area.
