[0021] The image processing method for the smart terminal provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0022] Embodiment 1

[0023] refer to Figure 1 , Figure 1 A hardware structure diagram of an image processing circuit of this embodiment is provided, wherein the image processing circuit 100 includes a main control chip 101 and a display chip 102 , and the main control chip 101 is connected to the display chip 102 .

[0024] In this embodiment, the main control chip 101 is used to output first image data and resolution data according to the data to be processed.

[0025] In an example, the main control chip 101 can be an application processor (AP) chip, hereinafter referred to as the AP end. The AP end has a graphics processing unit (GPU) and a display processing unit (DPU). In actual applications, the GPU will draw image data with original resolution according to the scene and send it to the DPU for data synthesis. The DPU will hand over the synthesized image data with original resolution to an independent display chip. At the same time, the AP end can obtain the screen display resolution of the smart terminal according to the system configuration of the smart terminal.

[0026] In one example, the data to be processed may be scene information acquired by the AP through a camera module of a terminal device, or video data acquired from a cloud or local storage. The first image data may be image data synthesized by the DPU based on image data drawn by the GPU.

[0027] Among them, since the purpose of this embodiment is to reduce the data processing amount of the processor in the terminal device and improve efficiency, when the GPU draws the image data of the original resolution according to the scene, the original resolution can be made as small as possible, thereby reducing the data processing amount of the main control chip in image processing. In other words, the first image data output by the main control chip has a smaller original resolution.

[0028] In one example, since the resolutions of display screens of different terminal devices may be different, and the resolutions of multiple display screens of the same terminal device may also be different, the main control chip can obtain the resolution data of the display screen corresponding to the terminal device by obtaining the system configuration information of the terminal device. Thus, by processing the first image data, the output image resolution can be adapted to the display screen of the terminal device.

[0029] In this embodiment, the resolution data includes the target resolution of the first image data, which is the resolution of the display screen of the terminal device. The resolution data output by the main control chip 101 may include the original resolution of the first image data, or the first image data may be directly sent to the display chip 102, and the display chip 102 obtains its original resolution according to the first image data.

[0030] In this embodiment, the display chip 102 is used to output second image data based on the first image data and the resolution data, wherein the resolution of the second image data is determined based on the resolution data.

[0031] For example, the resolution data includes the original resolution and the target resolution of the first image data. The original resolution is 720*1800 and the target resolution is 1080*1440. Then the resolution of the second image data output by the display chip is 1080*1440.

[0032] The image processing circuit provided in this embodiment includes a main control chip and a display chip. The first image data and resolution data are output through the main control chip. The second image data is output through the display chip based on the first image data and the resolution data. The resolution of the second image data is determined based on the resolution data. The resolution processing process of the first image data is completed by the display chip, which can greatly reduce the data processing amount of the main control chip, improve the working efficiency of the main control chip, and thus reduce the power consumption of the terminal device.

[0033] It can be seen from the above embodiments that the resolution data output by the main control chip may include the original resolution of the first image data, or the first image data may be directly sent to the display chip, and the display chip obtains its original resolution according to the first image data.

[0034] Therefore, in the case where the resolution data includes the original resolution and the target resolution of the first image data, the display chip is specifically used to: perform scaling processing on the first image data based on the original resolution and the target resolution, and output the second image data; wherein the resolution of the second image data is the same as the target resolution. For example, the original resolution of the first image data is 720*1800, and the target resolution is 1080*1440. The display chip performs scaling processing on the resolution of the first image data, and outputs the second image data with the resolution of the target resolution of 1080*1440. This method can obtain the second image data more quickly.

[0035] In the case where the resolution data includes the target resolution of the first image data, the display chip is specifically used to: obtain the original resolution of the first image data according to the first image data; scale the first image data based on the original resolution and the target resolution, and output the second image data; wherein the resolution of the second image data is the same as the target resolution. For example, the target resolution of the first image data is 1080*1440, and the display chip performs pixel analysis on the first image data to obtain that the original resolution of the first image data is 720*1800. The display chip scales the resolution of the first image data and outputs the second image data with a resolution of the target resolution of 1080*1440. This method can further reduce the amount of data processing by the main control chip.

[0036] In one scenario, when a low-resolution image is directly scaled to a high-resolution screen, the noise in the details is often too high due to information loss, making the image blurry. Therefore, in order to solve this problem, in this embodiment, before the display chip 102 performs scaling processing on the first image data, the display chip 102 is also used to: when the difference between the original resolution and the target resolution is greater than a preset threshold, perform super-resolution processing on the first image data. Performing super-resolution processing on the first image data can complement the detail information of the first image data to avoid information loss.

[0037] In a feasible example, the preset threshold can be set by system developers or by users in a customized manner, which is not limited here. In this embodiment, super-resolution processing is to enlarge the resolution, such as enlarging a 512*512 picture to a 1024*1024 picture.

[0038] In this embodiment, the display chip performs super-resolution processing and optimization on image data having a large difference between the resolution of the first image data and the target resolution, thereby further obtaining image data with better display effect.

[0039] In one scenario, the terminal device may have one display screen or multiple display screens. For example, when the display screen of the terminal device is a dual-screen display, the image data to be displayed on the two different display screens and the corresponding resolutions may be different.

[0040] At this time, the first image data includes a first sub-image and a second sub-image, and the resolution data includes first sub-resolution data and second sub-resolution data, the first sub-resolution data is the resolution data corresponding to the first sub-image, and the second sub-resolution data is the resolution data corresponding to the second sub-image. The first sub-resolution data and the second sub-resolution data may be the same or different.

[0041] In this embodiment, the display chip 102 is specifically configured to output a third sub-image based on the first sub-image and the first sub-resolution data, wherein the resolution of the third sub-image is determined based on the first sub-resolution data.

[0042] For example, the first sub-resolution data includes an original resolution of 1080*1440 and a target resolution of 720*1800. The display chip reduces the resolution of the first sub-image and outputs a third sub-image with a resolution of the target resolution of 720*1800.

[0043] In this embodiment, the display chip 102 is specifically configured to output a fourth sub-image based on the second sub-image and the second sub-resolution data, wherein the resolution of the fourth sub-image is determined based on the second sub-resolution data.

[0044] For example, the second sub-resolution data includes an original resolution of 720*1080 and a target resolution of 1500*2150. The display chip enlarges the resolution of the second sub-image and outputs a fourth sub-image with a resolution of the target resolution of 1500*2150.

[0045] This embodiment can perform different processing on display data of different display screens of the same terminal, and has higher adaptability.

[0046] In one example, the contents displayed on multiple display screens of a terminal device may be the same. For example, the terminal device includes a first display screen and a second display screen, the first display screen currently displays video playback data, and the second display screen currently displays video playback data. The contents displayed on multiple display screens of a terminal device may also be different. For example, the terminal device includes a first display screen and a second display screen, the first display screen currently displays video playback data, and the second display screen currently displays image data acquired by a shooting component. Therefore, the display chip can determine whether the contents of the first display screen and the second display screen are the same, and process the first image data according to the scene.

[0047] In this embodiment, when the image content of the first sub-image is the same as the image content of the second sub-image, the display chip 102 is specifically used to: output a third sub-image based on the target sub-image and the first sub-resolution data, and output a fourth sub-image based on the target sub-image and the second sub-resolution data, wherein the target sub-image includes the first sub-image or the second sub-image.

[0048] That is to say, when the contents of the first sub-image and the second sub-image are the same, the third sub-image and the fourth sub-image can be output according to the first sub-image or the second sub-image. It should be noted that when the contents of the first sub-image and the second sub-image are the same, if the original resolution of the first sub-image is different from the original resolution of the second sub-image, the image with the higher original resolution of the two is used as the target sub-image. For example, when the original resolution of the first sub-image is 1080*1440 and the original resolution of the second sub-image is 720*1800, since the resolution 1080*1440 is greater than the resolution 720*1800, the first sub-image is determined to be the target sub-image. By using the image with a higher original resolution as the target sub-image, more image information can be obtained, so that the output third sub-image and the fourth sub-image are clearer, thereby having a better display effect.

[0049] In this embodiment, when the image content of the first sub-image is different from the image content of the second sub-image, the display chip 102 is specifically configured to: output a third sub-image based on the first sub-image and the first sub-resolution data, and output a fourth sub-image based on the second sub-image and the second sub-resolution data. The third sub-image can be displayed on the first display screen, and the fourth sub-image can be displayed on the second display screen.

[0050] It should be noted that, in this embodiment, when the original resolution and the target resolution included in the resolution data are equal, that is, when the resolution of the first image data meets the resolution requirement of the display screen of the terminal device, the display chip is used to use the first image data as the second image data. In other words, the display chip does not process the resolution of the first image data, and directly sends the first image data to the display screen through the bypass of the display chip, which can avoid the invalid work of the display chip and reduce the overall power consumption of the smart terminal.

[0051] Embodiment 2

[0052] This embodiment provides an image processing method, which is applied to the image processing circuit provided in the first embodiment. Figure 2 , the method comprising:

[0053] S201. The main control chip outputs first image data and resolution data according to the data to be processed.

[0054] In one example, the data to be processed may be scene information acquired by the AP through a camera module of a terminal device, or video data acquired from a cloud or local storage. The first image data may be image data synthesized by the DPU based on image data drawn by the GPU.

[0055] Among them, since the purpose of this embodiment is to reduce the data processing amount of the processor in the terminal device and improve efficiency, when the GPU draws the image data of the original resolution according to the scene, the original resolution can be made as small as possible, thereby reducing the data processing amount of the main control chip in image processing. In other words, the first image data output by the main control chip has a smaller original resolution.

[0056] In one example, since the resolutions of display screens of different terminal devices may be different, and the resolutions of multiple display screens of the same terminal device may also be different, the main control chip can obtain the resolution data of the display screen corresponding to the terminal device by obtaining the system configuration information of the terminal device. Thus, by processing the first image data, the output image resolution can be adapted to the display screen of the terminal device.

[0057] In this embodiment, the resolution data includes the target resolution of the first image data, which is the resolution of the display screen of the terminal device. The resolution data output by the main control chip may include the original resolution of the first image data, or the first image data may be directly sent to the display chip, and the display chip obtains its original resolution based on the first image data.

[0058] S202: The display chip outputs second image data based on the first image data and the resolution data.

[0059] In this embodiment, the display chip is used to output second image data based on the first image data and the resolution data, wherein the resolution of the second image data is determined based on the resolution data.

[0060] For example, the resolution data includes the original resolution and the target resolution of the first image data. The original resolution is 720*1800 and the target resolution is 1080*1440. Then the resolution of the second image data output by the display chip is 1080*1440.

[0061] The image processing circuit provided in this embodiment includes a main control chip and a display chip. The first image data and resolution data are output through the main control chip. The second image data is output through the display chip based on the first image data and the resolution data. The resolution of the second image data is determined based on the resolution data. The resolution processing process of the first image data is completed by the display chip, which can greatly reduce the data processing amount of the main control chip, improve the working efficiency of the main control chip, and thus reduce the power consumption of the terminal device.

[0062] In this embodiment, when the resolution data includes the original resolution and the target resolution of the first image data, S202 includes: the display chip scales the first image data based on the original resolution and the target resolution, and outputs second image data, wherein the resolution of the second image data is the same as the target resolution.

[0063] For example, the original resolution of the first image data is 720*1800, and the target resolution is 1080*1440. The display chip enlarges the resolution of the first image data and outputs the second image data with the target resolution of 1080*1440. This method can obtain the second image data more quickly.

[0064] In this embodiment, when the resolution data includes a target resolution of the first image data, S202 includes: the display chip obtains the original resolution of the first image data based on the first image data; the display chip scales the first image data based on the original resolution and the target resolution, and outputs second image data; wherein the resolution of the second image data is the same as the target resolution.

[0065] For example, the target resolution of the first image data is 1080*1440, and the display chip performs pixel analysis on the first image data to obtain the original resolution of the first image data as 720*1800. The display chip enlarges the resolution of the first image data and outputs the second image data with the target resolution of 1080*1440. This method can further reduce the data processing amount of the main control chip.

[0066] In one scenario, when a low-resolution image is directly scaled to a high-resolution screen, the noise in the details is often too high due to information loss, making the image blurry. Therefore, in order to solve this problem, in this embodiment, when the difference between the original resolution and the target resolution is greater than a preset threshold, before scaling the first image data, the display chip also includes: performing super-resolution processing on the first image data. Performing super-resolution processing on the first image data can complete the detail information of the first image data to avoid information loss.

[0067] In a feasible example, the preset threshold can be set by system developers or by users in a customized manner, which is not limited here. In this embodiment, super-resolution processing is to enlarge the resolution, such as enlarging a 512*512 picture to a 1024*1024 picture.

[0068] In this embodiment, the display chip performs super-resolution processing and optimization on image data having a large difference between the resolution of the first image data and the target resolution, thereby further obtaining image data with better display effect.

[0069] In one scenario, the terminal device may have one display screen or multiple display screens. For example, when the display screen of the terminal device is a dual-screen display, the image data to be displayed on the two different display screens and the corresponding resolutions may be different.

[0070] Therefore, in this embodiment, the first image data includes a first sub-image and a second sub-image, and the first sub-image and the second sub-image correspond to two display screens of the terminal device respectively. The resolution data includes first sub-resolution data and second sub-resolution data, and the first sub-resolution data is the resolution data corresponding to the first sub-image, and the second sub-resolution data is the resolution data corresponding to the second sub-image. The first sub-resolution data and the second sub-resolution data may be the same or different.

[0071] In this embodiment, when the first image data includes a first sub-image and a second sub-image, S202 includes: the display chip outputs a third sub-image based on the first sub-image and the first sub-resolution data, wherein the resolution of the third sub-image is determined based on the first sub-resolution data.

[0072] For example, the first sub-resolution data includes an original resolution of 1080*1440 and a target resolution of 720*1800. The display chip reduces the resolution of the first sub-image and outputs a third sub-image with a resolution of the target resolution of 720*1800.

[0073] In this embodiment, when the first image data includes a first sub-image and a second sub-image, S202 includes: the display chip outputs a fourth sub-image based on the second sub-image and the second sub-resolution data; wherein the resolution of the fourth sub-image is determined based on the second sub-resolution data.

[0074] For example, the second sub-resolution data includes an original resolution of 720*1080 and a target resolution of 1500*2150. The display chip enlarges the resolution of the second sub-image and outputs a fourth sub-image with a resolution of the target resolution of 1500*2150.

[0075] This embodiment can perform different processing on display data of different display screens of the same terminal, and has higher adaptability.

[0076] In one example, the contents displayed on multiple display screens of a terminal device may be the same. For example, the terminal device includes a first display screen and a second display screen, the first display screen currently displays video playback data, and the second display screen currently displays video playback data. The contents displayed on multiple display screens of a terminal device may also be different. For example, the terminal device includes a first display screen and a second display screen, the first display screen currently displays video playback data, and the second display screen currently displays image data acquired by a shooting component. Therefore, the display chip can determine whether the contents of the first display screen and the second display screen are the same, and process the first image data according to the scene.

[0077] In this embodiment, when the image content of the first sub-image is the same as the image content of the second sub-image, the display chip outputs the third sub-image based on the first sub-image and the first sub-resolution data, including: the display chip outputs the third sub-image based on the target sub-image and the first sub-resolution data.

[0078] In this embodiment, when the image content of the first sub-image is the same as the image content of the second sub-image, the display chip outputs the fourth sub-image based on the second sub-image and the second sub-resolution data, including: the display chip outputs the fourth sub-image based on the target sub-image and the second sub-resolution data. The target sub-image includes the first sub-image or the second sub-image.

[0079] That is to say, when the contents of the first sub-image and the second sub-image are the same, the third sub-image and the fourth sub-image can be output according to the first sub-image or the second sub-image. It should be noted that when the contents of the first sub-image and the second sub-image are the same, if the original resolution of the first sub-image is different from the original resolution of the second sub-image, the image with the higher original resolution of the two is used as the target sub-image. For example, when the original resolution of the first sub-image is 1080*1440 and the original resolution of the second sub-image is 720*1800, since the resolution 1080*1440 is greater than the resolution 720*1800, the first sub-image is determined to be the target sub-image. By using the image with a higher original resolution as the target sub-image, more image information can be obtained, so that the output third sub-image and the fourth sub-image are clearer, thereby having a better display effect.

The third sub-image can be displayed on the first display screen, and the fourth sub-image can be displayed on the second display screen.

[0081] It should be noted that, in this embodiment, when the original resolution and the target resolution included in the resolution data are equal, that is, when the resolution of the first image data meets the resolution requirement of the display screen of the terminal device, the display chip is used to use the first image data as the second image data.

[0091] For example, the target resolution of the first image data is 1080*1440, and the second processing module of the display chip performs pixel analysis on the first image data to obtain an original resolution of 720*1800 for the first image data. The second processing module enlarges the resolution of the first image data and outputs the second image data with a resolution of the target resolution of 1080*1440. This method can further reduce the data processing amount of the main control chip.

[0092] In one scenario, when a low-resolution image is directly scaled to a high-resolution screen, the noise in the details is often too high due to information loss, making the image blurry. Therefore, in order to solve this problem, in this embodiment, when the difference between the original resolution and the target resolution is greater than a preset threshold, before scaling the first image data, the second processing module is also used to perform super-resolution processing on the first image data. Performing super-resolution processing on the first image data can complete the detail information of the first image data and avoid information loss.

[0093] Therefore, in this embodiment, when the difference between the original resolution and the target resolution is greater than a preset threshold, before the second processing module performs scaling processing on the first image data, the second processing module is further used to: perform super-resolution processing on the first image data. The detail information of the first image data can be supplemented to avoid information loss.

[0094] In one scenario, the terminal device may have one display screen or multiple display screens. For example, when the display screen of the terminal device is a dual-screen display, the image data to be displayed on the two different display screens and the corresponding resolutions are different.

[0095] Therefore, in this embodiment, the first image data includes a first sub-image and a second sub-image, and the resolution data includes first sub-resolution data and second sub-resolution data, the first sub-resolution data is the resolution data corresponding to the first sub-image, and the second sub-resolution data is the resolution data corresponding to the second sub-image.

[0096] Correspondingly, refer to Figure 4 The first processing module 1012 includes a first processing unit 1013 and a second processing unit 1014, and the first interface includes a first sub-interface TX0 and a second sub-interface TX1; the first processing unit 1013 is connected to the first sub-interface TX0, and the first processing unit 1013 is used to generate a first sub-image and a first sub-resolution data according to the data to be processed, and the first sub-interface TX0 is used to output the first sub-image and the first sub-resolution data.

[0097] In this embodiment, the second processing unit 1014 is connected to the second sub-interface TX1, and is used to generate a second sub-image and second sub-resolution data according to the data to be processed, and the second sub-interface TX1 is used to output the second sub-image and second sub-resolution data.

[0098] In this embodiment, the second processing module 1022 includes a third processing unit 1024 and a fourth processing unit 1025, and the second interface includes a third sub-interface RX0 and a fourth sub-interface RX1, the third sub-interface RX0 is connected to the first sub-interface TX0 and the third processing unit 1024 respectively, and the fourth sub-interface RX1 is connected to the second sub-interface TX1 and the fourth processing unit 1025 respectively.

[0099] The third processing unit 1024 is used to generate a third sub-image based on the first sub-image and the first sub-resolution data, wherein the resolution of the third sub-image is determined based on the first sub-resolution data. For example, the first sub-resolution data includes an original resolution of 1080*1440 and a target resolution of 720*1800, and the third processing unit 1024 reduces the resolution of the first sub-image and outputs a third sub-image having a resolution of the target resolution of 720*1800.

[0100] The fourth processing unit 1025 is used to generate a fourth sub-image based on the second sub-image and the second sub-resolution data, and the resolution of the fourth sub-image is determined based on the second sub-resolution data. For example, the second sub-resolution data includes an original resolution of 720*1080 and a target resolution of 1500*2150, and the fourth processing unit 1025 enlarges the resolution of the second sub-image and outputs a fourth sub-image with a resolution of the target resolution of 1500*2150.

[0101] In this embodiment, the third interface includes a fifth sub-interface TX2 and a sixth sub-interface TX3, the fifth sub-interface TX2 is connected to the third processing unit 1024, the sixth sub-interface TX3 is connected to the fourth processing unit 1025, the fifth sub-interface TX2 is used to output the third sub-image, and the sixth sub-interface TX3 is used to output the fourth sub-image. For example, if the terminal device includes a first display screen and a second display screen, the third sub-image can be displayed through the first display screen, and the fourth sub-image can be displayed through the second display screen.

[0102] In one example, the contents displayed on multiple display screens of a terminal device may be the same. For example, the terminal device includes a first display screen and a second display screen, the first display screen currently displays video playback data, and the second display screen currently displays video playback data. The contents displayed on multiple display screens of a terminal device may also be different. For example, the terminal device includes a first display screen and a second display screen, the first display screen currently displays video playback data, and the second display screen currently displays image data acquired by a shooting component. Therefore, the display chip can determine whether the contents of the first display screen and the second display screen are the same, and process the first image data according to the scene.

[0103] Therefore, when the image content of the first sub-image is the same as the image content of the second sub-image, the third processing unit is specifically configured to generate a third sub-image based on the target sub-image and the first sub-resolution data. The fourth processing unit is specifically configured to generate a fourth sub-image based on the target sub-image and the second sub-resolution data, wherein the target sub-image includes the first sub-image or the second sub-image.

[0104] That is to say, when the contents of the first sub-image and the second sub-image are the same, the third sub-image and the fourth sub-image can be output according to the first sub-image or the second sub-image. It should be noted that when the contents of the first sub-image and the second sub-image are the same, if the original resolution of the first sub-image is different from the original resolution of the second sub-image, the image with the higher original resolution of the two is used as the target sub-image. For example, when the original resolution of the first sub-image is 1080*1440 and the original resolution of the second sub-image is 720*1800, since the resolution 1080*1440 is greater than the resolution 720*1800, the first sub-image is determined to be the target sub-image. By using the image with a higher original resolution as the target sub-image, more image information can be obtained, so that the output third sub-image and the fourth sub-image are clearer, thereby having a better display effect.

[0105] In this embodiment, when the image content of the first sub-image is different from the image content of the second sub-image, the third processing unit is specifically configured to: output the third sub-image based on the first sub-image and the first sub-resolution data. The fourth processing unit is specifically configured to: output the fourth sub-image based on the second sub-image and the second sub-resolution data. The third sub-image can be displayed on the first display screen, and the fourth sub-image can be displayed on the second display screen.

[0106] It should be noted that, in this embodiment, when the original resolution and the target resolution included in the resolution data are equal, that is, when the resolution of the first image data meets the resolution requirement of the display screen of the terminal device, the display chip is used to use the first image data as the second image data. In other words, the display chip does not process the resolution of the first image data, and directly sends the first image data to the display screen through the bypass of the display chip, which can avoid the invalid work of the display chip and reduce the overall power consumption of the smart terminal.
