Example 1

Referring to FIG. 1 , FIG. 1 provides a schematic diagram of the hardware structure of an image processing circuit in this embodiment, 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 .

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

In one example, the main control chip 101 may be an application processor (Application processor, AP) chip hereinafter referred to as the AP side, and the AP side has a graphics processing unit (graphics processing unit, GPU) and a display processing unit (Display Processor Unit, DPU) ), in practical applications, the GPU will draw the original resolution image data according to the scene, and send it to the DPU for data synthesis, and the DPU will deliver the synthesized image data with the original resolution to the independent display chip. The screen display resolution of the smart terminal is obtained according to the system configuration of the smart terminal.

In one example, the data to be processed may be scene information obtained by the AP through the camera module of the terminal device, or video data obtained from the cloud or local storage. The first image data may be image data synthesized by the DPU according to the image data drawn by the GPU.

Among them, since the purpose of this embodiment is to reduce the data processing amount of the processor in the terminal device and improve the 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 The data processing volume of the main control chip in image processing. That is to say, the first image data output by the main control chip has a smaller original resolution.

In an example, since the resolutions of the display screens of different terminal devices may be different, the resolutions of multiple display screens of the same terminal device may also be different. Therefore, the main control chip can obtain the system configuration information of the terminal device to Obtain the resolution data of the display screen corresponding to the terminal device. Therefore, by processing the first image data, the output image resolution can be adapted to the display screen of the terminal device.

In this embodiment, the resolution data includes the target resolution of the first image data, and the target resolution 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.

In this embodiment, the display chip 102 is configured to output the 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.

For example, the resolution data includes the original resolution and 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.

The image processing circuit provided by this embodiment includes a main control chip and a display chip. The main control chip outputs first image data and resolution data, and the display chip outputs a second image based on the first image data and resolution data. The resolution of the second image data is determined based on the resolution data, and the resolution processing process of the first image data is completed by the display chip, which can greatly reduce the data processing volume of the main control chip and improve the work efficiency of the main control chip. , thereby reducing the power consumption of the terminal device.

It can be known 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 may obtain its original resolution according to the first image data. Rate.

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 configured to: scale the first image data based on the original resolution and the target resolution, and output the second image data. 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 amplifies the resolution of the first image data, and the output resolution is the second one with the target resolution of 1080*1440. image data, in this way, the second image data can be obtained more quickly.

When the resolution data includes the target resolution of the first image data, the display chip is specifically configured to: obtain the original resolution of the first image data according to the first image data; The image data is scaled to output 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 the original resolution of the first image data as 720*1800. The resolution is enlarged, and the output resolution is 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.

In a scene, when a low-resolution image is directly scaled to a high-resolution screen, the noise in the details is too high due to the loss of information, 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 for: when the difference between the original resolution and the target resolution is greater than a preset threshold Next, perform super-score processing on the first image data.

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

In a 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 resolution Rates can vary.

At this time, the first image data includes the first sub-image and the second sub-image, the resolution data includes the first sub-resolution data and the second sub-resolution data, and the first sub-resolution data is the resolution corresponding to the first sub-image. 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.

For example, the second sub-resolution data includes the original resolution of 720*1080 and the target resolution of 1500*2150. The display chip performs enlarging processing on the resolution of the second sub-image, and the output resolution is the fourth resolution of the target resolution of 1500*2150. subimage.

In one example, the content displayed on multiple display screens of the 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 also Displays video playback data. The content displayed on the multiple display screens of the terminal device may also be different. For example, the terminal device includes a first display screen and a second display screen.

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 may 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 and the original resolution of the second sub-image are different, the original resolution of the two is used. The higher image 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 of 1080*1440 is greater than the resolution of 720*1800, it is determined that the first sub-image is The sub-image is the target sub-image. By using the image with high 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, and thus have a better display effect.

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 Sub-image, outputting a fourth sub-image based on the second sub-image and the second sub-resolution data. The third sub-image may be displayed on the first display screen, and the fourth sub-image may be displayed on the second display screen.

It should be noted that, in this embodiment, when the original resolution included in the resolution data is equal to the target resolution, that is, when the resolution of the first image data meets the resolution requirement of the display screen of the terminal device, the display The chip is used for taking the first image data as the second image data. That is to say, 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 operation of the display chip and reduce the overall power consumption of the smart terminal. .

The third processing unit 1024 is configured 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 the original resolution of 1080*1440 and the target resolution of 720*1800, the third processing unit 1024 performs downscaling processing on the resolution of the first sub-image, and the output resolution is the target resolution of 720*1800 the third subimage.

The fourth processing unit 1025 is configured 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.

By using the image with high 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, and thus have a better display effect.

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 first sub-image based on the first sub-image and the first sub-resolution data Three sub images. The fourth processing unit is specifically configured to: output a fourth sub-image based on the second sub-image and the second sub-resolution data.
