The image processing method of the intelligent terminal provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Example one

Referring to fig. 1, fig. 1 provides a schematic diagram of a hardware structure of an image processing circuit of the present 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 first image data and resolution data according to data to be processed.

In an example, the main control chip 101 may be an Application Processor (AP) chip, which is hereinafter referred to as an AP side, where the AP side includes a Graphics Processing Unit (GPU) and a Display Processing Unit (DPU), and in an actual Application, the GPU draws image data with an original resolution according to a scene, and sends the image data to the DPU for data synthesis, and the DPU sends the synthesized image data with the original resolution to an independent Display chip, and meanwhile, the AP side may obtain a screen Display resolution of the smart terminal according to a system configuration of the smart terminal.

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

In this embodiment, since the purpose of the present invention 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 data processing amount of the main control chip in the aspect of image processing. That is, the first image data output by the main control chip has a smaller original resolution.

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

In this embodiment, the resolution data includes a target resolution of the first image data, which is a resolution of a 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 may directly send the first image data to the display chip 102, and the display chip 102 obtains the 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 an original resolution and a target resolution of the first image data, the original resolution is 720 × 1800, and the target resolution is 1080 × 1440, and then the resolution of the second image data output by the display chip is 1080 × 1440.

The image processing circuit provided by the embodiment comprises a main control chip and a display chip, wherein first image data and resolution data are output through the main control chip, second image data are output through the display chip on the basis of 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 through the display chip, the data processing amount of the main control chip can be greatly reduced, the working efficiency of the main control chip is improved, and the power consumption of terminal equipment is further reduced.

It can be known from the foregoing embodiment 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 the original resolution according to the first image data.

Thus, 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: scaling the first image data based on the original resolution and the target resolution, and outputting 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, the target resolution is 1080 × 1440, the display chip performs an enlargement process on the resolution of the first image data, and outputs the second image data with the resolution of 1080 × 1440.

In a case where the resolution data includes a target resolution of the first image data, the display chip is specifically configured to: acquiring the original resolution of the first image data according to the first image data; scaling the first image data based on the original resolution and the target resolution, and outputting 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, the display chip obtains the original resolution of the first image data by performing pixel analysis on the first image data, and the display chip performs amplification processing on the resolution of the first image data to output the second image data with the target resolution of 1080 × 1440. This way, the data processing amount of the main control chip can be further reduced.

In one scenario, when a low resolution image is directly zoomed on a high resolution screen, the detail part noise is too high due to the loss of information, so that the image becomes blurred. Therefore, in order to solve this problem, in this embodiment, before the display chip 102 performs the scaling process on the first image data, the display chip 102 is further configured to: and under the condition that the difference value between the original resolution and the target resolution is greater than a preset threshold value, performing super-resolution processing on the first image data. The super-resolution processing is carried out on the first image data, so that the detail information of the first image data can be supplemented, and the information loss is avoided.

In a practical example, the preset threshold may be set by a developer of the system, or may be set by a user in a customized manner, which is not limited herein. In this embodiment, the super-resolution processing is an enlargement of resolution, for example, a 512 × 512 picture is enlarged to a 1024 × 1024 picture.

In the embodiment, the display chip is used for performing the super-resolution processing optimization on the image data with the larger difference value between the resolution of the first image data and the target resolution, so that the image data with better display effect is further obtained.

In one scenario, the terminal device may have one display screen or a plurality of display screens, for example, when the display screen of the terminal device is a dual-screen display, image data and corresponding resolutions to be displayed by two different display screens may be different.

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

In this embodiment, the display chip 102 is specifically configured to: outputting 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 original resolution 1080 × 1440 and target resolution 720 × 1800, and the display chip performs reduction processing on the resolution of the first sub-image and outputs a third sub-image having the resolution of 720 × 1800.

In this embodiment, the display chip 102 is specifically configured to: outputting 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.

For example, the second sub-resolution data includes an original resolution 720 × 1080 and a target resolution 1500 × 2150, and the display chip performs an enlargement process on the resolution of the second sub-image and outputs a fourth sub-image having the target resolution 1500 × 2150.

The embodiment can perform different processing on the display data of different display screens of the same terminal, and has higher adaptability.

In one example, the content displayed by the 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 the video playing data, and the second display screen also currently displays the video playing data. The content displayed by 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, the first display screen currently displays video playing data, and the second display screen currently displays image data acquired by the shooting component. Therefore, the display chip can judge whether the contents of the first display screen and the second display screen are the same, and the processing of the first image data is performed in different scenes.

In this embodiment, under the condition that 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 configured to: outputting a third sub-image based on the target sub-image and the first sub-resolution data, and outputting a fourth sub-image based on the target sub-image and the second sub-resolution data, wherein the target sub-image comprises the first sub-image or the second sub-image.

That is, in the case where 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, and if the original resolution of the first sub-image is different from the original resolution of the second sub-image, an image with a higher original resolution in the first sub-image and the second sub-image is used as the target sub-image. For example, in the case where 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. The image with high original resolution is used as the target sub-image, so that more image information can be acquired, the output third sub-image and the output fourth sub-image are clearer, and a better display effect is achieved.

In this embodiment, under the condition that 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: the third sub-image is output based on the first sub-image and the first sub-resolution data, and the fourth sub-image is output based on the second sub-image and the second sub-resolution data. 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.

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, the resolution of the first image data meets the resolution requirement of the display screen of the terminal device, the display chip is configured to use 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, so that the invalid work of the display chip can be avoided, and the overall power consumption of the intelligent terminal is reduced.
