Description

Image processing method, readable storage medium, and electronic apparatus Technical Field The present application relates to the field of image processing technologies, and in particular, to an image processing method, a readable storage medium, and an electronic device. Background The processing of each composite image to be displayed by the electronic device typically includes rendering, compositing, and post-processing (optional). Wherein, drawing means generating image data of each layer of the composite image, rendering means rendering the layer data of each layer into a layer, compositing means laminating each layer into a composite image, post-processing means performing image quality enhancement processing such as super resolution, super frame, contrast/sharpness adjustment, and the like on the composite image. To avoid a screen displayed by the electronic device from being stuck, the value of the frame rate of the composite image synthesized by the electronic device is typically greater than or equal to the value of the refresh rate of the display screen of the electronic device. But electronic devices implement rendering, as well as rendering, compositing, and post-processing processes-image processing-consume significant power. Disclosure of Invention In view of the above, the present application provides an image processing method, a readable storage medium, and an electronic device, which are advantageous for reducing power consumption of the electronic device for image processing. The image processing method is applied to electronic equipment and comprises the steps of synthesizing part of image layers in P image layers through the first processor to obtain Q first images, wherein the synthesis frequency of the first processor is a first numerical value, P is an integer larger than 2, Q is an integer larger than 1 and P is larger than or equal to Q, the Q first images are transmitted to the second processor through the first processor, the number of image frames transmitted to the second processor in unit time of the first processor is a second numerical value, the second numerical value is larger than the first numerical value, and the second images are displayed based on the Q first images. In the method, the electronic device synthesizes at least part of the P layers corresponding to the user interface to be displayed through the first processor to obtain Q first images and sends the Q first images to the second processor. The electronic device then displays, via the second processor, a second image based on the Q first images. In this way, since the power consumption of the second processor to generate the second image based on the Q first images is low, the overall power consumption of the electronic device to generate the second image can be reduced. In addition, since the data size of the Q image layers is larger than the data size that can be accommodated by one image frame, the first processor may transmit the Q first images to the second processor in a period (inverse of the first value) corresponding to the synthesis frequency by transmitting a plurality of (second value) image frames in a unit time, so that the second processor may generate and display the second image based on the Q first images in time. In some implementations, in the process of processing the layers of the user interface to be displayed, P and Q may be equal for some user interfaces to be displayed (i.e., the first processor only needs to render to obtain P layers without synthesizing the P layers, where the P layers obtained by rendering are Q first images), and P may be greater than Q for another portion of the user interface to be displayed (i.e., the first processor needs to render to obtain P layers first and then synthesize some of the P layers to obtain Q first images). In one possible implementation of the first aspect, the displaying the second image based on the Q first images includes performing rendering processing on the first images by a second processor, synthesizing the Q first images after the rendering processing by the second processor to obtain the second image, and displaying the second image. In one possible implementation of the first aspect, the rendering process includes at least one of super-resolution processing, contrast adjustment, image sharpening processing, super-frame processing, detail enhancement processing, high dynamic range processing, image noise reduction processing, blurring processing, and generating an animated image of an attribute animation. In this implementation, since the power consumption of the second processor for performing the rendering process is low, the overall power consumption of the electronic device for obtaining the second image based on the P layers can be reduced by performing the rendering process on the first image by the second processor. In a possible implementation of the first aspect, displaying the second image based on the Q first images inc
