Image processing method and apparatus, electronic device, program, and readable storage medium

An image processing apparatus, comprising:

• a processor and a memory, the processor and the memory being interconnected, wherein the memory is configured to store a computer program;
• and the processor is configured to perform:
• acquiring an image size of an image and original image data of the image, a color encoding format corresponding to the original image data being a source encoding format;
• creating a first texture storage area according to the image size, and storing image data of the image into the first texture storage area;
• creating, according to the image size and a target encoding format, a second texture storage area for storing target image data to be generated, a color encoding format corresponding to the target image data being the target encoding format;
• and
• performing, through a shader called by a graphics processor (GPU), encoding format conversion on the original image data stored in the first texture storage area to generate the target image data corresponding to each texture coordinate in the second texture storage area, and storing the target image data corresponding to each texture coordinate into a corresponding storage location in the second texture storage area, comprising, for a texture coordinate in the second texture storage area:
• determining, through the shader called by the GPU, a first storage location corresponding to the texture coordinate in the second texture storage area;
• determining, according to a storage location correspondence between the first texture storage area and the second texture storage area, a second storage location corresponding to the texture coordinate in the first texture storage area;
• and
• computing, according to the original image data corresponding to the second storage location, the target image data corresponding to the texture coordinate in the second texture storage area, and storing the target image data into the first storage location.

A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores a computer program;

• and the computer program is executed by a processor to implement:
• acquiring an image size of an image and original image data of the image, a color encoding format corresponding to the original image data being a source encoding format;
• creating a first texture storage area according to the image size, and storing image data of the image into the first texture storage area;
• creating, according to the image size and a target encoding format, a second texture storage area for storing target image data to be generated, a color encoding format corresponding to the target image data being the target encoding format;
• and
• performing, through a shader called by a graphics processor (GPU), encoding format conversion on the original image data stored in the first texture storage area to generate the target image data corresponding to each texture coordinate in the second texture storage area, and storing the target image data corresponding to each texture coordinate into a corresponding storage location in the second texture storage area, comprising, for a texture coordinate in the second texture storage area:
• determining, through the shader called by the GPU, a first storage location corresponding to the texture coordinate in the second texture storage area;
• determining, according to a storage location correspondence between the first texture storage area and the second texture storage area, a second storage location corresponding to the texture coordinate in the first texture storage area;
• and
• computing, according to the original image data corresponding to the second storage location, the target image data corresponding to the texture coordinate in the second texture storage area, and storing the target image data into the first storage location.
