Targeted super-resolution image processing method and apparatus, and electronic device

An image processing apparatus, comprising a memory and a processor, wherein the memory is configured to store a computer program, and the processor is configured to invoke the computer program from the memory and run the computer program to perform an image processing method, the method comprising:

• obtaining an inter-frame residual between a first image and a previous image frame adjacent to the first image to obtain a residual block, wherein the residual block comprises a plurality of residual points that are in a one-to-one correspondence with locations of a plurality of pixels in the first image, and each residual point has one residual value;
• determining a first target pixel region in the first image based on the residual block;
• performing super-resolution processing on the first target pixel region in the first image to obtain a second target pixel region after the super-resolution processing;
• and
• updating a first pixel region in the first image by using a second pixel region that is in the previous image frame and that is obtained after super-resolution processing, wherein the first pixel region comprises a pixel region in the first image other than the first target pixel region, and
• the first image obtained after super-resolution processing comprises the second target pixel region obtained after the super-resolution processing and the updated first pixel region.

An electronic device, comprising a processor and a memory, wherein

• the memory is configured to store a computer program;
• and
• when the processor executes the computer program stored in the memory, causes the processor to perform an image processing method comprising:
• obtaining an inter-frame residual between a first image and a previous image frame adjacent to the first image to obtain a residual block, wherein the residual block comprises a plurality of residual points that are in a one-to-one correspondence with locations of a plurality of pixels in the first image, and each residual point has one residual value;
• determining a first target pixel region in the first image based on the residual block;
• performing super-resolution processing on the first target pixel region in the first image to obtain a second target pixel region after the super-resolution processing;
• and
• updating a first pixel region in the first image by using a second pixel region that is in the previous image frame and that is obtained after super-resolution processing, wherein the first pixel region comprises a pixel region in the first image other than the first target pixel region, and
• the first image obtained after super-resolution processing comprises the second target pixel region obtained after the super-resolution processing and the updated first pixel region.
