Image processing method and apparatus

An image processing apparatus, wherein the apparatus comprises:

• an obtaining unit, configured to obtain a video stream, wherein the video stream comprises a first frame of image, a second frame of image, and a third frame of image that are adjacent in time sequence;
• and
• a processing unit, configured to decode the video stream to obtain a first alignment frame, a second alignment frame, and at least one residual between the first frame of image, the second frame of image, and the third frame of image, wherein the first alignment frame is generated after the first frame of image moves a pixel block towards the second frame of image based on a first motion vector, the second alignment frame is generated after the third frame of image moves a pixel block towards the second frame of image based on a second motion vector, and the residual is a pixel difference between each macroblock in a previous frame of image and each macroblock in a subsequent frame of image after the previous frame of image performs motion compensation towards the subsequent frame of image based on a motion vector, wherein
• the processing unit is further configured to:
• generate at least one residual frame based on the at least one residual;
• and perform super resolution processing on the second frame of image based on the at least one residual frame, the first alignment frame, and the second alignment frame to obtain a second frame of image obtained after super resolution.

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

• and
• when the instructions are run, performs:
• obtaining a video stream, wherein the video stream comprises a first frame of image, a second frame of image, and a third frame of image that are adjacent in time sequence;
• decoding the video stream to obtain a first alignment frame, a second alignment frame, and at least one residual between the first frame of image, the second frame of image, and the third frame of image, wherein the first alignment frame is generated after the first frame of image moves a pixel block towards the second frame of image based on a first motion vector, the second alignment frame is generated after the third frame of image moves a pixel block towards the second frame of image based on a second motion vector, and the residual is a pixel difference between each macroblock in a previous frame of image and each macroblock in a subsequent frame of image after the previous frame of image performs motion compensation towards the subsequent frame of image based on a motion vector;
• generating at least one residual frame based on the at least one residual;
• and
• performing super resolution processing on the second frame of image based on the at least one residual frame, the first alignment frame, and the second alignment frame to obtain a second frame of image obtained after super resolution.
