Image processing method and device, electronic equipment, and storage medium

An electronic device, comprising:

• an image sensor;
• a processor;
• and
• a memory, configured to store executable instructions of the processor;
• wherein the processor is configured to execute the executable instructions on an image acquired by the image sensor to:
• acquire a first image and a second image, wherein a resolution of the second image is greater than a resolution of the first image;
• determine difference information between a target pixel in the second image and a reference pixel in the first image corresponding to the target pixel;
• and
• acquire a target image with the same resolution as the second image by applying an image differencing process to a predetermined image with the same resolution as the first image based on the difference information.

A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor, cause the processor to:

• acquire a first image and a second image, wherein a resolution of the second image is greater than a resolution of the first image;
• determine difference information between a target pixel in the second image and a reference pixel in the first image corresponding to the target pixel;
• and
• acquire a target image with the same resolution as the second image by applying an image differencing process to a predetermined image with the same resolution as the first image based on the difference information.
