Image processing method and apparatus, and electronic device

An image processing apparatus, applied in an electronic device, wherein the electronic device comprises an image sensor, the image sensor comprises an array of photosensitive pixel units and an array of filter units arranged on the array of photosensitive pixel units, each filter unit corresponds to one photosensitive pixel unit, and each photosensitive pixel unit comprises a plurality of photosensitive pixels, the image processing apparatus comprises a non-transitory computer-readable medium comprising computer-executable instructions stored thereon, and an instruction execution system which is configured by the instructions to implement at least one of:

• an output module, configured to output a merged image and a color-block image by the image sensor in a same scene, wherein, the merged image comprises an array of merged pixels, and the photosensitive pixels in a same photosensitive pixel unit are collectively output as one merged pixel, the color-block image comprises image pixel units arranged in a preset array, each image pixel unit comprises a plurality of original pixels, each photosensitive pixel unit corresponds to one image pixel unit, and each photosensitive pixel corresponds to one original pixel;
• an identifying module, configured to identify a preset target region in the merged image;
• a first converting module, configured to convert a part of the color-block image corresponding to a part of the merged image beyond the preset target region into a first image using a first interpolation algorithm, wherein, the first image comprises first simulation pixels arranged in an array, and each photosensitive pixel corresponds to one first simulation pixel;
• a second converting module, configured to convert a part of the merged image within the preset target region into a second image using a second interpolation algorithm, wherein, the second image comprises second simulation pixels arranged in an array, and each photosensitive pixel corresponds to one second simulation pixel, and a complexity of the second interpolation algorithm is less than that of the first interpolation algorithm;
