Image processing method and apparatus, and electronic device

An image processing apparatus, applied in an electronic device, wherein the electronic device comprises a display and an imaging apparatus comprising 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:
• a control module, configured to control the image sensor to output a merged image and a color-block image of a same scene, wherein the merged image comprises an array of merged pixels, 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;
• a first converting module, configured to convert the merged image into a merged true-color image;
• a second converting module, configured to convert the color-block image into a simulation true-color image;
• a displaying module, configured to display the merged true-color image and the simulation true-color image;
• and
• a storing module, configured to store at least one of the merged true-color image and the simulation true-color image according to a user input.
