The embodiment of the invention discloses an image processing method and device, a storage medium and electronic equipment. According to the embodiment of the invention, the shooting scene is exposedthrough the image sensor to obtain a first RAW image with a plurality of different exposure durations, the first RAW image comprises a plurality of pixel units, the plurality of pixel units are in one-to-one correspondence with the plurality of multi-stage photosensitive units, and each pixel unit comprises a plurality of pixel points with different exposure durations; a plurality of pixel pointswith different exposure durations are synthesized in each pixel unit in the first RAW image to obtain a second RAW image with a high dynamic range; and based on the second RAW image, the shooting scene is previewed or photographed or recorded, so that the shooting efficiency of the high-dynamic-range image is improved.
