Classification: CPC G  H | IPC G

Claim 18:
19. An image processing method comprising the steps of:
applying development processing to an input RAW image;
acquiring a difference image indicating a difference between a first results image obtained by applying first development processing the same as the development processing to the RAW image and a second results image obtained by applying second development processing different from the first development processing to the RAW image,
wherein the development processing includes at least demosaic processing, demosaic processing in the first development processing is processing to estimate information on a color component that does not exist in a pixel of interest by an interpolation method, and demosaic processing in the second development processing is processing that uses a trained neural network; and
generating a third results image by applying development processing to the input RAW image based on the first results image and the difference image, wherein
a processing load of the second development processing is higher than that of the first development processing.
