Claim 22:
23. A non-transitory computer readable storage medium storing a program for causing a computer to perform an image processing method comprising the steps of:
applying development processing to an input RAW image;
storing a results image indicating results of the development processing;
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 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
updating the results image stored at the storage step by adding the acquired difference image, wherein
a processing load of the second development processing is higher than that of the first development processing.
