Claim 21:
22. A control method of an image processing system that develops a RAW image and which includes a first apparatus and a second apparatus, wherein
the first apparatus is controlled so as to perform 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 based on the difference image, the second apparatus is controlled so as to perform the steps of:
acquiring a RAW image from the first apparatus;
applying the first development processing and the second development processing to the acquired RAW image;
generating a difference image indicating a difference between a first results image obtained by applying the first development processing and a second results image obtained by applying the second development processing; and
transmit the generated difference image to the first apparatus, and

a processing load of the second development processing is higher than that of the first development processing.
