Classification: CPC G  H | IPC G

Claim 17:
18. An image processing system that develops a RAW image, comprising:
a first apparatus and a second apparatus, wherein
the first apparatus comprises:
a development unit configured to apply development processing to an input RAW image;
a storage unit configured to store a results image indicating results of the development processing;
an acquisition unit configured to acquire 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
an updating unit configured to update the results image stored in the storage unit based on the difference image, and

the second apparatus comprises:
an acquisition unit configured to acquire a RAW image from the first apparatus;
a development unit configured to apply the first development processing and the second development processing to the acquired RAW image;
a generation unit configured to generate 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
a transmission unit configured to transmit the generated difference image to the first apparatus.
