Classification: CPC G  H | IPC G

Claim 14:
15. An image processing apparatus comprising:
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 store the stored results image in association with the acquired difference image or update the stored results image by the acquired difference image.
