Abstract
An image processing device that uses YC-raw data as a development processing target includes an image processing unit that performs conversion processing, into an image sensor output format, on YC-raw data that is image data obtained by performing pre-white balance processing, demosaicing, and a YC conversion processing on image data in the image sensor output format, and further performs reverse pre-white balance processing with respect to the pre-white balance processing and remosaicing to restore a state prior to the demosaicing.
