Abstract:
1. An image processing apparatus for performing a white balance correction for RAW data obtained by an image capturing unit, comprising: a storage, operable to store a RAW file to which the RAW data and developed data obtained by performing a development processing to the RAW data are attached; and a corrector, operable to perform the white balance correction for the RAW data based on the developed data stored in the storage, wherein the corrector performs a correction processing to a relationship between a gradation level and an appearance frequency in the RAW data in such a manner that a shape of a histogram representing the relationship between the gradation level and the appearance frequency in the RAW data is coincident with that of a histogram representing a relationship between a gradation level and an appearance frequency in the developed data, thereby performing the white balance correction for the RAW data for each color information.
