1. An image processing apparatus comprising: a noise amount prediction unit configured to predict a noise amount based on RAW image data acquired by image capturing under fixed image capturing conditions, a color adjustment parameter, which is information on color adjustment specified by a user, and the image capturing conditions; an image capturing condition determination unit configured to determine image capturing conditions the contents of which have been changed based on the predicted noise amount; a noise reduction parameter determination unit configured to determine a noise reduction parameter indicating the degree of noise reduction processing based on the image capturing conditions determined by the image capturing condition determination unit and the predicted noise amount; and a noise reduction unit configured to perform noise reduction processing in accordance with the noise reduction parameter for RAW image data acquired by image capturing under the image capturing conditions determined by the image capturing condition determination unit.
