IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND MEDIUM

摘要

An object of the present invention is to provide an image processing apparatus capable of reducing noise in advance that occurs due to color adjustment. The present invention is an image processing apparatus having: 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 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; 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.
