发明名称 Image processing apparatus, imaging apparatus, and image processing method
摘要 An image processing apparatus comprises: a white-balance processing unit that multiplies a first pixel that includes a plurality of colors constituting a pickup image that is picked up by an imaging unit by a gain value according to the colors and thereby generates a second pixel; a value adjusting unit that generates a third pixel by maintaining the second pixel that is equal to or smaller than a predetermined value out of the second pixel as it is, and by replacing, with the predetermined value, the second value that is larger than the predetermined value out of the second pixel; and a restoration processing unit that restores, by a restoration filter, resolution that has been reduced due to an optical system, on the third pixel.
