Image processing apparatus, imaging apparatus, and image processing method

An imaging apparatus comprising:

• an optical system that makes reduction in resolution uniform in a predetermined range on an optical axis;
• an imaging unit;
• and
• an image processing apparatus, wherein
• the 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, for the third pixel.

An image processing method comprising:

• performing white balance processing 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 color and thereby generates a second pixel;
• performing value adjustment processing 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 out of the second pixel;
• and
• performing restoration processing that restores, by a restoration filter, resolution that has been reduced due to an optical system, on the third pixels.
