Patent ID: 8310571

Claim:
An image processing device that performs a color shading correction for a plurality of pixel signals output from an imaging sensor with a color separator, the imaging sensor capturing a subject via an optical system and outputting the pixel signals forming an image and being influenced by the color shading depending on optical characteristics of the optical system and optical characteristics of the color separator, the image processing device comprising: a data obtaining unit that obtains a first image having a color distribution that is known in advance; a decision making unit that decides whether or not the color distribution of the first image obtained by the data obtaining unit is uniform; a correction data obtaining unit that obtains correction data by using the first image if the color distribution is decided to be uniform, and that obtains the plurality of correction data by using the first image and color distribution data regarding the first image if the color distribution is decided not to be uniform; a correction execution decision unit that decides that the color shading correction is to be executed for the pixel signals in a peripheral area of a second image and decides that the color shading correction is not to be executed for the pixel signals in a respectively central area of the second image; and a correction unit that corrects each color component of the plurality of pixel signals of the second image for which the color shading correction is decided to be executed by the color shading correction execution decision unit, by using the correction data obtained by the correction data obtaining unit.
