Patent ID: 8692910

Claim:
An image processing device comprising: a judgment unit that judges to which group a pixel of a color image belongs in accordance with a position of the pixel, the group being a group among a plurality of separate groups determined in accordance with an arrangement of color filters adjacent to a color filter of the pixel, and the color image being an image generated based on output signals from an image acquisition element having the color filters in predetermined arrays; a storage unit in which the plurality of separate groups are individually stored in association with correction matrices; and a correction unit that (i) obtains, from the storage unit, a correction matrix corresponding to the group to which the pixel belongs, and (ii) corrects types of image signals targeted for correction by using the obtained correction matrix and all types of image signals in the pixel; wherein, when individual pixels of color images obtained by capturing images of a plurality of color charts having different spectral characteristics are divided into the groups, the correction matrices comprise correction matrices that define relationships between at least one type of image signal value in a first group and all types of image signal values in a second group.
