Patent ID: 8274585

Claim:
An imaging device comprising: an imaging element that comprises (i) at least three types of color detection photoelectric conversion elements that detect different color components of light and (ii) brightness detection photoelectric conversion elements that detect brightness components of light; a level adjustment section that adjust levels of color signals acquired respectively from at least said three types of color detection photoelectric conversion elements and levels of brightness signals acquired from the brightness detection photoelectric conversion elements; a composite signal generation section that generates, from ones of the color signals undergone level adjustment, at least three different color signals in correspondence with each of the color detection photoelectric conversion elements and subjects at least said three color signals to weighting and addition, so as to generate composite signals respectively corresponding to the color detection photoelectric conversion elements; and a brightness signal correction section that corrects one of the brightness signals having undergone level adjustment, through use of corresponding one(s) of the composite signals, wherein the color detection photoelectric conversion elements are arranged in a Bayer pattern, and wherein the brightness signal correction section combines a high-frequency component of the one of the brightness signals having undergone level adjustment with a low-frequency component of the composite signal(s) corresponding to one(s) of the color detection photoelectric conversion elements located around one of the brightness detection photoelectric conversion elements generating the one of the brightness signals, so as to acquire signals as the corrected brightness signals.
