Imaging device with brightness correction

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, when the one of the brightness signals having undergone level adjustment already reached a given level which is lower than a saturation level of the brightness detection photoelectric conversion elements and when level(s) of composite signal(s) corresponding to one(s) of the color detection photoelectric conversion elements located around the one of the brightness detection photoelectric conversion elements are higher than the given level, the brightness signal correction section performs correcting operation for replacing the one of the brightness signals having a level equal to or higher than the given level with a signal in which the one of the brightness signals and composite signal(s) having level(s) greater than the given level are combined.
