Claim:
1. An image capturing apparatus performing exposure control comprising: an imager that converts a subject image into an image signal and output the image signal; a first evaluation value determination unit that determines a first evaluation value based on signals selected from R signals, G signals, and B signals of the image signal; a second evaluation value determination unit that determines a second evaluation value based on a luminance of the image signal; and an exposure control unit that calculates a control evaluation value for exposure control, using a weighted average of the first evaluation value and the second evaluation value, wherein the exposure control unit determines weights for the first evaluation value and the second evaluation value based on a correction amount for correcting the image signal output from the imager, and wherein the first evaluation value determination unit, the second evaluation value determination unit, and the exposure control unit are performed by at least one processor or circuit.
