Abstract:
An apparatus which adjusts exposure using luminance values of a plurality of blocks consisting of at least one pixel that constitute a photoelectrically converted image pickup screen, comprising:reference luminance value calculating means which calculates reference luminance values of the plurality of blocks; sorting means which sorts the plurality of blocks into blocks belonging to monochromatic light and blocks belonging to light other than the monochromatic light; luminance value setting means which sets higher values than the reference luminance values calculated by the reference luminance value calculating means as luminance values of the blocks belonging to the monochromatic light in the sorted plurality of blocks and sets the reference luminance values calculated by the reference luminance value calculating means as luminance values of the blocks belonging to the light other than the monochromatic light; and exposure adjusting means which adjusts exposure based on the set reference values.
