Imaging using normalized luminance value to display focus state

Abstract

Provided is an imaging apparatus including an imaging unit that performs imaging with an image sensor having pixels of first, second, and third colors, a luminance ratio calculation unit that integrates luminance of each of the first, second, and third colors within a focus determination region of an imaging signal output by the imaging unit and calculates a ratio of the luminance between the integrated values of the colors, a luminance normalization unit that normalizes the integrated value of the luminance of the first color within the focus determination region of the imaging signal output by the imaging unit at the ratio of the luminance between the integrated values calculated by the luminance ratio calculation unit, and a display processing unit that performs display corresponding to the integrated value of the luminance normalized by the luminance normalization unit.
