White balance adjustment method, image sensing apparatus, program, and storage medium

摘要

An object of this invention is to always obtain accurate white balance regardless of photographing conditions. To achieve this object, a white balance adjustment method includes a first color temperature calculation step of calculating a first color temperature from an image signal within a white detection range out of image signals from an image sensing element, a second color temperature calculation step of calculating a second color temperature from an image signal within a chromatic color detection range out of image signals from the image sensing element, and a white balance adjustment step of adjusting white balance on the basis of the first and second color temperatures.
