Abstract
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.
