Digital camera and white balance adjustment method

Abstract

A digital camera capable of performing more stable white balance adjustment is provided. In a digital camera for adjusting white balance of a video signal corresponding to an object and supplied from an image sensor, a white balance adjustment circuit 34 changes at least some of a plurality of light source regions predefined on a color difference plane based on a result of detection of flicker in a light source illuminating the object performed by a flicker detection circuit 70. The white balance adjustment circuit 34 then checks which of the plurality of light source regions containing the changed region includes the color difference component of the video signal, thereby estimating the light source of the object, and adjusting white balance in accordance with the estimation result.
