Abstract
An imaging device includes a histogram unit that extracts luminance information from video signals obtained by image capture and generates a histogram, a white balance detector unit that detects the deviation in the white balance of the video signal, and a white balance processor unit that corrects the white balance of the video signal; and along with selecting the imaging conditions of the imaging unit based on the deviations detected by the white balance detector unit, also controls the white balance processor unit. When there is a large deviation in the white balance, the imaging device decides whether or not to correct the white balance according for example to the hue.
