Abstract
An in-vehicle imaging device is provided with a detection region setting unit for setting a detection region, which corresponds to a predetermined object to be detected within an imaging screen; a color signal determination unit for setting a specific color corresponding to the object to be detected, and for determining whether the color data of pixels contained in the detection region are close to the specific color; and a gain control unit for averaging the color data of pixels (approximate color pixels) that were determined to be close to the specific color within the detection region and for adjusting the color gain of the image signal on the basis of a differential value of the color data of the specific color and the average value of the color data of the approximate color pixels.
