Abstract
Provided is an on-vehicle imaging device installed onboard a vehicle, and equipped with: an imaging unit for capturing an image of a subject, and having sensitivity to at least to the entire visible light spectrum of the red range (R), the green range (G), and the blue range (B), and to the infrared range (Cir); a signal processing unit for carrying out signal processing on video signals of at least a plurality of different bandwidths from a video image captured by the imaging unit; a pixel signal distribution processing unit for extracting pixel signal distribution information of one or more signals among video signals processed by the signal processing unit; a white balance processing unit for performing signal processing using a predetermined gain, so as to bring a video signal to a desired value; and a system control unit for performing control of the white balance processing unit and control of assessment area information for the purpose of extraction of pixel signal distribution information by the pixel signal distribution processing unit. In accordance with the pixel signal distribution information extracted by the pixel signal distribution processing unit, the system contro…
