Abstract: In a vehicle-mounted camera system, an appropriate white balance correction processing according to a situation is executed to a long exposure time image and a short exposure time image shot in variously changing illumination environments. A vehicle-mounted camera system includes a vehicle-mounted camera that performs relatively long exposure time shooting and short exposure time shooting, a signal processing device (signal processing device) that executes a white balance correction processing for each of a long exposure time image and a short exposure time image, composes these images after the white balance correction processing, and generates a high dynamic range image, and a system control part (processing switch device) that obtains an illumination environment in which the vehicle is placed, and switches the white balance correction processing for the long exposure time image and the white balance correction processing for the short exposure time image according to the illumination environment.

Abstract: To obtain a color signal having a wide dynamic range (i.e., high sensitivity) and color reproducibility similar to human vision characteristics regardless of the amount of the near infrared components contained in light captured by an imaging device. The imaging device is configured to receive light which has transmitted through the filters selectively transmit light having different wavelengths from each other, to generate an output signal RAW0 by converting the received light using the image pickup element 102 having the plurality of pixels, and to remove, by a removal rate E (Rr) determined in accordance with the ratio Rr of near infrared light component calculated for each pixel, the near infrared light component for each pixel from the generated output signal RAW0, to thereby generate an infrared-separated signal (Ra, Ga, Ba).
