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.
