Abstract: This vehicle-mounted image recognition device achieves improved performance in flashing light source recognition at low cost and without loss of performance in image recognition applications such as preceding vehicle recognition and white line recognition. At staggered exposure timing, imaging is performed alternately with a first imaging unit and a second imaging unit, which form a pair in a vehicle-mounted camera. A flashing light source is detected from one or both of the first image obtained from the first imaging unit and a second image obtained from the second imaging unit, and the following times, exposure of the first imaging unit and the second imaging unit is matched to when the flashing light source is on. Thereby, flashing light sources are recognized with high accuracy without loss of performance of the image recognition function.
