摘要： An image processing apparatus includes a controller that determines a light color of a traffic light from a camera image. The controller is configured to: (i) perform image recognition of the camera image to identify a signal region in which the traffic light exists in the camera image; (ii) set a plurality of different spatial intervals between detectors that detect pixels in the signal region having respective color components of respective lights included in the traffic light; (iii) generate a plurality of feature maps indicating a feature amount for an arrangement pattern of each of the respective color components based on detections of the signal region by the detectors using the plurality of different spatial intervals; and (iv) determine the light color of the traffic light based on the plurality of feature maps.
