An imaging environment that greatly affects image recognition accuracy is recognized for applications in onboard systems of various sorts including imaging devices. An imaging device for imaging areas around the vehicle is mounted on a vehicle. Before executing image recognition processing, information is acquired on objects and texture, such as traffic signs and pedestrian crossings, present within a field of view of the imaging device.
