Abstract
An image area including a traffic light in an image taken by a camera is determined, and the determined image area including the traffic light is extracted and the extracted image area is subjected to enlargement processing to determine whether a status of the traffic light is red or green, and notice to start crossing is provided to a user under a condition that the status of the traffic light switches from red to green. Consequently, even with image information from a single camera alone, accuracy in recognition of the traffic light can sufficiently be enhanced. As a result, crossing start notice can properly be provided without an increase in configuration complexity and weight of the system.
