SIGN INFORMATION OUTPUT APPARATUS

摘要

A sign information output apparatus includes an output instructor for instructing an information output section to stop output of sign information if a traveled distance measured in response to the detection of a sign exceeds a threshold value, and a threshold value changer for changing a threshold value depending on at least one of interval information with respect to an interval at which signs of one type are placed, speed limit information with respect to a speed limit of the road, and a speed of the vehicle.

1. A sign information output apparatus comprising:
an image capturing unit mounted on a vehicle configured to capture an image and acquire a captured image signal representing the captured image while the vehicle is being driven; a sign detector configured to detect a sign on a peripheral edge of a road from an image area represented by the captured image signal acquired by the image capturing unit; an information output section configured to output sign information with respect to a type of the sign that is detected by the sign detector; a traveled distance measurer configured to measure a traveled distance over which the vehicle has traveled, in response to detection of the sign; an output instructor configured to instruct the information output section to stop output of the sign information if the traveled distance measured by the traveled distance measurer exceeds a threshold value; and a threshold value changer configured to change the threshold value depending on at least one of interval information with respect to an interval at which signs of one type are placed, speed limit information with respect to a speed limit of the road, and a speed of the vehicle.
