Abstract
Based on an image captured by an onboard camera, an arrow signal detector sets an arrow signal area on the basis of a signal light distance between a lit red signal light of a traffic light and a vehicle equipped with the arrow signal recognition device, counts the number of color tone effective pixels assumed as being lit within each arrow signal area, further searches for and counts color tone ineffective pixels in the color tone effective pixels on the basis of pixel information on the vicinity of each color tone effective pixel, and calculates an arrow effective pixel number from the difference between the number of color tone effective pixels and the number of color tone ineffective pixels.
