ABSTRACT:
The photosensitive portion of an image sensor which is used for monitoring a forward view of a vehicle on a roadway is formed that is horizontally elongated with an aspect ratio in a range from 1:1.8 to 1:3.1 adjustable in correspondence with the design speed of the roadway, the minimum radius of curvature R, the maximum longitudinal slope S of the roadway, the braking distance D of the vehicle, and the number of lanes to be imaged. Here, the aspect ratio of the photosensitive portion is set at a ratio within a range from 1:1.8 to 1:3.1 in correspondence with the conditions of the design speed of the roadway and of the number of lanes to be imaged including the lane in which the vehicle is driving.
