Abstract:
1. An image display system provided on a vehicle, comprising: a first image taking device which takes both a right side-rear view image of a first area along the right side and to the rear of the vehicle and a rear view image of a second area to the rear of the vehicle, or at least the right side-rear view image; a second image taking device which takes both a left side-rear view image of a third area along the left side and to the rear of the vehicle and the rear view image of the second area, or at least the left side-rear view image; a first running condition computing unit which performs image processing on data of the images taken by the first and second image taking devices, and which thereby detects a road lane in which the vehicle is running, to compute a running condition of the vehicle indicating whether the vehicle is making a lane change, wherein the first running condition computing unit sets a right threshold line at the right side of the road lane and a left threshold line at the left side of the road lane, the right and left threshold lines being positioned relative to the road lane; a second running condition computing unit which performs image processing on data of the images taken by the first and second image taking devices, to compute a running condition of an obstacle in the first area or in the second area or in the third area; a display start judgment unit which determines a first display start time point to start displaying the right side-rear view image and a second display start time point to start displaying the left side-rear view image based on the running conditions of the vehicle and the obstacle computed by the first and second running condition computing units, wherein the display start judgment unit determines the first display start time point as being a time point at which a first point in a defined region of the obstacle in the images processed by the second running condition computing unit passes the right threshold line and determines the second display start time point as being a time point at which a second point in the defined region of the obstacle passes the left threshold line; and a presenting device which starts displaying the right side-rear view image at the first display start time point and starts displaying the left side-rear view image at the second display start time point.
