Description

The present invention relates to a rear blind spot confirmation device. In particular, the present invention relates to the structure of a rear blind spot confirmation device for confirming the presence of a predetermined blind spot from images captured by a back-eye camera attached to a truck or the like.

In a passenger car or the like, the sides and rear of the vehicle can be viewed through the side mirrors and rear window. Furthermore, a technique has been disclosed in which a Fresnel lens is attached to the rear window of a passenger car so that it can appear and retract, thereby reducing blind spots when the vehicle is backing up (for example, see Patent Document 1).
