ABSTRACT:
A motor vehicle peripheral monitoring apparatus uses a monitor region extension member as optical image forming means. The monitor region extension member comprises an upper image passage part and an upper image compression part. The upper image passage part includes a prism structural element of substantially a semi-conical shape whose prism apical angles become the maximum angle at the center of the member and are decreased toward the extremity from the center of the member. The upper image compression part includes a cylindrical structural element having a curved surface whose angles are set to be smaller continuously from the prism apical angles of the upper image passage part.
