First Claim
Patent Images
1. An apparatus for watching around a vehicle, the apparatus mounted thereon, the apparatus comprising:
- an image pick-up unit, having a reflective portion and an imaging portion, for picking up an image to a left side and a right side at the front of the vehicle, the image pick-up unit fitted to an opening of a grille formed outside a vehicular radiator with respect to a vehicle operator, only the reflective portion of the image pick-up unit extending beyond the grille, reflective surfaces of the reflective portion disposed in parallel to a vertical direction of the vehicle and the imaging portion taking in the image reflected by the reflective portion;
a display unit for displaying the image, the display unit provided in the vehicle;
a control unit for processing the image to enable the vehicle operator to control the movement of the vehicle based on the displayed image; and
a warning unit coupled to the control unit and transmitting a warning signal to a user of another vehicle, wherein an image optical axis of the imaging portion is set so that incident optical axes of the image tilt vertically and obliquely with respect to a horizontal plane when the image reflected in the reflective portion are introduced into the imaging portion and the imaging portion picks up the image in respective image pick-up directions which are obliquely above or below the horizontal plane.

Abstract
A prism for reflecting rays of light 17L and 17R incident from left and right image pick-up directions on the rear side of the direction of travel A is disposed in parallel to the vertical direction of a vehicle. The image pick-up optical axis of an image pick-up unit 15 is set to tilt vertically and obliquely with respect to a horizontal plane C, whereby the images in the respective image pick-up directions which are obliquely above or below the horizontal plane are picked up by the image pick-up unit 15.
