Vehicle rearview back-up system and method
First Claim
1. A vehicle rearview back-up system for providing a rear view for a driver, the vehicle rearview back-up system comprising:
- a backup camera disposed at a rear of the vehicle for capturing an image of a parking spot in which the vehicle is to be parked when the vehicle is backed-up to a predetermined position;
a display capable of being touched by the driver to outline the parking spot on the captured image of the parking spot to obtain an outlined parking spot;
a calculator for calculating an imaging ratio between a size of the captured image of the parking spot and a size of the outlined parking spot;
a storage unit for storing a vehicle image;
the display further simultaneously displaying the vehicle image and the outlined parking spot on the captured image of the parking spot according to the calculated imaging ratio;
a detector for detecting moving direction and moving distance of the vehicle; and
a moving unit for moving the vehicle image in the the captured image of the parking spot according to the detected moving direction and moving distance of the vehicle, and the calculated imaging ratio for implementing the back-up process of the vehicle.

Abstract
A vehicle rearview back-up system includes a backup camera, a display, a calculator, a storage unit, a detector, and a moving unit. The backup camera captures an image of a parking spot when the vehicle is backed-up to a predetermined position. The display displays the captured image and an outlined parking spot in the captured image defined by the driver. The calculator calculates an imaging ratio between the size of the captured image and the size of the outlined parking spot. The display displays a vehicle image in a predetermined region according to the calculated imaging ratio. The detector detects moving direction and moving distance of the vehicle. The moving unit moves the vehicle image in the display according to the moving direction and moving distance of the vehicle, and the calculated imaging ratio for implementing the back-up process of the vehicle.
