Abstract

Disclosed is a rear-view camera system for a vehicle. The rear-view camera system for a vehicle according to one embodiment of the present invention includes at least one wide-angle lens and at least one standard lens, and may take a rear image of the vehicle using the wide-angle lens or the standard lens. According to the embodiment of the present invention, it is possible to reduce an accident risk, while the vehicle is reversing, by providing an image taken through the wide-angle lens or an image taken through the standard lens according to a distance between the vehicle and an object located at a rear thereof or a user'"'"'s selection, and also to observe rules of parking etiquette without any difficulty.

Claims

1. A rear-view camera system for a vehicle, comprising:

a rear-view camera configured to take a rear image of the vehicle using at least one wide-angle lens and at least one standard lens;

a distance detecting part configured to detect a distance between the vehicle and an object located at a rear of the vehicle; and

a central control part configured to switch and output an image taken through the wide-angle lens or an image taken through the standard lens according to the distance between the vehicle and the object located at the rear of the vehicle.

2. The system of claim 1, wherein the rear-view camera further includes an optical member which distributes light indicating an image of an object to the wide-angle lens and the standard lens.

3. The system of claim 1, wherein the rear-view camera further include an optical member which transmits light indicating an image of an object to one of the wide-angle lens and the standard lens.

4. The system of claim 3, wherein the optical member switches the wide-angle lens and the standard lens by rotation thereof.

5. The system of claim 1, further comprising a user operation part which receives a signal for outputting the image taken through one of the wide-angle lens and the standard lens.

6. The system of claim 1, wherein the central control part outputs the image taken through the wide-angle lens when the distance between the vehicle and the object located at the rear of the vehicle is greater than a preset distance, and outputs the image taken through the standard lens when the distance between the vehicle and the object located at the rear of the vehicle is smaller than the preset distance.

7. The system of claim 1, wherein the central control part switches the image taken through the wide-angle lens and the image taken through the standard lens according to a steering direction of the vehicle and a distance between the vehicle and an object located in the steering direction of the vehicle.

8. The system of claim 7, wherein the central control part outputs the image taken through the wide-angle lens when the distance between the vehicle and the object located in the steering direction of the vehicle is greater than a preset distance, and outputs the image taken through the standard lens when the distance between the vehicle and the object located in the steering direction of the vehicle is smaller than the preset distance.

9. The system of claim 1, wherein the image taken through one of the wide-angle lens and the standard lens is processed by a software correction, and then output to a display device.

10. The system of claim 1, wherein a center portion of the rear-view camera has a standard lens shape and an edge thereof has a wide-angle lens shape.
