System for assisting driving of vehicle
First Claim
1. A driving assisting system comprising:
- an imaging device that is mounted on a vehicle to capture images of a rear region of the vehicle including a blind spot region adjacent to the rear region of the vehicle, the blind spot region being outside of a viewing range of a side mirror, and the blind spot region covering a region closer to the vehicle in comparison with the viewing range;
an image processing unit that processes images captured by the imaging device to compress an image region corresponding to the blind spot region on the captured image; and
a display device that displays the image processed by the image processing unit in a manner visible to a driver seated in the vehicle,wherein the image processing unit is configured to compress the image region corresponding to the blind spot region such that the ratio of transition of position of the object in the horizontal direction on the captured image at a position within the image region corresponding to the blind spot region to transition of distance from the vehicle to the object is substantially the same as the ratio of transition of position of the object in a horizontal direction on the side mirror at a predetermined region of the viewing range including its horizontal boundary to transition of distance from the vehicle to the object.

Abstract
Disclosed is a device which is mounted on a vehicle, and captures a rear region of a vehicle and a blind spot region outside of a viewing range of a side mirror adjacent to the rear region of the vehicle. A captured image is subjected to image processing so that the blind spot region on the captured image is compressed. The image after subjected to the image processing is displayed so as to be visible to a driver. The blind spot region on the captured image is compressed so that a sudden change of position of a object in a horizontal direction on the captured image is suppressed, as against a change of distance from the vehicle to the object. Compression is performed so that the ratio of transition of position of the object in the horizontal direction on the captured image to transition of distance from the vehicle to the object is substantially the same as the ratio of transition of position of the object in the horizontal direction in the side mirror to transition of distance from the vehicle to the object. The phenomenon of the object'"'"'s appearance as if the object suddenly accelerates in the vicinity of the vehicle is avoided.
