## Abstract

A wide-angled display system for automobiles incorporates the use of multiple cameras whose captured images are processed to produce an integrated view, as if viewed directly by human eyes. This integrated view avoids the blind spots inherent in the 3 rear view mirrors currently used. A pseudo-car image (PCI) program logic is described and claimed to transform images of large moving object into smaller objects taking up same length/volume, at the time the large object is approaching from behind, to correct driver misjudgment problem.

## Claims

### Claim 1

A wide-angled image display system for automobiles, comprising:
a. a plurality of cameras mounted on the rear and both sides of an automobile;
b. a display monitor mounted on the inside of the automobile into the center rearview mirror so that the images received from said cameras are projected and superimposed on the mirror surface of the center rearview mirror;
c. a control unit with image distributor that receives the images from said cameras and generates a composite wide-angled image on said display monitor; and,
d. a set of program logic coded and loaded into the control unit, whereby said logic:
transforms images of larger vehicles behind into images of smaller vehicles in tandem, taking up the same length as the larger vehicles, before transmitting to said display monitor, when images of the larger vehicles appear from the two sides to the rear of current vehicle,
disables the transformation function of the larger image to smaller image when the front of that larger image is flush with the tail end of current vehicle, or if there is any portion of overlapping in the latitudinal direction.
