Method of displaying shot image on car reverse video system

摘要

A method of displaying a shot image on a car reverse video system is described, which is applicable for adjusting an image displaying angle of the car reverse video system with a fixed lens according to a distance from an obstacle. Firstly, a scene image behind the car is shot through using the lens. Then, a distance detector is activated to detect a distance from the obstacle behind the car. If the distance from the obstacle is smaller than a preset distance, a scaling ratio is set according to a ratio of the preset distance to the distance from the obstacle. Finally, according to the scaling ratio and a distance between each pixel in the scene image and a reference point, all pixel pitches are adjusted, such that the scene image is deformed, and thus achieving an effect of switching a viewing angle of the scene image.
