METHOD AND SYSTEM FOR IMAGING AN EXTERNAL SCENE BY EMPLOYING A CUSTOM IMAGE SENSOR
First Claim
1. A method for imaging a scene external and forward of a controlled vehicle, comprising:
- filtering light received from the scene with a GRRB filter array integrated into an image sensor;
generating image data corresponding to the filtered light;
receiving and analyzing image data in a controller; and
calculating a GRRB color metric to determine if the filtered light is one of a headlamp and a taillight of another vehicle.

Abstract
A method and system are provided to image an external scene by employing a custom image sensor. The custom image sensor may use a GRRB array to filter the images of oncoming and preceding vehicle taillights captured by a vehicle camera. The method and system may also calculate a GRRB color metric for use in the custom image sensor by performing interpolation on a number of color channels, summing the brightness values for each of the color channels interpolated, normalizing each of the brightness values, and converting the normalized brightness values from an RGB scale to a linear scale of non-red to red.
