Abstract
Method and system for performing grayscale image generation. The method involves acquiring, by means of a color image sensor, color information from an environment within the field of view of an imaging assembly. The color image sensor comprises a plurality of color pixels, each configured to acquire specific color information from the environment. Each pixel in the array has a different detection spectrum than its nearby neighbors. A processor determines a grayscale value for each pixel in the plurality of color pixels, the grayscale value being derived from color information from a two-by-two array of pixels in the color image sensor. The processor then generates a grayscale image from the grayscale values for each pixel.
