Eye of the beholder: FPGAs convert CMOS imager output to human-viewable RGB

摘要

CMOS imager Bayer-pattern pixel data conversion to RGB pixel data can be readily accomplished using today's low-cost FPGA technology devices. Pixels within modern CMOS image sensors are typically arranged in a Bayer color pattern. Figure 1 presents an example of that pattern.rnImage data is scanned from left to right and from top to bottom. Each scanned raw pixel is a monochrome color element, either Red or Green or Blue. Inherent characteristics of the human eye make it advantageous to have twice as many green pixels as red or blue ones.
