The document describes a new filterless color imaging sensor that combines advantages of CMOS and CCD sensors. It is small, low cost, high resolution, and high sensitivity with low power consumption. The sensor relies on wavelength penetration into silicon to detect red, green, and blue colors at each pixel without using optical filters. This simple innovation allows for a 4 megapixel sensor the size of a current 2 megapixel phone sensor. The technology was developed at a Canadian academic institution and the researchers are seeking partnerships for further development and market deployment.
