This work describes a novel color pixel topology that converts the three chromatic components from the standard RGB space into the normalized rg chromaticity space. This conversion is implemented with high-dynamic range and with no dc power consumption, and the auto-exposure capability of the sensor ensures to capture a high quality chromatic signal, even in presence of very bright illuminants or in the darkness.

Abstract

This work describes a novel color pixel topology that converts the three chromatic components from the standard RGB space into the normalized rg chromaticity space. This conversion is implemented with high-dynamic range and with no dc power consumption, and the auto-exposure capability of the sensor ensures to capture a high quality chromatic signal, even in presence of very bright illuminants or in the darkness.
