Abstract

A high sensitivity, single chip, low light level imaging device is provided. The imaging device of the present invention utilizes sparse color sampling, to maximize the luminance information gathered. In particular, color information is gathered by a small proportion of the pixels included in an image sensor, while the remaining pixels operate at full spectrum sensitivity. The present invention allows the correct hue of objects to be determined, while providing high sensitivity to available luminance information in a scene. In addition, the present invention allows hue information to be ascribed to objects in a scene, even in combination with luminance data collected over a spectrum that includes the near infrared and infrared wavelengths.
