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.
