1. A device comprising:
- a first channel including a first optics component and a first image sensor, wherein the first channel is dedicated to an infrared spectrum;
a second channel including a second optics component and a second image sensor, wherein the second channel is dedicated to a visible spectrum; and
a processing component coupled to the first and second channels and configured to combine outputs of the first and second channels to generate an image.

Abstract
Digital camera systems and methods are described that provide a color digital camera with direct luminance detection. The luminance signals are obtained directly from a broadband image sensor channel without interpolation of RGB data. The chrominance signals are obtained from one or more additional image sensor channels comprising red and/or blue color band detection capability. The red and blue signals are directly combined with the luminance image sensor channel signals. The digital camera generates and outputs an image in YCrCb color space by directly combining outputs of the broadband, red and blue sensors.
