Abstract
Imaging devices and methods for generating a color image from a low-light scene. A method incudes filtering light from the low-light scene to produce a first light channel having filtered light filtered by a first filter and a second light channel having unfiltered light. The method includes producing a first information channel and a second information channel. The first information channel includes first brightness information corresponding to the first light channel and the second information channel includes second brightness information corresponding to the second light channel. The method includes receiving the first information channel and the second information channel and assigning the first brightness information to a first color channel. The method includes assigning the second brightness information to second color channel and processing the first color channel and the second color channel to produce a full-color image stream. The method includes outputting the full-color image stream.
