Abstract
Methods, systems, and computer program products for digital imaging in an ambient light deficient environment are described. The methods, systems, and computer program products described include an imaging sensor with an array of pixels for sensing electromagnetic radiation, an emitter that is configured to emit a pulse of electromagnetic radiation, and a control unit that includes a processor. The control unit is in electrical communication with the imaging sensor and the emitter. The control unit is configured to synchronize the emitter and the imaging sensor so as to produce a plurality of image reference frames. The plurality of image reference frames include a luminance frame with luminance image data and a chrominance frame with chrominance data, where the plurality of image reference frames are combined to form a color image.
