A color separation prism includes a filter, a first prism, a second prism, and a third prism. The first prism allows incidence of light transmitted through the filter, and the first reflective film reflects a first color component of the visible light and a part of the invisible light, among the light beams incident on the first prism. The second prism emits the light reflected by a second reflective film, and the second reflective film reflects the second color component of the visible light and a part of the invisible light, among the light beams incident on the second prism. The third prism emits the light transmitted through the second reflective film. The first reflective film and the second reflective film allocate the invisible light and the visible light emitted from each prism so as to obtain approximately uniform amount of the light.

An image sensor assembly includes at least one upconverter configured to detect light in a NIR waveband that is received from an object to be imaged and generate, based on the detected light, upconverted light that is outside of the NIR waveband; and at least one image sensor configured to detect the upconverted light.

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.

A method includes sampling a first intensity of light with a first array of photo detectors of a digital camera. A second intensity of light is sampled with a second array of photo detectors of the digital camera. A first channel processor coupled to the first array of photo detectors generates a first image using first array data which is representative of the first intensity of light sampled by the first array of photo detectors. A second channel processor coupled to the second array of photo detectors generates a second image using second array data which is representative of the second intensity of light sampled by the second array of photo detectors. The first array of photo detectors, the second array of photo detectors, the first channel processor, and the second channel processor are integrated on or in a semiconductor substrate.

An imaging device according to an embodiment includes an image sensor, and processing circuitry. The image sensor is a rolling-shutter type image sensor that includes a plurality of pixels that are arranged in a matrix and generate an electric signal due to light received and, on a frame-to-frame basis, repeatedly performs a process to sequentially start to conduct exposure on at least every line, starting from the first line of the pixels to the last line, and output the electric signal sequentially from the line for which exposure has been completed. The processing circuitry causes the pixels to receive light during only a period based on the blanking period that corresponds to the period from when the output of the electric signal from the last line is finished until the output of the electric signal from the first line is started. The processing circuitry generates images in accordance with the electric signal.

A digital camera includes a plurality of channels and a processing component operatively coupled to the plurality of channels. Each channel of the plurality of channels includes an optics component and a sensor that includes an array of photo-detectors.

The processing component is also configured to combine data from the plurality of channels to generate an image.
