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.
Claims24
An image capture device comprising:
- a plurality of sensors;
- a plurality of optics components, wherein each optics component of the plurality of optics components is configured to pass light to a sensor of the plurality of sensors, the plurality of optics components comprising a first optics component and a second optics component, wherein the second optics component has at least one different performance characteristic than the first optics component;
- and
- a processing component configured to control an integration time of each sensor.
A system comprising:
- a plurality of channels wherein each channel of the plurality of channels includes a sensor, the plurality of channels comprising a first channel configured to detect a first band of light and a second channel configured to detect a second band of light;
- and
- a processing component coupled to the plurality of channels, wherein the processing component is configured to determine an integration time of each channel of the plurality of channels, wherein the processing component is configured to combine data from the plurality of channels received to provide an image.
A method comprising:
- identifying an integration time for each of a plurality of channels of an image capture device, wherein the plurality of channels includes a plurality of sensors, the plurality of sensors comprising a first sensor and a second sensor, wherein the second sensor has at least one different performance characteristic than the first sensor;
- capturing data with each of the plurality of sensors, wherein the data captured by each sensor is based at least in part on the integration time of the respective sensor;
- and
- generating an image by combining the data captured by each of the plurality of sensors.
