摘要： An imaging device may have a monochrome image sensor and a bi-chromatic image sensor. A beam splitter may split incident light between the two image sensors. The monochrome image sensor may have an array of broadband image sensor pixels that generate broadband image signals. The bi-chromatic image sensor may have an array of red and blue image pixels that generate red and blue image signals. The image sensors may be coupled to processing circuitry that performs processing operations on only the broadband image signals to produce monochrome images, or on the red, blue, and broadband image signals to produce color images. Processing operations used to produce color images may include chroma-demosaicking and/or point filter operations.

摘要： 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.

摘要： Imaging systems providing high resolution, low light images with significant dynamic range are disclosed. The improvements to photo imaging sensors providing low costs and yet higher performance sensors may be obtained an enhanced photosensor generating a single color channel image per photosensor. The single color channel image contains luminence values corresponding to light focused onto the photosensor. The plurality of photosensors are constructed using Indium gallium nitride (InGaN) nanowire structures and nanopyramid structures used in cells within an array of cells. Photosensors may be constructed as single color imaging devices as well as multi-color devices. The generation of various color channel images are controlled using metasurface filter structures as well as color filter layers setting a wavelength for absorbed light by controlling a concentration of indium gallium nitride (InGaN) within the color filter layers.

摘要： The invention enables image processing of visible light and near-infrared light using an imaging device. An acquisition unit (110) acquires an image signal representing an image including near-infrared light that has an intensity according to a pattern having a prescribed geometric shape. A signal processing unit (120) uses pattern information which defines the pattern to output, a color signal representing visible light components corresponding to the image signal and a near-infrared signal representing near-infrared light components corresponding to the image signal.

摘要： A multispectral image capture device includes a filter wheel (4) and an image sensor. The filters (41-46) are located close to a focusing plane of a light beam used to form the images, and at least one of the filters is more angularly narrow than the optical field of the image sensor. The production of the filter is thereby facilitated. Advantageously, the filters are closer to one another in the wheel such that multiple filters are in the optical field of the sensor simultaneously. Each multispectral image can be captured more quickly than when each filter covers the entire optical field of the sensor.

摘要： An imager including a self test mode. The imager includes a pixel array for providing multiple pixel output signals via multiple columns; and a test switch for (a) receiving a test signal from a test generator and (b) disconnecting a pixel output signal from a column of the pixel array. The test switch provides the test signal to the column of the pixel array. The test signal includes a test voltage that replaces the pixel output signal. The test signal is digitized by an analog-to digital converter (ADC) and provided to a processor. The processor compares the digitized test signal to an expected pixel output signal. The processor also interpolates the output signal from a corresponding pixel using adjacent pixels, when the test switch disconnects the pixel output signal from the column of the pixel array.
