摘要： A dual mode camera may have a camera module and a light source. The camera module may include a quasi-bandpass filter for passing visible light and passing an attenuated portion of near-infrared light to an image sensor for detection. A processor may determine an ambient lighting condition corresponding with an amount of ambient visible light detected by a photodetector. In response to a first ambient lighting condition, the processor may send a first control signal to an encoder to encode image data in monochrome, and another signal to activate a light source. In response to a second ambient lighting condition, the processor may send a second control signal to the encoder to encode image data in color. The light source may emit a band of near-infrared light corresponding with an atmospheric absorption band. The quasi-bandpass filter may attenuate a portion of near-infrared light corresponding with the same atmospheric absorption band.

摘要： The disclosed imaging device includes pixels each including a photoelectric convertor, a focus controller controlling a focal position of light, and a pixel controller controlling charge accumulation in the photoelectric convertors and readout of signals from the pixels. The pixels include a first pixel outputting signal corresponding to light in a first wavelength band and a second pixel outputting signal corresponding to light in a second wavelength band. The pixel controller executes, during one frame, a first period of accumulating charge in the photoelectric convertor of the first pixel in a state that the light in the first wavelength band is focused on, a second period of accumulating charge in the photoelectric convertor of the second pixel in a state that the light in the second wavelength band is focused on, and a third period of reading out signals corresponding to amount of charge generated in the photoelectric convertors.

摘要： A camera for use in automotive applications includes a lens system having a modulation transfer function (MTF) tuned to process light in a spectral range from red to green with greater resolution than light in a spectral range from blue to violet. The camera also includes an imager having pixel sensors arranged in a matrix and a color filter matrix including multiple color filter elements, each corresponding to a pixel sensor of the imager. The color filter matrix includes red filter elements and yellow filter elements and the number of yellow filter elements is greater than the number of red filter elements.
