摘要:
An imaging system is provided that includes a pixel array having a plurality of columns with rows of pixels and with each pixel having a plurality of photodiodes and a common readout circuit that stores respective accumulation voltages from each of the plurality of photodiodes. Moreover, the system includes row driver circuitry that control the pixel array for pixel addressing and readout, such that the respective accumulation voltages of the photodiodes is read out on a readout channel coupled to a bit line column, and a hybrid multiplexer that multiplexes and routes output signals from the pixel array to a video imaging device to be displayed thereon.
