摘要： An imager having optically and electrically black reference pixels in each row of the imager's pixel array. Since the reference pixels of each row experience the same row-wise noise as active imaging pixels in the associated row, the signals from the reference pixels are used to cancel out row-wise noise from the row of imaging pixels. The reference pixels are designed such that their photosensors are physically or effectively removed from the row-wise noise correction, thus rendering them electrically black or dark. As such, the reference pixels can be used to provide row-wise noise correction without the adverse effects of warm and hot pixels.
摘要翻译：在成像器的像素阵列的每行中具有光学和电黑色参考像素的成像器。由于每行的参考像素经历与相关行中的有源成像像素相同的行方向噪声，所以来自参考像素的信号用于抵消来自成像像素行的逐行噪声。参考像素被设计成使得它们的光电传感器被物理上或有效地从行方式的噪声校正中去除，从而使它们电黑或黑。因此，参考像素可用于提供行方向噪声校正，而不受热像素和热像素的不利影响。

摘要： A method of operating an imager pixel that includes the act of applying a relatively small voltage on the gate of a transfer transistor during a charge acquisition period. If a small positive voltage is applied, a depletion region is created under the transfer transistor gate, which creates a path for dark current electrons to be transferred to a pixel floating diffusion region. The dark electrons are subsequently removed by a pixel reset operation. If a small negative voltage is applied to the transfer gate, electrons that would normally create dark current problems will instead recombine with holes thereby substantially reducing dark current.
