    摘要: A column buffer for use with a pixel cell array includes an amplifier coupled to three read-out circuits in parallel providing a signal corresponding to accumulated photon-generated charge in a pixel cell plus noise, a reset level plus noise, and a pedestal level, respectively. These three signals are used to generate an ultra-low noise signal Di=Si−Pi-1−G*(Ri−Ri-1), wherein S is the sampled signal, P is the pedestal level, R is the reset level, and G is a gain associated with a pixel cell, and wherein i is a frame number greater than 0. The three signals can be read-out simultaneously. In another embodiment, the three signals are obtained from a column buffer having only one output. In this case, the signals are read-out sequentially.

    摘要: Aspects of the present disclosure are directed to sensing apparatuses and methods. As may be implemented in accordance with one or more embodiments, analog signals are obtained from a plurality of sensors and used to provide an output for particular ones of the sensors as follows. Analog signals are obtained from a particular sensor and one or more adjacent sensors. Different weighting factors are applied to the analog signals, based on the position of the sensor or sensors. The signals with the weighting factors applied thereto are combined to provide an output signal.
