摘要： An imaging apparatus and a method of driving the same that can generate a digital data of a high resolution pixel signal are provided. The imaging apparatus includes: a pixel (10-1) for generating a signal by photoelectric conversion; a comparing circuit (30-1) for comparing a signal based on the pixel with a time-dependent reference signal; a counter circuit (40-1) performing a counting operating until an inversion of a magnitude relation between the signal based on the pixel and the time-dependent reference signal; and a selecting circuit (30-2) for setting a time-dependent change rate of the reference signal, according to a signal level of the signal based on the pixel.

摘要： A photoelectric conversion device includes analog signal output units including pixels and configured to output analog signals based on pixels, and signal processing units. Each of the signal processing units is provided correspondingly to one of the analog signal output units and including a gain application unit configured to apply a gain to an analog signal by using only passive elements and an AD conversion unit. In the gain application unit, a portion that contributes to application of a gain to the analog signal is constituted only of passive elements. The gain application unit selectively outputs a first amplified signal obtained by applying a first gain to the analog signal or a second amplified signal obtained by applying a second gain to the analog signal smaller than the first gain. The AD conversion unit converts, from analog to digital, the first or second amplified signal.
