发明名称 Solid-state imaging device, driving control method thereof, and imaging apparatus
摘要 A solid-state imaging including a comparing circuit, an inverting circuit, and a masking circuit, and that performs column parallel AD conversion processing of analog pixel signals output from a plurality of pixels arranged in a two-dimensional matrix form. The comparing circuit outputs a difference signal obtained by comparing each of the pixel signals outputted from the pixels with a reference signal having a ramp waveform. The inverting circuit inverts a logic of the difference signal outputted from the comparing circuit. The masking circuit masks an output of an output signal of the inverting circuit to a circuit in a subsequent stage during an input offset canceling period in which the comparing circuit cancels an input offset between the pixel signal and the reference signal.

主权项 1. A solid-state imaging device which performs analog-to-digital conversion processing of analog pixel signals output from a plurality of pixels arranged in a two-dimensional matrix, the solid-state imaging device comprising: a comparing circuit configured to output an output signal obtained by comparing each of the pixel signals output from the pixels with a reference signal having a ramp waveform; and a masking circuit configured to mask the output signal during an input offset canceling period in which the comparing circuit cancels an input offset between the pixel signal and the reference signal, wherein, the masking circuit masks the output signal during a period other than a precharge phase (P-phase) of an analog-to-digital conversion enable period and a data phase (D-phase) analog-to-digital conversion enable period, the period including the input offset canceling period.
