Claim Text:
1. A solid-state imaging apparatus including a plurality of pixels, and conversion units each configured to A/D-convert a signal from each of said plurality of pixels, each of said conversion units comprising a comparison unit configured to receive a reference signal, and compare an analog signal from said pixel with the reference signal, a sampling unit configured to receive a first clock signal, and sample a signal level of the first clock signal based on an output of said comparison unit, a counter configured to receive the first clock signal, and count, based on the output of said comparison unit, a time until a magnitude relationship between the analog signal and the reference signal is reversed, and an output unit configured to output a digital signal corresponding to the analog signal based on a count result of said counter and a sampling result of said sampling unit, and said sampling unit comprising a first latch unit configured to latch the output of said comparison unit in response to the first clock signal, a second latch unit configured to latch the output of said comparison unit in response to a second clock signal having a phase different from that of the first clock signal, and a third latch unit configured to latch an output of said first latch unit in response to an output of said second latch unit.
