Abstract:
1. A solid-state imaging apparatus comprising: pixel circuits each of which outputs an analog pixel signal of a voltage corresponding to an incident light quality; a reference voltage generating circuit which generates first through Nth reference voltages; and successive comparison type A/D converters each of which performs an A/D conversion of the analog pixel signal, based on the first through Nth reference voltages; wherein the A/D conversion includes a coarse A/D conversion for performing a first normal comparison operation and a fine A/D conversion for performing a second normal comparison operation and a redundant comparison operation, wherein the successive comparison type A/D converter includes: wherein the D/A converter includes: a capacitor array which, when the fine A/D conversion is performed, generates the analog reference signal, based on the (n−1)th through (n+2) the reference voltages selected by the multiplexer.
