Abstract:
1. A solid-state imaging device comprising: a plurality of pixel circuits each including a photoelectric conversion element; a plurality of reading signal lines connected to the plurality of pixel circuits; a reference signal output circuit outputting a reference signal whose voltage level varies; a reference signal line connected to the reference signal output circuit; and a plurality of comparators each having a first input terminal and a second input terminal and each inverting its output depending on a voltage relation of the first input terminal and the second input terminal, wherein the first input terminals of some of the plurality of comparators are connected to the reading signal lines and the second input terminals thereof are connected to the reference signal line, and wherein the first input terminals of the other of the plurality of comparators are connected to the reference signal line and the second input terminals thereof are connected to the reading signal lines.
