Claim:
1. An imaging device, comprising: a plurality of pixels including a first pixel and a second pixel; a first comparator having an input terminal coupled to the first pixel via a first signal line, wherein the first comparator is configured to compare a reference signal with a first analog signal supplied via the first signal line; a second comparator having an input terminal coupled to the second pixel via a second signal line, wherein the second comparator is configured to compare the reference signal with a second analog signal supplied via the second signal line; a first switch having a closed position in which the first switch couples an output terminal of the first comparator to an input terminal of a first counter; a second switch having a closed position in which the second switch couples the output terminal of the first comparator to an input terminal of a second counter; a third switch having a closed position in which the third switch couples an output terminal of the second comparator to the input terminal of the first counter; and a fourth switch having a closed position in which the fourth switch couples the output terminal of the second comparator to the input terminal of the second counter.
