摘要

1. A solid-state imaging device, comprising: a column processing section comprising a low-bit bit latch section, wherein the low-level bit latch section is configured to receive the output signal of the comparator from the comparator and the output signal of the count from the counter and fix the count value. 2. The solid-state imaging device of claim 1, wherein the counter is configured to output an output count signal so that the output count signal moves only one bit. The solid-state imaging device according to claim 2, wherein the counter is a Gray code counter. The solid-state image forming apparatus according to claim 3, wherein the low-level bit latch section comprises a plurality of low-level bit latch circuits. The solid-state image forming apparatus according to claim 4, wherein the column processing section further comprises a high level bit counting section, wherein the high level bit counting section is adapted to receive an output signal of a latch of one of the low level bit latch circuits farthest to the high level side of the section latches low bits, and performs counting operations. 6. The solid-state image forming apparatus according to claim 4, wherein the Gray code counter is configured to output a plurality of Gray code account values, each of the low bit bit latch circuits is configured to receive at least one of the Gray code account values. The solid-state imaging device according to claim 5, wherein the comparator is configured to compare a reference signal with analog
