Abstract:
A solid-state imaging device, a method for driving a solid-state imaging device, and an electronic apparatus are provided that are capable of reducing memory circuits of a column reading system, so that the column reading system can achieve a reduced layout area and eventually a reduced size. A column reading circuit includes an AD converting part and a calculating part. The AD converting part is configured to analog-to-digital convert a read-out reset signal and a read-out signal of a pixel signal read to a vertical signal line into an n-bit digital pixel signal. The calculating part includes an n-bit asynchronous counter including a retention circuit with a control logic function, which is configured to obtain a difference between an n-bit read-out reset signal and an n-bit read-out signal produced by the AD conversion performed by the AD converting part.
