Abstract
A solid-state imaging device includes an imager including pixels arranged in a matrix, and analog to digital (AD) converters, each of which is provided in each pixel column and converts a signal voltage read from one of the pixels located in the column to a digital value. Each of the AD converters includes a comparator and a counter section including a counter circuit, which receives a comparison result of the comparator and includes a first D flip-flop (DFF) for n-bits, and a transfer circuit, which includes a second DFF for n-bits holding and outputting a count value of the counter circuit. The second DFFs provided in the columns are coupled in series to form a transfer section transferring the signal voltage which has been digitally converted.
