Patent ID: 8035066

Claim:
A solid-state imaging device, comprising: pixels, arranged in a matrix, each of which converts light into a signal voltage; column signal lines each of which is provided for a corresponding one of columns on which said pixels are arranged, so that the signal voltage generated by a said pixel is provided to a corresponding one of said column signal lines; and AD converters, each of which is provided for a corresponding one of said column signal lines, and configured to convert the signal voltage into a digital signal, wherein each of said AD converters includes: a comparator configured to generate an output signal indicating a greater voltage of the signal voltage and a reference voltage; and a counter configured to count a count value to measure an elapsed time until logic of the output signal is inverted, and said solid-state imaging device further comprises: a suspender configured to receive the output signal generated by said comparator and suspend a power supply to said comparator according to the logic of the output signal.
