Patent ID: 7936386

Claim:
A solid-state imaging device that outputs a luminance signal in accordance with an amount of light entering said device, said device comprising: an imaging unit in which plural pixel circuits are arranged one- or two-dimensionally, each pixel circuit including a photoelectric converter, and each pixel circuit outputting a reset voltage and a read voltage, the reset voltage being a voltage generated when said photoelectric converter is reset, and the read voltage being a voltage generated through photoelectric conversion performed by said photoelectric converter; a first signal output line that is connected to a number of said plural pixel circuits and that carries the reset voltage and read voltage output from said number of said plural pixel circuits; a signal output circuit connected to said first signal output line and which outputs, from a second signal output line, a luminance signal in accordance with an amount of light received by said photoelectric converter, based on the reset voltage and read voltage output to said first signal output line; and a high-intensity judgment circuit, connected to said first signal output line via a first capacitor that captures an AC component of a voltage signal in said first output line, said high-intensity judgment circuit that judges whether or not light entering said photoelectric converter is of high intensity based on said AC component of said voltage signal in said first signal output line, and, upon judging that entering light is of high intensity, outputs a luminance signal indicating high intensity to said second signal output line.
