Solid-state imaging device

A solid-state imaging device which 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 conversion unit, and each pixel circuit outputting a reset voltage and a read voltage, the reset voltage being a voltage generated when said photoelectric conversion unit is reset, and the read voltage being a voltage generated through photoelectric conversion being performed by said photoelectric conversion unit;
• a first signal output line which is connected to a number of said pixel circuits and which carries the reset voltage and read voltage outputted from said 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 conversion unit, based on the reset voltage and read voltage outputted to said first signal output line;
• and
• a high-intensity judgment circuit connected to said first signal output line via a first capacitor, which judges whether or not light entering said photoelectric conversion unit is of high intensity based on a voltage signal in said first signal output line, and, upon judging entering light of high intensity, outputs a luminance signal indicating high intensity to said second signal output line.
