Abstract:
A solid-state imaging device which can, in response to the problem of black-crush occurring in an image when strong light is enters the device, positively detect black-crush in a state in which a variance margin has been secured. The solid-state imaging device outputs a luminance signal in accordance with an amount of received light, and includes: a pixel circuit having a light-receiving element; a signal output circuit having a sampling transistor which outputs, from a second signal output line, a luminance signal in accordance with the amount of light received by the light-receiving element, based on an output signal from the pixel circuit; and a high-intensity judgment circuit which is coupled by the pixel circuit and a judgment input coupling capacitor, judges whether or not light entering the light-receiving element is of high intensity based on the output signal from the pixel circuit, and in the case of judging the entering light to be of high intensity, outputs a luminance signal indicating high intensity.
