Abstract:
1. A semiconductor integrated circuit device, comprising: a black-level sample/hold amplifier sampling and holding a black-level signal outputted from either of a first or second image sensor; a sensor selecting section selecting, based on a selection control signal, each output destination of the pixel signal outputted from either of said first or second image sensor and of the black-level signal outputted from said black-level sample/hold amplifier; a first amplifying portion sampling/holding the black-level signal and the pixel signal, and amplifying the black-level signal and the pixel signal; a second amplifying portion amplifying the black-level signal and the pixel signal outputted from said first amplifying portion; and an A/D converter converting, to a digital signal, the black-level signal and the pixel signal outputted from said second amplifier, wherein said sensor selecting section selecting a first line as the output destination of the black-level signal and a second line as the output destination of the pixel signal during coupled to the first image sensor, or selecting the first line as the output destination of the pixel signal and the second line as the output destination of the black-level signal pixel signal during coupled to the second image sensor, wherein the black-level signal outputted from the first image sensor is smaller than the pixel level outputted from the first image sensor, and the black-level signal outputted from the second image sensor is larger than the pixel level outputted from the second image sensor.
