ABSTRACT:
A solid-state image pickup device which has means of adding signals from plural pixels, which achieves a high S/N and a pickup device suitable for both static and moving image pickup. The device has a pixel unit having plural pixels arranged two-dimensionally and outputting pixel signals derived by photoelectric conversion, and has a first mode reading a pixel signal every pixel, and a second mode adding and reading a plurality of pixel signals, having a variable gain column amplifier for performing readout at different gains in the first mode and second mode. The device has plural output lines where signals from plural pixels arranged in one line are outputted respectively, and at least one amplifier is connected to each of the plurality of output lines. Gain at time of second mode readout is higher than gain at time of first mode readout.
