Abstract:
1. A solid-state image pickup device comprising: an image pickup pixel unit including a plurality of pixels; a signal processing unit for subjecting a pixel signal outputted from the plurality of pixels to predetermined signal processing; an output buffer unit for outputting the pixel signal processed by said signal processing unit, wherein said output buffer unit outputs said pixel signal and an inverted pixel signal obtained by inverting said pixel signal; and an analog/digital conversion unit for converting the pixel signal into a digital signal in a stage preceding said output buffer unit, wherein said pixel signal and said inverted pixel signal outputted from said output buffer unit are digital signals, wherein all bit data of said pixel signal is outputted by time division from one output terminal of said output buffer unit, and all bit data of said inverted pixel signal is outputted by time division from one inverted output terminal of said output buffer unit, and wherein said pixel signal and inverted pixel signal outputs of said output buffer unit are configured for connection to a next stage that is separate from the image pickup device.
