Abstract
An imaging sensor has a pixel array in which pixels are disposed in a two-dimensional matrix state, a sampling part, a shutter control part, and a clipping circuit. A vertical signal line is coupled to the plurality of pixels disposed in a column direction, and to which a pixel signal is input from the pixels. The sampling part is coupled to the vertical signal line, and to which the pixel signal output to the vertical signal line is input. The clipping circuit is provided at an input side of the sampling part, and clips an electric potential of the vertical signal line to a first clip level before the pixel signal is input from the pixels to the vertical signal line when the shutter control part performs the global shutter operation. As a result, it is possible to stably operate the sampling part.
