Abstract
A solid-state image capture device includes: a pixel section in which pixels are arranged in a matrix; control lines; a pixel drive section that performs control, through the control lines, an operation of the pixels so as to perform a shutter operation of the pixel section and so as to perform reading; a reading circuit that reads signals from the pixels; and a shutter-mode switching section that controls an operation of the pixel drive section in accordance with a rolling shutter system in which exposure is performed for each row or a global shutter system in which exposure is simultaneously performed on all the pixels. The pixel drive section includes a shutter-mode corresponding section that causes an impedance value from the control lines to a power supply in a global shutter operation to be greater than an impedance value in a rolling shutter operation.
