Claim:
A solid-state image capture device comprising: a pixel section in which pixels are arranged in a matrix, each pixel converting an optical signal into an electrical signal and storing the electrical signal in accordance with exposure time; control lines through which the pixels are driven and controlled; 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; wherein, the pixel drive section selects at least one of the control lines when exposure is performed in the rolling shutter system and selects all of the control lines when exposure is performed in the global shutter system, and 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, the shutter-mode corresponding section includes an impedance element connected between a power-supply terminal of the pixel drive section and at least one of power-supply lines of a power-supply potential and a reference potential, the impedance element in the shutter-mode corresponding section includes a resistor having a resistance value RREG expressed by RREG=RDRIVE/X (20≦X≦M/10), where RDRIVE indicates an on-resistance of the drivers and M indicates the number of control lines, and the pixel-drive section has: (a) a control-line selection circuit that selects at least one of rows of the control lines, a control signal being to be output to the pixels in the selected row; and (b) a control-line selection driver section including drivers that amplify a signal from the control-line selection circuit and drive the control signal for the pixels to the corresponding control lines.
