The present invention relates to a method for driving a solid-state image pickup
device and a camera provided with the driving function. In the method for driving
the solid-state image pickup device and the camera according to the present invention,
the frame rate of the image pickup device is varied according to the frequency
of illumination or the brightness. Alternatively, the frame rate of the image pickup
