摘要:
A driving method used for a solid-state imaging device according to the present invention includes: imaging an object for a first storage time when a shutter is open, in a first state that is a state where either at least a part of the peripheral circuitry is suspended or a consumption current of the peripheral circuitry is limited; imaging, in the first state, a dark output signal image including only a dark output for a second storage time when the shutter is closed; converting the dark output signal image to correspond to the image obtained for the first storage time and subtracting, from the signal image of the object, the converted dark output signal image or converting the dark output signal image to correspond to the image obtained for the second storage time and subtracting, from the signal image of the object, the converted dark output signal image.
