Captured images free of noise are acquired with an arbitrary shutter speed. There is provided an imaging device that includes a solid-state image sensing device including a light-receiving unit in which there is disposed a plurality of light-receiving elements, vertical transfer units, and a horizontal transfer unit, the solid-state image sensing device being adapted such that the charge stored in each of the plurality of light-receiving elements is read to the vertical transfer units, the charges read to the vertical transfer units are vertically transferred at a first transfer rate for a high-rate transfer period, and the charge in each of the vertical transfer units is vertically transferred at a second transfer rate slower than the first transfer rate for a normal-rate transfer period following the high-rate transfer period, to thereby output the charges supplied to the horizontal transfer unit for the normal-rate transfer period as valid ones from the horizontal transfer unit, a memory to provisionally save image outputs read from the solid-state image sensing device, and a timing generator to control the operations of the solid-state image sensing device and memory, the timing generator providing such a control that when generating a charge sweep-away signal for an effective video period other than horizontal blanking, the solid-state image sensing device stops the horizontal-transfer operation during generation of the charge sweep-away signal to continuously read image outputs via the memory.
