A video camera which is provided with an inter-line type CCD and also which enjoys a function as a digital still camera. The video camera includes an irising mechanism for adjusting a quantity of light incident upon the CCD, an iris driving circuit for driving the irising mechanism, and a camera microcomputer for controlling operations of adjusting an incident-light quantity by the irising mechanism by controlling the iris driving circuit. The camera microcomputer controls the iris driving circuit to drive the irising mechanism, whereby the incident light upon the CCD is blocked to perform only a read-out operation while data of all the pixels is read out from the CCD.
