Video camera

[0025]With reference to FIG. 1, a video camera 10 of this embodiment includes an optical lens 12 and an aperture unit 14. An optical image of an object scene through these members is irradiated onto a front surface, i.e., an imaging surface, of an imaging portion 18 configuring a CMOS-type image sensor 16, and is then photoelectrically converted. Thereby, a raw image signal formed of electric charges representing an object scene image is generated.

[0026]When a power supply is turned on, a CPU 30 instructs a TG Timing Generator) 22 configuring the image sensor 16 to repeatedly perform an exposure and an electric-charge reading-out. The TG 22 applies to the imaging portion 18 a plurality of timing signals responding to a vertical synchronization signal Vsync outputted from an SG (Signal Generator) 24 in order to repeatedly execute an exposure operation of the imaging surface and a reading-out operation of the electric charges obtained thereby. The vertical synchronization signal Vsync is
