Abstract:
To reduce flicker appropriately according to illumination condition of an imaging subject, a video camera is provided. The video camera includes an imaging unit for generating a subject image; a superimposing image generator for generating a superimposing image; an image synthesizer for synthesize the subject image and the superimposing image to generate a synthesized image; a video signal generator for generating a video signal from the synthesized image so as to display the synthesized image. The video camera also includes a flicker reduction unit to reduce flicker caused by luminance fluctuation of a light source. The flicker reduction unit has a plurality flicker reduction modes. The mode setting unit makes the superimposing image generator to generate a settings screen as the superimposing image for assisting selection of one of the flicker reduction modes.
