ABSTRACT:
A video camera (10) includes a photographing device (16). The photographing device (16) generates an image signal corresponding to an optical image irradiated on a light-receiving surface, and a monitor (34) displays a moving image based on a generated image signal. An amount of incident light into the photographing device (16) is controlled by an aperture apparatus (14) having an aperture blade that moves to a direction perpendicular to a light axis. A moving amount of the aperture blade is restricted by a predetermined value, and this defines a minimum value of an F number. When the moving image is displayed on the monitor (34), it is prohibited to set to the minimum value of the F number.
