Abstract
A video camera () includes a photographing device (). The photographing device () generates an image signal corresponding to an optical image irradiated on a light-receiving surface, and a monitor () displays a moving image based on a generated image signal. An amount of incident light into the photographing device () is controlled by an aperture apparatus () 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 (), it is prohibited to set to the minimum value of the F number.
