ABSTRACT:
A video camera has a normal operation control mode in which a normal operation is allowed to be performed and a demonstration mode in which each of a plurality of functions of the video camera is sequentially executed for a predetermined period of time, and is arranged to permit switching between the normal operation control mode and the demonstration mode. When a visual-line detecting circuit, a switch mounted on an eyecup, a sensor composed of a light-emitting element and a light-receiving element, or the like, detects that the operator is viewing an electronic viewfinder during the demonstration mode, the demonstration mode is switched over to the normal operation control mode. The demonstration mode is resumed upon detection of detachment of the eye of the operator from the electronic viewfinder.
