ABSTRACT:
A video camera system for generating a shutter pulse for operating a photo-camera or other still image recording means in response to detecting a predetermined magnitude change in an average level of a pick-up signal representative of an image. As a detecting signal, both level detecting signals for an iris control and an AGC control, for example, are used. When the status of a foreground object zone is changed with movement of a person or an object, the level change of the image pick-up signal becomes a value larger than a predetermined value and a shutter pulse is automatically generated.
