ビデオカメラ。[Claims for Utility Model Registration] Electric zoom equipped with a zoom direction designation circuit that specifies the direction of current supplied to the zoom motor to either the wide-angle direction or the telephoto direction depending on whether the operated zoom switch is a wide-angle direction switch or a telephoto direction switch. A video camera with a function includes an audio detection circuit that outputs an audio detection signal when the audio signal input from the microphone is at a predetermined level or higher, and a wide-angle direction specification and telephoto control when the audio detection signal from this audio detection circuit is input. a voice-sensitive control circuit that gives a small-step reciprocating shift command that alternately repeats direction specification to the zoom direction designation circuit; and a small-step shift operation switch inserted between the voice-sensitive control circuit and the zoom direction designation circuit. A video camera with an electric zoom function.
