とするビデオカメラ。 a camera unit that converts optical information into a video signal; a text/graphic information generator that generates text/graphic information;
a character and graphic information synthesis circuit that imprints the text and graphic information from the text and graphic information generation device into the video signal formed by the camera unit; a deck unit that records the signal from the text and graphic information synthesis circuit; and the deck. In the video camera, the text/graphic information synthesis circuit includes a reproduction circuit for reproducing a video signal from the camera section. The structure is such that the text and graphic information can be superimposed every one horizontal synchronization period when compositing, and the playback circuit includes a delay circuit that delays the playback video signal from the deck section by one horizontal synchronization period, and a delay circuit that delays the playback video signal from the deck section by one horizontal synchronization period. The timing of switching between the input signal and the reproduced video signal that does not pass through this delay circuit is controlled by an external mode specification, and either a video signal that includes text/graphic information or a video signal that does not include text/graphic information is output. A video camera comprising: a control means for controlling a video camera;
