ABSTRACT:
A camcorder which can record and reproduce an image signal, and more particularly relating to a camcorder character editing circuit which can change control pulses recorded on a control track of a tape, thereby recording character information, so that the control pulses can be read out during the reproducing process to thereafter display the character information on an existing image signal. A control circuit outputs character information data and a predetermined control signal to a control head, to thereby be recorded on a control track, and during a reproduction process, outputs character information, detected by a data detecting circuit, to an on-screen-display integrated circuit to thereby display the character on a screen and to thereafter obtain a control signal from the control signal data.
