Title:
WIPE OPERATION DISPLAY DEVICE IN VIDEO CAMERA
Document Type and Number:
Japanese Patent JPS6282777
Kind Code:
A
Abstract:
PURPOSE:To facilitate the setting of layout of an object by providing a wipe operation circuit controlling the switching of a gate properly in response to the wiping and a signal changeover circuit using its output signal as a view finder signal. CONSTITUTION:A wipe operation circuit 1 has a gate circuit 2 inputting a camera video signal S1 and a gate signal generating circuit 3 receiving a wiping start trigger so as to give a control pulse S2 controlling the switching of a gate circuit 2 to the gate circuit 2. The output signal of the gate circuit 2 is given to a VTR as a wipe output signal S3 and given as one input of a signal changeover circuit 4 and the camera video signal S1 is given as the other input of the signal changeover circuit 4. The signal changeover circuit 4 is subjected to alternate changeover control by the line changeover pulse S4 of the frequency set to, e.g., 1/2 of the horizontal scanning frequency and the output signal is given as the view finder signal S5. Thus, the setting of layout of the object is facilitated.
