Abstract

PURPOSE: To increase the picture efficiencies of various kinds, by cascade connection of a number of unit delay elements and converting the coordinate of display picture with a simple operation.
CONSTITUTION: The input terminal of the vertical and horizontal multiplexers 2, 4 is respectively connected to the unit element of the vertical and horizontal unit delay element groups 1, 3, and the selection switch element connecting the selection output terminal is connected to the output terminals 6 and 7. With the operation of the switch, only the video signal at the center on the screen is delayed by reference delay time, and to the video element signal at the location apart from the direction against the scanning from the reference position, the delay time having positive or negative delay difference depending on the distance from the reference position is given, allowing to display the picture shrinking or enlarging the original picture by taking the reference position as the axis as to the scanning direction.
