Abstract

PURPOSE: To magnify a designated part of the contents displayed on a display device at one side and to display this magnified part on a display device at the other side, by making use of a frequency converting circuit.
CONSTITUTION: A desired part to be magnified and displayed for a picture displayed on a display device 12 is designated in a rectangular form by an input device 2 and supplied to a microcomputer 4. The computer 4 converts the frequencies of both horizontal and vertical lines of said rectangular form by the dividing circuits 6 and 7 and a counter circuit 9 and supplied to a memory 10. Then the horizontal and vertical lines of said designated part are magnified and displayed on a display device 11 by reading out the contents of the memory 10. In such a way, the original display contents are held by the display device 12 and only a designated part can be magnified and displayed on the display device 11 respectively.
