Abstract
PURPOSE:To enable an adjuster to know which adjustment point has been selected at the 1st glance, by placing a cursor at the adjustment point right inside of the selected adjustment point on the screen. CONSTITUTION:A group of cursor keys 15 provided on control panel 1 is operated to select an adjustment point at a desired position. Coincidence detecting circuits 22 and 27 detect coincidences between the contents of horizontal and vertical cursor counters 25 and 20 and those of horizontal and vertical address counters 26 and 21 and, once the coincidences are detected, outputs coincidence signals. With the coincidence signals, gate circuit 33 is controlled and a cursor signal from cursor generating circuit 31 is added by output period adding circuit 35 to a crosshatch pattern signal from crosshatch pattern generating circuit 13. The crosshatch pattern signal having the superposed cursor signal is displayed on the television screen.
