Figure displaying device

摘要

A figure displaying device for generating a brightness signal which corresponds to a figure information to be displayed as well as for generating a brightness modulation signal which varies within a predetermined first region on a display screen. The device also generates a frequency characteristic control signal which varies within a predetermined second region on the display screen. Furthermore, the display is able to subject the brightness signal to a brightness modulation in accordance with the signal from the modulator generator with the brightness signal being controlled by the frequency characteristics control signal. The resultant figure displayed on a monitor is based on a modulation signal obtained through the modulation generator and the frequency characteristics control generator.
