FIGURE DISPLAYING DEVICE Abstract of the Disclosure A figure displaying device comprises a first generation circuit for generating a brightness signal corresponding to figure information to be displayed, a second generation circuit for generating a brightness modulation signal that varies within a predetermined first region on a display screen, and a third generation circuit for generating a frequency characteristic control signal that varies within a predetermined second region on the display screen. The brightness signal from the first generation circuit is subjected to a brightness modulation in accordance with the signal from the second generation circuit. A control circuit subjects the brightness signal from the first generation circuit to the control of a frequency characteristic in accordance with the signal from the third generation circuit. A figure is displayed on a monitor device on the basis of a modulation signal obtained through the modulation and control circuits. The result is enhancement of quality and increased naturalness in contrast to prior arrangements for the same purpose.
