Abstract

PURPOSE:To smooth the tone visually, by adding a superimposing signal having greater amplitude according to the input signal level to an input signal indicating density or multiplying the superimposing signal having a constant amplitude with said input signal which indicates density. CONSTITUTION:A superimposing signal 11 is added to a signal 10 if it has greater amplitude according to the level of the signal 10. If the signal 11 is constant independently of the level of the signal 10, it is multiplied with the signal 10. Thus, the signal 10 is converted into an output signal 13 where the amplitude is changed depending on the level of the signal 10. The printer is controlled by the signal 13 and the intermediate tone is displayed.
