Abstract

PURPOSE: To enable a color separated positive or negative image having an optional grain pattern or the like, by connecting an oscillating circuit with an electronic circuit for operating various kinds of correction, and superposing the signals of the oscillating circuit on the signals of the electronic circuit.
CONSTITUTION: Either side of output of an oscillating circuit for producing 2 kinds of waveforms, triangular and square waveforms, using transistors Tr1, Tr2 is connected to the output side of an electronic circuit, and the signal of the oscillating circuit is superposed on the signal of the electronic circuit to synthesize a novel signal. As compared to usual dots, the dots thus formed are partially erased or deformed, permitting a grain, worm, or the like pattern to be created visually. Such a pattern can be controlled by changing frequency, waveform, and output voltage of the oscillating circuit, and the frequency can be changed by changing a capacity of capacitor 15 in the circuit. This method renders a special contact screen unnecessary.
