Abstract

PURPOSE: To develop the contrast according to the change in the intensity of phtosignal, by converting a sound signal into an electric signal, converting it further into a photosignal and sequentially scanning a nonexposed film on it with the photosignal.
CONSTITUTION: A signal from an input device 12 like a microphone passes through a frequency filter 14, the signal is synthesized with a signal from an operation processing circuit 5 and the result enters a signal processing circuit 6. The signal from this circuit 6 is converted into a photosignal at a discharge tube 8 via an enlargement and shrinking circuit 7 and fed to a nonexposed film 11 on a recording cylinder 10 via lens 9. The recording cylinder 10 is turned toward the circumference and either one of the recording cylinder 10 or photospot is moved axially, allowing to make exposure on the entire surface of the nonexposed film 11. The change in the intensity according to the change in the amplitude, frequency and waveform of the input sound is appeared as contrast on the entire film to create a picture.
