Title:
LIGHT BEAM RECORDER
Document Type and Number:
Japanese Patent JPS63244968
Kind Code:
A
Abstract:
PURPOSE:To constantly make a picture density corresponding to the same picture signal constant by fluctuating the quantity of light of a light beam based on the temperature of a sensitive material. CONSTITUTION:The light beam 2 is modulated based on the picture signal outputted from a picture signal output device 11 and a picture is recorded on the sensitive material 7 as the latent image of a photograph. The picture signal is passed to a signal converting part 12, the signal is converted based on a prescribed converting table, converted to an analog signal in a D/A converter 14 and inputted to a modulation circuit 15. The converting table is formed by a converting table forming part 13 based on the temperature of the sensitive material detected by a temperature sensor 9.
