description	PURPOSE:To expose an image of any gradation on a photosensitive material by a simple construction by exposing the photosensitive material with lighting beams from a cathode ray tube. CONSTITUTION:The title device is provided with a time modulation means 13 varying pulse width according to the level of input video signals, and the cathode ray tube 16 emitting light of fixed brightness at the timing of pulse signals subjected to time modulation. According to the level of the video signal, the light emitting time of the cathode ray tube 16 is controlled, and the area of the photosensitive material 1 on which light is projected varies in accordance with the level. Ultmately, excellent exposure is performed to correspond with the gradation of videos projected on the photosensitive material 1.
