Photographing method and device for video picture

Abstract

Abstract PURPOSE:To generate a color film of a high-quality picture from a television signal, by exposing the image, which is projected to a high-resolution FSS tube by three primary color signals of a color picture, onto the film through three primary color filters individually. CONSTITUTION:R, G, and B picture signals are subjected to A/D conversion and are stored in frame memories 2a-2c, and signals read out by a photographing switch are applied to the luminance modulation terminal of a flying spot scanner FSS tube, which uses a white phosphor and has a high resolution, of a photographing part 7 after the increment of the number of scanning lines in interpolation calculating parts 3a-3c and the adjustment of the hue and the gradation in gradation adjusting circuits 5a-5c, and three primary color filters are switched to expose colors of the image onto a film time-differentially. Thus, the hue and the gradation matched to photosensitive materials are obtained, and a color film of the high-quality picture which has hardly defocusing of the lens and is superior in resolution is obtained form the television signal.
