Abstract

PURPOSE:To record magnetically an electrical signal and to faciliate the color adjustment by installing plural filters between a color-photo negative and a light source for irradiating constant light to said photo negative and converting the light transmitted through the photo negative into the electrical signal by means of a video camera. CONSTITUTION:The titled device is constituted in such a way that light of constant luminance from a condensed light source 1 is irradiated to a color photo negative 2, and yellow, magenta and cyan filters 3, 4 and 5 are disposed at specified intervals in the light path between the light source 1 and the photoplate 2. The filters 3-5 are engaged with pinions 9-11 through racks 6-8, respectively, and the pinions 9-11 are coupled to adjusting knobs 15-17 of shafts 12-14, respectively. A video camera 21 converts the flux of light which passed through the photo negative 2 into an electrical signal to apply it to a monitor television 22 and a magnetic recording device 23. A computer is given the adjusted color quantity of a potentiometer 18 installed at one end of the shafts 12-14 to facilitate the color balanding and the adjustment of a lightness level.
