Correction device for color film base

Abstract

Abstract PURPOSE: To facilitate an easy adjustemnt for the color balance of the color telecine camera with a high accuracy, thus enchacing the color reproducibility. CONSTITUTION: With preset switch 24 turned off, the color balance error is set for the color film base of each of the R, B and G chromaticity channels via the preset adjuster for gain 25, pedestal 26 and gamma 27 each. The color balance is secured for the color telecine camera in the conventional method and based on the gray scale chart of the monochrome film. Afther this, switch 24 is turned on. As a result, the error component of the color film base is added for each element featuring a good color balance, thus ensuring a high color balance. With correction device of such constitution, the color balance adjustment can be facilitated, thus enhancing the color reproducibility. COPYRIGHT: (C)1980,JPO&Japio
