Linear recording condition in multirecording telecine system.
Since the multirecording telecine system includes the negative photographic film as a component, it is a nonlinear system. In this paper, the distortions of the three electrical primary color signals generated by the film nonlinearity are analyzed and represented as the function of the film gamma gamma and recording level. The chromaticity errors of the reproduced image are calculated for various values of gamma and recording level k The condition where the color differences of all colors are less than 7.5 is defined as the linear recording condition. The regions of gamma and k to satisfy this linear recording condition are calculated.
