Abstract
An exposure control for use in photographic color printing apparatus has transducers which are sensitized in the additive primary colors and scan discrete areas of an original to transmit appropriate signals to integrator circuits which, in turn, transmit signals for regulation of the ratio of primary colors in printing light. The transducers further transmit signals to circuits which determine the presence of one or more areas of predominant color in an original and modify the signals which are transmitted to the integrators, either by weakening the intensity or by preventing the transmission of corresponding transducer signals. Detection of areas of predominant color can result in generation of signals which are used to contribute to determination of the total amount of printing light.
