【発明の名称】露光制御方法および写真カラー複写装置
Document Type and Number:
Japanese Patent JP2955720
Kind Code:
B2
Abstract:
A exposure control process and a photographic color copying apparatus make possible the optimal adaptation of the evaluation of a copy master to the varying spectral sensitivities of different copy materials, without having to change the measuring filters. The measuring light components of each of the basic colors are detected by a wavelength selective detection device in at least two closely adjacent spectral ranges and the resultant measured values combined into prevailing color extract values.
