Abstract
An automatic image-density control system for photo-copying the page-to-page content of an open book, in which optimum values (of exposure or development bias) needed for precisely copying the page-to-page content are initially established by performing either continuous pre-scanning of both pages of an open book or pre-scanning of the second page after completing photo-copying of the first page, and then, based on the optimum values thus established in conjunction with the first page content, photo-copying operation for the first page content is executed, and then, based on the optimum values established for the second-page content, photo-copying operation is sequentially executed for the second-page content.
