IMAGE REPRODUCTION SYSTEM WHICH DETECTS SUBJECT BY SENSING INTENSITY RATIOS

摘要

This specification discloses an image reproduction system in which an array of photocells is employed to sense intensity ratios in the subject image focused in the array. An analog circuit responsive to the signals developed by the photocells produces logarithmic output signals representing the lightness of discrete areas in an image focused on the photocell array. The output signals of the analog system energize lamps of a lamp array to reproduce the subject image.
