METHOD FOR MANUFACTURING LIGHT QUANTITY DISTRIBUTION CORRECTION SHEET, IMAGE PRINTING DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To print an excellent image on photographic film by removing irregular color and irregular illuminance by a light source and further the irregular density of a liquid crystal display panel. SOLUTION: Light from a sub exposing light source 42 passes through a Fresnel lens 44a, an irregularity removing sheet 45, the liquid crystal display panel 46 and further a Fresnel lens 44b. When the light passes through the sheet 45, the irregular lightness and the irregular color of the sub exposing-light source 42 and the irregular density of the panel 46 are removed from the light. After the light from which the irregularity is removed is condensed by a sub image-printing lens 52 and reflected in a specified direction by a total reflection mirror 50, it is projected to the photographic paper 14.
