Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To measure the opening rate of a black matrix as unevenness of luminance by picking up the light, which is transmitted through a glass panel, and correcting a change of quantity of light. SOLUTION: Correction by a change of luminance due to the transmittance of a glass panel is performed to an image of a black matrix BM panel 1. Image of the glass panel before the coating with BM and a light source 2 are picked up, and unevenness of the luminance of the light source 2 is corrected, and an image for showing the transmittance information of the glass panel before the coating with BM is prepared. This image is used for correction. A high- power television camera 4, which is positioned by a robot 8, picks up an image of the BM panel so as to obtain a BM enlarged image taken into an image processing device 5. Three kinds of BM hole areas and the reference area are used so as to obtain the rate of opening.
