Abstract

An inspection instrument for stripe pattern, which is used to inspect the RGB stripe pattern of the black matrix film formed on the inner surface of the panel of a color cathode ray tube; which is characterized in comprising: a CCD camera attached with an automatic focusing mechanism, a horizontal moving mechanism part for maintaining and moving the CCD cameral, a rotation mechanism part for rotating the horizontal moving mechanism, an image processing part for separately processing and inspecting the stripe pattern from an amplified image taken by the CCD camera, and a light source for transmission.
