Paper Abstract

This paper describes an automated color defect inspection system of color imaging devices. The system uses color image processing technology, but does not use conventional primary color (R,G,B) components. In this system, two kinds of chrominance signals (R-Y, B-Y) are introduced to analyze color images. Newly developed color edge detection and color contrast calculation methods are used to detect and evaluate the color defects. Color contrast are calculated by analyzing the two dimensional chrominance signal's scatterplot. Algorithms of color defect inspection and experimental results are presented.
