The visual inspection tool for detecting uneven area defects that appear in a screen of an LCD display by image processing was developed. By differential processing in multiple resolute images that are generated from an original image, various uneven area defects that have different sizes and shapes are detected. Evaluating factors that influence a human visual sensitivity about uneven area defects is experimented. As the experimental result, it was found that various factors about uneven area defects influence a visual conspicuous ratio. Through the inspection, various feature data related to a visual conspicuous ratio about uneven area defects were output.
