  • Patent number: 7538750
    Abstract: A method of inspecting a flat panel display including inputting an image data signal into the flat panel display, obtaining an image displayed on the flat panel display in response to the input image data signal with a camera, extracting a raw brightness information corresponding to each location from the obtained image, calculating a fitting brightness information corresponding to each location through the curve fitting based on the raw brightness information, calculating a brightness difference corresponding to each location between the raw brightness information and the fitting brightness information, and detecting stain locations with the brightness difference beyond a predetermined permitted limit.

  • Publication number: 20040114198
    Abstract: An image processing system and an image processing method which correct a moiré in an image taken from a displayed image. An imaging taking apparatus takes an image of an image displayed by an image displaying apparatus and an optical characteristic changing apparatus is provided between the image taking apparatus and the image displaying apparatus. A lightpath of the displayed image is changed before the image of the displayed image is taken and an image processor receives a plurality of the taken images from the image taking apparatus and generates a processed image with a removed moiré by correcting or superposing the plurality of the images. Thus, a processed image, in which a moiré of the displayed image is removed, is promptly obtainable, and a quality of the taken image is increased. The image processing system and method are adaptable to various systems for inspection and/or measurement.
