  • Publication number: 20040012696
    Abstract: A method for correcting a deficient image signal without lowering the resolution of a display page. The method includes generating an image signal of a subject pixel and image signals of peripheral pixels arranged about the subject pixel. A maximum level and a minimum level of the image signals of the peripheral pixels are detected. The method generates a first reference value by adding a first offset value to the maximum level and a second reference value by subtracting a second offset value from the minimum level. The method further includes generating a correction signal using at least one of the image signals of the peripheral pixels, and replacing the deficient image signal with the correction signal when the level of the image signal of the subject pixel is greater than the first reference value or less than the second reference value.
