METHOOD FOR PATTERN DETECTING OF OVER-SAMPLING IMAGE, APPARATUS FOR OPTICAL INFORMATION PROCESSING BY USING SAME AND METHOD FOR OPTICAL INFORMATION PROCESSING BY USING SAME

摘要

A method for detecting pattern of over-sampling image, an apparatus for processing optical information by using the same and a method for processing optical information by using the same are provided to improve the reliability of the reproduced optical information by finding the data having a specific pattern like a mark at the image of an oversampled data page. A method for detecting pattern of over-sampling image comprises: a step(S110) detecting the detection image of a data page by oversampling the data page; a step comparing the detection image with the reference image of the oversampling to the pattern through covariance; and a step producing the pixel of the oversampled pattern with the detection image compared by covariance and the value of the reference image.
