DEVICE AND METHOD FOR DATA RECOGNITION BY CODE BOOK METHOD AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To accurately an image relating to image data to be inputted by easy operation processing even without adjusting the position and size of the image relating to the image data. SOLUTION: The characteristic data of the image data is extracted on the basis of comparison results of characteristic vector data generated by extracting sequentially imputed image data while shifting a starting point extracted by a characteristic vector data generating part 104 with a plurality of code vectors in a code book storing part 106, and a characteristic data comparing part 112 compares the characteristic data with characteristic data in a characteristic data storing part 111. Since characteristic data in which position deviation of the image data is corrected can be obtained in this way, it is possible to accurately recognize the image relating to the image data to be inputted by the easy operation processing even though the position of the image data deviates from that of image data with which the characteristic data in the storing part 111 is generated.
