摘要
For compensating for misalignment of pixels at the time of reproduction in a Holographic Digital Data Storage (HDDS) system, and thereby correcting an image, a stored page-based image is detected using a Charge Coupled Device (CCD) through a one-to-one (1:1) pixel matching between data pixels and CCD detector pixels at the time of reproduction. And then, in case the misalignment of pixels occurs during the 1:1 pixel matching, an amount of the misalignment d (0≦d1) between a corresponding data pixel and a corresponding CCD detector pixel is calculated. Further, an interference influence of a neighboring pixel on the corresponding CCD detector pixel is calculated based on the calculated amount of the misalignment, to thereby correct image data of the CCD detector pixel. And last, a misalignment influence in accordance with the amount of the misalignment is compensated for, to thereby correct the image data of the CCD detector pixel.
