| 摘要 |
The present invention relates to a method for an automatic alignment of digital image layers, implemented in specific software on a computing device (e.g. a personal computer (1)) which drives an image scanner (3) and aligns the multiple scanned image layers (25) in such a way, that of these layers (25) one resulting image (10) will be created, which has - by a statistical calculus based on multiple sampling and averaging of these multiple scanned image layers (25) - a decreased random distributed noise spectrum compared to single scanned images (25) and by the automatic alignment avoids a decrease in sharpness using statistical comparison of the multiple layers (25), especially deviation and cost functions, aiming to compensate a misalignment (6), e.g. mechanical mismatches of the scanner's (3) scanning carriage, between multiple scans (25). |
