| Summary: | This invention relates to the field of digital imaging. More specifically, the invention relates to a method for reducing motion artifacts in digital imaging.
In generation of combined image data from first and second scans of an image, artifacts caused by motion between the first and second scans are reduced. Digital pixel data for the first and second scans are stored. A translational second scan is generated using the first and second scans, the translational second scan having new digital pixel data which compensates for motion artifacts between the first and second scans. The combined image data is generated by combining the digital pixel data of the first scan with the new digital pixel data of the translational second scan, with the translational second scan being weighted before it is summed with the digital pixel data of the first scan. |
