Detection and/or correction of suppressed signal defects in moving images
Abstract:
Techniques are described for detecting a vertical line artifact in an image captured with a digital camera. The vertical line artifact may be caused by a defect in the digital camera. Techniques also are described for correcting a vertical line artifact in an image captured with a digital camera. It may be determined that the vertical line artifact includes at least one pixel in the vertical line having a non-zero suppressed signal. A value for the pixel having the non-zero suppressed signal may be determined. A statistically-based correction may be applied to the pixel having the non-zero suppressed signal based on the determination that the pixel has a non-zero suppressed signal and the determined value of the pixel. The image may be a portion of a movie stored on a DVD.
