Abstract
A method and system of correcting motion artifacts are provided for video captured from interlaced multiple exposure sensors. The following are included: (a) motion artifacts detection of a pixel area, (b) smoothing of the detected pixel area, and (c) motion artifacts correction. The motion artifacts pixels are detected by comparing the luma difference between a current image frame and a previous image frame; the pixels of the surrounding area are also checked. A smoothing operation is applied to the detected artifacts area, in order to remove isolated pixels and enlarge the detected area. Corrections are then provided using a multistage filter for the luma channel and a mean filter for the chroma channel.
