A system, method, device, and computer program product are provided for correcting motion skew in a frame of video or in other images captured using a rolling shutter image sensor. A method for removing motion skew may create a mathematical model of the motion skew, compute the motion skew using the mathematical model of the motion skew, remove the distorted image of the object from view in the image using the computed motion skew, and render a corrected image of the object in the image using the computed motion skew.
1. A method comprising:
computing, with a processor, a representation of a distorted object image using a mathematical model of motion skew from an image that comprises a frame in a video, the representation of the distorted object image providing an approximate shape and location within the image of the distorted object image;
removing the distorted object image from view in the image using the computed representation of the distorted object image;
replacing pixels in an area of the image where the distorted object image has been removed from view with pixels gathered from a corresponding area of a different frame in the video; and
rendering a corrected image of an object in the image using the computed representation of the distorted object image.
