Several methods, devices and systems for correcting rolling shutter artifacts are described. In one embodiment, an image capturing system includes a rolling shutter image sensor that may cause a rolling shutter artifact (e.g., warping). The system includes a processing system that is configured to perform an automatic rolling shutter correction mechanism that utilizes calibration data based on a relationship between pixel locations in an image plane of the image sensor and their corresponding rays of light in a coordinate space. The rolling shutter mechanism determines pixel velocity components based on the calibration data and estimates for each image an aggregate pixel velocity based on an aggregation of the pixel velocity components.

Correcting rolling shutter using image stabilization

Several methods, devices and systems for stabilizing images and correcting rolling shutter effects are described. In one embodiment, a computer implemented method for image stabilization for an image-capturing device with associated calibration data includes determining motion data for the image-capturing device using a motion-estimating device. The method also includes matching motion data to a sequence of frames captured by the image-capturing device to determine motion data for each frame, constructing a target motion path of the image-capturing device based on the motion data for each frame, and computing a desired motion correction from a motion path observed in the motion data to the target motion path.

Methods and systems for image stabilization

A novel layered orthographic representation of the light field, comprising a set of 3-D orientations, each orientation having an associated depth direction and two sampling directions, each such orientation being associated with a set of planar grids normal to the depth direction and containing grid points evenly sampled along the sampling directions, each grid containing orthographic samples of the light field intercepting that grid point in the direction of the associated depth direction. Information of the geometric structure is similarly stored in depth field format at these sample points.
