Abstract: 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.
