Title: IN-STREAM ROLLING SHUTTER COMPENSATION
Abstract:
In-stream rolling shutter compensation may be utilized to modify image data to compensate for detected camera motion. An image processor may perform motion matching on image data received from a camera sensor to determine whether and how the camera is moving. Strips of image data are analyzed to find matching locations between the current image and a previous image by generating graphical profiles for each image strip. The graphical profiles for the current strip are compared to corresponding profiles from the previous image to determine matching locations between the two frames. A motion vector for the strip may be computed based on spatial distances between the match locations of the current image and corresponding match locations of the previous frame. Image data for the current strip may be modified based on the motion vector to compensate for perceived camera motion as it is written out to memory.
