  • Publication number: 20120307085
    Abstract: 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.

  • Publication number: 20120307084
    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.

  • Publication number: 20120051636
    Abstract: Some embodiments of the invention provide novel methods for converting the color region of images. For instance, the method of some embodiments converts the color of an image from one color region (e.g., from a Rec. 601 color region) to another color region (e.g., to a Rec. 709 color region). In some embodiments, the method receives the image in a first color format that is non-linearly encoded within a first color region. Without performing a linearization operation to linearize the color component values of the image, the method then converts the image into a second color format that is defined with respect to a second color region. In some embodiments, the color-converted image is non-linearly encoded in the second color region.
