摘要： An apparatus, method, and computer-readable medium for motion sensor-based video stabilization. A motion sensor may capture motion data of a video sequence. A controller may compute average motion data of the camera used to capture the video sequence based on motion data from the motion sensor. The controller may then determine the difference between the actual camera motion and the average camera motion to set a video stabilization strength parameter for the frames in the video sequence. A video stabilization unit may utilize the strength parameter to stabilize the frames in the video sequence.

摘要： Systems, methods, and computer readable media for stabilizing video frames based on information from a motion sensor are described. In general, digital video stabilization techniques are disclosed for generating and applying image-specific transformations to individual frames (images) in a video sequence after, rather than before, the image has been captured. The transformations may be used to counter-balance or compensate for unwanted jitter occurring during video capture due to, for example, a person's hand shaking.

摘要： Systems, methods, and computer readable media for stitching or aligning multiple images (or portions of images) to generate a panoramic image are described. In general, techniques are disclosed for using motion data (captured at substantially the same time as image data) to align images rather than performing image analysis and/or registration operations. More particularly, motion data may be used to identify the rotational change between successive images. The identified rotational change, in turn, may be used to generate a transform that, when applied to an image allows it to be aligned with a previously captured image. In this way, images may be aligned in real-time using only motion data.

摘要： This disclosure pertains to devices, methods, and computer readable media for perforating positional sensor-assisted panoramic photography techniques in handheld personal electronic devices. Generalized steps that may be used to carry out the panoramic photography techniques described herein include, but are not necessarily limited to: 1.) acquiring image data from the electronic device's image sensor; 2.) performing “motion filtering” on the acquired image data, e.g., using information returned from positional sensors of the electronic device to inform the processing of the image data; 3.) performing image registration between adjacent captured images; 4.) performing geometric corrections on captured image data, e.g., due to perspective changes and/or camera rotation about a non-center of perspective (COP) camera point; and 5.) “stitching” the captured images together to create the panoramic scene, e.g., blending the image data in the overlap area between adjacent captured images. The resultant stitched panoramic image may be cropped before final storage.

摘要： Methods and systems to create an image in which objects at different focal depths all appear to be in focus. In an embodiment, all objects in the scene may appear in focus. Non-stationary cameras may be accommodated, so that variations in the scene resulting from camera jitter or other camera motion may be tolerated. An image alignment process may be used, and the aligned images may be blended using a process that may be implemented using logic that has relatively limited performance capability. The blending process may take a set of aligned input images and convert each image into a simplified Laplacian pyramid (LP). The LP is a data structure that includes several processed versions of the image, each version being of a different size. The set of aligned images is therefore converted into a corresponding set of LPs. The LPs may be combined into a composite LP, which may then undergo Laplacian pyramid reconstruction (LPR). The output of the LPR process is the final blended image.

摘要： The invention describes methods and apparatus for the generation of laser radiation with pre-selectable frequency, which could be bigger or smaller than its fundamental beam frequency, through a combination of two or more intracavity frequency conversion processes of two or more resonantly enhanced beams. These techniques are particularly useful for generating continuous wave tunable frequency radiation in uv, visible and infrared wavelength ranges. These processes can be a combination of an intracavity fundamental beam pumped optical parametric oscillation (OPO) and an intracavity sum- or difference-frequency-mixing of the fundamental laser beam with an OPO generated beam and an intracavity frequency doubling the optical parametrical generated signal or idler beam to desirable frequencies for continuous wave. These plural intracavity nonlinear processes can be a combination of an intracavity or resonantly cavity-build-up fundamental beam pumped OPO and another frequency conversion within this OPO and the fundamental cavity. These intracavity enhanced frequency conversion processes allow for minimizing the parent frequency beams' losses and increasing the final conversion and, particularly, highly efficient conversion for continuous waves.
