    摘要： A regenerative amplifier system that is optimized for low-gain gain media is provided. The system is configured to include a minimum number of intra-cavity elements while still eliminating the leakage of the seed pulses from the output beam. In addition, the contrast ratio of the amplified pulses is increased even considering the long build-up time that is required in low-gain regenerative amplifiers. This is accomplished using a single Pockels cell between the oscillator and amplifier to select a single seed pulse for the cavity, instead of using a Faraday isolator. This directs the unwanted seed pulses in a separate direction from the output pulse. When the amplified pulse exits the cavity, it is directed in a direction away from the oscillator by the same Pockels cell. Only one additional Pockels cell and one polarizer are required inside the regenerative amplifier cavity.

    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.
