Camera Image Stabilization Patents (Class 348/208.99)
  • Patent number: 10341562
    Abstract: Video information generated by an image sensor for a capture period and motion information of the image sensor during the capture period may be obtained. The video information may define images of a video based on light received within a field of view of an image sensor during the capture period. Relative positions of the image sensor between different moments within the capture period may be estimated based on the motion information. Depth information for a portion of an environment of the image sensor may be determined based on the video information generated at the different moments and the relative positions of the image sensor between the different moments, or based on stereo depth mapping. A translational motion correction may be applied to one or more of the images based on the depth information and the relative positions of the image sensor to warp the image(s) and stabilize the video.

  • Patent number: 10194072
    Abstract: A communication system provides for automated detection, and resolution, of focus hunt. A server determines whether a predetermined number of blur metric transition (BMT) cycles, associated with a video stream, have occurred within a predetermined period of time or number of frames. In response to determining that the predetermined number of BMT cycles have occurred, the server determines that focus hunt has occurred. A BMT occurs when first and second blur metrics, determined for first and second video frames, transition from being greater than a blur metric threshold to being less than the threshold, or vice versa. In turn, a BMT cycle occurs when a BMT, of a first BMT and a second BMT, comprises a transition of blur metrics from less than the threshold to greater than the threshold and the other BMT comprises a transition of blur metrics from greater than the threshold to less than the threshold.

  • Patent number: 9860450
    Abstract: The effect of camera shake in digital video is corrected using signal processing techniques. The digital video is a sequence of digital images. When the sequence of digital images are being captured, movement of the imaging device causes the images to shift on the image sensor of the imaging device and affects the quality of the eventual video. Movement of the imaging device is detected while the video is being captured, and a motion information representing the motion is recorded. A processor determines a correcting filter based on the motion information and user input. The processor modifies the sequence of images captured according to the correcting filter and obtains a final corrected video. Corrected video is displayed in a viewfinder.

  • Patent number: 9854170
    Abstract: Embodiments relate to adjusting an image frame based on motion sensor data. An image frame including image data for a plurality of rows of the image frame is captured sequentially row-by-row. Motion sensor data corresponding to the image frame is also captured. Motion vectors describing motion between each row of the image frame are determined based on the motion sensor data. An image data translation is calculated for each row of image frame based on the motion vector for the row. The image frame is adjusted based on the image data translation for each row of the image frame to generate an adjusted image frame.

  • Patent number: 9851527
    Abstract: In various embodiments light redirection device positions of one or more optical chains are moved between image capture times while the position of the camera device including the multiple optical chains remains fixed. The sequentially captured images are combined to form a larger image than is captured during a single time period. Multiple optical chains are used in parallel, each with its own image sensor and light redirection device, in some embodiments. Depth information may and in some embodiments is generated and used to combine the images in a manner intended to minimize or avoid parallax distortions in the composite image which is produced.
