  • Publication number: 20240080564
    Abstract: Electronic devices, methods, and program storage devices for achieving smooth zooming operations during video capture are disclosed. In particular, smooth zooming may be desirable during video capture operations that involve a single image capture device and/or transitioning between two or more distinct image capture devices, e.g., having different optical and/or zooming properties, during the video capture. When video zooming is done abruptly, it can lead to an unpleasant user experience. The techniques described herein to improve the smoothness of zooming operations include: the use of longer zoom “ramps” for image capture devices; the “early” transitioning between image capture devices during video capture; and the performance of additional “digital zoom smoothing-aware” video image stabilization operations. The embodiments described herein also provide for a more consistent user experience between video streaming (i.e., “preview”) modes and the recorded (i.e.

  • Patent number: 9355436
    Abstract: A first depth map is generated in response to a stereoscopic image from a camera. The first depth map includes first pixels having valid depths and second pixels having invalid depths. In response to the first depth map, a second depth map is generated for replacing at least some of the second pixels with respective third pixels having valid depths. For generating the second depth map, a particular one of the third pixels is generated for replacing a particular one of the second pixels. For generating the particular third pixel, respective weight(s) is/are assigned to a selected one or more of the first pixels in response to value similarity and spatial proximity between the selected first pixel(s) and the particular second pixel. The particular third pixel is computed in response to the selected first pixel(s) and the weight(s).

  • Patent number: 8878957
    Abstract: In response to an image, a likelihood of flicker within the image is estimated. In response to the estimated likelihood, references are selected from among first and second sets of references. The first set of references are responsive to a first set of reference images captured under particular illumination. The second set of references are responsive to a second set of reference images captured under fluorescent illumination. In response to the selected references, one or more gains are generated for enhancing white balance of the image.
