  • Patent number: 10228240
    Abstract: A depth camera assembly (DCA) determines distances between the DCA and objects in a local area within a field of view of the DCA. The DCA includes an illumination source that projects a known spatial pattern modulated with a temporal carrier signal into the local area. An imaging device capture the modulated pattern projected into the local area. The imaging device includes a detector that comprises different pixel groups that are each activated to captured light at different times. Hence, different pixel groups capture different phases of the temporally modulated pattern from the local area. The DCA determines times for light from the illumination source to be reflected and captured by the imaging device from the phases captured by the different pixel groups and also determines distances between the DCA and objects in the local area based on deformation of the spatial pattern captured by the imaging device.

    Abstract: The embodiments include systems and methods for guiding a user to capture two flash images of a document page, and selectively fuse the images to produce a binary image of high quality and without loss of any content. Each individual image may have an FSR where the content is degraded/lost due to the flash light. The idea is to first guide the user to take two images such that there is no overlap of flash-spots in the document regions. The flash spots in both images are detected and assessed for quality and extent of degradation in both images. The image with lower degradation is chosen as the primary image and the other image as secondary, to minimize fusing artifacts. The region in secondary image corresponding to the FSR in the primary is aligned to the primary region using a multiscale alignment technique.

  • Patent number: 9787901
    Abstract: A mobile terminal and controlling method thereof are disclosed, by which a stabilization correction or a preset correction is performed depending on whether a destabilization is recognized from at least one object contained in an image. The present invention includes a display, and a controller operably coupled to the display and configured to cause the display to display a first image, cause the display to display a second image when destabilization of at least one object included in the first image is detected, the second image being an image of which destabilization correction is performed on the at least one object, and cause the display to display a third image when no destabilization of the at least one object is detected in the first image, the third image being an image of which preset correction is performed on the first image.
