  • Publication number: 20160353012
    Abstract: A zooming control method is disclosed to perform following operations. A graphical user interface is displayed, and the graphical user interface includes a preview image corresponding to the zooming scale of the camera. A user input is received to assign the zooming scale for zooming in or zooming out the camera. The camera is natively capable of adopting the zooming scale within a scalable range between a wide bound and a telephoto bound. In response to a determination that the zooming scale assigned by the user input is wider than the wide bound of the scalable range, a panorama view mode is launched on the graphical user interface. The preview image during the panorama view mode is generated by the camera adopting the zooming scale at the wide bound, displayed within a central part on the graphical user interface and surrounded by a blank area on the graphical user interface.

  • Patent number: 9324136
    Abstract: A method, an electronic apparatus, and a computer readable medium for processing reflection in an image are proposed. In the method, a first image and a second image are obtained. A plurality of objects in the first image and the second image are recognized and a plurality of lighting regions having a brightness higher than a first threshold in the first image and the second image are detected. Then, a plurality of displacements between corresponding objects and corresponding lighting regions in the first image and the second image are calculated. It is determined whether a ratio of the displacement of the object nearby one of the lighting regions to the displacement of the lighting region is over a second threshold. Finally, the lighting region is determined as a reflection if the ratio is over the second threshold.
