  • Publication number: 20160349936
    Abstract: A screen outputting method performed at an electronic device is provided. The screen outputting method includes dividing a display of the electronic device into a first area and a second area, outputting first content to the first area and outputting second content to the second area, receiving an input associated with the first area, and changing a method of outputting the second content based on an attribute of the input.

  • Patent number: 9367941
    Abstract: An image output apparatus and a method of rendering an image thereof are provided. The method includes: a data input configured to receive stroke attribute information; a vertex generator configured to generate a vertex which indicates an outer appearance of a stroke based on the stroke attribute information; an alpha value setter configured to calculate a size of a texture based on the stroke attribute information and set an alpha value that will be stored in the texture; a UV setter configured to set UV information based on the stroke attribute information; a renderer configured to render the stroke based on the vertex, the texture in which the alpha value is stored and the UV information; and an output configured to output the rendered stroke.

  • Publication number: 20130300733
    Abstract: An image processing method to remove aliasing and an image processing apparatus thereof are provided. The image processing method includes receiving data information of a polygonal image, determining a position of an interpolation vertex on an exterior of vertexes of the polygonal image using the data information of the polygonal image, interpolating a space between the polygonal image and a polygon constructed by the interpolating vertex, and outputting an interpolated polygonal image according to the interpolated space. Accordingly, when complex polygons are displayed or the image size changes, the aliasing can be removed. Further, because the interpolating process is applied to primitives instead of a whole image to overcome the aliasing, the amount of calculations decreases.

  • Publication number: 20110216076
    Abstract: An apparatus and method for providing a highly-realistic animation effect in a portable terminal. An apparatus for providing an animation effect in a portable terminal includes an animation processing unit increasing the realism of an animation by performing a composite animation scheme that continuously processes a key frame animation, which is represented in a fixed pattern, and a physical animation that is realistically represented according to peripheral environments.

  • Publication number: 20110159892
    Abstract: An apparatus and method for identifying if station information of a public transportation is information corresponding to a destination by generating and broadcasting guide information including station information to a plurality of portable terminals in a mobile communication system are provided. The apparatus includes a position information system for generating and broadcasting information on the next station, and a portable terminal for receiving the broadcasted guide information and determining if the next station is a station corresponding to a destination.
