  • Patent number: 11004241
    Abstract: A method and an apparatus produce and reproduce Augmented Reality (AR) contents in a mobile terminal. In the method, contents are produced. An image including an object corresponding to the contents is recognized. Recognition information for the object corresponding to the contents is obtained based on a recognition result. AR contents including the contents and the recognition information are generated. Therefore, AR contents for an input image may be easily produced and reproduced, and the AR contents may be used as independent multimedia contents, not an auxiliary means of other contents.

  • Patent number: 10389995
    Abstract: An apparatus and a method synthesize additional information while rendering an object in a 3D-based terminal. A disparity of the additional information is determined with a value that is equal to a disparity of an object or greater than the disparity of the object by a predetermined value in a situation in which the object hidden by the additional information is to be synthesized using a depth buffer. The additional information is overlaid on an image with consideration of the determined disparity of the additional information.

  • Patent number: 9225960
    Abstract: An apparatus and method for attenuating a stereoscopic sense of a stereoscopic image. To generate a stereoscopic image to which a disparity is applied, an object for which a stereoscopic sense attenuation is performed is extracted from among at least one object in the stereoscopic image, a stereoscopic sense attenuation degree corresponding to a position of the at least one object is calculated, and a final stereoscopic image in which the calculated stereoscopic sense attenuation degree is applied to the extracted object is output. Accordingly, a stereoscopic sense of a stereoscopic image displayed to overlap a display screen edge is attenuated, thereby minimizing eye fatigue and visual displeasure.

  • Patent number: 9118955
    Abstract: An apparatus and a method for processing a stereo image are provided. In the method, a first image and a second image are obtained via a first camera module and a second camera module installed spaced by a predetermined distance. When the stereo image is captured, the first image and the second image are alternatively sampled with a predetermined time interval. The sampled at least one first image and the sampled at least one second image are encoded. Therefore, the stereo image can be compressed with low complexity compared to the case of compressing a stereo image using a 2D image compression technology.

  • Patent number: 8949313
    Abstract: A mobile terminal and a method for controlling a function of the mobile terminal using contents are disclosed. The contents are authored to include function control information related to the function of the mobile terminal desired to be controlled. The mobile terminal downloads the contents and registers the function desired to be controlled included in the contents to a service table. The application of the mobile terminal does not execute the called function as it is if the predetermined function is called, but identifies if the called function is registered in the service table. If the called function is registered, the application cancels the existing execution routine for the called function and requests the contents player of the service related to the called function. Then, the contents player controls the called function according to a method programmed in the contents.
