  • Publication number: 20200034994
    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: 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.
