    Abstract: An Augmented Reality (AR) providing method using an instant marker or a substitution marker is provided. According to an example, the instant marker or the substitution marker is created based on a 3-dimensional object. A meaning unit of an original 2-dimensional marker is analyzed and a marker factor corresponding to the meaning unit is extracted from the image of an object that is to be used to the instant marker or substitution marker. The meaning unit is mapped to the marker factor to create the instant marker or the substitution marker based on the object, so that a user may use AR using the instant marker or substitution marker.

  • Patent number: 7903101
    Abstract: A display device and method with an optimal external input setting capability are provided. A method for setting an external input in a display device includes receiving information about an external device which is connected to the display device via a network; determining based on the information about the external device whether the external device has a capability of providing a component output signal; and if the external device has the capability of providing the component output, setting a set of component terminals as a set of external input terminals for receiving a signal from the external device. Thus, when the external device has the capability of providing a component output, the component terminal is set as an external input, thereby obtaining a high definition image. In addition, setting the component terminals as the external input is automatically performed, thus providing convenience to a user.
