  • Patent number: 9749608
    Abstract: An apparatus and a method process a stereoscopic image. More particularly, an apparatus and a method improve compression performance of stereoscopic image data in a portable terminal. The apparatus includes a camera unit including at least two camera modules spaced about a certain distance apart. The camera unit is configured to obtain a first image and a second image to be used to constitute stereoscopic image data. The apparatus further includes a three-dimensional (3D) data generation unit configured to change a compression ratio of the first image and the second image obtained by the camera unit.

  • 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: 7949193
    Abstract: An apparatus and method for efficiently compressing three-dimensional stereoscopic images are provided. The apparatus and method include a search for Global motion between left and right images input through two image input units mounted in a mobile communication terminal. The images are arranged and a difference between the two images is computed. The images are compressed using the difference between the two images and a reference image. Accordingly, because the left and right images are similar, a computation amount can be reduced since the global motion is computed only once.

  • Patent number: 7778654
    Abstract: Disclosed are a system and method for controlling home appliances using a short message service. When receiving a short message including an access code from a mobile terminal, the home server checks the status of the connected home appliances and sends a short message including control codes corresponding to the status of the home appliances to the mobile terminal. The mobile terminal checks the control codes to confirm the status of the home appliances, and displays corresponding images. When the user requests to control the status of a specific home appliance, the mobile terminal automatically generates a corresponding short message and sends the short message to the home server. The home server checks the message, controls the corresponding home appliance, and then sends a short message including current status information of the controlled home appliance to the mobile terminal.

  • Publication number: 20090172563
    Abstract: A method and an apparatus for using user created content stored in a Subscriber Identity Module (SIM) card as a user interface is provided. According to the method and apparatus, the SIM card stores the user created content, and a terminal platform executes and displays the user created content if any one of the user created content stored in the SIM card is selected. A Java platform receives the selected user created content from the SIM card, and transmits the received user created content to the terminal platform.
