  • Method and apparatus for displaying graphical user interface depending on a user's contact pattern
    Patent number: 8749510
    Abstract: A graphical user interface (GUI) may be displayed on a display unit in an apparatus which may include a tactile sensor unit. When a contact by a user is detected at the tactile sensor unit, a control unit may receive a contact detection signal therefrom. Based on the contact detection signal, the control unit may determine a contact pattern and may then display the GUI corresponding to the contact pattern. The GUI may be displayed and modified depending on the location and pressure of contacts by a user's manipulating fingers. Therefore, a user can manipulate the apparatus without any inconvenience or accidental touches.

  • Apparatus and method for classifying images
    Patent number: 8704910
    Abstract: An image classification apparatus and method for Automatic White Balance (AWB) are provided. An input image is divided into blocks including pluralities of pixels. A hue value and a chroma value are calculated for each of the blocks. A color-changed block is detected by calculating, for each one of the blocks, differences between the hue and chroma values calculated for all blocks adjacent to the one of the blocks and the hue and chroma values calculated for the one of the blocks. A hue variance and a chroma variance are calculated for the entire input image if a number of the detected color-changed blocks is greater than or equal to a first threshold. The input image is determined as a non-monochromatic image, if the hue variance is greater than or equal to a second threshold or the chroma variance is greater than or equal to a third threshold.
