Abstract: An image display apparatus calculating correction information to correct measured values of an orientation sensor includes an orientation sensor that senses orientation of a viewpoint and outputs measured values, a correction unit for correcting the measured values by using correction information, and a generation unit for generating a virtual image based on the corrected measured values. A display unit displays the generated virtual image, and a calculation unit calculates the corrected information. The calculation unit obtains the measured values of the sensor at the point of when the virtual image is displayed at an appropriate position, generates the correction information from the measured values and predetermined orientation information, and generates the virtual image based on orientation information relating to the viewpoint obtained using the measured values of the orientation sensor and the correction information.

Abstract: Disclosed is a method and apparatus in which the image of a received data content is converted to accord with the color space of an OSD to be displayed on a screen upon reproducing the colors of a received digital broadcast data image. The apparatus includes: a browser for analyzing information on received video and data content and displaying an image obtained from the analyzed information; a selective switch part for switching modes of the color space of an output OSD according to a selection control by a user; a converter engine for checking the mode of the color space selected by the selective switch part, setting a property of the color space of the output OSD according to the checked mode, and converting a bitmap image of the data content to accord with the set color space; and a display part for displaying the set and converted color space on the OSD.
