US Patent 7259772 Apparatus, method, and medium for controlling image orientation

An apparatus, method, and medium for controlling image orientation are disclosed. An orientation mode detector measures multi-directional rotational angles of a display panel and determines an orientation mode for original image data based on the measured rotational angles. A system memory stores orientation parameters corresponding to a plurality of image orientation modes. A system controller initially acquires information indicating the orientation mode from the orientation mode detector, and it extracts orientation parameters corresponding to the acquired information from the system memory. Finally, a driver changes an orientation of the original image data according to the extracted orientation parameters.
