Abstract
A storage unit stores image data for a window, and a three-dimensional position calculating unit calculates a position for the window in a virtual three-dimensional space so that it appears to be at a position inclined in the depth direction. A perspective projection unit transforms image data so that a window positioned at the calculated coordinates is projected onto a screen in perspective, taking a point in front of the screen as a viewpoint. A frame memory unit holds image data for the window on which perspective projection has been performed, and a display unit displays the window on the screen.
