WINDOW DISPLAY

摘要

A storage unit 5102 stores image data for a window, and a three-dimensional position calculating unit 5104 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 5106 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 5107 holds image data for the window on which perspective projection has been performed, and a display unit 5108 displays the window on the screen.
