Abstract
In a system for storing and displaying images, such as in a personal computer or mobile telephone, a display apparatus is provided which selectively displays virtual reflections of the real environment according to mirror values encoded with the stored image. A camera (302) provides real-time environmental image data which, under control of the CPU (100), are stored in memory (106, VRAM3). For transparency effects, background image data (RGB2) are mixed (110) with the foreground image (RGB1) under control of a transparency code (T). The resultant pixel values (RGB3) are further mixed with the environmental image data read out of VRAM3 which are left-right reversed (118) to simulate a true mirror image ) for output to the display device (300). The image from another camera (310) can be used in the same manner to provide a virtual transparency function. By controlling the transparency and reflection effects for each pixel of the image, various special effects and a more realistic display can be achieved.
