Image display apparatus

摘要

An image display apparatus having a computer system (100) and an image processor (500). The computer system (100) includes: a personal computer having a CPU (210) and a main memory (220); and input/output apparatuses such as magneto-optical disk drive (300), image scanner (330), color printer (340), etc. The image processor (500) which commonly uses a system bus (150) of the computer system (100) includes an independent dedicated image bus (550), a compression/expansion unit (510), an image memory read/write controller (520), image memories (610, 620, 630), and a video processor (650). Image data which is sent from the magneto-optical disk drive (300) is decoded by the compression/expansion unit (510) and is held in the image memories. The image data of the image memories is transferred to the video processor (650) through a dedicated signal line and is displayed on a large screen projection display (700).
