Graphics display module and method
First Claim
1. A graphics display module for use with an image pickup device, a system memory and an image display device in a computer system, comprising:
- a data compressing device in communication with said image pickup device, compressing a digital image data received from said image pickup device into a compressed image data;
an image data storage unit in communication with said compressing device and said system memory for storing said compressed image data, said compressed image data being transmitted to said system memory in a DMA mode; and
a data decompressing device in communication with said image data storage unit and said image displaying device, decompressing said compressed image data stored in said image data storage unit to recover said digital image data that is then transmitted to said image displaying device for display.

Abstract
A graphics display module for use with an image pickup device, an image data storage unit and an image display device in a computer system includes a data compressing device and a data decompressing device. The data compressing device is in communication with the image pickup device, and compresses a digital image data received from the image pickup device into a compressed image data that is then transmitted to the image data storage unit for storage. The data decompressing device is in communication with the image data storage unit and the image displaying device, and decompresses the compressed image data stored in the image data storage unit to recover the digital image data that is then transmitted to the image displaying device for display.
