SYSTEM AND PROCESS FOR CAPTURING, PROCESSING, COMPRESSING, AND DISPLAYING IMAGE INFORMATION
First Claim
1. A process for capturing and compressing security image information, comprising:
- capturing a background image;
transmitting the background image for use by a receiver;
a) capturing an image;
b) comparing the image to the background image;
c) generating a change file responsive to the comparison;
d) transmitting the change file for use by the receiver;
repeating steps a-d for a sequence of images;
receiving feedback information from the receiver; and
adjusting step a, b, c, or d responsive to the feedback information.

Abstract
A process and camera system is provided for capturing and compressing video image information. The compressed data may be efficiently transmitted to another location, where cooperating decompression processes are used. The compression process first captures a background image, and transmits the background image to a receiver. For each subsequent image, the image is compared at the camera to the background image, and a change file is generated. The change file is then transmitted to the receiver, which uses the background image and the change file to decompress the image. These changes may be aggregated by both the camera and the receiver for even better compression. In some cases, the background may be removed from the displayed image at the receiver, thereby displaying only changing image information. In this way, a display is less cluttered, enabling more effective human or automated monitoring and assessment of the changing video information.
