Compression of information from one detector as a function of information from another detector
First Claim
1. A method for compressing image information, comprising the steps of:
- generating first image information regarding a selected scene using a first image detector;
generating second image information regarding the selected scene using a second image detector, the second image information being different from the first image information;
generating compressed information including the steps of;
processing the first image information using an image threshold in order to produce a sequence of threshold images, while dynamically adjusting the image threshold as a function of the second image information; and
using the threshold images to generate the compressed information.

Abstract
A system (10) for compressing video information includes an image detector (12) generating image information regarding a selected scene, a supplemental detector (13, 113, 213) generating supplemental information regarding the scene which is different from the image information, and a processing section (19, 119, 219). The processing section generates compressed information by processing the image information as a function of the supplemental information. The processing section may store the compressed information in a storage section (21), or may transmit the compressed information to a remote device through a communication link (26). The image detector may generate video images of the scene in response to visible light. The supplemental detector may generate images of the scene which represent heat or distance, or may determine the portion of the scene to which an eye (214) of an operator is directed.
