Abstract

Abstract A high resolution imaging system having a wide field-of-regard. The wide field image generation system (10) of the present invention is operative to provide a composite digital representation of a scene within a field-of-regard. The invention (10) includes a sensor arrangement (12, 14, and 16) for generating first and second frames of image data. A scene correlator (18) registers the first and second frames of image data within the field-of-regard. A temporal filter (22) averages image data in the first frame with image data at a respective corresponding location in the second frame to provide a third frame of image data. When displayed, the third frame of image data provides a wide field-of-regard, high resolution image with minimal undesirable seams therein.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 119 words
Apparatus for providing a composite digital representation of a scene within a field-of-regard comprising: a sensor for generating first and second frames of analog image data; an analog to digital converter connected to said sensor for digitizing said first and second frames of image data; a first memory for storing said first digitized frame of image data; a second memory for storing said second digitized frame of image data; a correlator for registering said first and second stored digitized frames of image data; a third memory for storing said at least a portion f said first and second registered frames of image data and a temporal filter for weighing, combining and averaging the data stored in said third memory.
Claim 2
Dependent Claim 119 words
Apparatus for providing a composite digital representation of a scene within a field-of-regard comprising: a sensor for generating first and second frames of analog image data; an analog to digital converter connected to said sensor for digitizing said first and second frames of image data; a first memory for storing said first digitized frame of image data; a second memory for storing said second digitized frame of image data; a correlator for registering said first and second stored digitized frames of image data; a third memory for storing said at least a portion f said first and second registered frames of image data and a temporal filter for weighing, combining and averaging the data stored in said third memory.
Claim 3
Dependent Claim 22 words
The invention of claim 1 further including means for converting the digital signals stored in said third memory to analog output signals.
Claim 4
Dependent Claim 14 words
The invention of claim 2 further including means for displaying said analog output signals.
