Patent ID: 8511823

Claim:
A method of producing infrared imagery comprising: for each of a plurality of frames, sampling a plurality of foveal array elements of a detector foveal region of a microbolometer array at a faster sampling rate to yield foveal array data; sampling a plurality of peripheral array elements of a detector peripheral region of the microbolometer array at a slower sampling rate to yield peripheral array data, the plurality of peripheral array elements including a plurality of sub-regions, each sub-region including two or more peripheral array elements, and wherein sampling the plurality of peripheral array elements comprises for each sub-region: sampling a first subset of the each sub-region for a first frame of the plurality of frames; and sampling a second subset of the each sub-region for a second frame of the plurality of frames, the second subset not equal to the first subset; processing the foveal array data to yield foveal image data for a display foveal region of a display; and processing the peripheral array data to yield peripheral image data for a display peripheral region of the display.
