Infrared and near-infrared camera hyperframing
First Claim
1. An article comprising a machine-readable medium embodying information indicative of instructions that when performed by one or more machines result in operations comprising:
- positioning a first filter in an optical path of an infrared camera at a first time;
receiving infrared light from an object through the first filter at a detector array of the infrared camera;
acquiring first subframe image data for the object using a first integration time based on the receiving the infrared light from the object through the first filter at the detector array;
positioning a second filter in the optical path of the infrared camera at a second later time;
receiving infrared light from the object through the second filter at the detector array;
acquiring second subframe image data for the object using the first integration time based on the receiving the infrared light from the object through the second filter at the detector array; and
generating first superframe image data based on at least some of the first subframe image data and at least some of the second subframe image data.

Abstract
Systems and techniques for improving the dynamic range of infrared detection systems. For example, a mechanical superframing technique may comprise positioning a first filter in the optical path of an infrared camera at a first time, receiving infrared light from an object through the first filter at a detector array, acquiring first subframe image data for the object, positioning a second filter in the optical path of the infrared camera at a later time, receiving infrared light from the object through the second filter, acquiring second subframe image data for the object, and generating first superframe data based on at least some of the first subframe image data and at least some of the second subframe image data.

23. An infrared camera system comprising:
-
a filter holder configured to hold a plurality of filters and to position each of the filters in turn in an optical path of the infrared camera system; a detection system configured to receive light through a first filter of the plurality of filters positioned in the optical path of the infrared camera at a first time and to generate first subframe information using a first integration time based on the light from an object received through the first filter at the detection system, and further configured to receive light through a second filter of the plurality of filters positioned in the optical path of the infrared camera at a second later time and to generate second subframe information indicative thereof using the first integration time based on the light from the object received through the second filter at the detection system; and a processor configured to receive the first subframe information and the second subframe information and to generate first superframe information based on at least a part of the first subframe information and the second subframe information. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
