摘要： Various techniques are disclosed to detect and mitigate the effects of burn-in events occurring in thermal imaging systems. Such events may be attributable to the sun (e.g., solar burn-in) and/or other high thermal energy sources. In one example, a method includes detecting a burn-in event that causes thermal images captured by a focal plane array (FPA) to exhibit a blemish; and mitigating the blemish in the thermal images. In another example, a thermal imaging system includes a focal plane array (FPA) adapted to capture thermal images; and a processor adapted to: detect a burn-in event that causes the thermal images to exhibit a blemish, and mitigate the blemish in the thermal images.

摘要： Methods and systems for mitigating undesirable video flash in infrared camera systems are disclosed. A frame of video can be stored in a buffer and information related to the frame of video can be processed prior to displaying the video such that the processed information facilitates display of the video substantially without flashing. A display of a non-flashed frame can be frozen while a flash event would otherwise cause a flashed frame to be displayed. The shift in a histogram caused by a flash event or some portion thereof can be subtracted from pixels of an image. Thus, image quality can be substantially enhanced.

摘要： Systems and methods provide infrared camera techniques that may improve image quality or infrared camera performance over a range of varying conditions. For example, in accordance with an embodiment of the present invention, a system is disclosed that transforms data provided by an infrared camera based upon environmental conditions at the time the data was obtained. As an example, the image quality provided by the infrared camera may be improved over a range of environmental conditions by the proper transformation of the data based upon the sensor's information.

摘要： A camera system exhibiting reduced effects from temperature changes. The camera system includes an IR sensor; an optical arrangement adapted to focus incoming light onto the sensor; a processing arrangement adapted to process signals produced by the sensor; a heatsink in thermal contact with and is adapted to transfer heat energy away from, the processing arrangement; and a thermal equalizer. The thermal equalizer at least partially surrounds and is in thermal contact with the optics/sensor unit and is formed at least partially from a material having a high thermal conductivity. The thermal equalizer conducts heat energy from warmer to cooler parts of the optics/sensor unit. The thermal equalizer is also thermally insulated from ambient air surrounding the camera system and from the heatsink.
