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.

Detection and mitigation of burn-in for thermal imaging systems

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.

Methods and systems for detection and mitigation of image-flash in infrared cameras

In accordance with one or more embodiments of the present invention, an infrared camera includes an infrared detector providing infrared data and a programmable logic device providing timing and control signals to the infrared detector and processing the infrared data to provide an output signal based on the infrared data. Additional memory devices, if present, may be controlled by the programmable logic device, which manages the flow of information for the memory devices.
