This paper describes an uncooled infrared (IR) camera especially optimized for small size & weight, less power consumption without degrading noise equivalent temperature difference (NETD). This camera has two features, including a wafer-level chip scale vacuum package with 160x120 SOI-diode array and germanium lid for good IR transmission, and also a real-time signal correction capability with respect to ambient temperature. These features enabled the considerable size/power consumption reduction and the operation without thermoelectric cooler (TEC) which usual IR cameras require for temperature stabilization. As a result, we realized compact infrared camera (less than 71grams) with low-power consumption and excellent NETD of 22 mK (F/0.8 optics).

The low cost improved recognition of an uncooled infrared image processing has been required urgently for the development of high sensitive uncooled sensor like a cooled sensor. In this study, the uncooled infrared image taken by YBaCuO bolometer camera was improved with applying a special low cost image processing systems. The improved image with this processing exhibited not only the edge enhancement in a large contrast area but also the suppression of heat noise in a small contrast area. It is clarified that this improved recognition image processing is easy to realize at low cost, and the demand for this image processing will be expected to grow up as the use of uncooled infrared sensor system increases.
