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.
