Abstract

This paper deals with each aspect of converting thermal images into a displayable television format within the constraints of a hand held viewing system. We will consider the data collection technique used, including analog to digital (A/D) conversion criteria necessary to meet system performance goals. Also to be examined is the use of high speed static memories for data buffering and time base correction. The use of dynamic memories for frame storage and scan conversion will be investigated. Furthermore, a technique for frame averaging for noise reduction will be examined. System timing as it applies to television and scan conversion is presented, along with criteria for the video digital to analog conversion (DAC) for producing standard television output.
