Abstract

The video signal preprocessing unit (processor) for thermovision camera, developed by the authors on the basis of a pyroelectric vidicon, is intended for: calculation of a difference between the `positive' and `negative' frames, obtained in obturation mode; n-divisible accumulation of the resulting frame; non-volatile storage of the received images; images transmission to the computer. These functions are realized by means of following units: video signal digitizer; arithmetic-logical unit; accumulation; display and archive memory units; microcontroller. Processor is developed with Field Programmable Gate Arrays use. Its structure is considered.
