Latest progress of IR image system processing electronic

Foreign first-class thermal imager manufacturers have developed new generation high-performance image processing electronics which are suitable for their products. A comparative analysis of hardware design architecture, functions and external interfaces is done for five representative sets of high-performance IR image processing electronics. Analysis shows: electronics is divided into analog processing part and digital processing part; a FPGA with plenty resource is used as a core processor, which associated with large memories, and embedded cores in the FPGA is widely used also; besides base image processing functions, better non-uniformity correction and image enhancement algorithms is applied to reinforce image performance; processing electronics usually have expansion capability and can deal with images which resolution is larger than or equal to 640×512 pixels; analog output is VGA; etc.
