A programming method for SVGA in infrared test system was introduced. By utilizing the inner functions of the display adapter, real-time display of full-gray-scale infrared images was realized, and VCR mode in traditional infrared test stations can be substituted. Some pivotal subroutines and techniques were described and several results were given as examples. It was shown that the method for direct transforming and display of image data by programming for SVGA was advanced and effective.
