To develop a lift early warning infrared device  as a part of land or boat (ship) early warning system  the system has the ability to target pre-discovery and instructions invasion. Methods: In support of distant air situation  alerts the enemy aircraft  missiles and other long-range goals  obtain the target type and preliminary judgment of grade  deliver the alarm information to the command system. The infrared alarm device detects the target's own infrared radiation passively  alarms the incoming targets at low altitude and low altitude remote  when radar and other equipment is out of work. Results: The accuracy of entire system reached 20 according the analysis. Conclusions: The device has a full range of complex background  with high sensitivity  high resolution  anti-jamming  fast response time and other characteristics.

In this paper  a color gamut transformation method which transformed the different color gamut into a same one has been proposed. In the transforming process  the deviation which was arose from the quantization error and the truncation error were existing. If the deviation was out of the color tolerance  the uniformity of the screen color will be deteriorated. Firstly  the color tolerance of vision was calculated by the color-difference formula. Secondly  in the full-color LED display experiments  it was analyzed that the tri -color tolerance values are respectively 2.5  2.8 and 1.3. According to the tri -color tolerance values and the color difference formula  the express of the quantization precision  gray value and the color difference was set up. Finally the gray-scale range of the color uniformity was analyzed by the collected data  it was concluded that the uniformity of the display was satisfied the requirement of the visual when the range of the gray level was [11  14]  and when the range was [1  11]  the value of the color difference was also reduced significantly. 2009 IEEE.
