Improved environment light adaptive method based on tactical information terminal

Abstract

The invention discloses an improved environment light adaptive method based on a tactical information terminal. The method comprises steps that an external light source is acquired by the tactical information terminal; (b), external environment light intensity is determined, and corresponding processing is carried out; and (c), GPU image rendering is carried out. According to the method, the image processing technology is utilized, the image processing engine GPU of the tactical information terminal is utilized, the vision light display technology in different rendering levels under different light environments is carried out for the display image, screen display under the strong light environment is made to still have the relatively high identification degree, the propagation scope of screen display light is reduced as much as possible in the night fight environment to improve crypticity, on the condition that normal operation of the tactical information terminal is not influenced, workability in the strong light and night environments can be maintained, and adaptability of the tactical information terminal in the different battlefield environments is enhanced.

Description

technical field [0001] The invention relates to an improved ambient light adaptive method based on a tactical information terminal. Background technique [0002] With the rapid development of modern information technology, the mode of modern warfare has shifted from the traditional era of mechanized warfare to the era of informationized warfare. As an important basic unit of warfare, individual soldiers need to focus on informationized arming. The individual tactical information terminal is the end of the information tactical system in the battlefield, and it is also an important information equipment for soldiers in the field. In the operation of the whole army, it provides positioning, communication, navigation, and battlefield information collection for each combat unit. Guarantee service. [0003] Due to the diversity of changes in the battlefield environment, there are high requirements for the environmental adaptability of tactical information terminals. However, in t...

Problems solved by technology

[0006] For tactical information terminal screens, contrast and brightness are key indicators for the clear display of the screen. When we use the mobile terminal under strong light, due to the addition of strong light, the screen will reflect part of the light, and the brighter colors will basically remain unchanged. , and the original darker color brightness will be enhanced, resulting in a significant reduction in image contrast, and the image transmitted to the human eye will become blurred

Simply by adjusting the brightness of the screen, the contrast can be enhanced to a certain extent, but when the intensity of the ambient light is much higher than the maximum brightness of the screen, the effect is negligible.

[0007] On the other hand, adjusting the screen brightness to the minimum and switching the color theme to a relatively light theme in the night environment can effectively reduce the spread of light on the screen. This modification is by adding a set of night mode pictures, color and other elements, if this change is only made for one piece of software, the increased project workload is within the acceptable range, but when this solution is extended to the entire system and all the application software it carries, it will be a Unevaluable large project
