一种适合视频瞄准具的电子分划叠加电路系统

对视频电子分划瞄准具进行了设计。根据视频图像电子叠加原理,完成了屏幕存储映射方式的电子分划线及操作提示符场叠加。系统核心是由单片机、视频叠加显示芯片、数字电位器和单稳态延时电路组成,具有叠加图像与场景图像同显、手动二维调节瞄准分划线位置及改变OLED亮度对比度、热图极性转换和手动非均匀校正等功能。

Electronic aim line compound circuit system for video collimation equipment

The system of electronic video equipment for collimation is designed in the principle of image compounding. Accomplished that electronic aim line and prompts can display in a field, which is used as way of screen storage mapping. The system core includes SCM main driver, OSDC, digital resistance, monostable circuit. It can achieve the functions such as displaying compound image and scene synchronously, moving aim line 2-D manually, adjusting OLED lightness or contrast, switching polarity of thermal image, emendation non-uniformity and so on.
