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。 Video electronic sub-sight sights have been designed. According to the principle of electronic image superimposition, the electronic dividing line of the screen storage mapping method and the operation prompt field are completed. The core of the system is composed of single-chip microcomputer, video overlay display chip, digital potentiometer and monostable delay circuit, with overlay image and scene image display, manual two-dimensional adjustment aimed at the dividing line position and OLED brightness contrast, Sexual conversion and manual non-uniform correction and other functions.
