摘要： A single-projection widescreen projecting device includes an image processing system and in turns in the direction of light path an optical non-imaging system providing a light source; an optical imaging system; a light path switching system; and a projecting lens which projects a magnified image onto a screen. The image processing system connects the optical imaging system to the light path switching system and is used to divide the image into N frames of small images and then transmit the small images to the optical imaging system. N is natural numeral greater than 1. At the moment of transmitting the small images to the optical imaging system, a corner signal corresponding to each frame of the small images is transmitted the light path switching system. The optical imaging system is used to receive N frames of the small images and light rays from the optical non-imaging system and then display the N frames of the small images after the light rays of the optical non-imaging system are adjusted. The light path switching system includes a mirror and a rotary motor. The rotary motor is used to receive the corner signal to control the rotating angle of the mirror. This invention uses a single-projection technology to achieve the widescreen projection with superior frame display ratio to the current art.
摘要翻译：单投影宽屏投影设备包括图像处理系统，并且在光路的方向上依次提供提供光源的光学非成像系统; 光学成像系统; 光路切换系统; 以及将放大图像投影到屏幕上的投影透镜。图像处理系统将光学成像系统连接到光路切换系统，并用于将图像划分成N帧的小图像，然后将小图像发送到光学成像系统。 N是大于1的自然数。在将小图像发送到光学成像系统的时刻，与小图像的每个帧对应的角信号被传送到光路交换系统。光学成像系统用于从光学非成像系统接收N帧的小图像和光线，然后在光学非成像系统的光线被调整之后显示小图像的N帧。光路切换系统包括反光镜和旋转马达。旋转电机用于接收转角信号以控制反射镜的旋转角度。本发明使用单投影技术来实现与现有技术相比具有优异的帧显示比的宽屏投影。
