    • The synchronous optical pen electronic whiteboard system in the present invention introduces an image sensor with a global shutter, optical pen pulsing light-emission and synchronizing signal transmitter and receiver. The light pulsing of the optical pen and the exposure of the image sensor coincide by synchronizing signal so as to realize the object of increasing signal-to-noise-ratio. A synchronizing signal sender can be arranged in the optical pen and a synchronizing signal receiver arranged in a signal receiving device, or a synchronizing signal sender can be arranged in the signal receiving device and a synchronizing signal receiver arranged in the optical pen. The coincidence of light pulsing and the exposure can be realized in the two solutions, thereby realizing the object of the present invention. By using the solution of the present invention, the power consumption of the optical pen can be reduced effectively and the signal to noise ratio of the system can be effectively increased in the meanwhile.
    • 本发明的同步光笔电子白板系统引入了具有全局快门,光笔脉冲发光和同步信号发送器和接收器的图像传感器。 光笔的光脉冲和图像传感器的曝光与同步信号重合,以实现提高信噪比的目的。 同步信号发送器可以布置在光笔中,并且布置在信号接收装置中的同步信号接收器或同步信号发送器可以被布置在信号接收装置中,并且配置在光笔中的同步信号接收器。 可以在两种解决方案中实现光脉冲和曝光的一致性,从而实现本发明的目的。 通过使用本发明的方案,能够有效地降低光笔的功耗,同时可以有效提高系统的信噪比。
