它以8031单片机为基础采用硬件、软件相结合的方法实现主帧、副帧同步。

Major frame and subframe are synchronized by using the combining method of hardware and software based on 8031 microprocessor.

随后，主循环在每次循环时都检查事件、重置绘图状态、绘出圆形的“门户”窗口，然后以动画形式将其失真返回当前时帧。

Then, each pass of the main loop checks for events, resets the draw state, draws the circular "portal" windows, then animates their distortion back to the current time frame.

对于待跟踪的运动目标，采用三帧差和区域增长法分割目标并得到主颜色信息。

We used frame difference and region growing method to divide target and get main color information.
