中文摘要：

为了解决当帧率上变换算法遇见超高清电影模式序列时,由于重复帧导致运动矢量场无法收敛到真实轨迹,设计了一种高效率的电影模式检测与实现的方法.将视频图像进行分块不规则采样,对各个子块进行像素直方图统计,根据统计结果来进行电影模式处理,最后经过FPGA硬件验证及RC综合.实验结果证明,该算法设计在实时处理50/60 Hz超高清序列大数据流量时仅需很小的存储器资源,并且可以快捷准确地对电影模式进行实时检测处理,特别是局部运动的序列检测.

英文摘要：

In order to solve the problem of motion vector field unable to converge to the real movement trace, as repeated frames, when meet a sequence of UHD film mode in the algorithm of the frame rate conversion, the high efficient way of implementation and design of film mode detection is designed in this paper. The video sequences are divided into many blocks, which are irregular sampling, for each block through building pixels histogram to perform film mode detection, then the film mode function to be triggered according to the film mode detection results. Meanwhile, the verification and implementation are also processed based on FPGA and RC. The results prove that the algorithm of design has very small storage resources, and can accurately verify the film mode, when it process big data, such as 50/60 Hz UHDTV, especially for the sequential of local movement.
