The invention provides an OpenCL parallel frame rate up conversion method based on double-MIC for effectively shortening the operation time of frame rate up conversion and improving the operation efficiency of frame rate up conversion on the premise of guaranteeing the image quality. The implementation steps are as follows: a main thread initializes the MIC1 and MIC2 of an OpenCL device; the main thread numbers read videos; the main thread defines and initializes semaphore; the main thread creates a memory on a host and creates a sub-thread 1 and a sub-thread 2; the sub-thread 1 controls the MIC1 to execute a motion estimation algorithm, and meanwhile the sub-thread 2 controls the MIC2 to execute a motion compensation algorithm so as to realize the up conversion of a video frame rate; and the main thread closes the sub-thread 1 and the sub-thread 2. By adoption of the OpenCL parallel frame rate up conversion method, the operation efficiency of the algorithms is effectively improved, and the OpenCL parallel frame rate up conversion method can be used in the field of video frame rate conversion.
