description The invention discloses a method and device for generating a video interpolation frame, relating to video processing. The method comprises the following steps: detecting whether the brightness of the current frame is changed abruptly relative to the previous frame by calculating the difference of the average brightness value of the current frame and the average brightness value of the previous frame image; if so, selecting to copy the current frame or the previous frame as an interpolation output frame, otherwise, searching the motion vector of the interpolation frame corresponding to each subblock through bilateral movement of block matching; and then filtering the motion vector, and generating a movement compensation interpolation frame serving as the interpolation output frame according to the motion vector. According to the invention, large arithmetic amount caused by a great deal of errors during the movement searching of the two adjacent frames with relatively larger brightness difference is avoided, an
