摘要： Provided is a frame rate conversion apparatus (100) for inputting a video signal and inserting an interpolation frame into the video signal so as to convert a frame rate of the video signal. The apparatus (100) includes: an input unit (1) for inputting the video signal; a video interpolation unit (2) for generating an interpolation frame and performing an interpolation process of the video signal; and a control unit (7) for controlling the generation process of the interpolation frame by the video interpolation unit (2). The video interpolation unit (2) performs the interpolation frame generation process by using a plurality of methods, and the control unit (7) controls switching between the plurality of interpolation frame generating methods.
