Deterioration in image quality of a moving image obtained by special reproduction caused by frame rate conversion (FRC) processing of a motion compensation type is prevented. An image displaying device includes an FRC portion 10 that converts the number of frames of the input image signal by interpolating an image signal to which motion compensation processing has been performed between frames of an input image signal, a special reproduction determining portion 14 that determines whether or not the input image signal is an image signal relating to a predetermined genre, and a controlling portion 15. The FRC portion 10 includes a motion vector detecting portion lie that detects a motion vector between frames of the input image signal, an interpolation vector evaluating portion 11f that assigns an interpolation vector between frames based on the motion vector information, and an interpolation frame generating portion 12d that generates an interpolation frame from the interpolation vector. When the input image signal is an image signal obtained by special reproduction including “fast forward reproduction” and “rewind reproduction”, the controlling portion 15 makes the motion compensation processing in the FRC portion 10 ineffective by making the motion vector detected by the motion vector detecting portion 11e to zero-vector.
