Abstract
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 portionthat 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 portionthat determines whether or not the input image signal is an image signal relating to a predetermined genre, and a controlling portion. The FRC portionincludes a motion vector detecting portion lie that detects a motion vector between frames of the input image signal, an interpolation vector evaluating portionthat assigns an interpolation vector between frames based on the motion vector information, and an interpolation frame generating portionthat 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 portionmakes the motion compensation processing in the FRC portionineffective by making the motion vector detected by the motion vector detecting portionto zero-vector.
