It is an object to prevent the
image quality deterioration of a moving image likely to include a plurality of the same consecutive images such as a movie video and an
animation video due to the motion-compensated
frame rate conversion (FRC)
processing. An image displaying device is provided with an FRC portion (10) for converting the number of frames in an input
image signal by interpolating an
image signal to which a motion compensation
processing has been given between the frames in the input
image signal, a genre determining portion (14) for determining whether the input image
signal is a predetermined genre, and a controlling portion (15). The FRC portion (10) includes a
motion vector detecting portion (11e) for detecting a
motion vector between the frames of the input image
signal, an interpolating vector evaluating portion (11f) for allocating an interpolating vector between the frames based on the
motion vector information, and an interpolating frame generating portion (102) for generating an interpolating frame from the interpolating vector. In the case that the input image
signal is relating to a movie or
animation, the control portion (15) set the motion vector detected by the motion vector detecting portion (11e) to zero-vector to make the motion compensation
processing of the FRC portion (10) ineffective.
