Abstract
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 2-3 or 2-2 pulldown video due to the motion-compensated frame rate conversion (FRC) processing. An image displaying device is provided with an FRC portion () 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 pulldown detecting portion () for detecting whether the input image signal is an image signal to which pulldown conversion has been performed, and a controlling portion (). The FRC portion () includes a motion vector detecting portion () for detecting a motion vector between the frames of the input image signal, an interpolating vector evaluating portion () for allocating an interpolating vector between the frames based on the motion vector information, and an interpolating frame generating portion () for generating an interpolating frame from the interpolating vector. In the case that the input image signal is an image signal to which pulldown conversion has been performed, the controlling portion () set the motion vector detected by the motion vector detecting portion () to zero-vector to make the motion compensation processing of the FRC portion () ineffective.
