Abstract
In an image displaying device provided with a frame rate conversion (FRC) portion, the image quality deterioration in a moving image likely to include a plurality of the same consecutive images due to a FRC processing is prevented. The FRC portion () of the image displaying device includes a motion vector detecting portion () that detects motion vector information from an input image signal, an interpolation frame generating portion () that generates interpolation frames based on the motion vector information obtained by the motion vector detecting portion () and a same image detecting portion () that detects a case where the same images continue in the input image signal. In the case where the image of the (n−1)-th frame in the input image signal is substantially the same as the image of the n-th frame, interpolation image generating processing with the motion compensation processing made ineffective is performed between n-th frame and (n+1)-th frame to prevent that the interpolation image including a lot of errors is output.
