    • 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 (100) of the image displaying device includes a motion vector detecting portion (101) that detects motion vector information from an input image signal, an interpolation frame generating portion (106) that generates interpolation frames based on the motion vector information obtained by the motion vector detecting portion (101) and a same image detecting portion (105) 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.

    • The quality of moving picture image with a large moving amount is prevented from deterioration due to moving compensation type frame rate conversion (FRC) processing. The image display device is comprised of an FRC unit (10) that interpolates an image signal subjected to moving compensation processing between frames so as to convert the number of frames of the input image signal, a moving amount judging unit (14) that judges whether a moving amount of the input image signal between the frames is larger than a predetermined value or not, and a control unit (15). The FRC unit (10) is provided with a moving vector detecting unit (11e) that detects a moving vector between the frames of the input image signal, an interpolation vector evaluating unit (11f) that allocates an interpolation vector between the frames on the basis of the moving vector information and an interpolation frame generating unit (12d) that generates an interpolation frame from the interpolation vector. In the case where the moving amount between the frames of the input image signal is larger than the predetermined value, the control unit (15) sets the moving vector detected by the moving vector detecting unit (11e) to be zero-vector, and it invalidates the moving compensation processing of the FRC unit (10).
