1. An image display apparatus having an active-matrix display panel composed of a matrix of pixels each holding an electric signal for a predetermined period to display an image, comprising:

  • a frame-rate converter configured to convert a first video signal having a first frame frequency into a second video signal having a second frame frequency that is higher than the first frame frequency; and

    a driver configured to display an image on the active-matrix display panel according to the second video signal, the frame-rate converter including;

    an interpolation frame generator configured to generate an interpolation frame signal from frames of the first video signal;

    a multiplier configured to multiply the interpolation frame signal by a coefficient that is larger than 0 and smaller than 1; and

    an interpolator configured to interpolate the coefficient-multiplied interpolation frame signal into the first video signal and provide the second video signal.
