A moving area detecting circuit detects a moving area of image information S(i-1). An intermediate image generating circuit generates intermediate image information SC(i-1) based on the moving area information. A spatial frequency separating circuit generates high-frequency image information SH(i-1) and low-frequency image information SL(i-1) from the image information S(i-1). If contrast information of the moving area is higher than a predetermined value, an image represented by the image information S(i-1) and an image represented by the intermediate image information SC(i-1) are sequentially displayed. If the contrast information is not higher than the predetermined value, an image represented by the high-frequency image information SH(i-1) and an image represented by the low-frequency image information SL(i-1) are sequentially displayed.
