When determining that a pixel of a future frame, which is included in a search range, includes a pixel on an outside of an effective image area, and determining that pixels inside an effective image area of a past frame are present at positions point-symmetric to pixels inside the search range and on an outside of the effective image area about a pixel of interest, a pixel selector selects pixels in an effective image area of a past frame, the pixels being located at the point-symmetric positions. The pixel selector calculates difference values between the pixel of interest and the selected pixels inside the effective image area of the past frame.

The first frame signal is a current frame having a first number of bits. A second RGB converter is configured to place at least one lower bit of the first frame signal on the least significant bit side of a second frame signal to form composite data having the first number of bits and to convert the composite data to a second RGB signal. The second frame signal is a previous frame having a second number of bits composed of upper bits of the first number of bits other than at least one lower bit.

An image display device includes a gain calculator, a multiplier and an overdrive unit. The gain calculator calculates a ratio 'Gmax0/Gmax1' as gain, with respect to each segmented region of liquid crystal panel. The symbol 'Gmax1' represents a maximum gradation in one frame period of an image signal to be supplied to each segmented region. The symbol &#x201c;Gmax0&#x201d; represents a maximum gradation to be determined depending on the number of bits in the image signal. The multiplier multiplies an image signal subjected to frame frequency conversion in a frame frequency conversion unit by the gain to generate an image signal subjected to the area control processing, with respect to each segmented region. The overdrive unit emphasizes the image signal subjected to the area control processing, using an image signal generated by delaying the image signal subjected to the area control processing for one frame period.

A repetitive object detecting device includes data-retention and difference-calculation units, an adding unit, a horizontal direction accumulating unit and a small and large comparing unit. Each data-retention and difference-calculation unit carries out, with respect to a plurality of lines, a process for setting as reference pixel data pixel data located at an end of a plurality of pieces of pixel data, and calculating a difference between the reference pixel data and pixel data separated from the reference pixel data by k pixels (2&#x2266;k&#x2266;maximum number) to obtain difference data by each separated pixel number k. The adding unit adds the difference data in the plurality of lines by each separated pixel number k. The horizontal direction accumulating unit accumulates the added data by each separated pixel number k in a horizontal direction. The small and large comparing unit carries out a small and large comparison with respect to the horizontal accumulated value by each separated pixel number k to decide whether or not the reference pixel data is pixel data which is located in a repetitive object including a certain repetitive pattern.
