First and second images (S1, S2) are separated into luminance and chrominance components to generate a first signal (Y5), in which the luminance components of the two images are sequentially located in the 1H period and a second signal (C5) in which the chrominance components of the two images are located in the same. The second signal is delayed by (1/2)H period. The first signal and the delayed second signal are used to generate a third signal (S10) in which the luminance and chrominance components of the first image are sequentially located in the 1H period and a fourth signal (S12) in which the luminance and chrominance components of the second image are located in the same. The third and fourth signals are vertically expanded with arbitrary expansion ratios. Then, the expanded signals are synthesized to generate a fifth signal (S14) in which the luminance components of the first and second images are sequentially located in the 1H period and a sixth signal (S15) in which the chrominance components of the first and second images are located in the same. The fifth signal is delayed by (1/2)H period. The sixth signal and the delayed fifth signal are interpolated to make uniform the intervals among the scanning lines. <IMAGE> |
