Abstract
It is an object of the present invention to provide an encoding method, an encoding device, and an encoding program for encoding an interlaced image in a simple and effective manner. The encoding method includes: a frequency conversion step (s) of converting the interlaced image to coefficients of frequency domain having predetermined frequency ranges in a vertical direction and a horizontal direction, respectively; and a weighting step (s) of weighting the coefficients of frequency domain for each frequency band. In the weighting step, a weighting factor used for weighting a coefficient of a frequency band exceeding a predetermined frequency in the vertical direction is substantially equal to or larger than a weighting factor used for weighting a coefficient in a frequency band exceeding the predetermined frequency in the horizontal direction.
