1. An apparatus for processing a non-interlaced image, comprising: a processor coupled to a memory; a wavelet transform unit to perform a two-dimensional discrete wavelet transform of a level higher than or equal to level one on data of the non-interlaced image; a determination unit to determine a movement speed of an object within the non-interlaced image based on at least values of wavelet coefficients of a 1LH sub-band of wavelet coefficients obtained by the wavelet transform unit and values of wavelet coefficients of another sub-band, wherein the determination unit calculates a ratio of the values of the wavelet coefficients of the 1LH sub-band and the values of the wavelet coefficients of the another sub-band; and a data reduction unit to reduce the data of the non-interlaced image based on a result of the determination of the determination unit.
