Abstract
A picture coding method includes the steps of translating the data of an image into 3-dimensional blocks and detecting their movements, in which the transform coefficients of a high degree in the space associated with the 3-dimensional blocks where more movement is involved are removed for reducing spatial resolution while maintaining time resolution and also, the transform coefficients of a high degree in the time associated with the 3-dimensional blocks where less movement is involved are removed for reducing time resolution while maintaining spatial resolution, so that the effective compression of the data can be implemented without a great visual degradation in the picture quality.
