A technique for coding color components of video signals is described. In accordance with an embodiment, a color component of an image signal sequence is filtered into a plurality of subband image signals. One or more pixels of a first subband image signal are coded using one or more bits of a first quantity of bits. The first subband image signal reflects an image structure of a color component of the image signal sequence. The first subband includes low spatial and temporal frequencies of the color component. A second quantity of bits is used for coding one or more pixels of a second subband image signal. This second quantity of bits comprises one or more bits of the first quantity not used in coding pixels of the first subband image signal. One or more pixels of the second subband image signal are coded using one or more of the second quantity of bits. The second subband imagesignal reflects image object motion information of the color component of the image signal sequence. A third quantity of bits is provided for use in coding one or more pixels of a third subband image signal. The third quantity of bits comprises one or more bits not used in coding either the first or second subband image signals. One or more pixels of the third subband image signal are coded with one or more of the third quantity of bits. The third subband image signal reflects edges of moving image objects, such as horizontal or vertical edges. A corresponding method of synthesizing color images is also described.
