Abstract
The invention is directed to a method and apparatus for transforming the dimensions of an image represented by block-interleaved data. The method comprises: (a) storing a first minimum coded unit of the image data in a first memory; (b) dimensionally transforming the first minimum coded unit; and (c) storing a second minimum coded unit of the image data in the first memory. Steps (b) and (c) are performed after step (a). In addition, step (b) is performed before: starting to store any third minimum coded unit in the memory after step (c). The apparatus comprises a first memory, a storing circuit, a dimensional transforming circuit, and a timing control circuit. Preferably, the first memory is sized for storing no more than two minimum coded units.
