Title: Image converter, image conversion method, and recording medium
Inventor: AIDA YOICHI
IPC: H04N19/00
Filed: 2002-11-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image converter and method, and a recording medium for decoding compressed data subjected to reduction processing without the need for a frame memory having a capacity of one screen image.  <P>SOLUTION: The image converter applies reduction processing to each unit block and provides an output of a result so as to avoid the size of a work memory required for the reduction processing from being increased even when the size of an input image increases. Further, the image converter decodes and reduces compressed data by each minimum unit at the same time so as to store only a reduced and decoded image. Thus, the downsized converter, reduced cost, and saved power consumption are attained.  <P>COPYRIGHT: (C)2004,JPO
