<p><P>PROBLEM TO BE SOLVED: To provide a scroll display method with which a user response during the scroll display of image data can be improved by reducing communication traffic between a server and a client. <P>SOLUTION: A portion of coded data stored in a server is fragmentarily received through a network, and the fragmentary coded data are cached. Then, only the cached coded data are decoded during the scroll operation, and decoded image data are displayed so as to be enlarged. After the scroll operation of the cached coded data is ended, the coded data are decoded with higher resolution and higher layer than the previous time, and the decoded image data are displayed so as to be enlarged. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
