PROBLEM TO BE SOLVED: To make an echo back speed higher in drawing by a writing brush with a density expression by using a WEB browser. SOLUTION: A drawing operation object image and an image processing program are prepared at an HTTP server 12. A terminal device 10 accesses the HTTP server 12, and downloads the drawing operation subject image. When an operator performs the drawing operation on the WEB browser screen of the terminal device 10, cursor coordinate position information and drawing radius information are sent to the HTTP server 12 by an XMLHTTP request, and image processing is carried out. The WEB browser virtually divides the drawing operation subject image into a plurality of rectangles (cells), calculates a cell in which image contents have been changed in the image processing, and issues an HTTP request for demanding the image of the cell. The HTTP server 12 cuts out and sends the processed image in the requested region. The WEB browser receives the cell image, disposes it at the corresponding region, and renews the display.
