Abstract: A drawing object image and an image processing program are provided in an HTTP server 12. The drawing object image is downloaded by accessing the HTTP server 12 from a terminal unit 10. When the operator initiates a drawing operation on a WEB browser screen of terminal unit 10, an XMLHTTP request with coordinate position information of the cursor and the drawing radius information are transmitted to the HTTP server 12 to execute an image manipulation process. The WEB browser virtually divides the drawing operation object image into cells, identifies the cells in which the image contents are modified in the image manipulation process, and issues HTTP requests for the cell images. The HTTP server 12 cuts out the manipulated image in the requested areas and transmits them to the WEB browser and arranges them.

Abstract: To make the echo back faster in operating the drawing by means of a brush tool having a density representation using a WEB browser. A drawing operation object image and an image processing program are prepared in an HTTP server 12. The drawing operation object image is downloaded by accessing to the HTTP server 12 from a terminal unit 10. When the operator makes a drawing operation on a WEB browser screen of the terminal unit 10, an XMLHTTP request with the coordinate position information of the cursor and the drawing radius information are transmitted to the HTTP server 12 to execute an image manipulation process. The WEB browser virtually divides the drawing operation object image into plural rectangles (cells), computes to identify the cells in which the image contents are modified in the image manipulation process, and issues HTTP requests for the cell images. The HTTP server 12 cuts out the manipulated image in the requested areas and transmits them.

Abstract: The present invention provides an image display method for downloading an image of large longitudinal and transverse size and displaying it on a viewer with less latency time. The image display method may be used to divide an image larger than a display region of a viewer into a plurality of areas where each divided image is provided beforehand in a server. The viewer determines the plural divided images of which at least a part of each is contained in the display region of the viewer in accordance with a relative position between the image and the display region of the viewer and makes a preferential request of the viewer for the divided images. The viewer rearranges and displays the received divided images in their original form.

Abstract: An object of the present invention is to provide an image display method for downloading an image of large longitudinal and transverse size and displaying it on a viewer with less latency time. This image display method includes dividing an image larger than a display region of a viewer 12 into a plurality of areas longitudinally and transversely, each divided image being provided beforehand in a server. The viewer 12 determines plural divided images at least a part of each of which is contained in the display region of the viewer 12 in accordance with a relative position between the image and the display region of the viewer 12, and makes a preferential request to the server 10 for the divided images. The server 10 preferentially transmits the corresponding divided images in response to the request. The viewer 12 rearranges and displays the received divided images in an original state.
