Abstract

A multiple-site drawn-image sharing apparatus is disclosed that causes images drawn on drawing objects provided at multiple sites to be shared between the drawing objects. The apparatus includes an image storage unit configured to store the images drawn at the respective sites; an image synthesizing unit configured to superimpose and synthesize the images stored in the image storage unit in a manner so as not to include the images drawn at transmission destinations; and an image transmission unit configured to transmit the images synthesized by the image synthesizing unit to the respective sites.

Claims (13)

  1. Claim 1. A multiple-site drawn-image sharing apparatus that causes images drawn on drawing objects provided at multiple sites to be shared between the drawing objects, the apparatus comprising:

    an image storage unit configured to store the images drawn at the respective sites;
    an image synthesizing unit configured to superimpose and synthesize the images stored in the image storage unit in a manner so as not to include the images drawn at transmission destinations; and an image transmission unit configured to transmit the images synthesized by the image synthesizing unit to the respective sites.
  2. Claim 2. The multiple-site drawn-image sharing apparatus according to claim 1, wherein the image synthesizing unit generates synthesized images by superimposing a position of an image drawn at a first site on positions of images drawn at sites other than the first site.
  3. Claim 3. The multiple-site drawn-image sharing apparatus according to claim 2, wherein the image synthesizing unit generates the synthesized images by replacing with a minimum value a pixel luminance value at a same position of the image drawn at the first site and the images drawn at the sites other than the first site.
  4. Claim 4. The multiple-site drawn-image sharing apparatus according to any one of claims 1 through 3, the apparatus further comprising:

    a latest image buffer configured to store latest images drawn at the respective sites.
  5. Claim 5. The multiple-site drawing-image sharing apparatus according to any one of claims 1 through 4, wherein the image synthesizing unit specifies the image drawn at the first site stored in the latest image buffer to synthesize the images other than the image drawn at the first site stored in the latest image buffer.
  6. Claim 6. The multiple-site drawing-image sharing apparatus according to any one of claims 1 through 4, wherein the image synthesizing unit integrates the images received from all the sites to generate an integrated image, and generates difference images between the integrated image and the images stored in the latest image buffer to thereby generate the synthesized images.
  7. Claim 7. The multiple-site drawing-image sharing apparatus according to any one of claims 1 through 6, the apparatus further comprising:

    an image synthesizing method determination unit configured to determine a synthesizing method of the image synthesizing unit based on a number of the sites and image quality.
  8. Claim 8. The multiple-site drawing-image sharing apparatus according to any one of claims 1 through 7, wherein the image transmission unit transmits the synthesized images to the respective sites at a time at which the synthesized images of all the sites to be transmitted are generated.
  9. Claim 9. The multiple-site drawing-image sharing apparatus according to any one of claims 1 through 7, wherein the image transmission unit sequentially transmits the synthesized images to the respective sites when the synthesized images to be transmitted are generated.
  10. Claim 10. The multiple-site drawing-image sharing apparatus according to any one of claims 1 through 7, wherein the image transmission unit transmits the synthesized images to the respective sites when a certain time elapses since starting of image synthesizing processing.
  11. Claim 11. The multiple-site drawing-image sharing apparatus according to claim 10, wherein the image synthesizing unit generates, if the synthesized images of all the sites are not generated when the certain time elapses since the starting of the image synthesizing processing, the synthesized images using latest images previously stored in the latest image buffer, and the image transmission unit transmits the synthesized images.
  12. Claim 12. A multiple-site drawn-image sharing system having a multiple-site drawn-image sharing apparatus that causes images drawn on drawing objects provided at multiple sites to be shared between the drawing objects and having clients that extract only information drawn at own sites from the images drawn on the drawing objects, the multiple-site drawn-image sharing apparatus comprising:

    an image storage unit configured to store the images drawn at the respective sites;
    an image synthesizing unit configured to superimpose and synthesize the images stored in the image storage unit in a manner so as not to include the images drawn at transmission destinations; and an image transmission unit configured to transmit the images synthesized by the image synthesizing unit to the respective sites.
  13. Claim 13. A method executed by a multiple-site drawn-image sharing apparatus that causes drawn images drawn at two or more remote sites to be shared, the method comprising:

    storing the images drawn at the respective sites;

    superimposing and synthesizing the stored images in a manner so as not to include the images drawn at transmission destinations;
    and transmitting the synthesized images to the respective sites.
