Abstract

The present invention makes it possible to process at high speed the foreground component image and the background component image of picked up images on a network platform. A client computeroutputs information specifying image data desired to separate to a separation server. The separation serverobtains the specified image data from a storage serverand outputs it to a motion detecting serverto perform motion detection processing. Thereafter, the image data, motion vector and positional information are output to an area specifying server. The area specifying servergenerates area information of the image data and outputs the area information to a mixture ratio calculating serverin addition to the image data, the motion vector and the positional information. The mixture ratio calculating servercalculates a mixture ratio on the basis of the image data, the motion vector, the positional information and the area information, and a foreground/background image separation serverseparates foreground and background of the input image on the basis of such information. The present invention may be employed in a business model for image processing.
