  • Patent number: 6320981
    Abstract: Block representative values are set adaptively based on the feature amount concerning the distribution state of a prepared histogram of input image data. Thus, if block truncation coding is executed based on an input image having mixed CG image and scanned image areas, efficient coding can be performed and a high-quality decomposed image can be provided. Further, when the histogram is divided into image data groups, the image data groups can be again divided to provide a high-quality decomposed image, thus efficient coding can be performed and a high-quality decomposed image can be provided more reliably.

  • Patent number: 6310694
    Abstract: A mail transmission/reception system, in which a user on the transmitting end, who wishes to revise or delete a print mail mistakenly sent to a remote user, can transmit a cancel mail to the destination address of the same remote user to have the specified print mail deleted on the remote user's computer system in S690, thereby preventing the print mail from being printed on the remote user's end. Also, the user on the transmitting end can know whether the printing has been prevented based on mail returned from the remote user in S660-S680 and can take appropriate measures when the mail cancellation has not been successful.
