Patent number: 7765466Abstract: An information processing method for providing a communication terminal with a service. When editing in a lump of a plurality of held data to which the services are to be applied is received an instruction from the communication terminal, data capable of undergoing the accepted editing is automatically selected from the held data and the selected data is edited. With regard to data automatically judged to be incapable of undergoing the accepted editing, information that reports exclusion of this data from editing is transmitted to the communication terminal and is displayed thereby. That is, when plural items of held data are edited simultaneously, data not suited to this editing is excluded automatically, thereby enhancing user convenience in terms of operation. In addition, the fact that data not suited to editing has not been edited is clearly indicated to the user to prevent miss-recognition by the user.Type: GrantFiled: May 3, 2004Date of Patent: July 27, 2010Assignee: Canon Kabushiki KaishaInventor: Kohei Kawamura
