Abstract: An organization process execution portion 64 is provided in a file management system 1 that has a function to manage files and search folders and a function to search files. When a search condition has been newly designated by a user, if the designated search condition does not match the search condition of any existing search folder, the organization process execution portion 64 generates a new search folder in which the designated search condition is indicated. If the designated search condition matches the search condition of an existing search folder, a new search folder is not generated.

Abstract: When thumbnails displayed indicating document files stored in a database are changed in size to “large” the thumbnails all have their respective thumbnail frames unchanged in size and the number of thumbnails displayed is also unchanged while the thumbnailed and thus displayed document files have their respective thumbnails ranges reduced and displayed under increased magnification.

Abstract: In flicker correction of a moving picture consisting of a plurality of frames, moving averages of accumulative histograms are calculated for each frame on image data. Then, gamma tables for correcting the image data of a frame in the plurality of frames are made such that the accumulative histograms after corrected with the gamma tables match with the moving averages of the accumulative histograms. Then, the image data of the frame in the plurality of frames is corrected with the gamma tables. In some cased, each frame is divided into areas, and the flicker correction is performed for each area if necessary.

Abstract: In order to track a page deleted from document data, a PC includes an HDD which stores pieces of document data each including at least one page, a selecting portion to select first document data and second document data from among the stored document data, a moving portion to move at least one of the at least one page included in the first document data into the second document data, and a move destination storing portion to store move destination information, in correspondence with the page that had been included in the first document data before a page move operation and that has been deleted therefrom and added into the second document data as a result of the page move operation, to indicate that the page that had been included in the first document data before movement of the page has been deleted from the first document data and added into the second document data.

Abstract: A file storage system that allows the user to easily designate a desired location to store a file is configured as follows. In response to a tree structure request mail from a client, a server creates a tree structure for a folder that can be accessed by the user, and describes it in a mail for reply. The user receives the mail with the description of the tree structure, designates a storage location in the form of a reply thereto, and sends a mail with an attached file to be stored to the server. Upon receiving this mail, the server stores the attached file in the designated storage location.

Abstract: In a system where files are shared by a plurality of client apparatuses through a network, when an access to a file in the shared files by a first client apparatus is received, it is decided whether the file is under editing by a second client apparatus or not, with reference to file management data. When the accessed file is not edited by a second client apparatus, the second client apparatus editing the file including a portion which the first client apparatus intends to edit, a first graphic user interface is presented for notifying whether the second apparatus permits or rejects editing of the portion by the first client apparatus. When a notification to permit editing of the portion is received, the first client apparatus is allowed to open the file in a status wherein editing of the portion is permitted.
