Abstract: A document display system includes: a plurality of display units that display an image of an electronic document including a plurality of pages for each page unit; a plurality of detecting units that detect a display operation performed by a user to each of the plurality of display units; and a control unit that controls the display unit related to the detecting unit that detects the display operation to display a page image in order of the pages corresponding to the order of detecting the display operations.

Abstract: An information processing system includes a first information processing apparatus, a second information processing apparatus, and a third information processing apparatus. The first information processing apparatus includes a collecting unit that collects information, a generating unit that generates first and second deleting conditions, an adding unit that adds the first and second deleting conditions to the information, and a first transmitting unit that transmits the information including the first and second deleting conditions added thereto. The second information processing apparatus includes a first receiving unit that receives the transmitted information, a first storing unit that stores the received information, a second transmitting unit that transmits the stored information, and a first deleting unit that deletes the information.

Abstract: An information processing apparatus includes a calculation unit, an information selection unit and an information retrieval unit. The calculation unit calculates a retrieval target level for each information based on time from when the information was stored in the past to the present. The retrieval target level for each information is used to determine as to whether or not each information is set as a retrieval target. The information selection unit selects some of the pieces of information as the retrieval targets based on the retrieval target levels calculated by the calculation unit. The information retrieval unit retrieves the some of the information selected by the information selection unit.

Abstract: A writing control system includes a display holding medium, a reading unit, an identifying unit, a control unit and a writing unit. The display holding medium includes a display section capable of displaying and holding an image in a no-power state and a storage section having a storage area for storing information that identifies an electronic document associated with it. The reading unit reads the information from the storage section when the display holding medium is located in a predetermined position. The identifying unit identifies the electronic document associated with the display holding medium, based on the information read from the display holding medium. When the electronic document associated with the display holding medium is not identified, the control unit performs control so that a page image, which has not been written, of an electronic document, which is used in last image writing, is set as a writing target.

Abstract: A writing apparatus includes: a detecting unit; a reading unit; a writing unit; a display; a first controlling unit; a second controlling unit; and a third controlling unit.

Abstract: An electronic paper system includes: electronic paper having a display unit that can display and retain an image in a no-power state; image generation means for generating a displaying image by combining a scale-down image of at least a part of a document and an image of at least part of related information of the document; and write means for writing the generated displaying image into the display unit of the electronic paper so that the display unit displays and retains the generated displaying image.

Abstract: A content management system includes a conversion a section, a display data storing section, a field section, an operation section and a management section. The conversion section converts content data into display data which is to be written into an electronic paper. The display data storing section stores the display data. The field storing section stores field data which includes identification information of a first user belonging to a field and identification information of the display data. The operation section accepts a request from a second user. The management section that allows, when the identification information of the first user contained in the field data coincides with identification information of the second user contained in the request accepted by the operation section, the display data indicated by the identification information contained in the field data to be written into the electronic paper.

Abstract: A processing apparatus includes: an operation detection unit that detects an operation; a request unit that requests other processing apparatuses to transmit functions when the operation is detected by the operation detection unit; a receiving unit that receives replies in response to the requests of the request unit from the at least one of the other processing apparatuses; a selection unit that selects at least one of the other processing apparatuses from which the receiving unit has received the replies; and a communication unit that performs communication with the at least one of the other processing apparatuses selected by the selection unit.
