Abstract: In a communication system, an image forming apparatus sends an address of a receiving section to an external device. The external device receives a selection of image data through plural thumbnails displayed on a display section, and wirelessly sends the selected image data to the image forming apparatus with the address. The image forming apparatus receives the selected image data sent with the address by the external device, and prints an image based on the selected image data. The image forming apparatus accepts a selection indicating whether a communication between the external device and the image forming apparatus is performed by a first communication system method or a second communication system method.

Abstract: In a communication system, an image forming apparatus sends an address of a receiving section to a mobile terminal. The mobile terminal receives a selection of an image data among plural thumbnails displayed on a display section, and wirelessly sends the selected image data to the image forming apparatus with the address. The image forming apparatus receives the selected image data sent with the address by the mobile terminal, and prints an image based on the selected image data. A communication between the mobile terminal and the image forming apparatus is performed wirelessly with an IEEE 802.11 standard. The image forming apparatus continuously performs a second printing, when the receiving section receives a selected image data again in a condition that the communication with the mobile terminal is continuously established by the receiving section after the printing of the received image data is finished.

Abstract: An image display apparatus includes a display unit for displaying an image, a detecting unit for detecting a position designated by an operation of designating a position on the displayed image and a file operation unit operating a file. The display unit displays images generated from a file on page-by-page basis on a partial area of the display unit. The file operating unit operates the file in accordance with the change of position detected by the detecting unit, when, in a state in which no position has been detected by the detecting unit, a designated position outside of the prescribed partial area is first detected by the detecting unit and the designated position changes while the position designating operation is maintained and then no position is detected by the detecting unit. Thus, the user can easily and intuitively operate the displayed page image or the file.

Abstract: A content distribution apparatus generates a group of contents to be sent to a content display apparatus that can continuously display contents of the same attribute. When a first content is newly added to the group, the content distribution apparatus determines the attribute of the first content as the attribute of the group. When adding a second content to the group, if the attribute of the second content coincides with the attribute of the group, the content distribution apparatus adds the second content to the group. The content distribution apparatus sends a content included in the group to the content display apparatus.
