Abstract: A system includes a user terminal and a plurality of ledger nodes. The user terminal is used by an author of an item. The plurality of ledger nodes provides an electronic bulletin board. The user terminal writes an ownership right certificate including an object fingerprint of the item and biometric information of the author who is a resale royalty holder on the electronic bulletin board when the author establishes a resale royalty right on the item.

Abstract: A direction control device includes: a camera unit that acquires an image captured by photographing a subject by a camera targeted for adjustment of a photographing direction; an image-processing unit that calculates a position of a first setting image that represents the subject in the captured image; a posture detection unit that detects a difference between a position of a second setting image that represents the subject in a reference image registered in advance and the position of the first setting image; and a camera control unit that shifts the photographing direction of the camera based on the difference.

Abstract: The present invention is digital signage comprising: an article information database in which a feature of an article and article information for the article associated with each other are stored; feature extracting means for extracting a feature from a wearing image that is an image of a customer wearing an article; comparison means for comparing the extracted feature with features stored in the article information database and identifying the article the customer is wearing; article information retrieving means for retrieving article information for the identified article from the article information database; and output control means for outputting the retrieved article information and the wearing image.

Abstract: An information input/output device having an intuitive operating feeling and improved information viewing and discriminating properties. The device comprises an superposing image extraction unit 101 extracting a portion for superpositional display from an image to output the extracted image portion as an superposing image, a mask pattern generating unit 102 generating a mask pattern, effectors 113, 114 processing the superposing image, and the mask pattern based on the effect designation information, and a base image generating unit 115 synthesizing the mask pattern image and the original image to generate a base image. The device also comprises a switcher 116, brightness/contrast controllers 117, 118 adjusting the brightness or contrast of the display image switching means 112, a control unit 111, superpositional image display unit 124 for superposed demonstration of display image planes of the displays 122, 123 and a display position adjustment mechanism 121.

Abstract: A local user's location detection section 101 detects local user's location, generates location information 104 and sends the location information 104 to a local user's location discrimination section 102. The local user's location discrimination section 102 stores information on a shoot range of a camera section, judges whether the local user is in the shoot range of a camera section 602, generates notification control information 105 and sends the notification control information 105 to a notification section 103. According to the notification control information 105, the notification section 103 generates an video image 291 for notifying the local user itself whether the local user is in the shoot range of the camera section or out of the shoot range of the camera section, and sends the video image to a display section 603. If the local user is in the shoot range of the camera section, the remote user's video image 290 is sent to the display section as it is.
