Abstract: Disclosed is an encoder for forming electronic watermark information which allows detecting tampering of a digital content based on an electronic watermark embedded in the digital content, and limiting said tampered part. This encoder comprises means for dividing a subject digital content into multiple blocks, and means for independently forming the electronic watermark information in the individual blocks.

Abstract: The present invention provides a digital camera and a digital camera printing system applied thereon, which are possible to confirm whether there are flawed photographic images existed or not, and what kinds of the flawed photographic images they are if there are flawed photographic images existed in order to avoid wasting photographic printing paper. The digital camera printing system applied on the digital camera comprises a storing unit for storing photographic images; a determination unit for determining whether the photographic images are of flawless or flawed photographic images; and a print-out executing unit for executing print out of the photographic images stored in the storing unit, and is possible to select executions between a all-print-out mode for printing out all images which include the flawed and flawless photographic images and a list print-out for printing out a list of the flawed photographic images together with the flawless photographic images.

Abstract: A control unit of an image data management system receives image information and information regarding the image information, which are associated with each other, from an image photographing device via a communication unit, and stores the received information in a storage unit. The control unit receives an acquisition request for acquiring the image information and the information regarding the image information, which are associated with each other, from a terminal device via the communication unit, reads out the image information and the information regarding the image information, which are associated with each other and stored in the storage unit, in accordance with the acquisition request, and sends the read-out information to the terminal device which has sent the acquisition request via the communication unit.

Abstract: Disclosed are a digital camera and an image editing system capable of inputting information corresponding to each photographed image every time a photographer takes a picture, and of using the photographed images in business as they are without editing afterward.

Abstract: A control system for digital camera makes it possible to control a digital camera from a personal computer and to operate the digital camera simultaneously from both of the digital camera side and the personal computer side by means of performing a communication between the digital camera on which a WWW server function is equipped and the personal computer having a WWW browser function.

Abstract: A method of controlling TV conference communication devices having exchanges of moving picture images therebetween through a network includes sending first moving-picture-image parameters from one of the TV conference communication devices to at least another one of the TV conference communication devices during the exchanges, wherein the first moving-picture-image parameters include information indicating quality of the moving picture images, and transmitting the moving picture images from the at least another one of the TV conference communication devices by using the first moving-picture-image parameters.

Abstract: There is provided a video conference apparatus which can disconnect a communication line by a simple operation, and automatically return to a previous state when the communication line is reconnected. The video conference apparatus communicates with another video conference apparatus via a communication line so as to transmit audio and video data to permit video conferences between the apparatuses. When a temporary stop command is input, representing that the video conference currently performed is to be suspended, a present value of a parameter used for the video conference is stored. When a cancel command is input, the communication line is reconnected by using the stored value of the parameter.
