Abstract: A distribution management apparatus includes a generator configured to generate still-picture data from content data, a converter configured to convert the still-picture data into video data, and a distributer configured to distribute the video data to each of a first communication terminal and a second communication terminal, which are capable of playing back and displaying the video data. When first operation data indicating an operation of zooming into a partial region of the video data being played back and displayed on the first communication terminal is transmitted, the converter generates video data representing a partial region, which depends on display/playback capabilities of the second communication terminal, of the video data being played back and displayed on the first communication terminal, and the distributer distributes the video data representing the partial region generated by the converter to the second communication terminal.

Abstract: A distribution management apparatus includes an acquisition unit that acquires terminal management information that indicates locations of multiple communication terminals, a determination unit that determines cutout position information of video data based on the terminal management information acquired by the acquisition unit and operation data received from any one of the communication terminals, a cutout unit that cuts out multiple pieces of video data from the video data based on the cutout position information determined by the determination unit, and a distribution unit that distributes the video data cut out by the cutout unit to each of the communication terminals based on the terminal management information. The determination unit modifies the cutout position information of the video data based on the operation data.

Abstract: A distribution management apparatus includes: a receiving unit that receives operation information, which indicates operation input that a terminal has accepted, from the terminal via a network; a browser that creates drawing information to be displayed on the terminal from the operation information; an encoder that encodes the drawing information; and a transmitting unit that transmits the encoded drawing information to the terminal.

Abstract: In a video teleconference device, a microphone and a speaker are arranged in a housing in such a manner that a voice input direction of the microphone and a voice output direction of the speaker are roughly orthogonal to each other. With that, the sound coming out of the speaker is not easily received as input by the microphone. Thus, with such a simple configuration, it becomes possible to effectively curb the echo effect and the howling effect.

Abstract: An input image is analyzed into document components. Preview data of the input image is generated based on a result of analysis. A function item that can be processed on the input image is selected based on the result of analysis. A function item is specified from among function items displayed on an operation display unit. A target area for specified function item is displayed together with the preview data on the operation display unit. A target area is specified from among target areas displayed on the operation display unit. New preview data that reflects the specified function item processed on specified target area is generated, and output to the operation display unit.

Abstract: An image processing apparatus includes a camera, a support body, and an arm section including an arm that is rotatably attached to the support body and to a camera housing incorporating therein the camera. The image processing apparatus calculates a height of the camera measured from a set surface, using dimensional information of the image processing apparatus and inclination information indicating an inclination of the camera and an inclination of the arm. The image processing apparatus specifies a type of an object subjected for capturing by the camera using at least the height of the camera, and applies image processing specific to the specified type of the object to a captured image captured by the camera.

Abstract: An image processing apparatus includes a system control unit, and a display control unit. The system control unit judges whether a setting item that is newly selected on a preview image is mutually exclusive with a setting item that has already been selected on the preview image. The display control unit displays, when the setting items are mutually exclusive with each other, an area corresponding to the setting item newly selected differently from other areas. The display control unit also displays, when the area is selected, why the setting item newly selected cannot be set.

Abstract: The image data processing apparatus includes a storage unit to store image data having a process setting. The image data processing apparatus includes a selection screen display unit to display the one or more image data stored in the storage unit and to display a selection screen to select whether to use a process content associated with image data selected from the displayed image data if the one segment of image data is used. The image data processing apparatus includes a display control unit to display, on the display device, a preview image reflecting the process content based on the associated process content.

Abstract: An analyzing unit analyzes components of input information. An area generating unit generates information on an area-representing image. A preview generating unit generates information on a preview in which the area-representing images are overlapped for each page. An operation display unit displays the information on the preview and information on a function to be performed, and accepts an instruction for setting the function. Upon accepting the instruction for the function, the preview generating unit further generates information on a preview with a processing according to the instruction performed.
