A system comprising cascaded standardized hot-pluggable transceiving units for providing scaling and positioning functionalities. A first layer comprises a plurality of transceiving units implementing a scaling functionality followed by a pre-positioning functionality. A second layer comprises a transceiving unit implementing a scaling functionality followed by a positioning functionality. Source video streams are scaled by the first layer, and further combined to generate primary mosaiced video streams. The primary mosaiced video streams are scaled and combined by the second layer to generate a secondary mosaiced video stream. Alternatively, the first layer comprises at least one transceiving unit only implementing the scaling functionality. Source video streams are scaled by the first layer to generate primary scaled video streams. The primary scaled video streams are scaled and combined by the second layer to generate a mosaiced video stream.

A system and method for communicating a multimedia presentation between a presenter and an audience is described. Services provided via a network facilitate the communication, and include real-time determination of remaining portions of a presentation responsive to on the fly presentation modifications, automated filtering and prioritization of audience feedback to a presenter, and integration with one or more customer data resources.

A device, system and method for automatic calibration of image devices is provided. Triplets of at least three image devices, including a projector, are in non-collinear arrangements, and pairs of the image devices have overlapping fields of view on a physical object. Pixel correspondences between the pairs are used to determine relative vectors between the image devices. Relative locations between each of the image devices are determined based on the relative vectors with a relative distance between one pair of the image devices is to an arbitrary distance, the relative locations being further relative to a cloud-of-points representing the object. A model of the object and the cloud-of-points are aligned to transform the relative locations of each of the image devices to locations relative to the model. The projector is controlled to project onto the object based at least on the locations relative to the model.

The invention has an object to provide a display device that enables a user to obtain information from a projection image without losing information obtained from the surrounding environment.

The display device is to be mounted on a head of the user for allowing the user to view a predetermined image, and includes a light quantity detector (17) to detect a quantity of external light; a laser (211R, 211G, 211B) to emit a laser light having a light quantity depending on a current value; a light attenuator (22) including filters to switch an attenuation ratio so as to attenuate the laser light; an optical scanner (15) to scan the laser light transmitted through the filter; an optical projection system (16) to project the scanned laser light to form an image; and a controller (27) to control brightness of the image by increasing or decreasing the current value and by switching the attenuation ratio of the filter, based on the light quantity of the external light detected by the light quantity detector.

A display where water is applied onto the screen of a visual display monitor and graphics are presented on the display that coincides with the applied water is described. The timing of the water being applied to the screen and the playing of the graphics may be orchestrated such that the applied water seems to create the presented graphics. A controller may be used to control the water and the display.

A wide angle image to be displayed on a screen fixed on the head or the face of a user is processed. When a display view angle reaches a boundary of an original wide angle image 701, an indicator 703 indicating reaching the boundary is added to a free viewpoint image 702. The indicator 703 is apart of the free viewpoint image 702 which is in contact with a boundary 704 of the wide angle image 701 or protrudes from the boundary 704 and is displayed as a black-painted frame. By observing such the indicator 703, the user can intuitively understand that the display area reaches the limit of the wide angle image.

[Object] To process an image captured by a camera mounted on a moving object device or a user to be suitable for display on an image display device fixed to the head or face of the user. [Solution] The image rendering processor 1042, in the beginning, corrects the user's head posture angle q.sub.h using the camera posture angle q.sub.c (F1421), and clips a display angle of view depending on the corrected user's head posture angle q.sub.h* from the captured image to render a free viewpoint image (F1422). Then, the image processing device 1040 transmits the free viewpoint image rendered by the image rendering processor 1042 to the display device 1020 via the communication unit 1041, and the image is displayed on the display device 1020 (F1430).
