| 20090058984 | MOBILE COMMUNICATION TERMINAL AND METHOD FOR CONVERTING MODE OF MULTIPARTY VIDEO CALL THEREOF - A mobile communication terminal having a multiparty video call function and a method for converting a mode of a multiparty video call are disclosed. The terminal includes an input unit that receives a command for selecting one of phone call modes and a controller that displays a menu for selecting a phone call mode on the display, when a request for a video call or video chatting with the third terminal is wirelessly transmitted or received while the mobile communication terminal is performing video call communication or video chatting, and maintains an established call mode or converts the established call mode to a different phone call mode according to a phone call mode selected through the input unit to perform multiparty video call communication. | 2009-03-05 |
| 20090058985 | SYSTEM AND METHOD OF AUTOMATING ACCESS TO A VIDEOCONFERENCING ROOM - A videoconferencing system and method of automating access to a videoconferencing room is provided. The videoconferencing system includes a reservation controller for comparing remote identifying information and local identifying information and for receiving a deposit. A payment collector is in communication with the reservation controller for receiving the deposit from the reservation controller. An access controller is in communication with the payment collector and the reservation controller for allowing access to the videoconferencing room if the remote identifying information matches the local identifying information. The method includes the steps of receiving remote identifying information, receiving local identifying information, comparing the local identifying information to the remote identifying information, and electronically unlocking a door of the videoconferencing room if the local identifying information matches the remote identifying information. | 2009-03-05 |
| 20090058986 | Measuring latency in a video conference system - A method of measuring video latency between a sender and a receiver in a video conference system is disclosed. In an embodiment, the method includes initiating an electrical signal from a first location in a video conference system, transmitting the electrical signal through the video components of the video conference system, reflecting the electrical signal back through the video components of the video conference system and measuring the latency of the electrical signal at the first location related to the transmission and reflection of the electrical signal. | 2009-03-05 |
| 20090058987 | Video camera calibration system and method - A video camera calibration system includes a video camera, having a fixed location and a variable viewing orientation with respect to a fixed object, and a video calibration target, integral with the fixed object and having a known position. The viewing orientation of the video camera can be adjusted by aligning the position of the video calibration target in a video image produced by the video camera. | 2009-03-05 |
| 20090058988 | System for Panoramic Image Processing - A system for low-latency, high-resolution, continuous motion panoramic video imaging includes a plurality of high-resolution video cameras, each video camera generating about at least 500 kilopixel near-real time video. The cameras can be supported for positioning the plurality of cameras at predetermined angular locations to generate a full 360 degree field of view. The system can also include an image processor for processing video image signals in parallel and providing panoramic images. In one embodiment, the system can include a display to provide seamless panoramic images. | 2009-03-05 |
| 20090058989 | Method and apparatus for obtaining improved panoramic images - A digital photographing apparatus capable of more precisely obtaining a panoramic image than conventional cameras, a method of controlling the digital photographing apparatus, and a recording medium storing a program for executing the method. The method of controlling a digital photographing apparatus includes: obtaining a first image according to a user's signal; inverting the pixel values of a portion of the first image; obtaining a second image; and obtaining a third image by combining the first image and the second image. | 2009-03-05 |
