20100007750 | VIDEO OVER ETHERNET - The present invention relates to a network enabled digital video camera arranged to be connected to a digital network. The network enabled digital video camera includes a digital network module arranged to transmit and receive digital signals, an input/output port being an electrical connector and being connected to the digital network module, and an analog video generator arranged to output an analog video signal. The input/output port connected to the digital network module is also connected to the analog video generator. The present invention also relates to an adaptor used to connect the network enabled digital video camera to an off-the-shelf video preview device. | 01-14-2010 |
20090259747 | INFORMATION COLLECTING SYSTEM - A method for connecting a storage device to an information generating device includes transferring an identifying message from the storage device to a control server via a computer network. The identifying message includes a unique identifier uniquely identifying the storage device, matching a registered information generating system to the unique identifier, and identifying at least one information generating device included in the matched information generating system. A configuration message is transferred from the control server to the storage device, and the configuration message includes an address to the identified at least one information generating device and instructions of interaction. The instructions of interaction are arranged to define how the transfer of generated information is to be performed. | 10-15-2009 |
20090141143 | NETWORK CAMERA - The invention relates to a network camera comprising an image acquisition part, an image processing part, a flat cable connecting the image acquisition part with a first end of the image processing part, and an inlet for an external data cable arranged at a second end of the image processing part. The image acquisition part is tiltable around a first axis in relation to the image processing part, the image processing part and the image acquisition part in combination are rotatable around a second axis, and the first and second axes are essentially perpendicular to each other. | 06-04-2009 |
20090091941 | PANEL COMPONENT HOLDER - The invention relates to a panel component holder arranged to be attached to a panel element. The panel component holder comprises at least one supporting means and a casing including a brim and at least one retainer. The at least one supporting means comprises an attached end being attached to the casing, an elastic means and a free end. Said at least one retainer is arranged to prevent outwardly movement of the at least one supporting means from said casing in a plane coinciding with the centre axis of the casing, wherein the outwardly movement of the supporting means is induced by the elastic means. | 04-09-2009 |
20080259159 | SUPPORTING CONTINUOUS PAN ROTATION IN A PAN-TILT CAMERA - The invention relates to a method for moving a maneuverable part of a pan-tilt camera from a first pan-tilt position, having a first pan coordinate and a first tilt coordinate, to a second pan-tilt position, having a second pan coordinate and a second tilt coordinate. The maneuverable part is moved by inverting the maneuverable part of the camera and panning to the second pan coordinate. The first pan coordinate is part of a pan-tilt coordinate system and the second pan coordinate is part of a complementary pan-tilt coordinate system, which represents positions of the inverted maneuverable part. The maneuverable part is moved from the first tilt coordinate to the second tilt coordinate. The first tilt coordinate is part of the pan-tilt coordinate system and the second tilt coordinate is part of the complementary pan-tilt coordinate system. The invention also relates to a corresponding device and a corresponding computer program. | 10-23-2008 |
20080204560 | METHOD FOR COMPENSATING HARDWARE MISALIGNMENTS IN A CAMERA - A method for compensating hardware misalignments in a camera is presented. The camera includes a maneuverable part and a fixed part, and the maneuverable part is controlled by a steering motor system. In a first step of the method mechanical coordinates from the steering motor system is received, wherein the mechanical coordinates correspond to a pan and tilt position, the pan and tilt position having a complementary pan and tilt position. Next, pre-determined calibration data corresponding to the received mechanical coordinates is read from a memory wherein the pre-determined calibration data describes a relationship between a pan and tilt position and a complementry pan and tilt position, and then compensated coordinates are determined based upon the received mechanical coordinates and the pre-determined calibration data. | 08-28-2008 |

20080198178 | PROVIDING AREA ZOOM FUNCTIONALITY FOR A CAMERA - The invention relates to a method for adjusting a digital camera. The invention also relates to a corresponding device and a corresponding computer program. An original image recorded by the camera is received. The original image has an original aspect ratio. A first user input defining a center point of an area of interest within the original image is received. A second user input defining a perimeter for the area of interest of the original image is received. The perimeter for the area of interest has the same aspect ratio as the original aspect ratio. The camera view is adjusted based on the first user input and the second user input to provide a zoomed image of the defined area of interest. The zoomed image is centered on the center point defined by the first user input. Finally, the zoomed image is displayed to the user on a display screen. | 08-21-2008 |
