Abstract: The present invention provides a network enabled multi-user configurable optical storage server. The device is easy to install and does not require client or server software. The server can be configured across a network through a series of HTML based web pages, or graphical user interfaces (GUI) provided by the server. The server can be accessed across a network by one or more users, terminals, or other network attached devices for substantially concurrent read/write access to one or more optical storage media. The server supports a comprehensive set of networking protocols and operating systems simultaneously. The server may support from one to hundreds of CD/DVD-ROMS. In an embodiment of the invention the server includes two stages of writing prior to committing to a write to the physical medium. This speeds both read and write access to the disk, allows concurrent user access to the disk, and greatly simplifies the mapping and file structures on the disk.

Abstract: A presentation of a selected document, stored at a node of a network, is accomplished by means of a system essentially comprising a handheld device, a communication device for a presentation unit and a device that handles presentation requests. By operating the handheld device, a user is able to get a presentation unit specification from said communication device. This specification is then sent, together with an address to a selected document, to a device handling presentation requests. In this device the selected document is then converted to a format suitable for the presentation unit of said communication device, where the converted document is presented. The system could be using WAP-technology for sending information from the handheld device to the device that handles presentation requests and for accessing information on the Internet. Further the system could, for example, be using Bluetooth or IrDA for the communication between the handheld device and said communication device.

Abstract: An apparatus for storing digital images has a storage device for storing a current reference image and a plurality of differential images, and an image processing device coupled to the storage device. The image processing device receives an individual digital image, determines a difference between the individual image and the current reference image, and stores this difference as a differential image in the storage device. The apparatus also has reference image updating means for determining when to generate a new reference image, for generating the new reference image, for replacing the current reference image with the new reference image, and for storing the new reference image as current reference image in the storage device.

Abstract: A data storage and reduction method for digital images having a chronological order involves storing a first and chronologically new image or group of images at a first image quality requiring a first amount of storage space, and processing a second image or group of images, chronologically older than said first image or group of images, by reducing the image quality thereof to a second image quality requiring a second amount of storage space, which is less than said first amount of storage space. Advantageously, the method is used for a surveillance system, comprising a camera, a digital storage device and an image storage controller, wherein image quality is reduced for old or otherwise less important images or groups of images, thereby obtaining additional storage space for allowing more important images (such as images relating to an alarm event) to be stored at higher image quality, while retaining an extended total recording time span.

Abstract: A camera is disclosed which includes: at least two image sensors, an image sensor selector, a multiplexer and an image processor. The at least two image sensors are configured to synchronously output successive pixels of image data. The image sensor selector is responsive to a pan and/or tilt signal input associated with a target view of the image data provided by the at least two image sensors, to output a select signal indicating for each synchronous output of pixels from the at least two image sensors a selected one of the at least two image sensors delivering a pixel within the target view. The multiplexer has inputs, an output, and a control input. The multiplexer inputs are each coupled to a corresponding one of the at least two image sensors to receive the successive pixels of image data there from.
