The 3CCD Progressive Scan camera is the latest of WolfVision's own developments and uses a beam splitter that divides each pixel into the separate red, green and blue primary colours. This ensures there is a CCD for each colour unlike a 1CCD camera in which four pixels are needed to create the colour. As a result the image enjoys much higher resolution and perfect colours.
Both the VZ-57plus and VZ-C30 use WolfVision's patented Synchronised Lightfield in which the illuminated part of the working surface is always identical to the pick up area of the camera. Objects are, therefore, easy-to-position and manoeuvre as they are simply placed in the illuminated area. The models' Image Turn function ensure 90% of the cameras' effective pixels are used to reproduce vertical A4 documents resulting in 40% higher resolution. Four output modes - UXGA, SXGA, XGA and SVGA - are offered on the new WolfVision models. The units' Auto Resolution function recognises the mode of the connected projector or monitor and automatically selects the relevant output mode.
A full set of connectivity options is provided among them USB 2.0, LAN and RS232.The USB 2.0 connection transfers images to a computer for saving in JPEG; TIF or BMP formats allowing the systems to be used as scanners for 3-dimensional objects. Working under Windows 98, ME, 2000, XP and Apple Macintosh, the USB software is fully Twain compatible and is ideal for use with popular graphic programmes such as PhotoShop; or for connecting to interactive whiteboards; it can also present live images.
The models' 10/100Mbps Ethernet (LAN) port, being IP addressable, allows the Visualizers to act as network devices that can be integrated into and controlled over enterprise networks or the Internet. In conjunction with videoconferencing systems, the Visualizer display can be seen and controlled from remote locations.
