Projection Technology

Article excerpt

Projection devices were among the first forms of technology to make their way into the educational setting. Years of usage have not diminished their usefulness. These devices have kept pace with other new technologies, remaining an integral part of instruction at all levels. New features and improvements have, if anything, increased their role in education.

Following are some cutting-edge projection devices for education. We think you'll find that these are not your father's projectors.

Canon's Multimedia Projector LV-7525 has a brightness of 2,750 ANSI lumens, and is equipped with a bright 200W ultra high power lamp. The projector includes a Progressive Scan function, and is compatible with HDTV and DVD component inputs. A digital keystone feature corrects image distortion caused by projector angle, providing an even, square projection frame. The exterior is made of a lightweight magnesium alloy. The projector also features a digitized pointer device, equipped with a mouse-click function that allows educators to conduct presentations while standing away from the computer. It also allows educators to annotate images as they are projected.

Also from Canon, the DZ-3600U is a digital imaging system delivering a resolution of 1,900 x 1,424 pixels. Users can enhance presentations and videoconferencing by capturing an entire 8 1/2 x 11 document at once, legible to 8 pt. type. These images can then be displayed on a computer, presented with a projector, published online, or transmitted with a videoconferencing system. High-speed image capture allows users to quickly and conveniently integrate critical material into any presentation. The digital images can easily be displayed directly through a front projector. Even images as small as postage stamps can be seen in the back row, without the presenter needing to constantly zoom in. Canon, Lake Success, NY, (516) 328-5960,

One of Sony's additions to its line of SuperLite LCD projectors is the VPL-CS10, an affordable unit with a 0.9" LCD panel and offering 1000 ANSI lumen brightness. The compact unit weighs 7.7 lbs. and delivers SVGA (800 x 600) resolution. The projector is equipped with a USB hub port that makes it possible to launch files from an attached computer via remote control, or to allow an attached computer to control the projector. The unit includes Projector Station 2.0 software, so it can be daisy-chained with up to 127 other projectors. The VPL-CS10 also offers multiple capability with an internal scan converter, allowing it to display images from VGA to SXGA. Its horizontal frequency is 15 to 91 kHz, and it also includes composite video, Y/C video, component video and 15K RGB video signals. Sony, San Jose, CA, (800) 686-SONY,

Sharp Electronics Corp.'s latest LCD product is the XG-V10WU, intended for large conference rooms, lecture halls and custom professional installations. This Conference Series projector offers 4,700 ANSI lumens, along with a wide range of features designed specifically for professional markets and installations. The projector has SXGA resolution and advanced video processing to improve picture quality. It comes with a unique software application package that enables users to monitor and control the device remotely, and offers network and video wall capability. The software also lets the XG-V10WU self-diagnose any system errors that may occur, and send an error message to the control PC. The control PC can be programmed to send error messages via e-mail to a predetermined list, informing the appropriate parties that maintenance is required. The software also allows the projector to be daisy-chained to up to 250 other projectors, all of which can be controlled from a single PC.

For smaller projection needs, Sharp's NotevisionP10 LCD projector is designed to perform both in stationary conference room applications and for portable use.
