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, www.canonprojectors.com.
