Features
· Three handy features in a single body. The projector for the multimedia age 1. Documents, catalogs and other printed matter can be projected directly from the scanner. This frees the user from the need to make OHP film inserts for each document. 2. Personal computer screens can be projected. This allows the user to make detailed presentations using information on a personal computer. 3. Videos and DVD images can be projected as they are. This aids the user in making visually appealing presentations. Easy-to-understand and simple operation Projection of printed matter, personal computer screens and video images can be selected at the push of a button. High cost effective resource-saving design OHP film inserts no longer need to be made, which saves wasted time and expense.

Expressive color images The projector is equipped with a high-resolution 2 million pixel single-array color CCD camera. This allows subtle midtones in color documents to be reproduced faithfully and sharp as projected images in full color (16,770,000 colors). Enlarged display without changing the size of the projected image When projecting documents such as catalogs and word-processor documents containing small text that have not been made specially for presentations, the document can be enlarged without changing the size of the projected image for easier viewing. Provided with display functions for compressed or enlarged PC screen Screens of resolution more than 1024 x 768 dots are displayed compressed to 1024 x 768 dots without any loss in character quality. Lower resolutions such as 640 x 480 can also be enlarged to 1024 x 768 dots.
