Technology to Enlarge Text & Images
By Andrew Leibs
Handheld Video Magnifiers
Handheld video magnifiers look like square magnifying glasses. They have built-in cameras for capturing and enlarging images and controls for zooming in and out and adjusting brightness, contrast, and text and background colors. Nearly all have a “freeze frame” feature; newer models enable users to store multiple image files they can download to a computer.
Desktop Video Magnifiers
Desktop video magnifiers, once known as CCTVs, provide higher magnification and image quality than handhelds. A larger viewing screen also makes it a better choice for sustained reading. Many models also offer OCR scanning and text to speech to read magnified text aloud. The main drawbacks are price (most start around $2,400) and lack of portability.
