The TVi Colour is a closed circuit television (CCTV) video magnifier designed for use by individuals with low vision. It can be used to magnify text or photos. It consists of a control box and a small TV camera in an ergonomic, handheld "mouse." The camera incorporates a zoom lens which allows the level of magnification to be altered without refocussing. The magnified image is displayed on a standard television in high contrast black-on-white or white-on-black for text, or in full-color photo mode for photographs. The mouse has rollers which facilitate easy scanning of text, allowing difficult-to-read items such as medicine bottles or cooking instructions on food containers to be magnified easily. An exposure control helps to enhance poor quality text. An overview mode can be used for orientation or for tasks such as looking at one's own face. All functions can be controlled from the mouse. OPTIONS: A handwriting stand is available. DIMENSIONS: Control box is 1.4 x 4.1 x 3.1 inches; camera unit is 2.2 x 4.3 x 2 inches. WEIGHT: Total device (control unit plus damera unit), 1 pound 3 ounces; camera unit alone, 4 ounces.
