Method and device for protecting eyes through screen displaying setting
First Claim
1. A method for protecting eyes through screen displaying setting, wherein every time period, a CCD or CMOS camera captures images of a VDT user and the working environment of the VDT user, then the illumination of the environment of the VDT user, the fatigue of the VDT user, and the distance between the VDT user and a display are determined;
- the brightness, contrast, colors and clearness of the font of the terminal display are adjusted and controlled automatically according to the illumination of the environment of the VDT user and the fatigue of the VDT user;
when the illumination of the environment of the VDT user, the fatigue of the VDT user, and the distance between the VDT user and a display has been over a predetermined condition, an alarm will emit to inform the user.

Abstract
A system formed by a device on the CCD or CMOS above a terminal display and a display screen setting program is disclosed. This system will set the working environment of a VDT user to an optimum value. The images of the VDT user and the peripheral environment are captured. Then the working environment of the VDT user, the illumination of the environment of the VDT user, the fatigue of the VDT user, and the distance between the VDT user and a display are determined. The brightness, contrast, colors and clearness of the font of the terminal display are adjusted and controlled automatically according to the illumination of the environment of the VDT user and the fatigue of the VDT user. When the illumination of the environment of the VDT user, the fatigue of the VDT user, and the distance between the VDT user and a display has been over a predetermined condition, an alarm will emit to inform the user. The fatigue and tightness of eyes of a VDT user is reduced effectively so that the eyes of user are well protected.
