Embodiment Construction

[0014] Step 1: The user enters the distance s between the current face and the screen in the system 0 , the system will calculate the ratio m=l / s according to the side length l of the face recognition frame detected by the video capture device 0 .

[0015] Step 2: The video capture device detects whether the user is working in front of the video display terminal through the video capture device combined with the face detection algorithm every t seconds, and saves the side length l of the face detection frame and time information.

[0016] Step 3: Scan the side length l of the face detection frame recorded in the user record, and use l / m to calculate the distance s between the user's eyes and the video display terminal device at this time. If s is less than the set threshold S, assign the time of the current record to t 3 ;Sequentially calculate the s value of the next record, if the s value is less than the set threshold S, assign the time of this record to t 4 , and calcul...

Abstract

The invention relates to an eye protection method for users in front of a video display terminal. The method includes: using a video acquisition device to motor, in real time, states of a user in front the video display terminal, including whether the user is in front of the video display terminal, and calculating a continuous operation time t0 and a distance s from user's eyes to the video display terminal for the user in front of the video display terminal according to the states; when the continuous operation time t0 of the user in front of the video display terminal is larger than a certain threshold T0, blurring the video display terminal and displaying an icon for overlong work time so as to remind the user of taking a rest; and when time t1 at which the distances from the user's eyes to the video display terminal is smaller than a certain threshold S is larger than a certain threshold T1, blurring the video display terminal by Gaussian Blur and displaying an icon for the too short distance between the user and the video display terminal so as to remind the user of keeping the proper distance from the video display terminal. The video display terminal which is burred has no effect on practical operation of users.

Description

technical field [0001] The invention relates to an eye protection method in front of a video display terminal, in particular to an eye health care method for people who work in front of a video display terminal for a long time. Background technique [0002] With the development of science and technology, more and more electronic devices appear in people's lives, and people can use these electronic devices for daily study, work and entertainment anytime and anywhere. These electronic devices facilitate people's daily life, but if they are used in an improper way such as: long time, short distance, etc., it will also greatly increase the burden on people's eyes, causing eye fatigue, vision loss and many other eye problems. The problem will cause irreversible damage to people's eyes in the long run. To reduce or avoid this kind of damage, the operation in front of the video display terminal of the user should reasonably control the use time and keep an appropriate distance fro...
