AI Technical Summary

Problems solved by technology

[0005] 1. If the user only watches at close range for a short period of time, then the above technical solution will cut off the TV signal or turn off the TV against the user's will; if the user often walks around in front of the TV, then the above technical solution will cause The repeated turning on and off of the TV screen affects the normal viewing of the user, which is not humane enough
Frequent switching on and off of the TV will also affect the life of the TV
[0006] 2. Single function, once installed, it is difficult for users to change
For example, the response time of the system, the voice warning function and the switch of the vision protection function are determined by the hardware parameters, which are difficult for users to set and are not humanized enough.
[0007] 3. The hardware structure is complex and the implementation cost is high

Embodiment Construction

[0024] Combine now figure 1 , a flow chart of a method for restricting watching television at close range in the present invention, illustrating the action process of the present invention. Step 101 is an initial action, and the infrared human body detection module starts to run. In step 102, the infrared human body detection module monitors whether there is anyone in the detection area in front of the TV, if there is no one, the monitoring state is maintained, and if someone enters, the next step 103 is performed. In step 103, timing is started and the brightness value of the existing TV picture is saved. In step 104, it is judged whether the timing ends, if no, then proceed to step 106, continue to monitor whether the people in the detection area in front of the TV set leave; if yes, it means that the timing ends, then proceed to step 105, reduce the brightness of the television screen , and re-timing, enter the next step 106. In step 106, the infrared human body detectio...

Abstract

The method thereof comprises: an infrared human body detection module is used to detect the area in front of a TV set in order to decide if there is a person in the area; if there is a person detected in the area, the detection module starts a time keeping; if before the ending of the time keeping the person has not yet left the area, the brightness of TV set is gradually reduced and until to a lowest brightness value; when the detection module detects the person has left the area, it recovers the brightness of TV screen. The apparatus thereof comprises an infrared human body detection module, a CPU, a memory, a backlight source of display screen. The detection signal of infrared human body detection module controls the brightness of display screen through the CPU.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a method for restricting watching television at a close distance and a television device implementing the method. Background technique [0002] Along with the development of science and technology, multimedia technologies such as TV have been widely used in millions of households. Today, with more and more TV programs, TV sets have become an indispensable household appliance for ordinary people. Television can not only help users spend their leisure time, but also bring them rich knowledge at the same time. Due to the lack of self-awareness to protect eyesight, many children have developed the bad habit of watching TV at close range. Childhood is a critical period for visual development. Watching TV at close range for a long time can easily cause myopia, which will have an irreparable impact on lifelong visual health. [0003] The adverse effect of watching TV at close ran...
