Method and device for controlling close-range TV view

Abstract

The invention relates to a method for controlling close-range TV view, which comprises the steps of: monitoring the relative position information of a viewer; judging whether the view distance is smaller than a preset distance according to the relative position information, if so, generating a timing signal; beginning to time according to the timing signal, checking whether the timing signal exists after counting for a preset period, if so, generating a counting signal and beginning the next timing procedure; counting the timing period according to the counting signal; beginning to alarm if the timing period reaches to a preset period number within a preset statistic duration; if not, zero clearing the statistic time. The method of the invention has the advantages of performing continuous monitor and statistic for multiple timing periods with one timing period as a unit and judging the close-range view by the timing period statistic within the preset statistic duration, thereby guaranteeing a more accurate judging result, reducing the wrong judgment rate and guaranteeing the working stability of the TV. The invention also relates to a device for controlling close-range TV view.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a method and device for controlling close-up viewing of televisions. Background technique [0002] When the user watches TV, there is an optimal viewing distance, which is generally 2.5-3.5 times the diagonal of the TV display screen. If the distance between the user and the TV is too close, it will affect the eyesight, especially for young people who have been in close proximity for a long time. Watching TV at a distance can easily lead to myopia. [0003] In recent years, there have been various methods and devices for preventing watching TV at a close distance, most of which are related prompts or alarms after the user stays within a fixed distance for a fixed time. For example, if a user watches continuously for 5 minutes within a range of 2.5 meters, a prompt or alarm will be issued. [0004] Existing technologies simply make judgments based on the accumulation of user...

Problems solved by technology

In this way, it is easy to artificially make the judgment system make a misjudgment, making it lose the role of controlling close-up viewing

For another example, if the user passed the close range in the first second and the last second of 5 minutes, but did not watch TV in the rest of the time, it is impossible to make a correct judgment at this time
