Display equipment and display method

Abstract

The invention provides display equipment and a display method. The display equipment comprises an image obtaining unit, an extracting unit, a calculating unit and a comparing and reminding unit. The image obtaining unit is used for obtaining image data of a viewer; the extracting unit is used for extracting human face feature parameters from the image data; the calculating unit is used for calculating feature value according to the image data and the human face feature parameters; the comparing and reminding unit is used for comparing the feature value with a preset feature value, and reminding the viewer of whether the viewing distance is safe or not according to a comparison result. On the basis of the image sensing technology, only the viewing distance of a specific user can be detected, interference of other users and objects is ignored, the viewer is reminded of whether the viewing distance is safe or not in real time, the possibility that the viewer watches a television at a short distance is reduced, false operation of short-distance reminding is reduced, and short-distance reminding accuracy and viewing comfort are improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a display device and a display method thereof. Background technique [0002] With the advancement of technology, the content of display devices is becoming more and more abundant, and the functions are becoming more and more diversified. At the same time, the screen size of display devices is also increasing, and the time for users to watch display devices increases accordingly. Watching for a long time will have a certain impact on people's vision, especially when viewing display equipment at close range, it will not only damage the eyes, but also affect people's physical and mental health due to the radiation and electromagnetic radiation generated. Especially for children, watching display devices at close range for a long time will cause greater harm. [0003] In the prior art, when the viewer is watching too close to the display device, it can automatically dete...

AI Technical Summary

Problems solved by technology

The infrared ranging method can realize the ranging function, but the disadvantage is that it is easy to misuse, the accuracy is different, the external influence is greater, and the viewer cannot be distinguished, which is blind

For example, when multiple users watch TV at the same time, the specific viewer is outside the safe distance, if other users or objects suddenly appear within the detection range or within the safe distance, the TV will judge that the viewer is too close, affecting the actual viewing effect

In addition, the transmitter and receiver are placed outside, which not only affects the appearance, but also affects the placement of the equipment, which disturbs the viewers and brings inconvenience
