Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] refer to figure 1 and figure 2 , figure 1 It is a schematic flow chart of the first embodiment of the reminding method for watching TV at close range in the present invention; figure 2 It is a schematic diagram of the ranging principle of the camera in the reminder method for watching TV at a close distance according to the present invention.

[0047] Reminders for watching TV at close range include:

[0048] Step S10, receiving the viewing image sent by the camera, the viewing image is obtained by shooting the front of the display screen;

[0049] Step S20, according to the face image in the viewing image, calculate the measured interpupillary distance of the viewer's eyes;

[0050] Step S30, comparing the measured IPD with the preset image IPD, and reminding the user according to the comparison result....

Abstract

The invention discloses a method for warning on watching TV in a near distance. The method includes receiving an image about watching sent by a camera; calculating measuring pupil distance of eyes of a watcher according to a face image in the image about watching; and comparing the measuring pupil distance and preset image pupil distance, and warning the watcher according to the compared results. The invention further discloses a device for warning on watching TV in near distance. The current watching distance of watching TV by the watcher can be detected in real time by a TV, the watcher is warned to keep reasonable watching distance when the watching distance is too close, and accordingly possibility of watching TV in the near distance by the watcher (in particular to a child) can be decreased, incorrect actions of watching distance detection can be reduced, and accuracy of detection can be improved.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a reminding method and device for watching TV at close range. Background technique [0002] With the improvement of living standards, in order to meet the higher and higher consumption needs of consumers, the screen size of TV sets is also getting larger and larger, and large-screen TVs have entered thousands of households. And as people become more and more dependent on TV, they spend more and more time watching TV. However, watching TV for a long time will have a certain impact on people's vision, especially when watching TV too close to the TV, the damage to the eyes will be even greater. Therefore, existing televisions can automatically detect and remind the viewer to keep an appropriate viewing distance when the user is too close to the television to watch the television. At present, the commonly used method is to use infrared rays to detect, that is, to sense the us...
