Abstract

By handling the key of the key input part(10) of a TV, while watching the TV, TV's movement environment is set up. A microcomputer(20) recognizes and transfers TV's movement environment to the new movement environment changed by the key input. The microcomputer(20) works an OSD letter processing part(30) and outputs OSD letters corresponding to the established TV movement environment from a synthesis part(40). As the synthesis part synthesizes a video signal provided from a video processing part(600) and OSD letters provided from the OSD letter processing part and outputs with the picture, the audience can view the broadcasting signal and the change of the TV movement environment.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing eye fatigue when watching a television receiver for relieving eye fatigue caused by watching television broadcast for a long time in a television receiver capable of processing OSD text and displaying on a screen. Preferably, the present invention relates to a method for preventing eye fatigue when watching a television receiver, which enables eye gymnastics such as up, down, left, right, or circular movements at regular intervals without focusing on the eyes of viewers watching a television receiver.

In general, when watching a television receiver for a long time, the viewer constantly looks only at a certain portion of the television receiver, and there is a drawback of eye fatigue because there is no movement of the pupil. Therefore, when watching a TV receiver for a long time there was a problem that the vision is reduced.

The present invention has been made to improve the above-mentioned problems, and the attention of the viewers to move in a vertical direction or up and down or right or right every time without focusing the eyes of the viewer watching the television receiver It is an object of the present invention to provide a method of preventing eye fatigue when watching a television receiver, which generates an off OSD character to protect the eyesight of the viewer.

According to the present invention for realizing the above object, in the television receiver performing the function of displaying the OSD text on the screen, when the operation mode of the television receiver is set to the eye movement mode, the graphic OSD text is vertical on the screen. , To be moved horizontally, diagonally or in a circular direction.

Hereinafter, the configuration of the present invention in more detail with reference to the accompanying drawings as follows.

The television receiver for implementing the present invention is schematically shown in FIG. 1 as shown in FIG. 1, the key input unit 10, the microcomputer 20, the OSD text processing unit 30, the synthesizing unit 40, the screen 50, the video signal. It consists of the processing part 60.

Here, 10 denotes a key input unit including keys for setting an eye movement mode and various operating environments of the television receiver, and 20 denotes a key operation state of the key input unit 10 or an operation state of the television receiver. The microcomputer controls the overall operation of the television receiver, including the eye movement, and 30 controls the OSD characters and other OSD characters for eye movement by the control of the microcomputer 20 that recognizes the input of the key input unit 10. OSD text processing part to output.

In addition, 40 denotes a synthesizer for synthesizing the OSD character processed by the OSD character processor 30 and the video signal processed by the video signal processor 60 below, and 50 denotes an OSD character synthesized by the synthesizer 40. 60 is a video signal processor that processes a video signal among RF signals through a tuner (not shown).

Exemplary Drawing 2 is another flowchart of the present invention, and Exemplary Drawings 3 to 5 are exemplary views showing one embodiment of graphic OSD characters displayed on a screen of a television receiver according to the present invention.

Referring to the effects of the present invention configured as described above are as follows.

According to the present invention, after the RF broadcast signal transmitted from a broadcasting station is processed by an RF / IF signal receiving and processing unit through an antenna (not shown), the video signal is processed by the video signal processing unit 60 and output to the screen 50. The audio signal processor, which is not shown, is applied as an audio signal, processed, and then output to the speaker.

If the operating environment of the television receiver is set by operating a key of the key input unit 10 while receiving and watching a broadcast signal, the microcomputer 20 recognizes this and controls the operating environment of the television receiver to be converted into a key input. do. In addition, the microcomputer 20 operates the OSD text processor 30 to output the OSD text corresponding to the operating environment of the television set to the synthesizer 40. Therefore, the synthesizer 40 synthesizes the video signal supplied from the video signal processor 60 and the OSD character supplied from the OSD text processor 30 and outputs it to the screen 50. And audio signal), and the operation environment of the television receiver can be known.

In this case, when the operation mode of the television receiver is set to the eye movement operation mode and the television receiver is watched, the OSD character of the figure-shaped OSD characters necessary for the eye movement according to the eye movement environment set in the microcomputer 20 of the television receiver is displayed. The video signal processed by the video signal processor 60 and the synthesizer 40 are combined to output the screen 50. Thus, the viewer can reduce eye strain caused by watching a television receiver for a long time.

Referring to the operation of the microcomputer 20 for controlling such an operation in detail with reference to FIG. 2, the operation mode of the television receiver is an eye movement operation mode in the microcomputer 20 of the television receiver which normally receives and outputs a broadcast signal. Will be judged. When the operation mode of the television receiver is the eye movement mode, the eye movement environment made by the operation of the key input unit 10 is stored in the microcomputer 20, and the eye movement operation time according to the set environment is waited for. .

That is, when the set eye movement operation mode starts, the OSD characters in the shape of figures are moved to the diagonal shape of the screen as shown in FIG. 3 (a) (b) (c) of FIG. 3 or (a) (b) of FIG. As shown in (c), the screen is moved up, down, left, and right, or the periphery of the screen is rotated as shown in (a) (b) (c) of FIG. The set eye movement operation is repeatedly performed at a predetermined time interval. When the eye movement operation mode or the eye movement operation mode ends, the set eye movement operation receives a broadcast signal and normally outputs the broadcast signal to the screen.

Preferably, the combination of the OSD characters in the figure shape of FIGS. 3 to 5 may be combined to set an eye movement operating environment, which may bring about more effective eye movement effects. In particular, as shown in FIGS. 3 to 5 on the screen, the moving OSD character can be increased by changing the rotation direction in the clockwise or counterclockwise direction to increase the eye movement effect. In addition, by combining the shape of the OSD character moving on the screen to form a polygon that stands out to the viewer as well as the circular shape, the eye movement effect can be further increased.

As described above, the present invention sets an eye movement operating environment required for eye movement while watching a television receiver, and outputs the eye movement environment on the screen at a set time interval, so that the eyes coming from watching the television receiver for a long time are displayed. It has the effect of reducing fatigue.
