Abstract

본 발명은 시청거리를 측정하여 최적의 거리에서 언제나 선명한 화면을 감사할 수 있도록 하는 시청거리 조절이 가능한 티브이 수상기에 관한 것으로 특히 거리 또는 광량감지센서를 수상기 하우징 전면에 장착하고 상기 센서 출력을 마이컴(MICOM)에서 비교분석하여 그 비교치에 의해 영상신호부와 음성신호부를 선택적으로 제어하여 줌으로써 시청자가 티브이 수상기 앞으로 접근하는 경우 화면의 밝기를 어둡게 하거나 소리를 줄여 어린이의 근접 시청에 따라 시력장애를 효과적으로 보호할 수 있도록 한 시력보호장치와 그 방법을 개시하는 것이다.The present invention relates to a TV receiver capable of adjusting the viewing distance so that a clear screen can be always audited at an optimum distance by measuring the viewing distance. In particular, the distance or light amount sensor is mounted on the front of the housing housing and the microcomputer (sensor output) MICOM) analyzes and analyzes the video signal part and the audio signal part selectively based on the comparison value, so that when the viewer approaches the TV set, the screen brightness is darkened or the sound is reduced to reduce the visual impairment according to the proximity of the child. Disclosed are a vision protecting device and a method for protecting the same.

이같은 본 발명은 거리 또는 광량을 감지하여 화면을 어둡게 하거나 소리가 않나도록 함으로써 올바른 시청자세와 습관을 길러주는데에도 매우 바람직하게 이용될 수 있는 것이다.The present invention can be very preferably used to develop a correct viewing posture and habits by darkening the screen or making no sound by sensing distance or amount of light.

Claims

The distance sensor 21 is installed on the front surface of the housing in which the water pipe 10 is housed on the TV receiver. The output of the sensor 21 is determined by comparing with the setting data in the microcomputer 20, and the microcomputer 20 includes the button part. The microcomputer 20 may be selectively set or reset by the sensor operation button 2 'of (2), and the microcomputer 20 compares the distance measured through the sensor with the distance setting data to supply the power source 11 or the image signal unit 4 TV receiver equipped with a viewing distance adjusting device, characterized in that the normal mode is performed only within the set distance by allowing the selective control.

The TV receiver having a viewing distance adjusting device according to claim 1, wherein the distance detecting sensor (21) comprises a distance detecting light emitting lamp (21-1) and a light receiving lamp (21-2).

In the TV receiver, a light quantity detecting sensor 21 'is installed at an arbitrary front surface of the housing in which the receiving tube is accommodated. The microcomputer 20 selects the video signal unit 4 or the audio signal unit 9 by comparing the amount of light detected through the sensor with the light amount setting data. TV receiver equipped with a viewing distance adjusting device, characterized in that the normal mode can be performed only in the set light amount by configuring to control.

A method of controlling a TV receiver, the method comprising: checking whether a detection signal is input and sequentially checking whether a distance signal and a brightness control signal are input, and controlling brightness of an image signal unit; Turning off the power supply unit in an abnormal state when no luminance control signal is input; Sequentially checking whether a light quantity signal and a luminance control signal are input when the distance signal is not input, and controlling the image signal unit; And controlling the audio signal unit in an abnormal state when no luminance control signal is input.
