Abstract

본 발명은 OSD(ONSCREEN DISPLAY)기능이 구비된 텔레비젼수상기에 관한 것으로서, 특히 리모콘장치로 부터 수신되는 적외선신호의 세기에 의해서 시청자와 텔레비젼수상기사이의 거리를 인식하여 그 시청거리에 비례하여 OSD의 온시간의 장단을 조절함으로써 시청자가 화면상에 나타나는 OSD의 문자 또는 도형을 보다 용이하게 인지할 수 있도록 한 텔레비젼수상기의 시청거리에 따른 OSD온시간조절장치 및 그 방법에 관한 것이다.The present invention relates to a television receiver having an OSD (ONSCREEN DISPLAY) function, and more particularly, to recognize the distance between the viewer and the television receiver by the intensity of the infrared signal received from the remote control device, and to turn on the OSD in proportion to the viewing distance. The present invention relates to an OSD on-time control device and a method according to a viewing distance of a television receiver, which enables a viewer to more easily recognize characters or graphics of an OSD displayed on a screen by adjusting the length and length of time.

본 발명은 감지센서(9)에서 수신한 리모콘장치(8)의 적외선신호의 세기를 근거로 텔레비젼수상기와 시청자와의 거리를 판별하는 시청거리인식부(30), 그리고 마이크로프로세서(11)의 제어에 따라 상기 시청거리인식부(30)에서 인식한 시청거리에 따른 OSD 온시간을 계수하는 타이머(31)을 구비하며 ; 적외선의 리모콘신호가 입력된 경우에 시청거리인식부(30)에 입력된 경우에 시청거리인식부(30)는 적외선의 리모콘신호의 세기를 근거로 시청거리를 판별하고 그 시청거리에 대응하는 신호를 마이크로프로세서(11)에 인가하고, 마이크로프로세서(11)에 시청거리 인식부(30)로 부터 시청거리에 대응하는 신호가 인가된 경우에 OSD발생부(12)를 제어하여 OSD를 온함과 동시에 타이머(31)를 제어하여 시청거리에 따른 OSD온시간을 계수토록 하고, 타이머(31)로 부터의 신호에 따라 OSD 온시간이 경과되었는지를 판단하여, OSD 온시간이 경과되었을 경우 OSD 발생부(12)를 제어하여 OSD를 오프시키는 것을 특징으로 한다.The present invention controls the viewing distance recognition unit 30 and the microprocessor 11 for determining the distance between the television receiver and the viewer based on the intensity of the infrared signal of the remote control device 8 received by the sensor 9. A timer 31 for counting an OSD on time according to the viewing distance recognized by the viewing distance recognition unit 30 according to the present invention; When an infrared remote control signal is input to the viewing distance recognition unit 30, the viewing distance recognition unit 30 determines the viewing distance based on the strength of the infrared remote control signal and the signal corresponding to the viewing distance. Is applied to the microprocessor 11, and when the signal corresponding to the viewing distance is applied from the viewing distance recognition unit 30 to the microprocessor 11, the OSD generating unit 12 is controlled to turn on the OSD. The timer 31 is controlled to count the OSD on time according to the viewing distance, and it is determined whether the OSD on time has elapsed according to a signal from the timer 31, and when the OSD on time has elapsed, an OSD generator ( 12) to control the OSD off.
