Abstract

본 발명은 OSD(ON SCREEN DISPLAY)기능이 구비된 텔레비젼수상기에 관한 것으로서, 특히 텔레비젼수상기 주변의 조도, 즉 빛의 밝기를 인식하여 그 조도에 비례하여 OSD의 온시간의 장단을 조절함으로써 시청자가 화면상에 나타나는 OSD의 문자 또는 도형을 보다 용이하게 인지할 수 있도록 한 텔레비젼수상기의 조도변화에 따른 OSD 온시간조절장치 및 그 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver equipped with an OSD (ON SCREEN DISPLAY) function. In particular, the present invention relates to a television receiver that recognizes the illumination around the television receiver, that is, the brightness of light, and adjusts the length of the on-time of the OSD in proportion to the illumination. The present invention relates to an OSD on-time adjusting device and a method for changing the illuminance of a television receiver so that characters or figures of the OSD appearing on the screen can be more easily recognized.

본 발명은 주변의 조도를 감지할 수 있는 광센서가 구성되어 있고 상기 감지한 조도를 몇 단계로 구분하여 인식할 수 있는 조도인식부(30), 그리고 마이크로프로세서(11)의 제어에 따라 상기 조도인식부(30)에서 인식한 조도에 따른 OSD 온시간을 계수하는 타이머(31)를 구비하여 ; 키입력부(9)로 부터 어떤 신호가 인가된 경우에 OSD발생부(12)를 제어하여 OSD를 온시키고 조도인식부(30)로 부터의 신호에 의해서 현재의 조도를 판별하여, 타이머(31)를 제어하여 현재의 조도에 대응하는 OSD온시간을 계수토록 하고, 타이머(31)로 부터의 신호에 따라 OSD온시간이 경과되었는지를 판단하여, OSD온시간이 경과되었을 경우 OSD발생부(12)를 제어하여 OSD를 오프시키는 것을 특징으로 한다.The present invention is composed of an optical sensor that can detect the ambient illumination and the illumination recognition unit 30 that can recognize the detected illumination by dividing the light into several steps, and the illumination under the control of the microprocessor 11 A timer 31 for counting the OSD on time according to the illuminance recognized by the recognition unit 30; When a signal is applied from the key input unit 9, the OSD generating unit 12 is controlled to turn on the OSD, and the current illuminance is determined by the signal from the illuminance recognition unit 30, and the timer 31 To control the OSD on time corresponding to the current illuminance, and determine whether the OSD on time has elapsed according to a signal from the timer 31, and if the OSD on time has elapsed, the OSD generator 12 Control off the OSD.

Description

OSD On Time Control Apparatus and Method According to Illuminance Change of TV Receiver

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명의 조도변화에 따른 OSD온(on) 시간조절장치를 구비한 텔레비젼수상기의 블럭도.2 is a block diagram of a television receiver having an OSD on time control device according to the change in illuminance of the present invention.

Claims

In a television receiver comprising a key input unit 9, a microprocessor 11, and an OSD generator 12, an optical sensor for sensing ambient illumination is configured and the detected illumination is divided into several stages. And recognizable data is preset and the illumination recognition unit 30 for applying a signal corresponding to each step to the microprocessor 11 under the control of the microprocessor 11, and the control of the microprocessor 11 And an on-time timer (31) for counting the OSD on-time according to the illuminance recognized by the illuminance recognition unit (30).

The method according to claim 1, wherein the illuminance recognized by the illuminance recognition unit 30 and the OSD on-time counted by the timer 31 are preset in three to five steps. OSD On Timer.

In a television receiver comprising a key input unit 9, a microprocessor 11, an OSD generator 12, an illuminance recognition unit 30, and a timer 31 for counting the OSD on-time, the key input unit 9 In the first step of determining whether a signal is input from the control unit, the OSD generator 12 is turned on when a signal is applied from the key input unit 9, and the OSD is turned on to the signal from the illuminance recognition unit 30. The second step of determining the current illuminance by controlling the timer 31, the third step of counting the OSD on time corresponding to the current illuminance, and the OSD on time according to the signal from the timer 31 And a fourth step of determining whether or not the OSD on time has elapsed, and controlling the OSD generating unit 12 to turn off the OSD. Way.
