Abstract
본 발명은 마이콤의 제어에 의해 IC카드를 이용하여 콘트라스트를 조절할 수 있도록 된 텔레비전 수상기의 콘트라스트 조절방법에 관한 것으로, 콘트라스트를 조절하면 현재의 콘트라스트 레벨을 IC카드에 저장하는 단계(100, 101); 사용자의 키입력에 따라 콘트라스트를 새로운 레벨로 설정하는 단계(102); 소정의 기준시간이 경과되면 사용자가 설정한 콘트라스트레벨들의 빈도수를 비교하여 빈도가 가장 높은 콘트라스트레벨을 IC카드에 저장하는 단계(103, 104); 및 전원이 온되면 상기 IC카드에 저장된 콘트라스트레벨로 콘트라스트를 설정하는 단계(105, 106);로 구성되어 IC카드에 콘트라스트레벨을 기록하므로 사용자가 소지한 IC카드에 따라 사용자별로 최적의 콘트라스트를 제공할 수 있고, 정전등으로 전원이 완전히 꺼진 경우에도 설정된 데이타가 손실되지 않는 잇점이 있다.The present invention relates to a contrast adjustment method of a television receiver that is capable of adjusting contrast using an IC card under the control of a microcomputer. Setting contrast to a new level in accordance with a user's key input (102); Comparing the frequency of the contrast levels set by the user when the predetermined reference time has elapsed and storing the highest contrast level in the IC card (103, 104); And setting the contrast to the contrast level stored in the IC card when the power is turned on (105, 106), and recording the contrast level on the IC card, thereby providing optimum contrast for each user according to the IC card possessed by the user. The advantage is that the set data is not lost even if the power is completely turned off due to the power failure lamp.
