Abstract

본 발명은 안테나로부터의 텔레비전방송 수신신호의 신호세기를 검출하고 그 신호세기를 기초로 안테나로부터의 텔레비전방송 수신신호를 적절히 조절하여 튜너에 인가함으로써, 차량의 이동으로 인해 수시로 변동되는 텔레비전 수신감도를 일정하게 유지시켜서 보다 안정된 화면을 디스플레이 할 수 있도록 된 차량탑재용 텔레비전의 수신감도 보정장치를 제공하기 위한 것이다. 이를 위해 본 발명은, 키입력부(12)로부터의 선국키입력신호에 따라 튜너(18)가 해당 채널을 선국하도록 제어함과 더불어 상기 키입력부(12)로부터의 제어키입력신호에 따라 장치의 해당 제어동작을 실행하는 마이컴(10)을 구비한 차량탑재용 텔레비전에 있어서; 안테나와 튜너(18) 사이에 설치되어 상기 안테나에서 수신된 텔레비전방송 수신신호의 신호세기를 조절하기 위한 신호세기조절부(14)와, 상기 신호세기조절부(14)로부터 상기 튜너(18)로 인가되는 텔레비전방송 수신신호의 신호세기를 검출하기 위한 신호세기검출부(16)를 더 설치하고; 상기 마이컴(10)은 상기 신호세기검출부(16)로부터의 신호세기를 입력받아 이 신호세기를 기초로 상기 신호세기조절부(14)에 신호세기조절용 제어신호를 인가하도록 되어 있는 것을 특징으로 한다.The present invention detects the signal strength of a television broadcast signal from an antenna and adjusts the television broadcast signal from the antenna accordingly based on the signal strength to apply to the tuner so that the television sensitivity is frequently changed due to movement of the vehicle. It is to provide a reception sensitivity correction device for a vehicle-mounted television that can be kept constant to display a more stable screen. To this end, the present invention controls the tuner 18 to tune the corresponding channel according to the tuning key input signal from the key input unit 12, and the corresponding device of the device according to the control key input signal from the key input unit 12. A vehicle-mounted television having a microcomputer 10 for executing a control operation; A signal strength adjusting unit 14 installed between the antenna and the tuner 18 to adjust the signal strength of the television broadcast reception signal received from the antenna, and from the signal strength adjusting unit 14 to the tuner 18. Further providing a signal strength detecting section (16) for detecting the signal strength of the applied television broadcast signal; The microcomputer 10 receives the signal strength from the signal strength detecting unit 16 and applies a signal strength adjusting control signal to the signal strength adjusting unit 14 based on the signal strength.
