Abstract

본 발명은 주거인이 부득이한 이유로 인해 집을 비우게 되는 경우 방법모드를 설정함으로써 건물의 소정위치에 설치시킨 비디오카메라에서 촬영되는 임의의 침입자를 자동으로 기록하여 필요시 재생시켜 침입자의 침입여부를 확인할 수 있도록 된 침입자확인기능을 갖춘 텔레비전을 제공하기 위한 것이다.The present invention automatically records any intruder photographed by a video camera installed in a predetermined position of the building by setting the method mode when the house vacant the house for unavoidable reasons to play if necessary to check whether the intruder invaded To provide a television with the advanced intruder identification function.

이를 위해 본 발명은, 화면디스플레이가 가능한 CRT를 갖춘 텔레비전에서, 방범모드를 설정/해제시킬 수 있는 모드설정부(1)와, 침입자의 침입여부를 확인하기 위한 확인신호입력부(2), 피사체의 촬영이 가능한 촬영수단(3), 상기 촬영수단(3)에서 촬영되는 영상신호를 기초로 APL치의 변화량을 검출하는 APL변화검출부(4), 시간계시용 데이터를 제공하는 타이머(5), 상기 방범모드설정시 상기 APL변화검출부(4)로 부터의 검출신호를 기초로 침입자의 침입여부를 판단하여 침입자침입시 스위치(S1)를 온시킴과 동시에 화면기록동작이 이루어지도록 제어함과 더불어 상기 확인신호입력부(2)로 부터의 확인신호입력시 기록된 화면의 재생동작이 이루어지도록 제어하는 마이컴(6), 상기 스위치(S1)가 온됨에 따라 상기 촬영수단(3)으로 부터의 영상신호를 디지탈변한시키는 AD변환부(7), 상기 타이머(5)로 부터의 시간데이터와 상기 AD변환부(7)로 부터의 영상신호를 합성하여 엔코딩하는 엔코더(8), 상기 마이컴(6)의 제어하에 상기 엔코더(8)로 부터의 화면데이터를 저장하는 데이터저장부(9), 상기 확인신호입력시 상기 마이컴(6)의 제어하여 상기 데이터저장부(9)로 부터 출력되는 화면데이터를 디코딩하는 디코더(10) 및, 상기 디코더(10)로 부터의 화면데이터를 아날로그변환시켜 상기 CRT로 인가시키는 DA변환부(11)로 구성된 것이다.To this end, the present invention, in the television equipped with a CRT capable of the screen display, the mode setting unit (1) that can be turned on / off the security mode, and the confirmation signal input unit (2) for checking whether the intruder invaded, A shooting means (3) capable of shooting, an APL change detection unit (4) for detecting an amount of change in the APL value based on the video signal photographed by the shooting means (3), a timer (5) for providing timekeeping data, and the crime prevention When the mode is set, it determines whether an intruder intrudes based on the detection signal from the APL change detection unit 4, turns on the switch S1 at the time of intruder intrusion, and controls the screen recording operation to be performed. When the confirmation signal from the input unit 2 is input, the microcomputer 6 for controlling the playback operation of the recorded screen is performed, and the video signal from the photographing means 3 is digitally changed as the switch S1 is turned on. The key is under the control of the encoder 8 and the microcomputer 6 which synthesize and encode time data from the AD converter 7 and the timer 5 and the video signal from the AD converter 7. Data storage unit 9 for storing the screen data from the encoder (8), Decoder for decoding the screen data output from the data storage unit 9 by the control of the microcomputer (6) when the confirmation signal input (10) and a DA converter 11 for converting the screen data from the decoder 10 to the CRT.
