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

제2도는 본발명의 블럭구성도2 is a block diagram of the present invention

제3도의 (a)(b)는 본발명의 영상확대관계를 나타낸 것으로 (a)로 확대전의 화면을 나타낸 정면도, (b)는 확대시의 화면정면도(A) and (b) of FIG. 3 show the image magnification relation of the present invention, (a) is a front view showing the screen before magnification, and (b) is a front view at the time of magnification.

Claims (1)

리모콘(1)으로 프리앰프(2)를 통해 마이크로프로세서(3)를 구동하여 동기출력회로(4)를 제어함에 따라 수상관(CRT)의 화면에 영상을 재생토록 구성한 텔레비젼에 있어서, 상기 텔레비젼의 화면의 좌상 4분면의 영상을 확대시키기위해 상기 동기출력회로(4), 복수의 수평 및 수직주파수(h1)(h2)(v1)(v2)가 각각 수평 및 수직드라이브회로(5)(10)을 통과하고 이와 동시에 각기 수평 및 수직카운터(5)(11), 수평 및 수직 출력선택회로(7)(12)를 통해 절환스위치(SW1)(SW2)를 제어하여 수평 및 수직출력회로(8)(9),(13)(14)를 선택하여서 수평 및 수직 평향 코일(HDY)(VDY)에 인가시켜서 된것을 특징으로하는 편향주파수변화에 의한 확대기능 텔레비젼.In a television configured to reproduce an image on a screen of a water pipe (CRT) by controlling the synchronous output circuit 4 by driving the microprocessor 3 through the preamplifier 2 with the remote controller 1. In order to enlarge the image of the upper left quadrant of the screen, the synchronous output circuit 4 and the plurality of horizontal and vertical frequencies h 1 (h 2 ) (v 1 ) (v 2 ) are horizontal and vertical drive circuits 5, respectively. (10) and at the same time control the switching switch (SW 1 ) (SW 2 ) through the horizontal and vertical counters (5) (11), horizontal and vertical output selection circuits (7) (12), respectively. An enlarged function television with a deflection frequency change, characterized in that the vertical output circuits (8) (9) and (13) (14) are selected and applied to horizontal and vertical deflection coils (HDY) (VDY). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
