Abstract

본 발명은 텔레비젼 수상기의 부분화면 확대장치와 확대방법에 관한 것으로서, 특히 화면비를 4:3이나 16:9의 비로 변환시키고, 화면비가 변화된 상태에서 임의의 영상을 확대할 수 있는 부분화면 확대장치와 확대방법에 관한 것이다.The present invention relates to a partial screen magnification apparatus and a magnification method of a television receiver, and in particular, a partial screen magnification apparatus capable of converting an aspect ratio to a ratio of 4: 3 or 16: 9 and enlarging an arbitrary image in a state where the aspect ratio is changed; It relates to the expansion method.

종래의 화면 확대장치는 확대영상이 제한되어 있으며, 확대하기 위한 위치 또는 제한되어 있기 때문에 원하는 부분을 확대할 수 없으며 확대화면의 위치를 파악할 수 없는 문제점이 있다.In the conventional screen magnification apparatus, the enlarged image is limited, and since the enlarged image is limited or cannot be enlarged, a desired portion cannot be enlarged and the position of the enlarged screen cannot be grasped.

따라서, 본 발명은 상기 문제점을 해결하기 위해 화면비를 4:3이나 16:9의 비로 변화시키고, 화면비가 변화된 상태에서 임의의 영상을 확대할 수 있는 부분화면 확대장치와 확대방법이다.Accordingly, the present invention provides a partial screen magnification apparatus and a magnification method capable of changing an aspect ratio to a ratio of 4: 3 or 16: 9 and enlarging an arbitrary image in a state where the aspect ratio is changed to solve the above problem.
