Abstract

본 발명은 디지탈 입출력이 가능한 칼라비디오 프린터장치에 관한 것으로, 종래의 칼라비디오 프린터장치는 아날로그 비디오신호를 입력받아 프린트하므로 아날로그/디지탈, 디 지탈/아날로그 변환시 신호잡음비가 감소되므로 고화질의 사진을 출력시킬 수 없는 문제점이 있었다.The present invention relates to a color video printer device capable of digital input / output, and the conventional color video printer device receives an analog video signal and prints the signal noise ratio during analog / digital and digital / analog conversion, thereby outputting a high quality picture. There was a problem that could not be.

따라서 종래의 문제점을 해결하기 위하여 본 발명은 외부로부터 입력되는 디지탈신호를 그대로 프린트할 수 있도록 하거나 비디오입력부를 통해 입력되는 아날로그신호를 프린트할 수 있도록 함과 아울러 디지탈로 출력되는 기기등과 병행하여 사용할 수 있도록 함으로써 생활의 편리함을 도모하고 높은 신호/잡음비와 고화질의 출력을 얻도록 한 효과가 있다.Therefore, in order to solve the conventional problems, the present invention can be used to print digital signals input from the outside as it is, or to print analog signals input through a video input unit and to be used in parallel with a digital output device. By doing so, it has the effect of making life easier and obtaining high signal / noise ratio and high quality output.
