Abstract

본 발명은 비디오 프린터장치 및 그 방법에 관한 것으로, 신호입력원으로부터 화상신호를 유입하여 라인 단위로 미리 설정된 계조값과 계조비교후 발열체로 구성된 열전사헤드에 통전인자표현을 행하는 프린터장치에 있어서, 열전사헤드의 온도를 검출하는 온도센서, 온도센서의 결과에 대응하여 발열기간을 제어하는 스트로브신호를 발생하여 열전사헤드에 공급하는 온도보상부를 포함하여 TPH의 온도 변화에 대응하여 발열기간을 가변시켜 계조별 색의 농도가 일정하게 표현함으로써 고화질의 화상을 프린트할 수 있는 효과와 하드웨어량이 감소되는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video printer apparatus and a method thereof. The heating period is variable in response to the temperature change of the TPH, including a temperature sensor for detecting the temperature of the thermal head and a temperature compensator for generating a strobe signal for controlling the heating period in response to the result of the temperature sensor and supplying the thermal head. In this case, the density of the color for each gray level is constantly expressed, thereby making it possible to print a high quality image and to reduce the amount of hardware.
