Abstract

본 발명은 헤드의 부분적인 온도 상승으로 인한 손상이나 화질의 변화를 보상해 줄 수 있도록 한 감열기록헤드의 온도 보상장치 및 방법에 관한 것으로, 이러한 본발명은 헤드에 보내지는 데이터를 한 라인씩 비교하여 연속되는 흑도트를 검출하는 도트비교부(60)와, 라인메모리(7)를 구비하여 인접한 두 라인에서 검출된 흑도트를 서로 비교하고, 연속적인 흑도트와 새로 발생된 흑도트를 검출하여 같은 위치의 흑도트가 일정 라인이상 연속될 경우 그 다음 도트를 백도트로 만들어 그 부분의 헤드 온도를 내리게 된다.The present invention relates to a temperature compensating apparatus and method for a thermal recording head capable of compensating damage caused by partial temperature rise of a head or a change in image quality. The present invention compares data sent to a head line by line. A dot comparison unit 60 for detecting continuous black dots and a line memory 7 and comparing the black dots detected in two adjacent lines with each other, and detecting the continuous black dots and the newly generated black dots. If black dots in the same position are continuous over a certain line, the next dot is made back to lower the head temperature of the part.
