IPC: G06T1/00
Filed: 1998-03-25
Abstract: 본 발명의 시스템과, 방법과, 프로그램은 동일한 컬러값(예를 들면, L * a * b * 값)을 가짐으로써 외부적으로 정의된 4 가지 염료 조합(CMYK)과 등가인 주어진 프린터의 4 가지 염료의 유일한 조합(C'M'Y'K')을 결정한다.    외부적으로 정의된 4가지 염료 조합(CMYK)의 값인 0과 동일한 4 번째 요소값(K)을 갖는 각각의 3 가지 요소 조합(CMY)과 연관된 L * a * b * 값이 역변환/보간(interpolation) 프로그램에 사용된다.    프린터는 또한 4 번째 염료 K가 0인 프린터의 3 가지 염료의 사전설정된 가변 조합 (CMY)p의 매트릭스를 프린팅한다.    각각의 프린팅된 패치들에 대해서 L * a * b * 값이 측정된다.    이 값과 대응하는 3 가지 염료 조합값이 역변환/보간 프로그램으로 입력된다.    외부적으로 정의된 임의의 주어진 3 가지 염료 조합(CMY) 혹은 L * a * b * 값에 대하여, L * a * b * 값을 일치시킴으로써 역변환/보간 프로그램으로부터 프린터의 대응하는 3 가지 염료 조합(C'M'Y')이 결정될 수 있다.    다음에, 외부적으로 정의된 4 가지 염료 조합의 4 번째 염료, 예를 들면 검정(K)이 컬러값(예를 들어, L * )을 일치시킴으로써 프린터의 4 번째 등가 염료(K')로 매핑된다.    예를 들면, C=0, M=0, Y=0인 경우에 표준 테이블을 통해 4 번째 염료의 여러 가지 퍼센트에 대하여 L * 값이 발견된다.    4 번째 요소의 변화하는 퍼센트를 프린팅하고 이의 L * a * b * 값을 측정하며 a * 와   b * 를 거의 0인 것으로 가정하고 L * 값을 사용함으로써, 프린터의 4 번째 염료에 대한 여러 가지 퍼센트에 대해서 L * 값이 발견된다.    이와 같이, 변환은 CMY에서 C'M'Y' 및 K에서 K'와 같이 두 개의 단계로 발생된다.    두 개의 단계가 결합되면, CMYK가 C'M'Y'K'로 전환된다.    따라서, 3 차원간 변환 및 별도의 1 차원간 변환을 사용하여 유일한 해를 구한다.

Abstract: PURPOSE: A loop back device and the method are provided to perform a point-to-point control loop back, even though a subscriber signal is not delivered. CONSTITUTION: A loop back device using a random pattern in an N 64KBPS high speed data network comprises: a random pattern generator(1) for generating an X6+X4+1 random pattern; an inversion section(2) for outputting and selecting the random pattern as a loop back request signal or a loop back release signal, by control of a loop back selection signal; a data selection section(3) for selecting and transmitting one of signals outputted from the inversion section and main data, by the control of the data selection signal; a serial/parallel data storage circuit(4) for storing the data from the data selection section(3), by converting the data in serial; a loop back observing section(5) for examining whether the X6+X4+1 loop back pattern is correct from the stored data; a loop back release observing section(6) for observing the loop back release signal; a loop back latching section(7) which a loop back request is latched and maintained, when the loop back request signal is entered for regular time; a loop back performing section(8) for performing a loop back function; a same data observing section(9) for preventing an error of the loop back pattern; and a control clock section(10) for generating/controlling a clock necessary for a system from a reception clock.
