Abstract

본 발명은 멀티 모드시 모드와 모드사이에서 컨버젼스를 실행하기 위해 보간을 실시할 때 모드와 모드사이의 차이값을 구하고 그 차이값을 선형 보간한 후 최종 모드로 변경하여 보다 빠른 모드 변환이 이루어지도록 한 디지탈 컨버젼스를 위한 모드 변환방법에 관한 것이다. 이러한 본 발명은 실제 가장많이 사용되는 모드를 기준 모드로 설정하고 현재 모드와 기준 모드를 비교하는 제1과정과; 비교결과 현재 모드와 기준 모드가 다를 경우 현재 모드에서 기준 모드를 감산한 차이값을 1차보간하는 제2과정과; 기준 모드를 4차 보간한 데이터와 제2과정에서 얻어지는 차이값을 가산한 후1차 보간으로 확장하여 화면에 디스플레이 하는 제3과정을 순차 실행시키게 된다.In the present invention, when interpolation is performed to execute convergence between modes in multi-mode, the difference between the modes and modes is obtained, the interpolation is performed linearly, and the mode is changed to the final mode for faster mode conversion. A mode conversion method for a digital convergence. The present invention comprises the first step of setting the most frequently used mode as the reference mode and comparing the current mode and the reference mode; A second process of first interpolating a difference value obtained by subtracting the reference mode from the current mode when the current mode and the reference mode are different from each other; After adding the data obtained by the fourth interpolation of the reference mode and the difference value obtained in the second process, the third process of sequentially expanding the first mode to display on the screen is performed.
