Abstract
비디오 영상내의 각각의 상이한 칼러에 칼러값이 할당된 디지탈 비디오 영상 프레임에 대한 픽셀 칼러값을 인코딩하는 방법이 기재되어 있다. 영상 프레임에 특출한 칼러가 인식되고, 제1실시예에서, 특출한 칼러와는 다른 칼러를 갖는 각각의 픽셀이 그 각각의 칼러값(0010 내시 1111)에 따라 개별적으로 인코드되며, 특출한 칼러에 대한 3 또는 그 이상의 연속적인 픽셀의 런이 런 렝스 인코드된다. 장치에서 그 나타나는 런과 유사한 부가 코드(0000 0011)가 제공되어, 프레임 과정동안에 지정된 특출한 칼러에서의 변화를 허용한다. 다른 실시예에서, 모든 칼러의 런은 런 렝스 인코드되지만, 특출한 칼러에 대한 더 짧은 코딩 설계는 그렇지 않으며, 다른 실시예에서는 특출한 칼러의 범위가 좁다. 이들 코딩 설계에서 사용되는 원리는 영상 재료의 클래스를 위한 코딩의 효율성을 개선시킨다.A method of encoding a pixel color value for a digital video image frame in which a color value is assigned to each different color in a video image is described. Colors that are outstanding to the image frame are recognized, and in the first embodiment, each pixel having a color different from that of the color is encoded individually according to its respective color value (0010 eunuch 1111), and the color is exceptional Runs of 3 or more consecutive pixels for are run length encoded. An additional code (0000 0011) similar to the run that appears in the device is provided to allow for changes in the specified color specified during the frame process. In other embodiments, all color runs are run length encoded, but shorter coding designs for particular colors are not, and in other embodiments the range of exceptional colors is narrow. The principles used in these coding designs improve the efficiency of coding for classes of image materials.
