영상 전화기의 이동 검출장치에 있어서, 포매터로부터 블록 단위 형태의 입력 데이터를 받아 리드/라이트하기 위한 BM장치(BM)와, 프레임 메모리로부터 서치영역에 해당되는 데이터를 받아 이동검출시와 예측시에 사용하기 위한 SAM장치(SAM)와, 상기 BM장치(BM)로부터 클럭 메모리 데이터를 받아 차이를 계산하고 절대값을 취하여 한 서치 포인트에서의 왜곡을 계산하기 위한 산술장치(AU)와, 상기 산술장치(AU)로부터 상기 계산된 서지 포인트에 대한 왜곡데이타와 비교하는 비교기(COP)와, 상기 서치영역에서 앞으로 왜곡을 구하게될 소정의 한 서치 포인트 블록의 어드레스를 결정하기 위한 서치 포인트 결정장치(SPD)와, 프로그램데이타에의해 상기 BM장치(BM)장치를 제어하여 한 서치 포인터에서 왜곡 및 예측을 위하여 데이터를 리드/라이트할 제어신호를 발생하고, 상기 산술장치(AU)의 계산된 서치 포인트 왜곡데이타를 저장키 위해 클럭신호를 공급하며, 각 스텝의 결정과 이동백터 검출의 완료를 알리고 예측을 위한 제어데이타를 출력하는 제어기(CON)로 구성됨을 특징으로 하는 영상전화기에 있어서 이동검출장치.In the movement detection device of a video telephone, a BM device (BM) for receiving / reading block-type input data from a formatter and receiving data corresponding to a search area from a frame memory is used for movement detection and prediction. A SAM device (SAM), an arithmetic device (AU) for receiving clock memory data from the BM device (BM), calculating a difference, and taking an absolute value to calculate distortion at one search point, and the arithmetic device ( A comparator (COP) for comparing the distortion data for the calculated surge points from AU), a search point determining device (SPD) for determining the address of a predetermined search point block for which distortion is to be found in the search area in the future; Program data to control the BM device (BM) to generate a control signal to read / write data for distortion and prediction from a search pointer. And supplying a clock signal to store the calculated search point distortion data of the arithmetic unit (AU), informing the completion of the determination of each step and the detection of the moving vector, and outputting control data for prediction. Mobile detection device in a video telephone, characterized in that configured. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
