Abstract

본 발명은 서브 샘플링된 신호의 보간을 위한 영상 메모리 시스템과 관련된 것으로 종래에는 이러한 메모리 시스템이 IDTV나 EDTV등의 전용 메모리로 설계되어지거나 각 보간신호 데이타를 동시에 융통적으로 얻는데 제약이 있어서 바람직한 것이 못되었으나, 본 발명에선 NTSC의 대역 압축 방식에서 신호보간을 위한 각종 신호의 형태를 저장한 메모리와, 이 메모리로 부터 복수 보간신호를 동시에 얻어낼 수 있도록 각종 보간신호를 저장하고 있는 이것을 홀, 짝수 라인별로 저장시킨 제1-제4 메모리(M1-M4:15-18)와, 이 제1-4 메모리(M1-M4)로 부터 다수 보간신호를 동시에 선별하여 출력할 수 있도록 제어하는 영상메모리 제어부(14)를 일체로 포함한 구성의 서브 샘플링 신호의 보간을 위한 영상 메모리 시스템을 제공하는데 있다.The present invention relates to an image memory system for interpolation of sub-sampled signals. In the related art, such a memory system is designed as a dedicated memory such as IDTV or EDTV, or has limitation in obtaining each interpolation signal data flexibly. However, in the present invention, in the NTSC band compression method, a memory storing various types of signals for signal interpolation, and various interpolation signals are stored so that multiple interpolation signals can be simultaneously obtained from this memory. Controlling so that a plurality of interpolation signals can be simultaneously selected and output from the first to fourth memories M 1 to M 4 : 15-18 and the first to fourth memories M 1 to M 4 . An object of the present invention is to provide an image memory system for interpolating subsampling signals having an integrated image memory control unit (14).
