摘要： A video data interpolating apparatus which is capable of readily processing a large number of interpolation data trains. The apparatus is provided with a plurality of pairs of buffer memories, each pair consisting of two buffer memories adapted to alternatively temporarily store video data trains which are successively given, and an Interpolation circuit. Video data being given is successively written into one of the buffer memories which constitute each of the first and second buffer memory pairs. Keeping pace with this writing operation, the video data train which immediately precedes the data which is being written is read out from the other buffer memory of the second buffer memory pair. Interpolation is carried out between this read data and the video data which is being given, thereby obtaining one or several interpolated video data items. This interpolated video data is written into one of the buffer memories which constitute each of the third buffer memory pral and the buffer memory pairs which are subsequent thereto. in parallel with such writing and reading operations in relation to each of the buffer memory pairs, the value stored in the other memory buffer of each of the first and third buffer memory pairs and the buffer memory pairs subsequent thereto is read out and stored in a video memory.
