    Abstract: A vertical video format converter is disclosed including a memory unit which consists of a plurality of line memories to store input video data in one of the line memories, a filter for multiplying video data items respectively output from line memories by coefficients input into corresponding video data item positions and adding the multiplied data items to output filtered data. In the present invention, the position of the filter center value is not fixed, but can be located arbitrarily and the filter coefficients need not be symmetrical. Moreover, an interpolation may be performed by one-time filtering, resulting in faster data processing.
