Abstract
An aspect ratio converter converts the input aspect ratio of an input video signal to an output aspect ratio. The input video signal contains partial area information representing a portion of the input video signal which constitutes substantially all of the video picture with the desired output aspect ratio. The input video signal is stored in an addressable memory and is read out from those addresses corresponding to the partial area of the input video signal.
