Device and method for converting an aspect ratio of a video signal, is disclosed, in which an aspect ratio of an image at an arbitrary position can be converted to an arbitrary value, the device including means for generating arbitrary mapping information on the received image in image block units defined by the horizontal, and vertical sections, and means for determining the aspect ratio of the received image for a block using the arbitrary mapping information and converting the received image, varying a vertical display ratio for each horizontal position and/or a horizontal display ratio for each vertical position, of the received image with the aspect ratio, and the method including the steps of generating arbitrary mapping information on the received image in image block units defined by the horizontal, and vertical sections, and determining the aspect ratio of the received image for a block using the arbitrary mapping information and converting the received image, varying a vertical display ratio for each horizontal position and/or a horizontal display ratio for each vertical position, of the received image with the aspect ratio.
