Abstract
A video display device is provided with a video conversion circuit for extending an inputted video signal in horizontal and/or vertical directions, and a display unit including a display screen whose aspect ratio is longer in the horizontal direction than 16:9 and adapted to display the video extended by the video conversion circuit. The video conversion circuit includes a mode for extending the inputted video at a scaling factor of A, which is equal to or larger than 1, in the horizontal direction and at a scaling factor of B, which is equal to or larger than 1, in the vertical direction, so that videos effectively utilizing the aspect ratio of the video display device can be displayed while reducing incongruous feeling caused by the extension in the horizontal direction. Thus, an increase in the number of screen modes can be minimized, and modes capable of giving a remarkable sense of presence and modes capable of displaying right circles can be provided in the video display device with an aspect ratio of, e.g. 10:3.
