Abstract: A video output device that is capable of luminance adjustment while preventing signal degradation includes a display unit which respectively displays a left eye image that is transmitted to the left eye and a right eye image that is transmitted to the right eye and which also outputs, by insertion between the left-eye image and the right-eye image, a black image that lowers luminance and does not contribute to the display, and a control unit that controls and adjusts the luminance by adjusting an insertion time of the black image inserted between the left-eye image and the right-eye image displayed on the display unit.

Abstract: An apparatus includes a detecting section for detecting a brightness level of a screen image of a video signal as an area brightness level for each of a plurality of display areas on a display screen; and an adjustment driving section for comparing the area brightness levels with each other and driving the display device by a driving signal representing the screen image so as to form a brightness level distribution of the screen image according to adjustment characteristics determined in accordance with the difference between the area brightness levels.

Abstract: A display apparatus for a television having a screen of an aspect ratio different from that of an original image, wherein an image is distorted in at least one of the vertical and horizontal directions such that an expansion ratio or a reduction ratio gradually changes, and the distorted image is displayed on the screen. With the display apparatus, an image with a different aspect ratio can be displayed on the whole screen with minimally reduced missing image portions and distortion. Also, a vista size image can be displayed with an impression that a zoom-up effect is emphasized, while missing image portions are minimally reduced in left and right side portions.
