Abstract: A video display method using a display apparatus for displaying a glasses free 3D video, the display apparatus including a display unit in which sub-pixels constituting pixels are arranged in a matrix, the video display method including: (a) displaying, in a row of sub-pixels of the display unit, a video in which a left-eye video and a right-eye video are disposed alternately in units of display each unit made up of n sub-pixels, where n is an integer equal to or greater than 2; and (b) detecting a distance from the display unit to a viewer, wherein in step (a), if the detected distance is different from a predetermined distance, the number of sub-pixels of at least one unit of display, among a plurality of units of display included in the row of sub-pixels, is varied as a function of the detected distance.

Abstract: An image processing device includes: a face detector which detects a face region including a face of a person from an input image signal; a determination portion which determines, in the input image signal of the face region, an addition amount of a pixel value to be added to the input image signal of the face region based on a size of a difference in a pixel value between adjacent pixels; and a signal corrector which adds the addition amount to the pixel value of the input image signal of the face region.

Abstract: A projector control apparatus that causes plural projectors to collectively project an image by individually projecting a different one of segment images into which the image is divided, the apparatus including: a spatial distribution information obtaining unit which obtains information indicating a distribution of one or more viewers that view the image in a space where the projectors are mounted; a mode selecting unit which selects, using the information indicating the distribution of the one or more viewers, one of modes including (i) a first mode in which a width of a projection area is a first width and (ii) a second mode in which the width of the projection area is a second width larger than the first width; and a projector control unit which changes arrangement of the segment images by controlling each of projection directions according to the mode selected.
