Multiple image display device and image display device
In a multiple image display device that is provided with a plurality of image display devices and that displays a single input image, the image display devices each divide the input image into division images that are individually displayed on the image display devices, and enlarge and display them. In particular, the image display device provided in an edge portion of the multiple image display device enlarges the division image toward a side opposite from the side of the edge portion. In this way, the edge portion of the input image is displayed on the multiple image display.
1. A multiple image display device array comprising:
an array of display devices arrayed in horizontal and vertical direction, each display device having a housing portion surrounding a display portion;
a division portion dividing a single input image into division images that are displayed on the array of display devices; and
an enlargement portion enlarging the division images obtained in the division portion, wherein,
the division images are enlarged horizontally based on a horizontal enlargement factor TH, and enlarged vertically based on a vertical enlargement factor, Tv, where
TH= 1 +l ˜×(m−1)/( LH×m ) and
Tv= 1+ Kv ×( n− 1)/( Lv×n ),
the enlargement portion enlarges each division image so that the division image protrudes from the display portion toward the one end and the other end by the ratio of (i−1)/(m−1) to (m−i)/(m−1) in the horizontal direction and (j−1)/(n−1) to (n−j)/(n−1) in the vertical direction, wherein
“KH” equals a distance between the right side of the display portion of a first display device and the left side edge of the display portion of a second display device positioned on the right side neighbor of the first display device in the display device array,
“Kv” equals a distance between the lower side edge of the display portion of a first display device and the upper side edge of the display portion of a third display device positioned on the lower side neighbor of the first display device in the display device array,
“LH” equals the length of the horizontal side edge of the display portion,
“Lv” equals the length of the vertical side edge of the display portion,
“m” represents a number of image display devices provided in the horizontal direction,
“n” represents a number of image display devices provided in the vertical direction
“i” represents a horizontal position of each image display device, and
“i” represents a vertical position of each image display device.
