1. A display apparatus that displays one image plane using plural projection type image display devices, wherein:
- the plural projection type image display devices that together form the display apparatus are disposed in such a manner that at most one projection type image display device among the plural projection type image display devices forms a projection region of an original shape of projection on a screen;
the plural projection type image display devices are disposed in such a manner that a ratio between a maximum value and a minimum value of maximum luminance on the screen of each pixel of a projected image from each projection type image display device is a predetermined value or larger; and
the ratio between the maximum value and the minimum value of the maximum luminance of each pixel is such that a maximum value of luminance is nearly twice or larger a minimum value of luminance.

5. A display apparatus that displays one image plane on a screen using at least first and second projection type image display devices, wherein:
-
let P1 be a pixel of the first projection type image display device corresponding to a position at a particular screen coordinate Ps included in a superimposed region in which projection regions formed on the screen by the first and second projection type image display devices are superimposed, and let P2 be a pixel of the second projection type image display device corresponding to the position at the screen coordinate Ps; each projection type image display device is disposed with respect to the screen in such a manner that a differential vector on the screen, DP1=(P1′
−
P1), between the pixel P1 of the first projection type image display device and at least one pixel P1′
adjacent to the pixel P1 is different from a differential vector on the screen, DP2=(P2′
−
P2), between the pixel P2 of the second projection type image display device and a pixel P2′
adjacent to the pixel P2;the at least first and second projection type image display devices are disposed in such a manner that a ratio between a maximum value and a minimum value of maximum luminance on the screen of each pixel of a projected image from each projection type image display device is a predetermined value or larger; the ratio between the maximum value and the minimum value of the maximum luminance of each pixel is such that a maximum value of luminance is nearly twice or larger a minimum value of luminance.

6. An image information generating method adapted to a display apparatus for generating image information given to respective projection type image display devices that together form the display apparatus that displays one image plane using plural projection type image display devices, the method comprising:
-
generating plural sub-regions by dividing the screen; acquiring resolution of each projection type image display for each one of the sub-regions obtained by dividing the screen; and allocating a pixel value to a pixel of each projection type image display device corresponding to a sub-region of interest, first from a projection type image display device judged as having lowest resolution for the sub-region of interest. - View Dependent Claims (7, 8)
