Abstract: A parallax composite image displayed by image display means may be observed as predetermined parallax image at predetermined position by reflecting and guiding light from light source means and by using a diffusion pattern in which diffusion patterns are engraved at predetermined intervals to diffuse and transmit incident light on the diffusion pattern to the image display means. A fine notched structure is provided to cyclically and symmetrically vary the diffusion patterns in the horizontal direction. A structure is provided to control an amount and range of blur of pixels visible through light diffused toward the image display means by the diffusion pattern to which recesses and protrusions are added. By evaluating and adjusting a cycle of the notched structure so as to be appropriate, resultant adverse effects from the notched structure itself may be suppressed. Bright-dark patterns having a relatively long cycle may be reduced without increasing crosstalk.

Abstract: Many pixels (11) are laid out in horizontal and vertical directions on liquid crystal panel (10). There is black matrix (12) between them not to display images. Lenticular lenses (20) are set so that lenticular lenses are inclined at a predetermined angle to vertical direction of liquid crystal panel.

In this way, straight line connecting lower right vertex of target pixel to lower left vertex of immediately right pixel angularly coincides with the lenticular lenses. Consequently, brightness on a screen visible through lenticular lenses becomes constant irrespective of position of observer, which results in reduced moire.

Abstract: A three-dimensional sense adjusting unit displays three-dimensional images to a user. If a displayed reaches a limit of parallax, the user responds to the three-dimensional sense adjusting unit. According to acquired appropriate parallax information, a parallax control unit generates parallax images to realize the appropriate parallax in the subsequent stereo display. The control of parallaxes is realized by optimally setting camera parameters by going back to three-dimensional data. Functions to realize the appropriate parallax are made into and presented by a library.
