In an image display apparatus, the sub-pixel areas which are correspondingly assigned to the optical apertures are defined according to an observation position of a viewer, and the sub-pixel areas includes sub-pixel segments into which the sub-pixel positioned at a boundary between adjacent sub-pixel areas is separated. The sub-pixel segments correspond to the adjacent sub-pixel areas and are observed via adjacent optical openings. The sub-pixel display information obtained by mixing parallax information belonging to the adjacent sub-pixel areas is displayed in the sub-pixel including the adjacent sub-pixel segment.

Three-dimensional image display apparatus for displaying three-dimensional image

In a stereoscopic image imaging method which captures an image of an object to be displayed as a stereoscopic image, a three-dimensional image is generated in real time from multi-viewpoint images captured by a multi-camera, and is displayed on a viewer provided to the multi-camera, thus allowing a photographer to adjust an imaging condition. The photographer is informed of parameters, which implements a display state adjusted by an observer of a three-dimensional display while observing the three-dimensional image, via the viewer, and the photographer can capture appropriate multi-viewpoint images.

Stereoscopic image display apparatus

When displaying one of a three-dimensional image and a two-dimensional image on a background and displaying the other image in a window, a flag bit indicating whether the first and second electrodes overlap the window is set. Waveforms differing according to the flag bit are applied to the first and second electrodes as pulses applied to the opposed first and second electrodes of a variable polarization cell. As a result, three-dimensional image display is partially conducted in the window and two-dimensional image display is conducted in areas other than the window.

Exit pupils of the array correspond to the respective element images. The horizontal pitch of the exit pupils or an integral multiple of the horizontal pitch is set equal or slightly smaller than an integral multiple of the horizontal pitch of pixels.
