Abstract: An apparatus displaying a three-dimensional image is provided with a parallax barrier having optical openings arranged at a horizontal pitch n times as large as that of pixels arranged on a display surface. The parallax barrier reproduces rays from every n pixels on the display surface in a horizontal direction and no vertical parallaxes is displayed in a viewing area. Image data for a three-dimensional image is processed so as to be recorded in an efficient saving format which minimizes the degradation of image quality while accomplishing a high compression rate. Image data from a set of pixels constituting parallel rays in the same parallax direction are accumulated to obtain more than n parallax component images. Parallax component images corresponding to n-th adjacent parallax directions are combined together and thus converted into n connected images having the same numbers of vertical and horizontal pixels.

Abstract: In a three-dimensional image display apparatus in which a lenticular plate and shutter device are arranged in front of a display module, one frame image is displayed using n field images. To display each field image, a shutter device is driven to substantially simultaneously open a group of shutter elements for every n lenses along a horizontal direction. Thus, light beams are transmitted from lenses through the shutter elements to an observing zone. The group of the opened shutter elements is sequentially changed in response to n switchings of the field. The switching of shutter elements is synchronized with the pixels on the display surface sequentially rewritten from top to bottom by linear sequential driving during the switching of the field. The elemental image is projected on the viewing zone via the lenses and the shutter elements.
