摘要:
An apparatus for generating a parallax image to be used for a display of a three-dimensional image on a three-dimensional integral imaging display includes an image signal acquiring unit, an image signal assigning unit, and a parallax image generator. The image signal acquiring unit acquires a plurality of image signals by picking up an image of an image object from a plurality of different parallax directions. The image signal assigning unit assigns an output order of the plurality of image signal so that the plurality of image signals are arranged in a reverse parallax direction order to an order of beam directions of the three-dimensional integral imaging display. The parallax image generator generates a parallax image from the plurality of image signals to which an output order is assigned by the image signal assigning unit.

A stereoscopic image producing method can produce a stereoscopic image efficiently. The stereoscopic image producing method includes inputting a plurality of parallax images with pixel data including information pieces about the three primary colors, which are produced from different viewpoints, and, based upon information about arrangement of color pixel dots constituting a pixel of a display screen which displays a two-dimensional image thereon, composing some pieces of the three primary color information pieces in each of the parallax images and allocating the three primary color information pieces for different ones of the parallax images to the color pixel dots adjacent to each other in a screen horizontal direction on the display screen, where a stereoscopic image including a plurality of different parallax image information pieces in a horizontal direction in a space in which the stereoscopic image is displayed is produced.

An apparatus includes a stereoscopic display region calculator calculating a stereoscopic display region to reproduce a three-dimensional positional relationship in image data displayed on a stereoscopic display device, based on two-dimensional or three-dimensional image data, a position of a target of regard of a virtual camera set in processing of rendering the image data, and orientations of the light beams output from the stereoscopic display device. The apparatus also includes an image processor performing image processing on image data outside a region representing the outside of the stereoscopic display region calculated by the stereoscopic display region calculator. The image processing is different from image processing on image data inside a region representing the inside of the stereoscopic display region. The apparatus also includes an image generator generating stereoscopic display image data from the two-dimensional or three-dimensional image data after processed by the image processor.

摘要:
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.
