摘要： An image data generating method for generating image data corresponding to a planar holographic stereogram is provided. First, an object or imaging device is rotated, while the distance between the object and the imaging device is kept substantially constant, for shooting plural images of different viewing angles by the imaging device. The image data of plural images is then corrected for keystone distortion. The image data corrected for keystone distortion is then processed with viewing point conversion processing for converting the viewing point for generating image data of images recorded on the holographic stereogram. In addition, image data including the information for plural images is compressed for storage in the internal storage device of the computer. With the image data having been read into the internal storage device, only the image data of an image required for image data conversion processing of generating image data of the image recorded on a holographic stereogram is expanded for executing image data conversion processing operations.

摘要： In a system in which images having parallax data, and which are made up of plural images containing the parallax information, are processed with viewing point conversion, and the resulting new images having parallax data are used, as in a system of generating a holographic stereogram, a unit for generating the images having parallax data is to be independent from other unit or units. To this end, the information necessary to perform viewing point conversion processing of converting the viewing point for an object is attached to images having parallax data when the images having parallax data have been produced. When the images having parallax data is exchanged between the unit for generating the images having parallax data and other unit or units, the exchanged images having parallax data need to be those to which the information has been attached.

摘要： A method and an apparatus for creating a holographic stereogram are provided for canceling noises localized to infinity and offering a high-quality hologram. The creating method is executed to display an image corresponding to a coordinate location on the hologram recording medium on the display unit, condense the laser beam transmitted through the display unit as an object beam at the coordinate location of the hologram recording medium, and apply part of the laser beam before transmission through the display unit as a reference beam onto the hologram recording medium, for sequentially forming stripped or dotted holographic elements on the hologram recording medium. The creating apparatus includes a first diffuser panel located close to the display unit, a mask, and a second diffuser panel, the latter two of which are located immediately before the hologram recording medium. The mask has an opening corresponding to the width of the holographic element. The second diffuser panel serves to one-dimensionally diffuse the object beam transmitted through the opening of the mask. The first diffuser panel is relocated at the exposure of each holographic element.

摘要： In generating a parallax image string used for generating a holographic stereogram, the image quality of a stereoscopic image generated from the parallax image string is to be maintained as the time needed in imaging the parallax image string is shortened. To this end, an optimum number of image frames of each of plural parallax image strings are photographed in agreement with the localized position of the reproduced image of a generated holographic stereogram. The image processing is executed for equating the numbers of frame images of the parallax image strings. The parallax image strings having the equal number of the frame images of the parallax image strings are synthesized by, for example, chroma key synthesis to generate a new parallax image string.
