摘要： Recording an image of a holographic stereogram includes providing an optical deflecting device in proximity to a hologram recording medium that is exposed with a stripe-shaped elemental hologram. Either an object beam or a reference beam is deflected, in a long side direction thereof, through the optical deflecting device to expose the hologram recording medium. The hologram recording medium is multiply exposed, at least twice, with different deflection angles of the optical deflecting device to cause the stripe-shaped elemental hologram to have a plurality of parallaxes in a long side direction of the stripe-shaped elemental hologram.

摘要： An image exposure recorder for exposure-recording a holographic stereogram image or a hologram image on a recording medium for hologram. The recorder has an inverse correction system for rotating the polarization plane of a reference light (R) by means of a half-wave plate (11), directing the reference light (R) to a hologram recording medium (3), and measuring the intensity of a part of the reference light (R) transmitted through a polarizer (12) out of the reference light (R) transmitted through a part of the area of the hologram recording medium by means of a photodetector (13). In the inverse correction system, the angle of rotation of the half-wave plate is so determined that the intensity of the reference light (R) determined by the photodetector may be minimum or maximum. Therefore the degradation of the coherence between the object light and the reference light attributed to the transmission of the object and reference lights through the hologram recording medium having birefringence is prevented, and thus a holographic stereogram for reproducing a bright holographic stereogram image is fabricated.

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.
