ABSTRACT:
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.
