Abstract: The printed matter for regenerating a three-dimensional image derived from a parallax image string obtained on interpolating shape changes between images constituting the parallax image string is to be produced. An image printing device 1 morphs images constituting a plurality of sets of parallax image strings of an object obtained on photographing by an image pickup device 30. Based on the morphed parallax image string, the printed matter regenerating a three-dimensional image is formulated by the printer 50. The image printing device 1 executes processing in which the morphing rate of change is changed depending on the actuation of the actuating unit 100 to display the resulting image on the display unit 40. The image printing device 1 also morphs the image of the object photographed by the image pickup device 30 with an image stored in the external memory 80.

Abstract: 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.
