DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. (Embodiment 1) In a three-dimensional image recording medium 100 according to a first embodiment of the present invention, as shown in FIG.
By applying pressure to zero, it can be deformed into a predetermined shape. As the foamed layer 1, foamed PET (polyet
A material that can be deformed by applying pressure, such as hylene terephthalate), is used. Also, on the foam layer 1,
An image receiving layer 2 for improving the fixability of an ink such as a pigment or a dye recorded by the image recording means 3 is provided, and a support 12 is provided below the foamed layer 1.

Next, the three-dimensional image recording apparatus 200 according to the first embodiment uses, for example, an ink-jet printhead or a fusion-type or sublimation-type thermal head to store the three-dimensional image data 9 in the three-dimensional image recording medium 100. An image recording means 3 for recording, a pressing roller 4 for deforming the three-dimensional image recording medium 100 and an opposing roller 5 for displaying the image recorded on the three-dimensional image recording medium 100 as a three-dimensional image are provided.

Next, a procedure for forming a three-dimensional image in the three-dimensional image recording apparatus according to the first embodiment will be described with reference to FIGS.
5 will be described. First, the shape and the like of the pressing roller 4 necessary for recording a stereoscopic image will be described. The pressing roller 4 deforms the foam layer 1 of the three-dimensional image recording medium 100 by a foam layer deforming unit, and converts an image recorded on the image receiving layer 2 into an image.
In order to display a stereoscopic image having a depth due to parallax, it is assumed that the image has a cross-sectional shape as shown in FIG. The pressing roller 4 is formed of metal or resin having a strength enough to withstand a pressing force required to deform the three-dimensional image recording medium 100.

Further, when the image acquired by the image acquiring means is recorded on the three-dimensional image recording medium 100 by the image recording means, the image is first recorded on the image receiving layer 2. In order to create a three-dimensional image with a sense of depth from the image, the outer peripheral surface of the pressing roller 4 is
The shape is such that the left and right eyes restrict the images that can be seen from each other. That is, the shape is such that the images that can be seen by the right and left eyes are different. Therefore,
The recorded image data recorded on the three-dimensional image recording medium 100 includes three-dimensional image recording area groups 6 (6-1,..., 6-7) and 6 ′ (6′-) as shown in FIG. 1,..., 6′-7) requires stereoscopic image data 9 in which a strip image viewed with the right eye and a strip image viewed with the left eye are recorded alternately.

Further, as shown in FIG. 3, two viewpoints A and B corresponding to the left and right eyes are provided at a position separated by a predetermined length in the vertical direction from the surface of the recording medium, and are equally spaced on the surface of the recording medium. Draws a line connecting the point group C separated by, and the two viewpoints A and B, and intersects the two lines drawn on the recording surface from the two viewpoints, on both sides sandwiching the mountain-shaped vertex If the images to be displayed on the left and right eyes are recorded, the images cannot be seen by the eyes adjacent to each other, and a three-dimensional display is possible. At this time, the side surface of the mountain shape is moved to the stereoscopic image recording area group 6 (6-1, ..., 6-
7), 6 '(6'-1, ..., 6'-7). The positions of the viewpoints A and B can be arbitrarily determined according to the intended use of the present recording medium.

, 6 ′ (6′-1,..., 6′-7) are more unevenly stretched than before deformation. Further, the image recorded on the three-dimensional image recording medium 100 before deformation has a problem that the image is stretched by deformation and the density of the image is reduced.

Therefore, a strip-shaped image corresponding to the above-mentioned recording width is created, and the density of the strip-shaped image which is greatly expanded by deformation is increased. After the image processing is performed by the image processing means, the two pieces of strip-shaped image data 8 (8-1,..., 8-7), 8 '(8'-1,
.., 8′-7) are combined into one, as shown in FIG.

A series of operations for forming a three-dimensional image is performed by first taking two images obtained from two viewpoints using an image input device such as a video camera, and performing processing on a computer via a video capture device or the like. And converts the two image data obtained here into a plurality of strip-shaped image data by the image processing means.
After dividing into 8-1, ..., 8-7,8'-1, ..., 8'-7, the strip images from two viewpoints are 8-1,8'-1,8 -2,8'-2, ・ ・ ・
