摘要:
An image recording medium in which a refractive index modulation is recorded in a material in a layer such that, when the hologram recording medium is illuminated from a predetermined angle and a viewpoint is moved horizontally with respect to a normal line, a hologram image having continuous parallax in at least the horizontal direction is reproduced and that, when the viewpoint is moved in a direction with respect to the normal line different from the horizontal direction, another image that is different from and thus is not continuous with the hologram image is reproduced.
