PROBLEM TO BE SOLVED: To provide a computer hologram for displaying a three-dimensional multicolor (full-color) pattern, in particular, for displaying a bright image of high picture quality in accurate colors with reduced noise upon displaying a multicolor three-dimensional image which gives a parallax only in the horizontal direction. SOLUTION: The hologram has a long slit in a horizontal direction as a structural unit consisting of interference fringes computed for light at a desired wavelength, and the hologram comprises a plurality of slit groups, wherein each slit group includes a plurality of the above slits corresponding to various wavelengths arranged in the vertical direction, and each slit group is controlled in such a manner that a product of the wavelength and the main spatial frequency in a vertical direction of the interference fringes constituting the plurality of slits is constant.
