Hologram color designation system and hologram color designation method based on dithering mask

Abstract

The present disclosure relates to a system and method for designating, for a hologram, a color to be implemented, by forming a certain pattern on a dithering mask, such that a hologram structure may express a particular structural color. To this end, the present disclosure may include an image obtaining unit configured to obtain an original image; an encryption unit configured to convert original colors of respective pixels included in the original image into encrypted colors, according to a predefined standard; a pattern data generation unit configured to generate, based on the encrypted colors, pattern data including dithering patterns corresponding to the respective pixels; and a pattern forming unit configured to form, based on the pattern data, a mask pattern on a dithering mask.

Dependencies are inferred from the claim text.
