防偽點矩陣全像片色彩顯示與動畫設計之研究

Abstract

由於全像科技與數位資訊科技的進步，以往在平面上表現立體影像的全像術，得以用數位化點矩陣的方式更準確地表現全像影像，並製作出更多不同效果的全像片。而本研究的目的是將數位化點矩陣全像片的技術結合藝術創作與顯示科技，製作出具有動畫效果的彩色全像片，可不需顯示器及電源，即直接在平面載體上顯示動畫，並利用全像片的特性表現出特殊的視覺效果來達到防偽之功能。另外，以色彩學原理對全像片之色彩顯示作預覽模擬，除可瞭解點矩陣全像片之色彩變化外，並有助於全像片之設計。最後並結合數位半色調之資料隱藏技術，以達點矩陣全像片多重防偽之加值與應用。With the rapid advance of holography and computer technologies, effects such as three dimension and animation can be achieved by using dot matrix hologram which is designed in a digital manner. The objective of this research is to integrate dot matrix hologram, digital content and display technology to design color hologram with animation. It can directly display sequential images on hologram without power consumption. This special visual effect can provide unique anti-counterfeiting features. Additionally, using color theories to stimulate and to preview the color displayed from a hologram not only provides a better understanding of color variations, but also advances the design of hologram. Finally, the integration of hologram with data hiding by modified digital halftoning technique will have multiple anti-counterfeiting features and many potential value-added applications.
