| Outline of Final Research Achievements |
In order to establish a method capable of protecting images displayed on a liquid crystal display (LCD), this study proposed a method of switching two images of different colors on the LCD and constructed a method to create two images for switching. A combination of colors not causing flicker at the time of switching became clear. A method of selecting two colors that can display the target color without flicker and a method of modifying the color in the original image to the shape of the letter to create two images were constructed. When two images created are switched on the LCD, it is confirmed that letters appear in the image captured by the digital camera though the image of the same color as the original is perceived.
