Abstract: This invention discloses a method of protecting copyright of a digital video work by using a digital password technology and a digital watermark technology to prevent the unauthorized use of a digital video work. Such method adds password protection of two chrominance arrays of such video work in advance, so that when such video work is published on the Internet, it can only be played in color by a specified player. As long as a user enters the correct password into the specified player, a full color visual effect of such video work can be obtained. If other players are used to play such video work, only a partial gray-scale visual effect can be obtained. Users must request or buy a specific player and a password from the distributor of such video work to play the complete information to prevent piracy.

Abstract: A method for converting monochrome images to color images. A monochrome image is blocked first, and pixel values of monochrome image blocks are obtained by statistical analysis. The monochrome image is then processed by layered mapping and color values of equal grayscale layers thereof are obtained. Finally, each monochrome image block is matched to a color of a corresponding equal grayscale layer.

Abstract: The present invention discloses a method of personalizing icons on an electronic communication product, comprising the steps of installing an image processing program into an electronic communication product, executing the image processing program to edit any icon on the screen of the electronic communication product; connecting an input device (such as a keyboard or a light pen) to the electronic communication product to click on the icon; and selecting the type of desired effect on the original icon; and displaying the edited icon on the screen of the electronic communication product. Such method is applicable for an electronic communication platform of handheld computers such as a handset and a personal digital assistance (PDA).

Abstract: This invention discloses a method of protecting copyright of a digital video work by using a digital password technology and a digital watermark technology to prevent the unauthorized use of a digital video work. Such method adds a password into two color matrixes of such video work in advance, so that when such video work is published on the Internet, it can be played by a specified player. As long as a user enters the correct password into the specified player, a full visual effect of such video work can be obtained. If other players are used to play such video work, only partial gray-scale visual effect can be obtained. Users must request or buy a specific player and a password from the distributor of such video work to play the complete information to prevent piracy.
