  • Patent number: 7194703
    Abstract: A system for creating screen savers based on video images is provided. An object image that may move around in a video image is separated from backgrounds. An MPEG-4 file of the video image is created and stored in a computer. The MPEG-4 file is uploaded from the computer to a server connected to the computer through a network. The server detects motions of the object image in the MPEG-4 file, creates a screen saver based on the detected motions, and stores the screen saver. The computer may download the screen saver stored in the server and install the screen saver on the computer, and displays the video image as the screen saver on a screen.

  • Patent number: 5923824
    Abstract: A color processing method utilizing a plurality of devices having different color spaces as one virtual device. A scanner inquires a computer of color space and presence/absence of a color conversion function. If the computer has the color space conversion function, the scanner transmits color image data with parameters for converting the data into data of the color space of the computer. Inversely, the computer inquires the printer of color space and presence/absence of a color space conversion function. If the printer has the color space conversion function, the computer transmits color image data with parameters obtained from operation of parameters for converting the color space of the image data into the color space of the printer and the parameters received from the scanner.
