  • Publication number: 20100129739
    Abstract: A surface position detection apparatus capable of highly precisely detecting the surface position of a surface to be detected without substantially being affected by relative positional displacement due to a polarization component occurring in a light flux having passed through a reflective surface. In the apparatus, a projection system has a projection side prism member (7) having first reflective surfaces (7b, 7c), and a light receiving system has a light receiving prism member (8) having second reflective surfaces (8b, 8c) arranged in correspondence with the projection side prism member. The surface position detection apparatus further has a member for compensating relative positional displacement due to a polarization component of a light flux having passed through the first and second reflective surfaces.

    Abstract: A print-ordering system and a print-ordering method that can select image processing preferred by a user via a network and generate an appropriate print preferred by the user. The image processing preferred by the user can be selected via the network. Image data and order information are transmitted from a user terminal such as a PC to the server of a print system via the network. In a print-service system for placing a print order, the user can make desired settings on the image processing performed when executing printing via the network. Here, the details on the settings include outline emphasis, hue, color density, gradation, and contrast (the blueness of the sky, the color tone of a human skin, etc.) Further, a plurality of images is generated in the server by subjecting an order image to multilevel processing for each item of the settings and the images are transmitted to the user terminal so that the images are produced by the user terminal.
