  • Patent number: 7724298
    Abstract: The present invention relates to an image processing system and an image processing method, an image pickup apparatus and an image pickup method, and an image display device and an image display method, which can faithfully pick up and display the colors of an object. Slit light of an optical image of the object that has passed through a slit 42 is divided into a spectrum by a light divider 43. A light sensor 44 outputs image data based on the spectrum of the slit light of the optical image of the object. A micromirror array 74 causes the exiting of reflection light formed by extracting spectrum portions based on the image data from a spectrum of incident white light from a light divider 73. The spectrum portions of the reflection light exiting from the micromirror array 74 are synthesized by a spectrum synthesizer 77 and are projected onto a screen 111. The present invention is applicable to the image processing system.

  • Patent number: 7507457
    Abstract: An optical recording medium includes a support substrate, and a light transmission layer 12 that is disposed so as to come in contact with the support substrate. At least one of a refractive index of the support substrate and a refractive index of the light transmission layer, and an extinction coefficient of the support substrate and an extinction coefficient of the light transmission layer is different. As such, according to the invention, a reflective layer is not formed between the support substrate and the light transmission layer, such that the support substrate and the light transmission layer directly come in contact with each other. Accordingly, since at least one of the refractive index and the extinction coefficient is different, reflection occurs at the interface between the support substrate and the light transmission layer. Therefore, data held by a plurality of pits, that are arranged on the support substrate in a spiral shape or a concentric shape, can be correctly read out.

  • Patent number: 7470098
    Abstract: An optical sensor for detecting the housing state such as the thickness of a substrate in the present invention is provided at supporting arms. The supporting arms are attached to a supporting shaft. The supporting arms are in a vertical state in a state before detection of the substrate, but when detecting, the supporting shaft rotates to bring the supporting arms into a horizontal state so that the optical sensor enters a substrate housing body and is set at a predetermined detection position. Accordingly, a space for moving the optical sensor in the horizontal direction becomes unnecessary to reduce the space required for the detecting operation and the like, making it possible to reduce the size of a substrate processing apparatus in which the detecting apparatus is incorporated.

  • Patent number: 7304968
    Abstract: In an ad-hoc established device network, a profile based handover of the network control functionality is performed whenever a new device (15) requests association with the network and the central controller (16) does not support the profile of the new device (15). A database is searched for a controller-capable device that supports both the profiles of the network devices and the profile of the new device. The former central controller (16) passes the control functionality to the controller-capable device (17), which becomes the new central controller (24). Thus it is possible to associate the new device (15) with the network. The invention allows to integrate devices supporting different profiles into a common network.
