  • Patent number: 7952732
    Abstract: A digital multi-function peripheral appends, according to the predetermined specific image information appending conditions, the image data which meets the appending conditions with the specific image information in a form which is set in accordance with the appending conditions when image data which is read at an image reading portion or image data which is externally entered via a FAX modem or communication portion is used for image formation at a printing portion. It is set so that the specific image information is appended to high secrecy image data. When trying to copy the printed image in which the specific image information is embedded, the copy machine which has detected the specific image information will not output the copied image or output a copy sheet having thereon characters such as “Copy Prohibited”.

  • Patent number: 7952977
    Abstract: A diffracting portion is disposed in an optical path between a light source and an optical disc. The diffracting portion diffracts the reflected light from recording layers of the optical disc toward a light receiving portion. The diffracting portion includes a first diffraction region having a first diffraction efficiency and a second diffraction region having a second diffraction efficiency lower than the first diffraction efficiency. The first diffraction region includes a FES diffracting portion and first to fourth TES diffracting portions. The second diffraction region includes fifth and sixth TES diffracting portions. First-order diffraction lights from the non-light-collecting recording layer enter on the fifth and the sixth TES diffracting portions, and are diffracted toward the light receiving portion by the fifth and the sixth TES diffracting portions.

  • Publication number: 20110122054
    Abstract: An OCB-mode liquid crystal display device includes an accumulation capacitance bus line (13) arranged on a TFT substrate (20) so as to sandwich an insulation film (14) and superposed on a pixel electrode (11). The pixel electrode (11) has an opening (15) in a part of the region where the pixel electrode (11) and the accumulation capacitance bus line (13) are superposed via the insulation film (14). By causing a potential difference between the pixel electrode (11) and the accumulation capacitance bus line (13), a lateral electric field is generated in the vicinity of the opening (15) to form a nucleus for transition from the twist orientation to the spray orientation. When the power is turned off to stop display, it is possible to rapidly perform orientation transition from the twist orientation to the spray orientation.

  • Publication number: 20110122466
    Abstract: Image data Rin, Gin, Bin are read out from an image on a document, on reception of light reflected by the image after being emitted from a first light source for irradiating the document with visible light. Image data RUV, GUV, BUV are read out from the image on the document, on reception of light reflected by the image after being emitted from a second light source for irradiating the document with ultraviolet light. A color correction process is performed by reading out color corrected imaged data from a color correction table which stores in advance color corrected image data, which are associated with a combination of (i) image data, which correspond to the image data Rin, Gin, Bin, and image data which correspond to the image data RUV, GUV, BUV. By this, it is possible that even in a case where an image on the document contains a fluorescent image, the fluorescent image be easily and accurately reproduced.

  • Publication number: 20110123184
    Abstract: A camera flash comprises a light guide arranged to extract light at least through one surface; and one or more light sources arranged, in use, to emit light into the lightguide. Each light source is an LED or a laser diode. The camera flash is connectable, in use, to drive circuitry, the drive circuitry being for driving the light source(s) to emit a pulse of light. The waveguide spreads out the light from the light source(s), so that a flash of light from the camera flash does not present a safety risk, while minimising loss of the light from the light source(s). The camera flash can thus provide a high overall optical output, spread over an extended area (as defined by the waveguide). The lightguide may for example be disposed around a camera module of a mobile telephone camera.
