  • Patent number: 8248512
    Abstract: The present invention provides full-parallax images having high spatial resolution in real time. An image-capturing optical unit (21) includes a plurality of prismatic mirrors (41) which rotate at a predetermined period. The side surface of each of the prismatic mirrors (41) reflects a light beam from an object. A camera receives the light beam from the object reflected by the prismatic mirrors (41) in order to capture an image of the object. On the other hand, a display optical unit (32) includes a plurality of prismatic mirrors (51) which rotate in phase with the prismatic mirrors (41) at the same period. A projector emits a light beam corresponding to the image of the object captured by the camera, and such a light beam is reflected by the prismatic mirrors (51). A user may view an image corresponding to the light beam reflected by the prismatic mirrors (51).

  • Patent number: 8242973
    Abstract: An image processing apparatus receives first and second input image signals and generates first and second projection image signals for projecting images from first and second projectors so as to be superimposed on a screen. A storage unit stores, for each projection position on the screen, intensity ratios between projected light from the first and second projectors when viewing from first and second viewing position. An intensity correcting unit adds the first and second input image signals in proportions set for generating the first projection image signal and in proportions set for generating the second projection image signal, according to the stored intensity ratios. The first projection image signal is supplied to the first projector and the second projection image signal is supplied to the second projector.

  • Patent number: 8235387
    Abstract: An image forming apparatus includes: a plurality of trays; a plurality of full-stack detectors; a first storage section; a second storage section; and a controller. The plurality of trays are loaded with first sheets that are output from an image forming section. Each of the plurality of full-stack detectors is provided at one of the plurality of trays, each full-stack detector detecting that a corresponding tray is full of first sheets. The first storage section stores the number of second sheets printed in the past by sheet type. The second storage section stores usage priorities of the trays by sheet type based on the contents stored in the first storage section and a sheet stack capacity of each tray. The controller decides a first tray for outputting a third sheet that is output this time based on the priorities stored in the second storage section.

  • Patent number: 8228568
    Abstract: The document read apparatus according to the present invention has a light source unit that includes a linear first light and second light sources, both light sources aligned parallel to the sub scanning direction (moving direction). When the light source unit is scanning a book document in a second region shifted toward a side of the first light source from a center position for emitting light to the center of the document, a light quantity of the second light source becomes larger than a light quantity of the first light source. When the light source unit is scanning the book document in a third region shifted toward a side of the second light source from the center position, the light quantity of the first light source becomes larger than the light quantity of the second light source. A sum of both light quantities is controlled to be constant.

  • Publication number: 20120140021
    Abstract: In a communication system, a communication terminal displays an image based on display data being displayed and sent by an external apparatus. The communication terminal sends first resolution data specifying a resolution of a display of the communication terminal to the external apparatus. The external apparatus determines a resolution of the display data to be transmitted, based on the first resolution data, and second resolution data specifying a resolution of a display of the external input apparatus. The external apparatus sends the display data, which is converted to have the determined resolution, to the communication terminal.

  • Patent number: 8190049
    Abstract: An image forming apparatus performs a single-side image formation such that, when a delay is needed, a stacked sheet discharge control section controls a sheet carrying mechanism so that: a first sheet (for a second imaging job) to be discharged after passing a first sheet-discharging roller via a first sheet-carrying path is directed to another carrying path without being discharged, and is stood by therein. The first sheet and a second sheet (for the second imaging job) which is carried to the first sheet-discharging roller via the first sheet-carrying path after the first sheet, then are concurrently discharged overlappingly. This eliminates needs for delaying image formation for the second imaging job, and for securing time for post-process for the first imaging job. Even if a delay is inevitable, this reduces the delay time greatly and improves the productivity of the image forming apparatus, without reducing its performance wastefully.

  • Publication number: 20120115030
    Abstract: An electricity-storing device electrode comprises a current collector foil, an active material layer formed on a surface of the current collector foil, and a high-resistance layer formed on the surface of the current collector foil so as to be adjacent to and in direct contact with the active material layer. At least a portion of the interface between the active material layer and the high-resistance layer, mixed phase is formed where constituents from the two layers intermingle. Presence of the mixed phase at the interface between the active material layer and the high-resistance layer improves the bond between the two adjacent layers. During manufacture and use, there is therefore reduced tendency to experience delamination or loss of the active material layer, the high-resistance layer, and/or other layer(s), such as layer(s) provided for short circuit prevention.
