  • Publication number: 20150138222
    Abstract: An image processing device, for making a plurality of projectors project an image based on an input image signal such that a part of a projection region overlaps, includes an acquiring unit and a generating unit. The acquiring unit acquires distribution information on distribution of a luminance of a displayed image when the projector projects the image based on an image signal in which a pixel value is constant. The generating unit generates an image signal for each projection of the plurality of projectors, by correcting the input image signal by using each distribution information of the plurality of projectors.

  • Patent number: 7586518
    Abstract: A focusing technique detects motion vectors of a plurality of images, combines the images in accordance with the detected motion vectors, extracts a signal corresponding to a focusing state of a lens unit with respect to a subject, and controls the lens unit in accordance with the extracted signal to perform focusing.

  • Patent number: 7052551
    Abstract: To provide a method of manufacturing a battery capable of providing an equal amount of electrolyte in each battery and of enhancing productivity and coating machines employed thereof. The sensor detects a boundary from the collector exposed region C of the belt-shaped positive electrode to the positive electrode mixture layer exposed region B, on the basis of the detection timing, the shutter is withdrawn to open the flowing path and the proportioning pomp is driven. Following this, when the sensor detected a boundary from the positive electrode mixture layer exposed region B to a collector exposed region C, and on the basis of the detection timing, the shutter is protruded inside the flowing path to close the flowing path and the proportioning pump stops. As a result of this, the electrolyte stops to be delivered from the nozzle. The electrolyte layers are intermittently formed by repeating the same procedures.

  • Patent number: 6963373
    Abstract: An image processing apparatus which eliminates noise which occurs due to the influence of output from a parallel bus drive circuit added to an output final stage circuit of signal processor or the like. A delay circuit 110 which delays a video signal is inserted into a VTR signal processor such that a data transition point of particular bit in a bit array indicating horizontal-directional start and end positions of video signal data, added during a horizontal retrace period of a digital recording format video signal, does not overlap with a period for sampling a feedthrough period and a photoelectric conversion signal period in a correlated double sampling circuit.

  • Patent number: 6632256
    Abstract: The surface of a positive-electrode active material layer or a negative-electrode an active material layer is coated with a gel electrolyte composition to form a gel electrolyte layer. The positive and negative electrodes are laminated such that the gel electrolyte layer is sandwiched. At this time, the gel electrolyte composition is formed into a sol form so as to be applied to the surface of the positive-electrode active material layer or the negative-electrode active material layer. The viscosity of the gel electrolyte composition formed into the sol form is 1 cp to 50 cp. The gel electrolyte composition is formed into the sol form by heating the gel electrolyte composition or diluting the gel electrolyte composition with nonaqueous solvent. When dilution with the nonaqueous solvent is performed, solvent having a high boiling point and solvent having a low boiling point are mixed with each other.
