  • Publication number: 20070147814
    Abstract: An image capturing apparatus includes: a shake amount detecting unit that detects a shake amount; a composition determining unit that determines whether the composition of a picture is determined during image capturing on the basis of the correlation among a plurality of frames; a shake correcting unit that performs a shake correcting process on a captured image on the basis of the detected camera shake amount; and a correction control unit that controls the shake correcting unit to start the shake correcting process when the shake amount is smaller than a predetermined reference shake amount and it is determined that the composition of a picture is determined.

  • Publication number: 20070122129
    Abstract: An image pickup device is provided which includes: an auto focus control unit sampling contrast values as a function of a relative distance from an object by detecting a contrast of an image of the object while driving a lens in an optical axis direction, calculating a focused focal position on the basis of the contrast values, and driving the lens to the focused focal position; a shake detecting unit detecting at least an amount of shake in the optical axis direction of the lens; and a selection judging unit judging selection and non-selection of the sampled contrast values depending on the amount of shake in the optical axis direction of the lens at the time of the sampling. Here, the auto focus control unit calculates the focused focal position on the basis of the contrast value judged as being selected by the selection judging unit among the sampled contrast values.

  • Patent number: 6471641
    Abstract: In joining an angle section with an elongated flexible body of an endoscopic insertion instrument, a connector ring on the side of the angle section and a connector ring on the side of the flexible body are connected by fitting engagement, one connector ring on the outer side of the other connector ring. A number of inwardly projecting ridges are provided on the inner periphery of the inner connector ring, and screw holes are bored radially through the inwardly projecting ridges. On the other hand, a number of perforations are provided in the outer connector ring at positions corresponding to the screw holes in the inner connector ring. Screw members are threaded into the respective screw holes of the inner connector ring through the perforations in the outer connector ring. Further, a screw anchor ring is slidably fitted on the outer connector ring.

  • Patent number: 6188425
    Abstract: An optical shutter drive period detector detects a drive period of each optical shutter element. Based on the detected drive period, an optical shutter drive voltage control device sets an optical shutter driving voltage which is applied to an optical shutter driver. Furthermore, an optical shutter open period controller sets an optical shutter open period corresponding to the set optical shutter driving voltage and to a tone level of a pixel to be exposed and the optical shutter open period is input to the optical shutter driver as data for changing an optical shutter open period. Based on the optical shutter driving voltage and the optical shutter open period changing data, the optical shutter driver drives each optical shutter element of an optical shutter array, an electrostatic latent image is formed on a surface of a photosensitive drum, and the electrostatic latent image is developed by a developer, transferred by a transfer/separation charger onto a recording sheet and discharged.

  • Patent number: 6014540
    Abstract: An image forming apparatus includes a movable recording medium bearing member, an image forming device for forming an image on the image bearing member with a developer having an additive and a cleaning device having a cleaning member which makes a contact with the image bearing member for cleaning thereof at a cleaning station. The apparatus further includes a transferring device for transferring the image from the image bearing member to a recording medium. A processing device is mounted between the transfer station and the cleaning station for processing the additive that has not been transferred but still remains on the image bearing member such that one component of the additive remains on the image bearing member and another component of the additive is removed.

  • Patent number: 5557381
    Abstract: A developer supplying container of cylindrical shape which is connectable in a direction of its rotational axis. The container having a developer sending aperture on a base, a developer receiving aperture on the opposite base, and a connecting member to detachably connect the container to a second container having the same construction as the former container. The developer accommodated in the former container is transported to the second container through the developer sending aperture of the former container and a developer receiving aperture of the second container, and supplied to the developing device with the developer accommodated in the second container. When the developer accommodated in the former container is exhausted, only the former container should be replaced.

  • Patent number: 5395037
    Abstract: A method for bonding a solder wire is provided wherein a lower ball end of a material solder wire is first bonded to a first bonding portion of a workpiece. Then, the material solder wire is thermally cut to provide a solder wire segment held bonded to the first bonding portion and having an upper ball end. Finally, the upper ball end is bonded to a second bonding portion of the workpiece. All of the wire bonding process steps are performed in an oxygen-free atmosphere to prevent oxidation of the solder wire.
