  • Patent number: 8208057
    Abstract: An imaging system includes an interchangeable lens and a camera body. The camera body includes a main body controller operable to transmit a reference signal for providing a reference of a driving start timing of the focus lens and delay time information indicating delay time with respect to the reference signal, to the interchangeable lens. The interchangeable lens includes a lens controller operable to control the focus lens to be driven at a timing obtained by delaying the timing provided by the reference signal by the delay time based on the reference signal and the delay time information received from the main body controller. The delay time is set so that, for example, an exposure timing of a predetermined area in the imaging element is substantially coincident with a stop period of the wobbling operation of the focus lens.

  • Patent number: 8203628
    Abstract: A camera system that can maintain a good focus state regardless of the speed of zooming during variable proportion zooming is provided. The camera system has a control portion that, based on information on the speed of the change in the focal length, determines whether to control a focus lens drive portion in either a first control mode or a second control mode. If it determines that control is to be performed in the first control mode, then the control portion controls the focus lens drive portion so that it drives a focus lens in the direction that brings a predetermined captured object into focus based on estimated values for auto focusing that have been calculated from the image data at various positions by controlling the focus lens drive portion so that the captured object distance is moved forward and backward in the optical axis direction.

  • Patent number: 8194180
    Abstract: An imaging apparatus includes an optical system including a focus lens, a driver configured to drive the focus lens, a controller configured to control a supply of power to the driver, and a setting unit configured to set a power supply mode for specifying a method of supplying power to the driver. When a predetermined power supply mode is set, the controller determines according to a magnitude of a depth of field of the optical system during whether holding power for holding the state of the focus lens is supplied to the driver when the focus lens is stopped, and controls the supply of the holding power to the driver according to the result of the determination.

  • Patent number: 8194336
    Abstract: A lens driving device has a carrier, a coil, an upper spring, a lower spring, a yoke, a magnet, and a lower member. The carrier is cylindrical and has a hollow part along a vertical direction so that a lens can be carried. The coil is fixed to an outer peripheral surface of the carrier. The upper spring is arranged over the carrier, and fixed to the yoke. The lower spring is arranged below the carrier. The yoke is formed into a box shape having a side wall and an opening on the lower side, and arranged around the carrier. The magnet is arranged in the yoke so as to be opposed to the coil. The lower member is arranged below the yoke. The lower member has a projection part connected to the yoke. The projection part is inserted between an inner surface of the side wall of the yoke and an outer surface of the magnet and connected to the yoke. Thus, the yoke and the lower member can be connected such that space for the magnet to be arranged in the yoke is less affected.

  • Patent number: 8185756
    Abstract: An electronic device capable of controlling a power state of an external device from a first power state (ex. “Standby”) to a second power state (ex. “ON”) includes a determination unit operable to determine whether information indicating linkage is stored in a storage unit when it is detected that communication between the electronic device and the external device is enabled, and a transmitting unit operable to transmit a control signal for controlling power state of the external device. When the information indicating linkage is not stored in the storage unit, the transmitting unit stores the information indicating linkage and transmits the control signal for controlling power state of the external device to the second power state to the external device. When the information indicating linkage is stored in the storage unit, the transmitting unit refrains from transmitting the control signal to the external device.

  • Patent number: 8178955
    Abstract: A semiconductor device includes: a semiconductor element; a die pad with the semiconductor element mounted thereon; a plurality of electrode terminals each having a connecting portion electrically connected with the semiconductor element; and a sealing resin for sealing the semiconductor element, the die pad and the electrode terminals so that a surface of each electrode terminal on an opposite side from a surface having the connecting portion is exposed as an external terminal surface. A recess having a planar shape of a circle is formed on the surface of each electrode terminal with the connecting portion, and the recess is arranged between an end portion of the electrode terminal exposed from an outer edge side face of the sealing resin and the connecting portion.
