[Object] To provide a signal transmission device and management system which are capable of transmitting a signal including information of an attachment target or information of the surrounding of an attachment target. [Solution] A management system includes: a signal transmission device which includes a housing that is attached to an object to be managed in a predetermined direction, a first optical power generation unit and a second optical power generation unit that have light receiving units on a first surface and a second surface facing outwardly in a predetermined direction, respectively, a first temperature sensor and a second temperature sensor that have thermal contacts on the first surface and the second surface, respectively, a communication control unit for transmitting a signal including temperature information detected by the first temperature sensor and the second temperature sensor using power generated by at least one of the first optical power generation unit and the second optical power generation unit; and an information processing device which has a control unit for receiving a signal transmitted from the signal transmission device and outputting the state information of an object to be managed to which the signal transmission device is attached on the basis of the temperature information detected by at least the first temperature sensor and the second temperature sensor.

Signal transmission device and management system

The present technology relates to a power controller, a power control method, and a program which appropriately supply power to an actuator for driving a shutter and an actuator for camera shake correction. A power controller includes a shutter controller for controlling a shutter driving unit, a camera shake correction controller for controlling a camera shake correction driving unit, and a power amount setting unit for setting amounts of power to be allocated to the shutter driving unit and the camera shake correction driving unit according to a set shutter speed. The power amount setting unit allocates the amount of power to be supplied to the camera shake correction driving unit when the shutter speed is equal to or less than a predetermined speed to the shutter driving unit in a case where the shutter speed is faster than a predetermined speed. The present technology available for an image pickup device.

Power controller and power control method

Lens mount

An imaging system includes an imaging apparatus which is provided with an imaging device and a mount adaptor which adjusts a flange focal length between the imaging apparatus and an interchangeable lens, wherein the mount adaptor is provided with a phase difference focus detection section which performs focus detection from a phase difference and an optical device which splits incident light from the interchangeable lens into incident light of the imaging device and incident light of the phase difference focus detection section, and the imaging apparatus is provided with a contrast focus detection section which performs focus detection from contrast using the imaging device, an adjustment section which adjusts the focus position of the phase difference focus detection section, and an adjustment control section which activates adjustment control of the focus position using detection of the mounting of the mount adaptor and the interchangeable lens.

Imaging system, mount adaptor, imaging apparatus, and program

A mount adapter includes: a camera cone having a length of adjusting a flange focal length between an imaging device provided with an imaging element and an interchangeable lens; a focus detection unit carrying out focus detection from a phase difference; an optical device separating an incident light from the interchangeable lens into an incident light of the imaging element and an incident light of the focus detection unit; and a correction information storage unit storing correction information used for correction of an error between the flange focal length and a distance from a mounting surface of the interchangeable lens to the focus detection unit.

Mount adapter and imaging device

An image pickup apparatus including a half mirror, a phase difference detecting AF sensor, an image pickup device, and a display is provided. The half mirror is provided so as to be movable between a first position on an optical path of the subject image light from the photographing optical system and a second position to which the half mirror is evacuated from the optical path of the subject image light. When the half mirror is in the second position, the image pickup device generates an actual photographing image on the basis of the subject image light reaching the image pickup device from the photographing optical system without passing through the half mirror.

Mount

In an imaging apparatus with a shake correction function, the influence of front curtain shock is prevented from being exerted on a shake correction function section (shake correction drive). The imaging apparatus includes a shake detection sensorthat detects an amount of shake applied to a digital camera, a shake correction unitthat performs a shake correction drive of an imaging deviceon the basis of a shake amount detection signal, a shutter unitthat is arranged immediately in front of the imaging deviceand performs an optical-path opening operation and an optical-path blocking operation for opening and blocking an optical path of light guided to the imaging device, a timing control circuitthat supplies a predetermined reset signal to each pixel for each predetermined pixel line so as to start exposure on the imaging device, and a shutter control sectionthat controls exposure of the imaging device. At the time of shooting, the shutter control sectionexecutes an electronic shutter control (electronic focal plane shutter) for starting exposure on the imaging deviceby means of the reset signal supplied to each pixel from the timing control circuit

Imaging apparatus with shake correction

An image pickup apparatus includes a controlling unit moving an electronic front curtain in a simulated manner from an exposure start position towards an exposure end position by successively performing reset operations on a plurality of pixels in an image pickup element in a predetermined direction; a rear curtain that moves from the exposure start position towards the exposure end position by a biasing force of a biasing unit; and a storage unit storing data indicating a change in movement characteristics of the rear curtain with time. On the basis of the data, the controlling unit changes movement characteristics of the electronic front curtain in accordance with the change in the movement characteristics of the rear curtain with the time.

Image pickup apparatus shutter control

An image pickup apparatus includes: a shutter device; an image pickup element adapted to sequentially acquire time-series images regarding object images passing through an exposure opening of the shutter device; and control section configured to control operation of the shutter device and operation of the image pickup element.

Image pickup apparatus

An imaging apparatus includes a first imaging sensor, a second imaging sensor, a display unit, an electronic viewfinder unit, a position changing unit and a sensor-shift shaking correction unit. The first imaging sensor acquires an image relating to a subject at the time of main photography. The second imaging sensor acquires an image relating to the subject before the time of main photography. The sensor-shift shaking correction unit performs shaking correction at the time of the main photography, by changing a position of the first sensor with the position changing unit. The electronic viewfinder unit performs consecutive image display on a display screen of the display unit, based on images sequentially acquired by the second imaging sensor before the main photography, and includes an electronic shaking correction unit that performs shaking correction of the consecutive image display, by changing the display position of the images on the display screen.

Imaging apparatus including shaking correction for a second imaging sensor

Disclosed herein is an image pickup apparatus including: an image sensor; and a shutter device, wherein said shutter device includes a trailing curtain, a first driving member, a second driving member, first urging force applying means, and a charging member.
