An apparatus includes an optical member, a detector configured to detect a quantity relating to a position of the optical member, and a processor configured to generate positional information of the optical member based on the quantity relating to the position. The processor is configured to generate timing information of the detection corresponding to the positional information.

Apparatus, system, method and computer readable storage medium for generating positional information of optical member and timing information relating thereto

A control apparatus is configured to control a driver configured to drive a driven member, which driver is provided in an optical apparatus that is attachable to and detachable from an image pickup apparatus. The control apparatus includes an information acquirer configured to acquire information on a suppliable power from the image pickup apparatus to the optical apparatus, and a changer configured to change a control method of the driver according to the information.

Image pickup apparatus, optical apparatus, control apparatus of the optical apparatus, control method, and medium, for controlling driving mode of a driver based on supply power level or driving state thereof

In a camera body, a VBAT terminal and PGND terminal are both disposed adjacent to a TYPE terminal. In a case where the voltage of the TYPE terminal is a voltage of a first voltage range that does not include the VBAT voltage and does not include the voltage of the PGND terminal, a camera control unit distinguishes the mounted lens apparatus to be a first lens apparatus. In a case where the voltage of the TYPE terminal is a voltage of a second voltage range that is a voltage range different from the first voltage range, does not include the VBAT voltage and does not include the voltage of the PGND terminal, the camera control unit distinguishes the mounted lens apparatus to be a second lens apparatus.

Lens apparatus, imaging apparatus, and intermediate accessory

There is provided an image capturing apparatus on which, and from which, an accessory is mountable and dismountable by relative rotation in a circumferential direction. The image capturing apparatus includes a plurality of terminals disposed in a circumferential direction of a mount and configured to be used in electrical connection, and a terminal holder. Each of the plurality of terminals is electrically connected to a corresponding terminal of the accessory. A first terminal of the terminals used in communication at a first voltage level and a second terminal of the terminals used in communication at a second voltage level lower than the first voltage level are disposed on the same stage of the terminal holder. The second terminal is a terminal connected to ground via a first resistor. The first terminal is disposed adjacent to the second terminal.

Image capturing apparatus and accessories

A mechanism in a wire electrical discharge machining apparatus for machining a workpiece by electrical discharge between a wire and the workpiece is disclosed. The mechanism includes a processing fluid bath configured to store processing fluid used for electrical discharge machining between the workpiece and the wire, a processing fluid supply port to communicate with the processing fluid bath and supply the processing fluid into the processing fluid bath from a processing fluid supply apparatus supplying the processing fluid, and a stream control mechanism to suppress a stream of the processing fluid supplied from the processing fluid supply port into the processing fluid bath in the direction of the water surface of the processing fluid in the processing fluid bath.

Wire electrical discharge machining apparatus, wire electrical discharge machining method, and work

An apparatus and a method of controlling the apparatus are provided that can realize high-accuracy correction of image shake due to shift shake. Rotation radiuses at a plurality of frequencies among the frequency components of the shift shake are obtained. Correction amount is determined based on a result of assigning a respective weight to the rotation radius at each of the plurality of the frequencies based on information regarding at least one of an angular velocity and acceleration.
