A reception unit receives an eye direction input that is an input based on an eye tracking process, and a control unit controls movement of a selected position based on an operation on an operation member. The control unit performs control such that, in a first state in which the selected position is not designated based on the eye direction input, the selected position is moved, in response to the operation member being operated by a predetermined operation amount, by a first amount from a position set before the operation member is operated, and that, in a second state in which the selected position is designated based on the eye direction input, the selected position is moved, in response to the operation member being operated by the predetermined operation amount, by a second amount smaller than the first amount from a position based on the eye direction input.

An image capturing apparatus that includes a mounting part capable of attaching/detaching a device capable of holding at least an image captured by the image capturing apparatus and capable of communicating with the mounted device in accordance with a predetermined standard is provided. The apparatus outputs to a device, if the device having a function of executing image analysis processing for image data captured by the image capturing apparatus is mounted in the mounting part, a command complying with the predetermined standard and configured to cause the device to execute the image analysis processing. The apparatus outputs at least two commands associated with each other and configured to cause the device to execute the image analysis processing, wherein each of the at least two commands includes data representing that the at least two commands are associated with each other.

A mobile terminal, a shooting mode detection method, and a storage medium are provided. The mobile terminal includes a terminal body which has a placement portion for placing a camera module. The mobile terminal further includes the camera module detachably connected to the terminal body. The mobile terminal also includes a first Hall sensor and a second Hall sensor. The first Hall sensor and the second Hall sensor are respectively electrically connected to a processor built in the terminal body and fixedly arranged on a side on which the placement portion of the terminal body is located. The mobile terminal additionally includes a magnetic structural element which is fixed on an end of the camera module close to the placement portion. When the camera module is placed on the placement portion, the magnetic structural element is opposite to the first Hall sensor or the second Hall sensor.

Provided are a device and a method by which high-precision auto focus (AF) processing can be performed while a focus lens or a zoom lens is being operated. An interchangeable lens acquires position information regarding a focus lens and a zoom lens at a predetermined time interval during an exposure time period of detection information acquisition pixels for use in calculation of a defocus amount (DF), and outputs the position information to an imaging device. The imaging device calculates the defocus amount (DF) by using information regarding the detection information acquisition pixels, calculates a reference focus lens position (Ref_fc) by using points, on a cam curve, corresponding to the inputted lens position information, calculates a target focus lens position (Tgt_fc) in an in-focus position, from the reference focus lens position (Ref_fc) and the defocus amount (DF), and outputs the target focus lens position (Tgt_fc) to the interchangeable lens.

An accessory includes: a detection terminal; a first power supply terminal through which a first power supply voltage is supplied; a first ground terminal used as a ground potential; a second power supply terminal through which a second power supply voltage is supplied; a second ground terminal used as a ground potential; a ready terminal used to indicate whether or not communication is allowed: a first data terminal that receives a first data signal; a second data terminal that outputs a second data signal; a clock terminal that outputs a clock signal; and a third data terminal that outputs a third data signal, wherein: the first ground terminal, the second power supply terminal, and the second ground terminal are positioned between the first power supply terminal and the ready terminal; and the first data terminal and the second data terminal are positioned between the ready terminal and the clock terminal.

An accessory detachably attached between an interchangeable lens and an imaging apparatus includes a communication unit for communicating with the interchangeable lens and the imaging apparatus, a first operation unit operated when focus position information on the interchangeable lens is to be acquired from the interchangeable lens, a memory unit storing information relating to focus of the interchangeable lens based on the focus position information, a second operation unit operated when reproduction driving is to be performed of a focus lens included in the interchangeable lens, and a control unit controlling driving of the focus lens. When the first operation unit is operated, the control unit acquires the information relating to focus by using the focus position information. When the second operation unit is operated, the control unit performs the reproduction driving of the focus lens by using the information relating to focus.

A body part of a camera includes a display that is at least partially flexible. A display part of the display includes a first display part and a second display part that are integrally formed. A hinge part that connects the first display part to the second display part to be rotatable relative to each other is provided in the vicinity of a bendable part located at a boundary of each display part. The display is bendable in accordance with rotation of the hinge part with the bendable part as a starting point.
