An information processing apparatus includes a communication unit configured to communicate with a camera configured to capture a third image which is one image in which left and right images are arranged, and a control unit configured to display the third image on a display unit and set a position of an enlarged range to which enlargement processing is to be applied by the camera in the third image displayed on the display unit, and the control unit converts the set position of the enlarged range based on a display format in which the third image is displayed on the display unit, and outputs an instruction to the camera.

A medical image acquisition system includes an imaging device and an image processing device. The imaging device includes: an imaging unit configured to receive light and convert the light into an electric signal so as to generate the imaging signal; an optical unit including a focus mechanism moving one or a plurality of lenses so as to adjust a focal point position, and configured to form an optical image on the imaging unit; a memory configured to store therein unique information of the imaging device; and an auto focus controller configured to totally control the imaging device. The image processing device includes an auto focus evaluation unit configured to perform focusing evaluation based on the imaging signal, and the auto focus controller controls driving of the focus mechanism by referring to the unique information in accordance with an evaluation result by the auto focus evaluation unit.

An imaging apparatus includes an interchangeable lens, and a camera body. The interchangeable lens includes a correction lens, a lens driver, and a first controller. The camera body includes an image sensor, a sensor driver, and a second controller. The first or second controller selects one of the interchangeable lens and the camera body, in accordance with a level of correction capability to perform the image stabilization. Corresponding to the selected one, one driver of the lens driver and the sensor driver performs the image stabilization for the image blur within a predetermined range. The other driver corresponding to non-selected one performs the image stabilization for a remaining portion of the image blur exceeding the predetermined range.

A remote control unit for controlling a motion picture camera comprises a grip section at a first side for holding the remote control unit, an extension section at a second side and a display section extending from the grip section to the second side. The display section comprises a display at a front side thereof, which is oriented orthogonal to a viewing axis. The extension section projects away from the display section. The extension section comprises an operating side facing away from the grip section, at which side a rotatable operating element for setting control commands is arranged.

An apparatus that is capable of displaying a good live view image even during continuous emission photographing. The apparatus includes a sensor, a memory device that stores a set of instructions, and at least one processor that executes the set of instructions to obtain a display image cyclically using the sensor, and obtain a flash control image accompanied with a pre-emission of a first flash unit using the sensor at a non-accumulation timing at which the sensor does not perform charge accumulation for cyclic obtainment of the display image.

An image capturing apparatus communicates with a strobe device used for image capturing and acquires preliminary light emission result information performed by the strobe device. A light control process for determining a light amount of main emission by the strobe device for main image capturing is executed based on the acquired preliminary light emission result information. In a case where an image capturing frequency for repeating image capturing is higher than a threshold value, information which is different from information on the light amount of main emission and is used for settings of preliminary light emission or main light emission is communicated by dividing the information into information acquired by a first communication processing before preliminary light emission and information communicated by a second communication processing after preliminary light emission.

A lens control apparatus includes an operation input unit, a communication unit, and a control unit. The operation input unit is configured to accept a user operation. The communication unit is configured to perform communication with an external apparatus. The control unit is configured to perform driving control of a zoom lens in response to a zoom operation accepted by the operation input unit or a zoom control signal received by the communication unit. The control unit is also configured to selectively set a zoom position changing speed for driving control performed in response to the zoom operation and a zoom position changing speed for driving control performed in response to the zoom control signal, the zoom position changing speeds being different from each other.

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 image capturing apparatus includes an area sensor on which photoelectric conversion elements are arranged two-dimensionally, and that includes a plurality of regions, a reading unit for reading, from the area sensor, signals photoelectrically converted by the photoelectric conversion elements, a focus detection unit for performing focus detection using the signals read by the reading unit, and a control unit for performing control as to from which region of the plurality of regions the reading unit preferentially reads the signals of the photoelectric conversion elements.

A camera body includes a plurality of electric contacts in a first set and a second set. When a lens apparatus is mounted to the camera body, the first set of the electric contacts comes into contact with an electric contact disposed on the lens apparatus before coming into contact with the second set of electric contacts.
