An image capturing apparatus capable of reducing a loss of a desired image capturing opportunity. The image capturing apparatus includes an image capturing unit that outputs image data, a memory device, and a processor. In a first operation mode in an pre-capturing mode, the processor displays the image data as a live view image on a display unit, holds pre-capture image data from detection of a first instruction instructing image capturing preparation to detection of a second instruction instructing recording of a captured image, and records main image data output in response to the second instruction and the held pre-capture image data in a recording medium when the second instruction is detected. In a second operation mode in the pre-capturing mode, the processor stops displaying the live view image, detects a change of an object based on the image data, and holds the image data based on a detection result.

Image capturing apparatus, control method therefor, and storage medium storing control program therefor

In an electronic device, a memory temporarily holds image data output from an image sensor during a first operation instruction instructing preparation for shooting is output, and an acquisition unit repeatedly acquires determination information used for estimating a level of possibility that a second operation instruction for instructing recording of a shot image will be output. A controller controls image shooting and to hold image data in the memory by a first control if the level is a first level, and by a second control that can reduce power consumption if the level is a second level which is lower than the first level. When the second operation instruction is output, the image data of an image shot in response to the second operation instruction and the latest image data held in the memory are recorded on a recording medium.

Electronic device and control method thereof

An image pickup apparatus to which an accessory is attachable includes a control unit communicable with the accessory, and configured to store information on power suppliable to the accessory and to acquire from the accessory at least one of information on the power required by the accessory, information on a power source for the accessory, and information on charge control of a battery provided in the accessory.

Image pickup apparatus, accessory, control method of image pickup apparatus, control method of accessory, and storage medium

An image pickup apparatus includes a first image sensor configured to perform imaging, and a control unit configured to perform precapture imaging, when acquiring a first imaging instruction, to cause the first image sensor to repeatedly perform imaging, and causes the first image sensor to perform main imaging when acquiring a second imaging instruction during the precapture imaging, and a first detecting unit configured to detect a change in a main object to be focused, and to output information about the change in the main object. The control unit changes control in the precapture imaging using the information about the change in the main object.

Image pickup apparatus

An electronic apparatus attachable to an accessory includes a power supply unit, and a control unit for controlling the power supply unit. The electronic apparatus can transition from a normal operating state to a power-saving state that includes a first power-saving state in which a power supply switch of the electronic apparatus is turned off, and a second power-saving state in which a non-operating state continues for a predetermined time. The control unit receives first information indicating whether or not the power supply from the electronic apparatus to the accessory is requested in the first power-saving state, and second information indicating whether or not the power supply from the electronic apparatus to the accessory is requested in the second power-saving state. The control unit causes the power supply unit to supply the power in the power-saving state where the power supply is requested.

Electronic apparatus and its control method, and accessory and its control method

A terminal apparatus capable of shifting to a power-saving mode with high accuracy in a case where a user puts the terminal apparatus in a bag or pocket A luminance distribution acquisition section acquires luminance distribution around the terminal apparatus. A storage area stores a learned model generated from time series information including the luminance distribution acquired by the luminance distribution acquisition section. A determination section determines, based on the time series information and the learned model, whether a user operation of the terminal apparatus has been terminated or in progress. A power supply section shifts the terminal apparatus to the power-saving mode according to a result of the determination performed by the determination section.

Terminal apparatus having power-saving mode, method of controlling same, and storage medium

An imaging apparatus on which an accessory is mountable includes a control unit configured to control first communication with the accessory via a first communication unit and second communication with the accessory via a second communication unit, and, in a case where a communication error in the second communication is detected, perform communication retry processing that repeats transmission of data up to a predetermined number of times until the communication error is resolved. In the case where the communication error in the second communication is detected, the control unit issues a notification corresponding to the communication error to a user without performing the communication retry processing in a case where information corresponding to the fact that the accessory does not receive the data via the second communication is received via the first communication.

Imaging apparatus and method for controlling the same

An electronic device comprises: a motion detector configured to detect motion of the electronic device; a proximity detector configured to detect proximity of an object to the electronic device; a display unit; a memory; and at least one processor that function as: a control unit configured to control display preparatory processing for performing display on the display unit so as to start in response to predetermined motion of the electronic device being detected based on motion detected by the motion detector; and a display control unit configured to control display so as to be performed on the display unit in response to proximity of an object being detected by the proximity detector.

Electronic device for detecting object proximity and controlling a display

Display is appropriately switched between an EVF display and a rear display of a camera based on proximity detection. A proximity detection unit detects proximity of a user viewing through the EVF. An orientation detection unit detects an orientation of the camera main body. If the proximity detection unit detects proximity within a predetermined threshold, a system control unit switches display to display of the EVF. If the orientation detection unit detects a predetermined motion, the system control unit changes a threshold of the proximity detection to a value indicating a distance far from the EVF.

Electronic apparatus, method for controlling the same, and storage medium

An image capturing apparatus has an image sensor in which unit pixels each having a plurality of photoelectric conversion portions are arranged in matrix, a readout unit for performing a first readout operation of reading out signals of a portion of the plurality of photoelectric conversion portions and a second readout operation of reading out signals of a greater number of the plurality of photoelectric conversion portions, a switching regulator, and a frequency controller for controlling a switching frequency of the switching regulator. The frequency controller controls the switching frequency such that the phase of the switching frequency satisfies predetermined relationship, with respect to a timing for reading out noise signals, a timing for reading out signals by the first readout operation, and a timing for reading out signals by the second readout operation.
