Various client devices include displays and one or more image capture devices configured to capture video data. Different users of an online system may authorize client devices to exchange information captured by their respective image capture devices. Additionally, a client device modifies captured video data based on users identified in the video data. For example, the client device changes parameters of the image capture device to more prominently display a user identified in the video data and may further change parameters of the image capture device based on gestures or movement of the user identified in the video data. The client device may apply multiple models to captured video data to modify the captured video data or subsequent capturing of video data by the image capture device.

A communication apparatus includes a wireless communication unit configured to wirelessly communicate with an external apparatus, a speaker, a memory, and a control unit, wherein in a case where an operation is executed to change the communication apparatus to a predetermined mode in which a sound is not output from the speaker, the control unit performs control such that the communication apparatus is changed to the predetermined mode, wherein in a case where identification information about the external apparatus is stored in the memory, the control unit enables a wireless communication function in response to the execution of the operation to change the communication apparatus to the predetermined mode, and wherein in a case where the identification information about the external apparatus is not stored in the memory, even if the operation to change the communication apparatus to the predetermined mode is executed, the wireless communication function is not enabled.

A communication apparatus includes a first communication unit for unencrypted communication compliant with a first standard for communication, and a second communication unit for encrypted communication compliant with a second standard for communication, In a case where connection information used for the second communication unit to perform encrypted communication with an external apparatus has been received from the external apparatus via the first communication unit, a control unit records the connection information on a recording medium. In a case where connection with the external apparatus has been established via the first communication unit, the control unit determines whether the connection information is currently recorded on the recording medium, and, in a case where it has been determined that the connection information is not currently recorded on the recording medium, the control unit causes a notification unit to issue a notification indicating that the connection information is not currently recorded.

The various embodiments described herein include methods, devices, and systems for providing event alerts. In one aspect, a method includes: (1) obtaining a first category for a first motion event, the first motion event corresponding to a first plurality of video frames; (2) sending a first alert indicative of the first category to a user; (3) after sending the first alert, obtaining a second category for a second motion event corresponding to a second plurality of video frames; (4) in accordance with a determination that the second category is the same as the first category, determining whether a predetermined amount of time has elapsed since the sending of the first alert; (5) if the predetermined amount of time has elapsed, sending a second alert indicative of the second category to the user; and (6) if the predetermined amount of time has not elapsed, forgoing sending the second alert.

A digital camera with a printer is a digital camera with a printer and includes a communication unit that communicates with a digital camera with a printer that is another apparatus, and an image composition unit that generates a composite image in which a first image captured by the digital camera with a printer that is an owned apparatus and a second image captured by the other apparatus are composited, in which the communication unit transmits the composite image to the other apparatus. A user of the other apparatus can also obtain the composite image. Accordingly, the composite image can be enjoyed by capturing images using a plurality of cameras.

An image pickup device includes first and second cameras, and first and second image signal processors (ISP). The first camera obtains a first image of an object. The second camera obtains a second image of the object. The first ISP performs a first auto focusing (AF), a first auto white balancing (AWB) and a first auto exposing (AE) for the first camera based on a first region-of-interest (ROI) in the first image, and obtains a first distance between the object and the first camera based on a result of the first AF. The second ISP calculates first disparity information associated with the first and second images based on the first distance, moves a second ROI in the second image based on the first disparity information, and performs a second AF, a second AWB and a second AE for the second camera based on the moved second ROI.

An electronic device comprises a determination unit configured to determine a target remaining-capacity of a battery provided in an accessory device connected to the electronic device, based on an operation mode of the electronic device; and a power supply unit configured to supply power to the accessory device based on the determined remaining-capacity.

A camera system according to the present disclosure includes a camera having a wireless communication function and configured to capture a video, and a signal processing device having a wireless communication function and configured to perform signal processing related to the video captured by the camera, and the camera and the signal processing device are wirelessly connected.

In a video system for imaging a target object by using first and second imaging devices, an information processing method is executed by the first imaging device. The information processing method includes: a step for acquiring a first elapsed time indicating the time elapsed after start of recording by the first imaging device; a step for requesting the second imaging device to transmit a second elapsed time indicating the time elapsed after start of recording by the second imaging device, and receiving the second elapsed time; a step for acquiring a required time to receive the second elapsed time after the request is made; and a step for, based on the first elapsed time, the second elapsed time, and the required time, calculating an offset time for synchronizing a first moving image recorded by the first imaging device and a second moving image recorded by the second imaging device.
