An image capture apparatus acquires exposure delay times and communication delay times of respective other image capture apparatuses, the exposure delay times being information of times from when the other image capture apparatuses receive a shooting command until when the other image capture apparatuses start exposure, the communication delay times being information of times required in communication with the other image capture apparatuses, and determines a common delay time based on the acquired communication delay times and exposure delay times of the respective other image capture apparatuses, the common delay time being delay time information that is common to all of the other image capture apparatuses, and upon accepting a shooting instruction, transmits the shooting command including a common timing obtained from the common delay time to the other image capture apparatuses.

A dual-aperture camera comprising a first camera having a first sensor and a first image signal processor (ISP), the first camera operative to output a first stream of frames, a second camera having a second sensor and a second ISP, the second camera operative to output a second stream of frames, and a synchronization and operation control module configurable to control operation of one camera in a fully operational mode and operation of the other camera in a partially operational mode and to output an output of the fully operational camera as a dual-aperture camera output, whereby the partially operational mode of the other camera reduces a dual-aperture camera the power consumption in comparison with a full operational mode of the other camera.

Before capture of images, capture aspects of image capture devices (e.g., movement of image capture devices, sounds around image capture devices, GPS times of image capture devices) may be used to identify matching clock times of the image capture devices. Start of image capture by the image capture devices may be restricted using the matching clock times to time-synchronize images captured by different image capture devices.
