System for wireless synchronized capturing, and smart device

A method for operating a smart device, comprising:

• synchronizing, by a processor, a time of single or multiple timers of the smart device or image sensors among multiple smart devices, based on a protocol for time synchronization on wireless communication by using a communication device, wherein the smart device comprises the single or multiple image sensors, the communication device, and the processor;
• and
• controlling, by the processor, shutter opening and closing timing of each image sensor, to keep constancy of shooting time interval and phase, wherein the phase is a remainder obtained by dividing shooting time by the shooting time interval.

A non-transitory computer-readable storage medium having instructions stored therein, which when executed by a processor, cause the processor to:

• synchronize a time of single or multiple timers of a smart device or image sensors among multiple smart devices, based on a protocol for time synchronization on wireless communication by using a communication device;
• and
• control shutter opening and closing timing of each image sensor, to keep constancy of shooting time interval and phase, wherein the phase is a remainder obtained by dividing shooting time by the shooting time interval.
