Information processing method, information processing device, and recording medium

An information processing method, executed by an information processing device operable as a first imaging device and a second imaging device in a video system that images a target object by using the first imaging device and the second imaging device,

• wherein when the information processing device is the first imaging device, the information processing device executes:
• acquiring a first elapsed time indicating an elapsed time after the first imaging device starts recording;
• requesting the second imaging device to transmit a second elapsed time indicating an elapsed time after the second imaging device starts recording;
• acquiring a required time to receive the second elapsed time after the requesting;
• and
• 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,
• wherein when the information processing device is the second imaging device, the information processing device executes:
• acquiring the second elapsed time and transmitting the second elapsed time to the first imaging device in response to the requesting.

An information processing device, operating as a first imaging device in a video system that images a target object by using the first imaging device and a second imaging device, the information processing device comprising:

• a processor, configured to:
• acquire a first elapsed time indicating an elapsed time after starting recording;
• request the second imaging device to transmit a second elapsed time indicating an elapsed time after the second imaging device starts recording, and receiving the second elapsed time;
• acquire a required time to receive the second elapsed time after the requesting;
• and
• based on the first elapsed time, the second elapsed time, and the required time, calculate 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.
