Abstract
An electronic device including circuitry is provided. The circuitry generates a synchronization signal. The circuitry controls drive of one or more light-emitting devices based on the synchronization signal to generate a pattern of alternating light pulses. The circuitry further acquires a plurality of videos of the pattern of alternating light pulses from a plurality of imaging devices. The one or more light-emitting devices are positioned in a field of view of each of the plurality of imaging devices. The circuitry determines a frame in each video of the plurality of videos that includes a specific portion of the pattern of alternating light pulses. The determined frame in each of the plurality of videos corresponds to the same time instant. The circuitry synchronizes the plurality of videos based on the determination.
