Abstract[English]
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.[French]
L'invention concerne un dispositif électronique comprenant un circuit. Le circuit génère un signal de synchronisation. Le circuit commande l'attaque d'un ou de plusieurs dispositifs émetteurs de lumière sur la base du signal de synchronisation pour générer un motif d'impulsions lumineuses alternées. Le circuit acquiert en outre une pluralité de vidéos du motif d'impulsions lumineuses alternées auprès d'une pluralité de dispositifs d'imagerie. Le ou les dispositifs émetteurs de lumière sont positionnés dans un champ de vision de chaque dispositif d'imagerie de la pluralité de dispositifs d'imagerie. Le circuit détermine, dans chaque vidéo de la pluralité de vidéos, une image qui comprend une partie spécifique du motif d'impulsions lumineuses alternées. L'image déterminée dans chaque vidéo de la pluralité de vidéos correspond au même instant. Le circuit synchronise la pluralité de vidéos sur la base de la détermination.
