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.

Electronic device and method for synchronization of videos

A method of camera control for a camera capturing images of a target includes a sequence of at least four steps. The first step determines in real time a location of a drone and a pose of a camera on the drone. The second step, which may occur before or after the first step, determines in real time a location of a reference object, the location of the reference object having a fixed relationship to a location of the target. The third step uses the determined locations to calculate a distance, characterized by magnitude and direction, between the target and the drone. The fourth step uses the calculated distance to control the pose of the camera such that an image captured by the camera includes the target. Controlling the pose of the camera does not require any analysis of the captured image.
