1. An apparatus for synchronizing multiple devices, the apparatus comprising:
at least one memory;
instructions; and
processor circuitry to execute the instructions to at least:
obtain, in a time duration, first images using a first trigger frequency and second images using a second trigger frequency, the first trigger frequency representing a first number of pulses in the time duration, the second trigger frequency representing a second number of pulses in the time duration, the second number of pulses different from the first number of pulses;
identify a first number of time units between a first time corresponding to a first one of the first images and a second time corresponding to a first one of the second images, the first number of time units defining a first time window; and
in response to the first time window exceeding a threshold, adjust the second trigger frequency by adjusting the second number of pulses in the time duration such that a subsequent time window satisfies the threshold.
