Illumination control for imaging systems with multiple image sensors

An imaging method, comprising:

• operating a first illumination source associated with a first image sensor, based on a first illumination pulse train;
• determining a first exposure period of a second image sensor;
• and
• modifying one or more characteristics of the first illumination pulse train to accommodate the first exposure period of the second image sensor, wherein modifying the one or more characteristics of the first illumination pulse train comprises inserting at least one additional illumination pulse in the first illumination pulse train such that one of a start time period or an end time period of an illumination period of the at least one additional illumination pulse is aligned with a respective one of a start time period or an end time period of the first exposure period of the second image sensor.

An apparatus, comprising:

• a memory configured to store executable instructions;
• and
• one or more processors configured to execute the executable instructions to:
• control operation of a first illumination source associated with a first image sensor, based on a first illumination pulse train;
• determine a first exposure period of a second image sensor;
• and
• modify one or more characteristics of the first illumination pulse train to accommodate the first exposure period of the second image sensor by inserting at least one additional illumination pulse in the first illumination pulse train such that illumination of the first image sensor corresponding to the at least one additional illumination pulse temporally overlaps an autofocus period of the second image sensor.
