Abstract: At least some embodiment of the present invention are directed to mean for operating an illumination assembly associated with a group of imaging devices. An example method includes causing each of a plurality of imaging devices to capture image data during a group acquisition operation, each of the plurality of imaging devices has (i) a respective delay until a start of an exposure duration, (ii) the respective exposure duration, and (iii) a total operation duration. The method also includes causing an illumination assembly to transition from a first state to a second state based on a shortest delay of the imaging devices and further causing the illumination assembly to transition from the second state to a third state based on a longest total operation duration of the imaging devices.

Abstract: At least some embodiments are directed to systems and methods to optimize relative signal delays in vision systems having illumination assemblies separate from a host. In an example embodiment there is a system that includes a host device having, an imaging assembly coupled to the host device and operable to capture image data, and an illumination assembly coupled to the host device and operable to provide illumination. The system is configured such that the host transmits, to the imaging assembly, a series of exposure signals causing the imaging assembly to capture a series of frames and transmits, to the illumination assembly, a series of illumination signals causing the illumination assembly to provide the illumination as a series of strobes. Thereafter the host evaluate each frame to identify a peak-brightness frame and from that, based on a corresponding illumination signal, determines an appropriate relative signal delay for future operations.
