Abstract: Methods and systems for avoidance of unintended indicia scanning are disclosed herein. An example system may include an imaging device comprising: (1) one or more image sensors; (2) a processing assembly communicatively coupled to the one or more image sensors and configured to: (i) instruct the one or more image sensors to capture the image data including a plurality of image frames over a FOV, (ii) decode an indicia in an initial image frame of the plurality of image frames to generate decoded indicia data of the indica, (iii) determine a first location associated with the indicia in the initial image frame, (iv) determine a second location associated with the indicia in a subsequent image frame, (v) determine whether a positional difference between the second location and the first location exceeds a threshold value, and (vi) transmit the decoded indicia data of the indicia to a host processor.

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.
