US 2024/0406576 A1 · APPARATUSES, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR FLICKER REDUCTION IN A MULTI-SENSOR ENVIRONMENT

Abstract

Embodiments of the disclosure relate generally to flicker reduction in a multi-imager environment. Embodiments include methods, computer program products, and apparatuses for producing a near-field illumination using a near-field illuminator, the near-field illumination produced at a defined pulse train. A near-field image sensor may be exposed near the start of a near-field illumination pulse, and a far-field image sensor may be exposed between pulses of the near-field illumination. Some embodiments, additionally or alternatively, are configured for detecting an illuminator switch event, deactivating the near-field illuminator source, and producing, using a far-field illuminator source, a far-field illumination. Upon switching the illuminator source, some such embodiments are configured for exposing a far-field illuminator near the start of the far-field illumination pulse, and exposing a near-field image sensor near the start of the next available far-field illumination pulse. Such image capture may repeat until a task such as barcode reading is successful.

Dependent claims

A method for flicker reduction in a multi-imager environment, the method comprising:

producing a first illumination using a first illuminator source of a plurality of illuminator sources;
exposing a first image sensor during the first illumination;
generating at least one first image based on the exposure of the first image sensor;
exposing a second image sensor such that the exposure of the second image sensor is not during any pulse associated with the first illumination;
generating at least one second image based on the exposure of the second image sensor;
detecting an illuminator switch event;
and
in response to the detection of the illuminator switch event:
deactivating the first illuminator source;
and
producing, using a second illuminator source of the plurality of illuminator sources, a second illumination associated with at least one second illumination pulse, wherein a second field of view illuminated by the second illuminator source is different from a first field of view illuminated by the first illuminator source.
