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.
