SYSTEM AND METHOD FOR READING OPTICAL CODES ON REFLECTIVE SURFACES WHILE MINIMIZING FLICKER PERCEPTION OF PULSED ILLUMINATION

摘要

Methods and systems are disclosed for improved operation of readers (10) of optical codes (45) presented on electronic display screens (42) or other highly reflective surfaces. Certain configurations include controlling image exposure and illumination pulse timing so as to avoid or minimize the perception of flicker of the pulsed illumination by a user or bystander while implementing methods for reading optical codes presented on electronic display screens or other highly reflective surfaces.
