  • Publication number: 20230409854
    Abstract: Systems and methods of conducting a bar code scan using an imaging-based bar code scan device are provided. In one exemplary embodiment, a method is performed by an imaging-based bar code device that includes processing circuitry, an optical lens assembly having an image sensor and an optical lens with a focused region at a certain distance in front of the optical lens along an optical axis of the optical lens, a plurality of light emitting elements configured proximate the optical lens and laterally offset from the optical axis. The method includes sending, by the processing circuitry, to each light emitting element, an indication to enable that light emitting element to project a light beam towards the optical axis in the focused region so that the light beams overlap when a target bar code is in the focused region and nonoverlap when a target bar code is outside the focused region.
