Patent ID: 11928546
Assignee: DATALOGIC IP TECH, S.R.L.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A code reader, comprising:
a first imager and a second imager configured to capture an image with different field of views, wherein the first imager has a near FOV and the second imager has a far FOV;
a first illuminator and a second illuminator each configured to project a different illumination pattern visible to a user;
a processor operably coupled to the imagers and the illuminators, the processor configured to:
determine a target distance for an object from the code reader;
activate the first imager and the first illuminator as a receiver pair with the second illuminator not active, responsive to detecting the target distance being less than a first distance threshold indicative of the object being in a near field;
activate the second imager and the second illuminator as a receiver pair with the first illuminator not active, responsive to detecting the target distance being greater than a second distance threshold indicative of the object being in a far field, wherein the first illuminator and the second illuminator project a different pattern substantially matching dimensions of the corresponding field of view for its receiver pair such that the respective illumination pattern that is visually presented to the user changes its shape depending on which imager is selected as the active imager; and
decode an optical code using an image captured by the selected receiver pair.
