Devices, Systems, and Methods for Processing Indicia on Different Types of Media

A method for operating an imaging device having an imaging assembly configured to capture image frames via a rolling shutter imaging sensor and an illumination assembly configured to emit illumination light over at least a portion of a field of view (FOV) of the imaging assembly, comprising:

• operating, the imaging apparatus, in a first mode where during the first mode the imaging assembly captures a first-mode frame such that an intensity of the illumination light varies during a capture of the first-mode frame;
• and
• determining, by analyzing the first-mode frame, a media type appearing within the FOV of the imaging assembly based on one of (i) a lack, in the first-mode frame, of an optical signature associated with varying the intensity of the illumination light during the capture of the first-mode frame or (ii) a presence, in the first-mode frame, of the optical signature associated with the varying the intensity of the illumination light during the capture of the first-mode frame.

A tangible machine-readable medium comprising instructions that, when executed, cause an imaging apparatus, having an imaging assembly configured to capture image frames via a rolling shutter imaging sensor and an illumination assembly configured to emit illumination light over at least a portion of a field of view (FOV) of the imaging assembly, to:

• operate in a first mode where during the first mode the imaging assembly captures a first-mode frame such that an intensity of the illumination light varies during a capture of the first-mode frame;
• and
• determine, by analyzing the first-mode frame, a media type appearing within the FOV of the imaging assembly based on one of (i) a lack, in the first-mode frame, of an optical signature associated with varying the intensity of the illumination light during the capture of the first-mode frame or (ii) a presence, in the first-mode frame, of the optical signature associated with the varying the intensity of the illumination light during the capture of the first-mode frame.
