Method to limit decode volume

A method for decoding encoded data appearing within a field of view (FOV) of an indicia reader, the method comprising:

• providing, by an illumination assembly, first illumination to a first region of the FOV during a first period of time;
• capturing, by an imaging assembly associated with the FOV, and during the first period of time, first image data representative of an environment appearing within the FOV;
• providing, by the illumination assembly, second illumination to the FOV during a second period of time;
• capturing, by the imaging assembly, second image data during the second period of time;
• responsive to determining a presence of an indicia within the first region of the FOV, at least one of (i) transmitting the second image data to a decoder module, (ii) decoding the indicia by the decoder module, or (iii) generating a successful decode operation;
• and
• responsive to determining a presence of the indicia within the second region of the FOV, at least one of (i) not transmitting the second image data to the decoder module, (ii) not decoding the indicia by the decoder module, or (iii) not generating a successful decode operation.

A system for decoding encoded data appearing within a field of view (FOV) of an indicia reader, the system comprising:

• an imaging assembly configured to capture images of the FOV of the indicia reader;
• a first illuminator configured to provide first illumination to a first region of the FOV, the FOV further having a second region of the FOV that does not receive the first illumination from the first illumination assembly;
• and
• a processor and computer-readable media storage having machine readable instructions stored thereon that, when the machine readable instructions are executed, cause the system to:
• provide, by the first illumination assembly, first illumination to a first region of the FOV, the FOV further having a second region of the FOV that does not receive the first illumination from the first illumination assembly;
• capture, by the imaging assembly, image data representative of an environment appearing within the FOV;
• responsive to determining a presence of an indicia within the first region of the FOV, at least one of (i) transmit the image data to a decoder module, (ii) decode the indicia by the decoder module, or (iii) generate a successful decode operation;
• and
• responsive to determining a presence of the indicia within the second region of the FOV, at least one of (i) not transmit the image data to the decoder module, (ii) not decode the indicia by the decoder module, or (iii) not generate a successful decode operation.
