System and methods for situational adaptive image capture improvements for barcode reading
A method is disclosed for adjusting imaging parameters of a bioptic barcode reader. The method includes capturing, by an imaging assembly, an initial image of a target object having an indicia thereon. The imaging assembly captures the initial image according to an initial imaging parameter. The method further includes attempting to decode the indicia from the initial image, and responsive to being unable to decode the indicia, detecting a substantially static presence of the target object within a field of view (FOV) of the imaging assembly. The method then includes, responsive to detecting the substantially static presence of the target object within the FOV, adjusting the initial imaging parameter to a subsequent imaging parameter, wherein the subsequent imaging parameter is different than the initial imaging parameter.
