摘要: There is set forth herein an indicia reading apparatus comprising two or more light sensing assemblies. In one embodiment, the can comprise a linear assembly and area assembly, be operative to determine range between indicia. apply range-assisted gain data output by of increase likelihood improve expected read time.
