Indicia reading terminal including frame processing

摘要

There is described an indicia reading terminal (1000) that can be operative to process a frame of image data for attempting to decode a decodable indicia (15). A frame can be a frame that is among a succession of frames for subjecting to processing subsequent to and during a time a trigger signal is active. Such a succession of frames can include zero or more binned frames, zero or more unbinned frames, zero or more windowed frames, and zero or more unwindowed full frames. An indicia reading terminal (1000) can also include a variable focus imaging lens (1110). Control of the variable focus imaging lens can be provided so that during an exposure period for a binned frame the variable focus imaging lens (1110) is set to a short range focus setting and further so that during an exposure period for a windowed frame the variable focus imaging lens is set to a long range focus setting.
