1. An indicia reading apparatus comprising:

  • a linear light sensing assembly, the linear light sensing assembly operative for projection of a light pattern and to detect reflected light, the linear light sensing assembly being operative to output a first signal representing the reflected light, the linear light sensing assembly having a first amplifier for amplification of the first signal;

    an area light sensing assembly having an area image sensor array and an imaging lens for focusing an image onto the area image sensor array, the area light sensing assembly having an area field of view and being operative to output a second signal representing reflected light incident on the image sensor array, the area light sensing assembly having a second amplifier for amplification of the second signal;

    wherein the indicia reading apparatus is operative for attempting to decode decodable indicia utilizing one or more of the first signal and the second signal; and

    wherein the indicia reading apparatus is operative so that one or more of a gain of the first amplifier and a gain of the second amplifier is responsive to a representation of the light pattern of the linear light sensing assembly included in the second signal output by the area light sensing assembly.
