1. A portable data collection device comprising:

  • a) an image sensor, including an array of photosensor elements generating a signal representative of an image of a target area;

    b) an optic system positioned to focus illumination reflected from the target area onto said image sensor;

    c) image buffering circuitry coupled to said image sensor, receiving said signal and buffering a digital image representation of the target area;

    d) decoder circuitry coupled to said image buffering circuitry for decoding a dataform in the image area and providing a decoded representation of said dataform;

    e) an audio input circuit including a microphone providing a signal representative of operator speech commenting about the target area and analog to digital circuitry for providing a digital audio representation of such speech;

    f) output port circuitry coupled to said decoder circuitry and said audio input circuitry for outputting at least one of said decoded representation and said digital audio representation; and

    g) selection circuitry coupled to said decoder circuitry and said image compression circuitry for selectively determining whether to output the decoded representation or the digital audio representation.
