摘要

A portable non-contact label imager captures an image of two-dimensional information indicia (20) on a label (25). The captured image data is decoded by a decoder. The label imager forms a part of a data terminal (10), which includes a keypad (35), display (45) and signature capture pad (40). Upon receipt of a start signal from the data terminal's circuitry, the label imager automatically carries out the steps required to capture the label information indicia. The label imager provides aiming indicia to allow the user to properly aim the camera. A position sensing device determines when the target label is within the camera's depth of field. At that time, the label imager determines the shutter speed required for a correct exposure by measuring the light reflected from the label. The label imager then captures the label image, which is decoded by the decoder. Corresponding output data is then provided to the data terminal (10).
