A portable non-contact label imager captures an image of two-dimensional information indicia on a label. The captured image data is decoded by a decoder. The label imager forms a part of a data terminal, which includes a keypad, display and signature capture pad. 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.
[ What is claimed is:] [1.] A method for operating a non-contact imager for automatically determining whether a surface is within the operating range of the imager and for capturing an image of information indicia on the surface when the surface is within the operating range of the imager, comprisin
[ What is claimed is:] [1.] A method for operating a non-contact imager for automatically determining whether a surface is within the operating range of the imager and for capturing an image of information indicia on the surface when the surface is within the operating range of the imager, comprising the steps of:receiving a user-initiated start signal;in response to said user-initiated start signal, determining if the distance between said imager and said surface is within a predetermined range of distances, said predetermined range of distances corresponding to the operating range of the imager;in response to said surface not being within said predetermined range of distances, again determining if the distance between said imager and said surface is within said predetermined range of distances; andin response to said surface being within said predetermined range of distances, performing the steps of:determining a proper shutter speed for said imager;obtaining an image of said information indicia using said proper shutter speed, thereby providing image data; andproviding output data corresponding to said image data.
