Automatic electronic camera for label image capture |
摘要 |
<p>A hand held label reader (10) is capable of illuminating a label (20), capturing a digital image of two-dimensional information indicia (15) on the label, and decoding the digital image to provide decoded output data to a terminal (35). The target label is illuminated by a low variation illuminator that includes a circular LED array mounted behind a plano-concave dispersing lens. The automatic electronic camera, which includes a CCD camera and control circuitry, uses three images to adjust the intensity of the digital image and store a properly exposed image of the label in video RAM.</p> |
