Methods and apparatus for positioning an optical code for imaging scanning

摘要

An apparatus and methods are presented for improving image scanning. A point of sale terminal apparatus, including an imaging scanner, provides information to an operator indicating the optimal scanning position for an optical code for efficient first pass scanning by the imaging scanner. The information includes real-time video from an image capture device of the imaging scanner displayed on an operator's display device.

主权项

1. A point of sale terminal comprising:
a display device operable to display text and video data to an operator of the point of sale terminal; a computer peripheral network operable to communicate with peripherals attached to the point of sale terminal; first processing elements operable to communicate with and control peripherals attached to the computer peripheral network and to control the display device; and an imaging scanner for scanning an optical code where the imaging scanner is connected to the computer peripheral network, the imaging scanner including: an image capture device operable to capture an image and further operable to capture continuous images to produce a video stream; and second processing elements operable to analyze captured images to extract data from the optical code and further operable to send the video stream over the computer peripheral network; and where the first processing elements are further operable to receive the video stream from the imaging scanner, display the video stream on the display device and provide instructions for optimal positioning of the optical code for scanning.
