发明名称 Methods and Apparatus for Providing a Changing Field of View in Image Based Bar Code Scanning
摘要 Systems and techniques for image based bar code scanning. A rotating spinner is positioned to reflect images to an imaging device within the scanner so that a field of view of the scanner encompasses images reflected by the spinner to the imaging device. The rotation of the spinner causes the field of view of the scanner to change. Fixed mirrors positioned and oriented to reflect images to the spinner and from the spinner to the imaging device further shift the field of view of the scanner as the rotating spinner causes images reflected from different mirrors to be delivered to the imaging device.
