Editing Barcode reader (section)

==== Camera-based readers ====
Two-dimensional [[machine vision|imaging scanners]] are a newer type of barcode reader. They use a camera and image processing techniques to decode the barcode.

'''Video camera readers''' use small video cameras with the same CCD technology as in a CCD barcode reader except that instead of having a single row of sensors, a video camera has hundreds of rows of sensors arranged in a two dimensional array so that they can generate an image.

'''Large field-of-view readers''' use high resolution industrial cameras to capture multiple bar codes simultaneously. All the bar codes appearing in the photo are decoded instantly (ImageID patents and code creation tools) or by use of plugins (e.g. the [[Barcodepedia]] used a flash application and some web cam for querying a database), have been realized options for resolving the given tasks.
