Abstract: A new technology is provided for a portable bar code verification reader and is designed to create a video image of a bar code label in accordance to strict industry bar code verification standards. The barcode verification reader will effectively capture a bar code label and then send the resulting video image to a computer. The resulting bar code label quality may be displayed on the portable verification reader via one or more LED's, an embedded display monitor, or the like.

Abstract: A barcode image processing system which processes video signals including video data representing images of barcode labels to be decoded and verified. A video signal containing video data representative of successive images of a plurality of barcode labels is processed to extract the video data and the horizontal and vertical synchronization signals from the video signal. A digitalization circuit is provided which digitalizes the video signal over a varied threshold voltage. The range or deviation of the threshold voltage which yields decodable video data is used as a measure of a quality of a barcode label. A gate trigger signal is generated which is synchronized to the vertical synchronization signal and which controls when a barcode decoder decodes video data for a horizontal line taken from a barcode image.
