1244.1 Barcode DetectionThis image filter recognizes the barcodes in the scanned images. Refer to theapplication’s operating manual how to use the barcode.If the barcodes cannot be recognized properly, the quality of the scanned images canbe improved by using another image filter, examples of which are given below.In order to obtain the ideal image quality and speed for barcode detection, it isrecommended that the settings of the image filters be adjusted while scanning anactual document.[Barcode Detection Properties] dialog boxSymbologies to checkIf the type of barcode to be recognized is known ahead of time, set the checkboxes at the sides of the barcode types which will not be used to off. The smallerthe number of barcodes selected, the faster the processing.OrientationWhen Horizontal or Vertical is selected, barcodes inclined less than 15 degreesfrom the horizontal or vertical are detected. To recognize barcodes inclined ata greater angle, select [Diagonal]. [Vertical] barcodes are detected slightly moreslowly. Recognizing inclined barcodes takes even longer. If the barcodeorientation is known ahead of time, the processing speed is improved byselecting only the required orientation. Conversely, if the barcode orientation isnot known, all the orientations must be selected.Decode SymbolThe data will not appear as ASCII character strings with some barcode typessuch as Code128. Special characters are used for Code39 and other barcodetypes. When [Decode Symbol] is selected, the data of these barcodes ischanged into readable ASCII character strings.IMPORTANT NOTE:• It is recommended that Decode be enabled unless it is clear that the barcodedetection results must not be converted into ASCII character strings.Deskew This straightens out the image skew.Noise Removal This reduces the image noise.Line Removal This restores the barcode lines.Smooth This smoothes out the barcode lines.
