Notes About OCR Properties

  • You can configure up to five areas per form.

  • You can configure one anchor area per form.

  • The image data to be scanned in the form must meet the following conditions:

  • The image data has been created with the SLNX Scan & Capture.

  • The file format is BMP, GIF, JPEG, TIFF, TIFF-F, or PNG.

  • The image data is stored in a local folder.

  • The number of pixels is between 200 x 350 and 7016 x 9921.

  • The recommended minimum resolution of image data scanned to the form is 200 dpi. The recommended resolution when using the position correction function with anchor specification is 400 dpi.

  • To delete the configured area, right-click the Zone OCR area or anchor, and select [Delete]. A deleted area cannot be restored.

  • When you configure an anchor, the position is corrected, and the character recognition rate improves. The configured anchor must meet the following conditions.

  • A string that exists in both the form and scanned image data are selected as the anchor.

  • The anchor area has a string. If there is no text, the position is not corrected.

  • The string in the anchor area and the string in the same position on the scanned image data are the same.

  • The string configured at the anchor area and the string with the same content are within 20 mm from the top, bottom, left, and right of the area.

  • The page number and document name on the header are not specified as the anchor area. The page number, document name on the header, and other similar information cannot be used as an anchor.

  • When the Zone OCR area or anchor is selected, the mouse cursor changes to a two-headed pointer in the four corners of the area and near the center mark on each side. Drag the mouse when this cursor is displayed to enlarge or reduce the area.

  • When Japanese is selected for the OCR language, the following characters can be recognized:
