    • Make sure that document is well lit.
    • Avoid strong shadows as well as glares (especially with glossy documents).
    • Use the flash with matt originals.
  2. Document should be flat (not curved or folded).
  3. Background should be uniform and contrast to original to make sure that Smart Crop (auto cropping) will work well.
  4. Use Stabilization switched ON in SmarCamera Settings during shooting especially in low light conditions.
  5. Make sure that document fits camera viewfinder (window).
  6. Hold device parallel (as much as possible) and centered to original document.

First of all — feel free to change document color mode as much as you want. Since SharpScan edit all documents in nondestructive mode you can always revert to original image. You can change document color in two ways:


  1. Open the page you want to reprocess (rescan).
  2. Tap on color profile icon on bottom tool-bar ( one of SharpScan BW color profile, SharpScan Grey color profile ,SharpScan Color color profile, SharpScan Original color profile )

    Used color profile will be set as new default and will be used on next scan (until you change it again).

In batch mode.

Please read about in “How to change several documents/pages at once” article (see below). You can watch our document manual adjustments video tutorial where color changing process well covered.

This is highly depending on your future documents usage. Anyway, feel free to experiments since you can always revert document to original state. Below our general recommendations about processing profiles usage.

  • B&W (Black and White). SharpScan BW color profile
    Use it when you care about document size and text only. It produces clear tiny black and white documents with favour to the text area and disregard images and photos. Could be useful when you need to send rather big documents over low quality connection (like cellular network). Also take into account that image will have lossless compression.

  • Gray. SharpScan Grey color profile
    Near the same as B&W but optimized for human eye readability. Using lossy Jpeg compression (level could be set in settings).

  • Color. SharpScan Color color profile
    Use Color processing profile when you care about document color information. Better fits for documents with color charts, photos, magazines etc. Using lossy ÏJpeg compression (level could be set in settings).

  • Original. SharpScan Original color profile Use it only if anything else fits your needs. Doesn’t process documents at all (only crop). Using lossy Jpeg compression (level could be set in settings)

Please watch our document manual adjustments video tutorial where color changing process well covered.

Smart Camera is aimed to provide full auto mode shooting and reduce inintentional shooting errors. But sometimes this leads to some inconvenience especially in bad lighting conditions. If you have problems complaining Smart Camera interactive demands border or simply in a rush you can:

  • Just ignore the messages and tap on camera button or document preview in camera viewfinder. In this case camera will take a shot not waiting when document will be found and handshaking sensor will be ignored.
  • If you completely don’t like new scanning method you can easily switch it off by tapping on radar icon SharpScan Smart Camera on (it will be grey out to SharpScan Smart Camera off) or adjust it more precisely in SharpScan SettingsSmart Camera section.

In SharpScan you can easily copy or move any page(pages) to any existing document. Just follow the steps below.

  1. First of all, make sure that you have a «destination» document where you want your pages to be copied (moved). If you don’t have it just create new one from Camera SharpScan scan document from Camera or Album SharpScan scan document from Album.
  2. Open document which contains page you want to copy.
  3. Tap on Select menu and select the page(s) you want to copy.
  4. Tap on Folder icon SharpScan copy pages or documents (bottom menu bar).
  5. Select desired action: Copy or Move.
  6. Select the «destination» document (from step 1) for your pages.
  7. Tap on Done. Pages will be copied or moved to selected document.

“Smart Crop” is our proprietary artificial intelligence technology allowing to automatically detect document boundaries and cut it out from background with high precision.
This means that in most cases you don’t need manually adjust document boundaries – this will be done in full auto.

If shooting conditions was not good, or in some cases when document or background have complicated content, “Smart Crop” function could offer to manually correct document boundaries. Follow our recommendations for perfect scanning (see above) to make sure that you’ll get best possible results in full auto mode.

We recommend using this option in low-lit conditions.
There are very few shooting problems we can’t (currently) correct. And one of them is defocusing. Usually it happens due to camera tremor during shooting and especially critical in low-lit conditions.
To mitigate this, we implement “stabilization” feature to our camera. It works very simple – camera waits until trembling will be reduced to appropriate level and only after that makes a shot.
To reduce camera tremor, try to hold hand still as much as possible or use any kind of support (stand or tripod).

Use this option with any processing preset (except Original) if original image contain strong shadows. In most cases it could help reveal a lot of additional information.
“Shadows” processing will work more effectively, if processed document was cropped accurately without any additional dark fragments from background.
Please avoid use this option on documents without strong shadows since it could lead to loose some details on dark areas.

New compression setting will be applied during document reprocessing (modification). To recompress document (not altering cropping and profile settings) do the following.

  1. Open desired page.
  2. Tap on color profile icon (could one of SharpScan BW color profile, SharpScan Grey color profile ,SharpScan Color color profile,SharpScan Original color profile ).
  3. Tap on Done button. New compression level will be applied, document size will be changed.

Do not be afraid to change compression level over and over again. Each time document will be compressed from original so there will be no compression errors accumulation. To recompress several pages or documents use batch processing.

When you have a lot of multipage documents scanned sometimes you need to process them in batch. Currently in batch mode you can: change color profile, rotate document clockwise or counterclockwise, redetect document boundaries. To process documents/pages in batch mode please follow the steps below.

  1. Select documents (or pages inside document) by tapping on Select button and taping on appropriate items. Use Select All icon (SharpScan select all) for quick selection of multiple items.
  2. Tap on Batch processor icon (SharpScan batch process).
  3. On Bach processor screen select options you want to change — e.g. Color profile, Rotation, Boundary redetection.
  4. Tap on OK. You’ll see the progress on documents (page) icons.

You can also watch our “batch processing video tutorial”.

Consider using Black and White processing profile SharpScan BW color profile.
In most cases it 10-20 times (depend in document content) smaller than Gray or Color.
If document colors are crucial use lowest acceptable Jpeg quality (in Setting menu, Export section).
