Loading digital camera files

You can load images containing text produced by digital cameras. These might be photographs of printed documents, posters or notices. We recommend viewing and exporting the result as Plain text.

Such digital camera images should have at least 2 megapixels. This table shows the recommended minimum point size of text for different megapixel values, assuming you follow the guidance given at the end of this topic.

Image size:

A4 (8.27″ x 11.69″)

A5 (8.27″ x 5.85″)

  • straightening text lines

To process digital camera images

  1. Connect the camera to your computer and save the photographed documents on your computer.

  2. Select the Load Digital Camera Files command or the Load as digital camera image check box to run the algorithm developed for digital camera images.

To achieve good results with digital camera images

  1. Lighting: Clear, even lighting with good contrast is important (no shaded parts).
    If the white Balance setting on your camera is not automatic, set it manually according to the current light source. This is especially important if the photo is taken using artificial light.

  2. Stable camera position: Use a tripod or other steadying device.

  3. Camera axis: perpendicular to the page.

  4. Correct distance: The minimum distance is around 25-50cm / 10-20 inches. In macro mode it can be much less.

  5. Resolution (pixel density): Depends on the camera resolution, distance between camera and page and character size. The higher the resolution, the more detailed the image.

Correct focusing is needed to get a sharp image.
