ABBYY FineReader 12 Sprint enables you to recognize pictures of documents taken with digital cameras. This article explains how to take photographs that are well suited for recognition.
Note: You can find technical information about your camera in its owner's manual or other accompanying documentation.
Before photographing a document, make sure that:
- the entire page fits in the shot
- the lighting is even and there are no shadows on the document
- the lens is parallel to the page and is directed at the center of the page; if the page is bent or creased, try to even it out.
Recognition quality depends on the quality of the image. High-quality images yield better recognition quality.
How to improve an image if
- the photograph is too dark and the contrast is too low
Solution: Try to improve the lighting. If that is not an option, try setting a lower aperture value.
- the image is not sharp enough
Solution: Autofocus may not work properly in poor lighting. Try using brighter lighting. If adjusting the lighting doesn't help, try using manual focus.
- a part of the image is not sharp enough
Solution: Try setting a higher aperture value. Take pictures from a greater distance at maximum optical zoom. Focus on a point between the center and an edge of the image.
- the flash causes glare
Solution: Turn off the flash or try using other light sources and increasing the distance between the camera and the document.
