· Even out the paper document or book pages (especially in the case of thick books). The text lines
should not be skewed by more than 20 degrees, otherwise the text may not be converted properly.
· To get sharper images, focus on the center of the image.
· Enable the anti-shake feature, as longer exposures in poor lighting conditions may cause blur.
· Use the automatic shutter release feature. This will prevent the camera from moving when you
press the shutter release button. The use of automatic shutter release is recommended even if you
use a tripod.
How to improve an image if:
· The image is too dark or its contrast is too low.
Solution: Try using brighter 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 or when taking pictures from a close
distance. Try using brighter lighting. Use a tripod and self-timer to avoid moving the camera when
taking the picture.
If an image is only slightly blurry, the Photo Correction tool in the Image Editor of the OCR Editor
may help get better results. See also: If your document image has defects and OCR accuracy is
low .
· 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 the edge of the image.
· The flash causes glare.
Solution: Disable the flash or try using other light sources and increasing the distance between
the camera and the document.
