SECTION 7: ADJUSTING THE

IMAGE QUALITY

The recognition results depend a great deal on the image quality of

your documents. If you're scanning very low-quality documents,

Readiris will not be able to recognize them properly.

The reason for this is that Readiris works by converting pictures of

text characters into actual text characters. If your documents are

too dark, the characters fade into one another and create black spots.

If your documents are too light, the text characters might be broken.

Consequently, Readiris will not be able to recognize them.

Example 1: text is too dark

Here, the letter shapes begin to fill in and become fuzzy. Letters like

a, e, and o are almost completely blurred.

Example 2: text is too bright

Here, the text characters start to show gaps and incomplete shapes.
