bitmapped character A character image made up of a pattern of dots that exists in a

computer file or in memory as a bitmap. Bitmapped

characters cannot be interpreted by a computer. In order for a

computer to use bitmapped characters in a word processor or

spreadsheet, the characters must first be interpreted by an

OCR application and translated into ASCII text.

bold text Text with the bold attribute looks like this. See also text

style.

brightness The relative amount of light or darkness reflected from an

image. A scanner’s brightness control is used in Pro OCR to

adjust for pages that are either too light or too dark.

broken character A character with one or more missing pieces, such as a

missing serif, stem, or cross bar. For example, a broken lower

case ‘e’ might not have a fully closed loop, which could

cause it to be misrecognized. Problems with broken

characters can be reduced by using the brightness setting in

Pro OCR to darken the image when scanning. Compare with

heavy character and touching characters.

built-in dictionary The dictionary that Pro OCR automatically loads and uses

whenever Recognize is done. The built-in dictionary is used

to enhance Pro OCR’s recognition accuracy and also to find

misspelled words in the document. Compare with

supplementary dictionaries and user dictionary.

CCITT Abbreviation for Consultative Committee on International

Telegraphy and Telephony; an international committee that

character Any symbol that has a widely understood meaning and thus

can convey information, including alphabetic, numeric,
