In a system for updating a contacts database ( 42, 46 ), a portable imager ( 12 ) acquires a digital business card image ( 10 ). An image segmenter ( 16 ) extracts text image segments from the digital business card image. An optical character recognizer (OCR) ( 26 ) generates one or more textual content candidates for each text image segment. A scoring processor ( 36 ) scores each textual content candidate based on results of database queries respective to the textual content candidates. A content selector ( 38 ) selects a textual content candidate for each text image segment based at least on the assigned scores. An interface ( 50 ) is configured to update the contacts list based on the selected textual content candidates.
