VueScan is a scanning program that works with most flatbe and film scanners in place of software supplied by the equipment manufacturers. It is claimed to produce scans of excellent color fidelity and color balance and save them in any of several file formats, including optical character recognition (OCR) of text. It provides a number of features not available with many manufacturer-supplied packages, and provides a single consistent user interface for all scanners (and digital cameras) under Linux, Mac OS 9 and OS X (10.2 through 10.5), and Windows (95 through Vista). Older non-Windows systems may require downloading discontinued versions, which are still available.
