Image and Scanner Interface Specification
ISIS ( Image and Scanner Interface Specification ) is an industry standard interface ( API ) for image scanning technologies. It was developed in 1990 by what was then Pixel Translations (now EMC Captiva ).
ISIS can be seen as the "big brother" of the TWAIN standard, which for a long time represented a quasi-standard for scanners in the home. ISIS-compatible scanners usually use the SCSI- 2 interface (newer ones but also USB ), while TWAIN scanners nowadays mostly use USB (formerly the parallel interface ).
ISIS has more setting options than TWAIN, is faster than this and also covers some aspects of image display and handling for the client application. Most of the major scanner manufacturers, including InoTec, Avision , Kodak , Canon , Hewlett-Packard , Brother and Fujitsu , use the ISIS interface for their corporate and high-performance scanners.
The ISIS architecture is a changeable architecture based on modules and software components. It can perform specific exposure functions (such as image acquisition, file conversion, data extraction and read-write commands). The ISIS architecture allows new modules to be added without requiring system-wide changes.
The ISIS architecture is characterized by high compatibility: ISIS-compatible drivers are available for more than 300 scanner models, most of these drivers have been certified by EMC Captiva . The ISIS architecture is also the basis for the public domain standard AIIM (The Association for Information and Image Management) MS61, developed in 1996.
