Image and Scanner Interface Specification (ISIS) is an industry standard interface for image scanning technologies, developed by Pixel Translations in 1990 (which became EMC Corporation's Captiva Software and later acquired by OpenText). [1]
ISIS is an open standard for scanner control and a complete image-processing framework. It is currently supported by a number of application and scanner vendors.
The modular design allows the scanner to be accessed both directly or with built-in routines to handle most situations automatically. A message-based interface with tags is used so that features, operations, and formats not yet supported by ISIS can be added as desired without waiting for a new version of the specification.
The standard addresses all of the issues that an application using a scanner needs to be concerned with. Functions include but are not limited to selecting, installing, and configuring a new scanner; setting scanner-specific parameters; scanning, reading and writing files, and fast image scaling, rotating, displaying, and printing. Drivers have been written to dynamically process data for operations such as converting grayscale to binary image data.
An ISIS interface can run scanners at or above their rated speed by linking drivers together in a pipe so that data flows from a scanner driver to compression driver, to packaging driver, to a file, viewer, or printer in a continuous stream, usually without the need to buffer more than a small portion of the full image. As a result of using the piping method, each driver can be optimized to perform one function well. Drivers are typically small and modular in order to make it simple to add new functionality to an existing application.
In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to know precise details about the hardware being used.
Java Platform, Standard Edition is a computing platform for development and deployment of portable code for desktop and server environments. Java SE was formerly known as Java 2 Platform, Standard Edition (J2SE).
Tag Image File Format or Tagged Image File Format, commonly known by the abbreviations TIFF or TIF, is an image file format for storing raster graphics images, popular among graphic artists, the publishing industry, and photographers. TIFF is widely supported by scanning, faxing, word processing, optical character recognition, image manipulation, desktop publishing, and page-layout applications. The format was created by the Aldus Corporation for use in desktop publishing. It published the latest version 6.0 in 1992, subsequently updated with an Adobe Systems copyright after the latter acquired Aldus in 1994. Several Aldus or Adobe technical notes have been published with minor extensions to the format, and several specifications have been based on TIFF 6.0, including TIFF/EP, TIFF/IT, TIFF-F and TIFF-FX.
TWAIN and TWAIN Direct are application programming interfaces (APIs) and communication protocols that regulate communication between software and digital imaging devices, such as image scanners and digital cameras. TWAIN is supported on Microsoft Windows, Linux and Mac OS X.
An MFP, multi-functional, all-in-one (AIO), or multi-function device (MFD), is an office machine which incorporates the functionality of multiple devices in one, so as to have a smaller footprint in a home or small business setting, or to provide centralized document management/distribution/production in a large-office setting. A typical MFP may act as a combination of some or all of the following devices: email, fax, photocopier, printer, scanner.
Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems.
A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. Like a flatbed scanner, it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain decoder circuitry that can analyse the barcode's image data provided by the sensor and send the barcode's content to the scanner's output port.
An image scanner is a device that optically scans images, printed text, handwriting, or an object and converts it to a digital image. The most common type of scanner used in offices and in the home is the flatbed scanner, where the document is placed on a glass window for scanning. A sheetfed scanner, which moves the page across an image sensor using a series of rollers, may be used to scan one document at a time or multiple, as in an automatic document feeder. A handheld scanner is a portable version of an image scanner that can be used on any flat surface. Scans are usually downloaded to the computer that the scanner is connected to, although some scanners are able to store scans on standalone flash media.
Scanner Access Now Easy (SANE) is an open-source application programming interface (API) that provides standardized access to any raster image scanner hardware. The SANE API is public domain. It is commonly used on Linux.
JTAG is an industry standard for verifying designs of and testing printed circuit boards after manufacture.
Automatic test equipment or automated test equipment (ATE) is any apparatus that performs tests on a device, known as the device under test (DUT), equipment under test (EUT) or unit under test (UUT), using automation to quickly perform measurements and evaluate the test results. An ATE can be a simple computer-controlled digital multimeter, or a complicated system containing dozens of complex test instruments capable of automatically testing and diagnosing faults in sophisticated electronic packaged parts or on wafer testing, including system on chips and integrated circuits.
The Enlightenment Foundation Libraries (EFL) are a set of graphics libraries that grew out of the development of Enlightenment, a window manager and Wayland compositor. The project's focus is to make the EFL a flexible yet powerful and easy to use set of tools to extend the capabilities of both the Enlightenment window manager and other software projects based on the EFL. The libraries are meant to be portable and optimized to be functional even on mobile devices such as smart phones and tablets.
Enterprise content management (ECM) extends the concept of content management by adding a timeline for each content item and, possibly, enforcing processes for its creation, approval, and distribution. Systems using ECM generally provide a secure repository for managed items, analog or digital. They also include one methods for importing content to manage new items, and several presentation methods to make items available for use. Although ECM content may be protected by digital rights management (DRM), it is not required. ECM is distinguished from general content management by its cognizance of the processes and procedures of the enterprise for which it is created.
VueScan is a computer program for image scanning, especially of photographs, including negatives. It supports optical character recognition (OCR) of text documents. The software can be downloaded and used free of charge, but adds a watermark on scans until a license is purchased.
A file system API is an application programming interface through which a utility or user program requests services of a file system. An operating system may provide abstractions for accessing different file systems transparently.
A dynamic-link library (DLL) is a shared library in the Microsoft Windows or OS/2 operating system.
Windows Image Acquisition is a proprietary Microsoft driver model and application programming interface (API) for Microsoft Windows Me and later Windows operating systems that enables graphics software to communicate with imaging hardware such as scanners, digital cameras, and digital video equipment. It was first introduced in 2000 as part of Windows Me, and continues to be the standard imaging device and API model through successive Windows versions. It is implemented as an on-demand service in Windows XP and later Windows operating systems.
Windows Vista has many significant new features compared with previous Microsoft Windows versions, covering most aspects of the operating system.
Sercos III is the third generation of the Sercos interface, a standardized open digital interface for the communication between industrial controls, motion devices, input/output devices (I/O), and Ethernet nodes, such as PCs. Sercos III applies the hard real-time features of the Sercos interface to Ethernet. It is based upon the Ethernet standard. Work began on Sercos III in 2003, with vendors releasing first products supporting it in 2005.
A kernel is a computer program at the core of a computer's operating system that generally has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components. A full kernel controls all hardware resources via device drivers, arbitrates conflicts between processes concerning such resources, and optimizes the utilization of common resources e.g. CPU & cache usage, file systems, and network sockets. On most systems, the kernel is one of the first programs loaded on startup. It handles the rest of startup as well as memory, peripherals, and input/output (I/O) requests from software, translating them into data-processing instructions for the central processing unit.
