Batch Scanning
Automated document capture. The order of processes that are applied to the batch are predefined in a configuration file.
Bitmap
Digital representation of a document.
Black and white pictures have one bit per pixel. The logical state 1 equals black and the logical state 0 equals white. This scheme is primarily used in printing technology, however, other schemes may also be found.
Gray- and color information is similarly coded. Each pixel is represented through one or more bitmaps.
bitonal
The term describes bitmaps that only contain black and white information.
Book Scanner
See Planetary Scanner.
BSCAN

CCITT G3 and G4
CCITT defined these data compression standards for loss-free data compression. These standards are used in fax machines and are also widely used in the imaging industry. CCITT G3 und G4 are basically either one-dimensional or two-dimensional run length encoding. The shorter the codes, the higher the statistical probability of success for a given run will be.
Clipping Area
The part of a document which is to be processed or scanned. A clipping area is always smaller than the whole document.
D
Data Compression
A method to reduce the file size without discarding information. In our industry, the term data compression usually refers to the compression of images.
deskew
Automated or software-assisted correction of the skew angle of a misfed document after scanning.
despeckle
Automated or software-assisted noise reduction of bitonal documents. After scanning, documents usually have some speckles (black or white pixels) that are isolated and therefore rarely have information in them. These are called speckles. Despeckle removes speckles.

I
ICC profile
The reproduction of a document is a complex process; and at least three input and output devices are involved in this process: scanner, screen and printer. Each device handles colors of the image in a different way. There are many reasons for that: the devices support different color spaces (for example, CMYK or RGB) or they use different (wider or narrower) ranges of colors. When scanning documents further problems occur: Ambient light characteristics or temperature fluctuation of the device can lead to deviations in the color fidelity. This is especially relevant for open scanning systems like planetary scanners or flatbed scanners with open lid, because the documents are confronted with continuous change of light. The goal of the color management is that the scanned and printed document features at the end the same color quality as the original document.
To reduce all input and output devices to a common color denominator, the so-called ICC device profiles are calculated. Such profiles describe the color spaces and how devices should reproduce them. In order to profile the devices the special profiling software is required.
For this purpose, Image Access has developed an online tool Scan2ICC.
Image File
A file that contains information how to produce an image on the screen. Image files are ususally bitmap oriented.
Image Processing
Image Processing is the adaptation, modification and interpretation of the information in a scanned document.

PPM
Abbreviation for Page Per Minute.
It specifies the performance of a scanner. US-letter sized paper is generally used.
R
Resolution
Resolution is measured in dots per inch [dpi]. Each dot is separately scanned or printed. The higher the resolution is, the more fine details will be found in the scanned or printed document. A higher resolution also results in a higher amount of data. If uncompressed, doubling the resolution results in four times more data.

A standard interface for data transfer between the host and peripheral devices. The SCSI bus can be inside the host only or extended via cable to external devices. Mass storage devices and some scanners use this interface.
Simplex Scanner
Scanner that can only scan one side of a document in one pass. Scanning of the other side usually requires flipping the page.
Skew
Every scanned document has some skew compared to its perfect angle, due to imperfections in the feeder/paper pass. Automated or software-assisted correction of the skew angle of a misfed document after scanning is called deskew.
Speckle
Noise that is part of the scan due to physical imperfections. Speckles not only produce unwanted grayish looks, they also produce a lot of extra data after compression. The method used to remove speckles is called despeckle.
Stitching
Stitching is a process whereby images created by several cameras within a large format scanner are joined into one seamless image.
T
TCP/IP
Abbreviation for Transmission Control Protocol/Internet Protocol. A collection of protocols that define the basic workings of the features of the Internet.
