Terms	Definitions
	A camera incorporating an image sensor which outputs a digital signal
digital still camera (DSC)	representing a still picture, or records a digital signal representing a still picture
	on a removable medium, such as a memory card or magnetic disk.
dynamic range	cf. ISO DSC dynamic range, colour gamut, luminance ratio
	A compressed file format for digital cameras in which the images are
Exif/JPEG	compressed using the baseline JPEG standard, described in ISO 12234-2,
	and metadata and thumbnail images are stored using TIFF tags within an
	application segment at the beginning of the JPEG file.
	A numerical value that is inversely proportional to the exposure provided to
exposure index	an image sensor to obtain an image. Images obtained from a camera using a
	range of exposure index values will normally provide a range of image quality
	levels.
file system	The software structure which specifies how the data are logically organized on
	a given storage medium.
folder	An optional sub-structure in a hierarchical storage area that can contain data
	objects.
	A numerical value calculated from the exposure provided at the focal plane of
	an electronic camera to produce specified camera output signal characteristics
ISO speed	using the methods described in the referenced standard. The ISO speed
	should correlate with the highest exposure index value that provides peak
	image quality for normal scenes.
JPEG	Joint Photographic Experts Group. An image compression method defined in
	ISO/IEC 10918-1.
memory card	A specific type of memory module with a physical form factor approximating
	that of a credit card in outline; approx. 85 mm x 55 mm.
OSD	On Screen Display
PC	Personal Computer. Any personal computing device, which may employ
	various hardware architectures and operating systems.
protocol	Defined mechanisms for exchanging data between devices.
	A device-specific four byte unsigned integer (UINT32) that represents a unique
StorageID	storage area that may contain data objects. The most significant sixteen bits
	of a StorageID represents the PhysicalStorageID, while the least significant
	sixteen bits of a StorageID represents the LogicalStorageID.
USB	Universal serial bus, a digital interface for connecting up to 64 devices in a
	tiered-star topology. See http://www.usb.org.
	The adjustment of electronic still picture color channel gains or image
white balance	processing so that radiation with relative spectral power distribution equal to
	that of the scene illumination source is rendered as a visual neutral.
