digital still camera	A camera incorporating an image sensor which outputs a digital signal
(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.
	The ratio of the maximum luminance level that appears unclipped to the
dynamic range	minimum luminance level that can be reproduced with an incremental signal to
	temporal noise ratio of at least 1, as determined according to ISO 15739.
	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 an
exposure index	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.
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.
	Universal serial bus, a digital interface for connecting up to 64 devices in a
USB	tiered-star topology.
	See http://www.usb.org.
	The adjustment of electronic still picture color channel gains or image processing
white balance	so that radiation with relative spectral power distribution equal to that of the
	scene illumination source is rendered as a visual neutral.
