A camera incorporating an image sensor which outputs a digital signal
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.
cf. ISO DSC dynamic range, colour gamut, luminance ratio
A compressed file format for digital cameras in which the images are
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 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.
The software structure which specifies how the data are logically organized on
a given storage medium.
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
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.
Joint Photographic Experts Group. An image compression method defined in
ISO/IEC 10918-1.
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.
Personal Computer. Any personal computing device, which may employ various
hardware architectures and operating systems.
Defined mechanisms for exchanging data between devices.
A device-specific four byte unsigned integer (UINT32) that represents a unique
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
tiered-star topology. See http://www.usb.org.
The adjustment of electronic still picture color channel gains or image
processing so that radiation with relative spectral power distribution equal to
that of the scene illumination source is rendered as a visual neutral.
