| A camera incorporating an image sensor which outputs a digital | |
digital still camera (DSC) | 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. | |
|
| |
dynamic range | cf. ISO DSC dynamic range, colour gamut, luminance ratio. | |
|
| |
| A compressed file format for digital cameras in which the images | |
Exif/JPEG | are compressed using the baseline JPEG standard, described in | |
ISO | ||
| using TIFF tags within an application segment at the beginning | |
| of the JPEG file. | |
|
| |
| A numerical value that is inversely proportional to the exposure | |
exposure index | 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. | |
|
| |
| A numerical value calculated from the exposure provided at the | |
| focal plane of an electronic camera to produce specified camera | |
ISO speed | 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. | |
|
| |
JPEG | Joint Photographic Experts Group. An image compression | |
method defined in ISO/IEC | ||
| ||
|
| |
protocol | Defined mechanisms for exchanging data between devices. | |
|
| |
| A | |
StorageID | 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. | |
|
| |
USB | Universal serial bus, a digital interface for connecting up to 64 | |
devices in a | ||
| ||
|
| |
| The adjustment of electronic still picture color channel gains or | |
white balance | image processing so that radiation with relative spectral power | |
distribution equal to that of the scene illumination source is | ||
| ||
| rendered as a visual neutral. | |
