electronic still picture camera
camera incorporating an image sensor that outputs an analog or digital signal representing a still picture. andfor records an analog or digital signal representing a still picture on a removable medxim, audi as a memory card or magnetic disc
[ISO 12232, ISO 12233. ISO 15739]

Exit
exchang.abi. Image file format
digital still camera image tile format stanc1d of the Japan Electronic Industry Development Association
(JEIDA)
NOTE The JPEG version of Exit pro’ades a compressed tile format for digilal cameras m wtiich the images are compressed using the baseline JPEG standard descflbed in ISO1IEC 10918-1, and metactata and thumbnail enages are stored uswig TIFF tags within an application segment at the begiming of the file.
2.37
exposure index
numerical value that is inversely proportional to the exposure provided 10 an image sensor to obtain an image
[ISO 1 2232J
NOTE Images obtained from a camera using a range of exposure index values etil normally pronde a range of image Quality levels.
2.38
exposure process
various methods to capture images Wi the electronic still picture camera
2.38.1
sIngle exposure
acquisition of a picture by a single exposure, with one or more image sensors, that exposes all sensor pixels. all colours, and all image locations at the same time
2.38.2
colour sequential exposure
acquisition of a picture by combining repeated exposures to capture different colour components
NOTE Colour sequential exposure can be by means of three colour illuminations, or by three colour filters
2.38.3
time sequ.ntlal exposure
acquisition of a picture by combining repeated exposures to capture different spatial components
NOTE Time sequential exposui’e can be edh S line array (line scanning) or an area array Wilh a line array, the picture s acquired by opbcal ow physical sub.scanning with an image sensor In one dimension. With an area array, repeated exposures may integral, smaller pictures Into a larger picb,,re by means of Image sensor shifting.
2.39
exposure series
series of images of the same subject taken using different exposure index values.
