Exif: Difference between revisions

'''Exchangeable image file format''' (officially '''Exif''', according to JEIDA/JEITA/CIPA specifications) is a standard that specifies [[file format|formats]] for [[image]]s, [[sound]], and ancillary tags used by [[digital camera]]s (including [[smartphone]]s), [[Image scanner|scanners]] and other systems handling image and sound files recorded by digital cameras. The specification uses the following existing encoding formats with the addition of specific [[Metadata (computing)|metadata]] tags: [[JPEG]] lossy coding for compressed image files, [[Tagged Image File Format|TIFF]] Rev. 6.0 ([[RGB color model|RGB]] or [[YCbCr]]) for uncompressed image files, and [[Resource Interchange File Format|RIFF]] [[WAV]] for audio files (linear [[Pulse-code modulation|PCM]] or ITU-T [[G.711]] μ-law PCM for uncompressed audio data, and [[Interactive Multimedia Association|IMA]]-[[ADPCM]] for compressed audio data).<ref>{{cite web |url=http://www.cipa.jp/std/documents/e/DC-008-2012_E.pdf |title=Standard of the Camera & Imaging Products Association, CIPA DC-008-Translation-2012, Exchangeable image file format for digital still cameras: Exif Version 2.3 |access-date=2014-04-08 }}</ref> It does not support [[JPEG 2000]] or [[GIF]] encoded images don't use all this.
