JPEG
An
acronym for the name of the committee, Joint Photographic Experts
Group, that created the standard of image coding standard.
Nearly every digital camera can save images in the JPEG format, which
supports 8 bits per color (red, green, blue) for a 24-bit total,
producing relatively small files. When not too great, the compression
does not noticeably detract from the image's quality, but JPEG files
suffer generational degradation when repeatedly edited and saved.
Video images may be better stored in a lossless non-JPEG format
if they will be re-edited, or if small "artifacts"
(blemishes caused by the JPEG's compression algorithm) are
unacceptable. The JPEG format also is used as the image compression
algorithm in many Adobe
PDF
files.
