Joint Photographic Experts Group definition image, body, file format, standard
(JPEG) The original name of the committee that designed the standard image compression algorithm
. JPEG is designed for compressing either full-colour or grey-scale digital
images of "natural", real-world scenes. It does not work so well on non-realistic images, such as cartoons or line drawings. JPEG does not handle compression of black-and-white (1 bit-per-pixel) images or moving pictures
. Standards for compressing those types of images are being worked on by other committees, named JBIG
(http://jpeg.org/). Filename extension
: .jpg, .jpeg.
