Joint Photographic Experts Group
     
         (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} and {MPEG}.
