(JPEG) The original name of the COMmittee that designed the standard imageCOMpressionalgorithm. JPEG is designed for COMpressing either full-colour or grey-scaledigital 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. Start . Filename extension: .jpg, .jpeg. See also PJPEG. (2000-09-11)
