Jpeg, standing for Joint Photographic Experts Group, is one of the best known digital image formats. It was developed in order to standardize the techniques for digital image compression and is used in the internet and on digital cameras. The earliest images which use the JPEG compression method are a set of 4 test images used by the Jpeg Group called ‘Boats’, ‘Barbara’,
‘Toys’, and ‘Zelda’, created on 18th June 1987 in Copenhagen, Denmark.

The International Organization for
Standardization (ISO) and the International Electrotechnical Commission (IEC) received an Emmy award on 2 October 1996 for their work on the standardisation of the Jpeg image format and the Mpeg-1 and Mpeg-2 video formats.
