Definition: A standard developed by JPEG for reduction in the amount of data required to represent an image and therefore the hard disk space needed to store it. The techniques involved in compression may result in loss of actual data, which may result in irregular rasterization of an image or granularity. JPEG compression is defined only for still-image compression, although a number of variants referred to as "motion JPEG" are used in digital videography.
