YUV - YUV Encoded Image File
Also denoted as a Y’UV file, this is an image storage format which splits the data storage into separate components. The Y, otherwise known as the brightness or luminance is one value while the U and V values, also known as the color or chrominance is stored as a second value. This format stores color information more accurate than the direct RGB information which adheres more closely to the original quality of the image. Not supported by many low end graphics programs.
