YUV (YUV Encoded Image File)
The YUV Raster image file format
The file extension YUV is assigned to images stored in this special format. Thanks to the splitting up of color information, YUV files can store these kind of information a lot more accurate than images that are stored with RGB. In general, images that have been encoded using YCbCr are referred to by the term YUV.
Technical details of YUV files
The color inside YUV images is split across different components. Matching the file extension name, they are named Y, U and V respectively. Brightness information are stored as Y, while U and V contain the color information. YUV files can be encoded in a variety of bit ranges, namely 12, 16 or 24 bits.
