YUV

YUV is the European television system using a color coding method ( PAL ), PAL and SECAM analog color TV system uses color space. In the modern color television system, usually with three tubular color camera or CCD camera to take the image color, then the color image signal through separation, respectively magnified after correction of RGB, through the matrix circuit is the luminance signal Y and the two color difference signals RY (U ), (V ), BY finally, the sending end luminance and color difference of three signals are encoded separately, with the same channel to send out. The color representation is called YUV color space representation. Using YUV color space is the importance of its luminance signal and chrominance signal, Y U V is the separation of.
