3.2 white balance adjustment YPbPr channel
Input 480I (968 model) signal of VG-848 to YPbPr terminal, input 16 level gray-scale signal, set the
fixed-value of R Gain to 80H, G Gain to 80H and B Gain to 80H for white balance adjust. Adjust
offset_R, offset_G and offset_B, to let color coordinate of the fourth level be 254 and 250 and its
brightness be about 3.5nit.
Input 8 level gray-scale signal of TIME392 (480p), TIME394 (720p) and TIME396 (1080i) separately,
repeat the above operations to let color coordinate of the third level be 285 and 290 and its
brightness be about 12.5nit.
