7.7 YUV output
The AB-800GE has a YUV output, as well as an ordinal RGB interpolated output.
The conversion formula is as follows and cannot be controlled externally.
Y = 0.299*R + 0.587*G + 0.114*B
Cb = 0.5*B – 0.169*R -0.331*G +128
Cr = 0.5*R – 0.419*G – 0.0813*B + 128
While RGB output is 24-bit (8 bits per color), YUV takes advantage of the human visual
system's lower acuity for color variations than for luminance.
The color information (chrominance) is sub-sampled at half the rate of the brightness
component (luminance). Thus, YUV can be compressed into 16-bit output for a faster
full color frame rate that is visually perceived as close to RGB, albeit with lower actual
color precision.
