34.4.4.2 Color Space Conversion
This module converts YCrCb or YUV pixels to RGB color space. Clipping is performed to ensure that the samples value
do not exceed the allowable range. The conversion matrix is defined below and is fully programmable:
R
C₀ 0 C₁
Y – Y_off
G ^{= C}₀ ^–C₂ ^–C₃ ^{× C}_b ^{– C}_boff
B
C₀ C₄ 0
C_r – C_roff
Example of programmable value to convert YCrCb to RGB:
^{R = 1.164 ⋅ (Y – 16) + 1.596 ⋅ (C}r ^{– 128)}
^{G = 1.164 ⋅ (Y – 16) – 0.813 ⋅ (C}r ^{– 128) – 0.392 ⋅ (C}b ^{– 128)}

^B
=
1.164 ⋅ (Y – 16) + 2.107 ⋅ (C_b – 128)
An example of programmable value to convert from YUV to RGB:
R = Y + 1.596 ⋅ V

^{G = Y – 0.394 ⋅ U – 0.436 ⋅ V}
^{B = Y + 2.032 ⋅ U}
