Enumeration Type Documentation
GBR to YCbCr conversion
Matrix coefficient (typical value) for SMPTE 293M
- Y = 0.299 * R + 0.587 * G + 0.114 * B
- Cb = -0.169 * R - 0.331 * G + 0.500 * B
- Cr = 0.500 * R - 0.419 * G - 0.081 * B
- Note:
- Coefficient values are represented in 11-bit two's complement integer
- DEFINITION = int(COEF * 256 + 0.5)
