Enumeration Type Documentation

enum vdc5_colcnv_rgb_ycbcr_t

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)
