Struct rk3399_pac::isp::img_eff_tint::ImgEffTintSpec

pub struct ImgEffTintSpec;

Chrominance increment values of a tint (used for sepia effect)

Note: Calculation process of incr_cr and incr_cb:

tint values given in RGB format: R G B

converted to Cb and Cr: Cb = -0.148R - 0.291G + 0.439B + 128 Cr = 0.439R -

0.368G - 0.071B + 128

calculating of the increments inc_Cb = (128 – Cb)/110 inc_Cr = (128 – Cr)/110

register entry of the increments with an accuracy of 1/64 incr_cb = inc_Cb * 64

incr_cr = inc_Cr * 64

You can read this register and get img_eff_tint::R. You can reset, write, write_with_zero this register using img_eff_tint::W. You can also modify this register. See API.
