Dear All,

 

Hello. Refer to "37.4.9.5 Color Space Conversion unit - CSC" in MCIMX6DQRM(Rev.2).

Could you explain below formula?

(I couldn't understand the below formula.)

===========

A more explicit formula:

S[i] = (sum(A[i][j]*In[j]) >> 4) + (B[i] << 2) + (1 << (3-E[i]))

Out[i] = Clip(S[i] >> 4-E[i])

===========

 

Best Regards,

Keita
