Hi All,
Can we adjust LCD Panel contrast, brightness, and gamma?
If yes, where can we adjust contrast value?
Thanks,
Best Regards,
Yao
Hi YaoLin
this may be performed by IPU CSC Image Converter (IC) color conversion,
using formula
Y’=Y*k + b
Cb’= (Cb-128)*k+128 = k*cb+128(1-k)
Cr’= (Cr-128)*k+128 = k*Cr+128(1-k)
k represents the contrast factor while b represent the brightness level
examples can be found in
ipu-examples release notes - v0.1
In ips_csc.c, ..SDK\sdk\drivers\ipu\test\ips_csc.c i.MX 6Series Platform SDK
Best regards
igor
