AM62A7: Inquiry about relevant parameters of LSC

Hi Peng Qiang,

The expert in this topic is currently out of office. Expect an answer this Friday or early next week. 

Thank you for understanding.

Hi Qeng Qiang,

Are you aware of this FAQ: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1405138/faq-tda4vm-how-to-create-lens-shading-correction-lut-for-vpac-viss-lsc?

I suppose you can use the Matlab code provided in this FAQ to generate the LUT and modify the xml file. The Q value is an input parameter to the Matlab function.

Regards,

Jianzhong

This FAQ not the answer I wanted.

What should I do to set the LSC gain to less than 1?

Hi Peng Qiang,

I'll have to defer to Gang Hua for answer. He was out in the past few weeks. Please expect an answer later this week.

Thanks for your patience.

Hi Peng,

We don't normally use LSC gains (or any other pipeline gains) that are less than 1.0x as that may cause false color.

Do the other formats AM62A support? If supported, how should it be configured?

LSC gain format is included in the VPAC-RAWFE-LSC section of AM62A TRM.

Hi Gang

May I ask if AM62A supports gain less than 1? If so, how should I set it specifically?
