TDA4VM: AE How to generate exposure table

Hi Li Liu,

Could you clarify which exposure table you're referring to and what you're attempting to accomplish?
You may check out this thread as it might apply to your question: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1224255/how-to-set-ae-table-about-exposure-time-and-gain-control/4623947?tisearch=e2e-sitesearch&keymatch=exposure%2520table#4623947 

Thank you for your reply

From the documentation, it seems that it only defines the exposure time range setting and gain value range setting for AE exposure.
But there is no indication of whether the priority is to increase gain or exposure time when enhancing brightness
When to use gain to enhance the brightness and when to use exposure time to enhance the brightness
In other words, there are only exposure limits, but not the order

If convenient, can telephone or WeChat communication, tele:17806284836

TI's reference AE prioritizes exposure time first and then gains.
You may refer to AE source code for details "TI_aaa_ae.c".

hi

Thank you for your reply
According to your meaning, we do not need to do exposure table, as long as the simple setting of exposure time and gain threshold, AE will be able to normal exposure

Wanted to make sure I didn't have a problem with my statement above
