TDA4AL-Q1: R_adjust(percent) in AWB tuning xml

Taylar Huang

Part Number: TDA4AL-Q1

Tool/software:

Dear TI experts,

We find R_adjust(percent) in AWB tuning xml will be changed while modifying gamma value in AWB calibration UI.

So, this value is related to Gamma value applying. Is it correct?

Yes, it is for passing the pre-compression gamma value to openvx AWB kernel.

Hi Gang Hua,

So, we can't R_adjust for R gain adjust from below. Is it correct? Then can we use B_adjust(percent)?

3500, // low_color_temp_thresh
100, // apply_rgb_adjust
48, // R_adjust(percent)
90, // B_adjust(percent)

Neither of those are usable.

The feature is not supported by AWB.
