Hi,all!
Platform: DM368 + Image Tuning Tool
Now I am tuning the RGB2RGB Matrix. But there are somethings I am not clear.
1.In the Tuning Guide, it describes that the black level and the AE should be right. In Image Tuning tool, ColorCorrectionMain Tab, after pressing the AutoTune button, the DC offset should be small, and the G gain is aroud 1.0(i.e., 512).
but I want to know in what range the values are proper ? Now my G gain is 861, and the offset is -1,-23, -28 .Are they proper ?
2.In the Tuning Guide ,it describes that "Matching Gamma Funtion between IPNC and reference camera is important!" .And How can I get the reference camera Gamma Curve ?
and In Image Tuning Tool, "Color Balance | Gamma RAM Table File" Tab,it shows that "Gamma table from server", does it mean that Now the gamma in use is in Ram ? and when tuning ,the Gamma select choise is "From GUI" , what does it mean by "From GUI" ? does it mean the gamma is read back from the IPNC ram ? or ?
3.as describe above , it requires a proper AE. and when I capture the raw data , it looks dim. and I want to know the average brightness of the raw data. How can I get it? and what value is it sopposed to be ?
4.Now I find that when Capturing the raw data,which take a shot of the 24-color checker, the white color has become a little yellowish. Is it the AWB problem or the RGB2RGB matrix problem ?
Any comment will be appreciated !
