TDA4VM: OX03c10 raw12

Hi Kong,

Sorry, which properties do you mean here? ISP properties? 

Regards,

Brijesh

yes.      I set ISP  but color is not ok 

ok, are you looking for tuning ISP for this sensor? 

Regards,

Brijesh

yes  I  use ox03c10 sensor  and  linear mode ,  but I see img is dark yellow

Hi Kong,

It looks like you need to work on X3C with a provided sensor driver.
Please check with your sensor driver provider and sensor vendor the X3C sensor and driver basics and specific settings therein first.
Without some basic sensor/driver information, we don't be able to set up the property file correctly.

You would need to fill in the property file according to your sensor driver settings.

2. WDR_BIT_DEPTH: 一般是20 or 24 应该怎么选择？
3. WDR_KNEE_X/WDR_KNEE_Y的定义及怎么填写？

It depends on if your sensor works in linear mode or WDR mode.
As X3C is a WDR sensor, it should be in WDR mode typically.
Please check with your sensor driver developer and sensor vendor for the WDR companding knee points in use.

KONG XIANGXU said:

4. BLACK_PRE/BLACK_POST的定义及怎么填写？

This is also decided by sensor driver.
Please check the pedestal value set in your sensor driver.
We would typically measure it in tuning tool to confirm.
For OVT WDR sensors including X3C, it is typically BLACK_POST.

KONG XIANGXU said:

5. H3A_INPUT_LSB的定义及怎么填写？

This is for setting up H3A input for AE and AWB.
Customers typically choose a value around 2~6 depending on the applications and AE/AWB performance.
You may start with 4 initially before AE setup and field testing.

KONG XIANGXU said:

1. 根据文档描述，定焦摄像头不需要多余的H3A步骤，请问AWB及AE也不需要调试吗？

AE/AWB in TI SDK is for reference and demo (not production ready and only tested in lab conditions).
You may set them up and tune in your lab to check the performance and then decide if you would need an imaging 3rd party to provide production-ready AE/AWB.

You may check the links below for setting up AE.

RGGB in this context means Bayer pattern which can be BGGR as well.

Tuning is application dependent and subjective in many cases.
You may start with the default settings from python script and then adjust once you see some changes are needed.

Please follow the plugin guides under the help menu of tuning tool carefully if you have no prior sensor/ISP tuning experience.
If you cannot tell the difference in image quality yet, start with default values from python script and tuning tool first.

AWB
1. 如果图像采用压缩型宽动态范围（WDR）格式，需要一个分段线性（PWL）拐点文件，如何获得PWL文件？
2. Choose Flash Setting/Max Horizontal Paxels/Max Vertical Paxels/WDR Gamma % in RAWFE (100*G)的定义及怎么填写？

Those are described in the plugin guides under the help menu of tuning tool.

A PWL knee point file or PWL LUT file may be needed in some plugins.
Please follow the plugin guide carefully as it may vary from place to place.

The "Gamma %" value is the same as the "GAMMA_PRE".
Please make sure you use the same value in all tuning tool plugins to be consistent.

KONG XIANGXU said:

Color Correction
1. 如何获得伽马对比度查找表？

It is optional.
If you don't know what you want to do or choose yet, you may ignore it and use the default.

KONG XIANGXU said:

EE
1. 从文档中不太理解边缘增强的三块区域具体应该怎么调试，需要此模块调试的具体讲解

EE tuning may be mostly subjective for checking the output image while you change the parameters in the GUI.
Please follow the VPAC-VISS-EE section and plugin tuning guide first.
We will check if there is some FAQ available.

DPC
1. 缺陷像素校正参数如何修改？

It typically depends on your tuning purpose and if there are a lot of bad pixels in certain sensor and lighting conditions.
Please take a look at the VPAC-VISS-DPC section in TDA4 TRM first.

Hi Kong,

Your questions overlap with the below thread which you may check for some of the discussion and answers.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1455891/tda4vm-summary-of-problems-encountered-during-the-first-tuning-of-isp/5717227?tisearch=e2e-sitesearch&keymatch=%2520user%253A629991#5717227

Is this for the same project?
