IMX8MP - image capturing format for ISP Calibration

[jp4]

Hello @joanxie 

Need a clarity on capturing images for ISP Calibration of our own camera with imx662 sensor.

1. As per ISP Calibration Tool Suite User Guide, we need to capture images for each calibration steps in a particular image format. Some steps says raw12 some steps says .bgm .jpeg. So what is the format suits for all the steps and how can we capture images for ISP tuning?

FYI, till now I am using tuning-client tool to capture the images for ISP tuning (output format will be either .raw12 or .yuv). Is this correct or do we have any other way to capture images in a particular format which isp Calibration demands? Also please mention how to capture images in .png/.JPEG format in IMX8MP?

2. Chapter 6 (lens shade correction)says , the test images must be black level corrected, but without any further processing. In my case I am using existing calibration files (ov2775) which is provided in samples folders. So how can I bypass further processing of ISP while capturing images for lens shade correction? 

Basically what calibration XML files should be mentioned in run.sh while capturing images for ISP tuning? Can we capture images without adding any calibration.xml file?

Thanks in advance

@joanxie  kindly consider this in prior. thanks in advance.

How to capture RAW images (bypassing ISP) for ISP tuning.

according to the private message, you can do this using the default calibration files

I'm not sure if I understand your question， the detailed steps were mentioned in the chapter 6.1.1 Setup for raw image capture already
