TDA4VH-Q1: DPC calibration

Taylar Huang

Part Number: TDA4VH-Q1

Dear TI experts,

According to DPC plugin guide saying "DPC input raw image may be captured directly from image sensor with WDR companding".

I have two questions as below:

(1) Which chart or scene we should take raw image for DPC calibration?

(2) How to make image sensor take raw image with "WDR companding"?

Thanks

Hi Taylar,

There is no specific requirements on chart or scene by ITT (tuning tool).
It is only for you to look at the bad pixels.
You may experiment and decide for your sensor and application.

If your sensor works in WDR companding mode, your captured raw images shall be in that format.

Hi GangHua,

For (1)

Could you describe "specific requirements on chart or scene by ITT (tuning tool)" in detail?

For (2)

Please tell me how to control the sensor work in WDR companding mode? By sensor driver or tuning parameter?

My typo above -- I mean no specific requirements.

Sensor settings are controlled by sensor driver.
