Hi,

Is there a LTM hardware module in the ISP?

Where can I find documentation on how to configure it from Vision SDK?

Thank you.

Ionut.

Hi Ionut,

Please check if you can find info about tone mapping in chapter "7.3.3.2 ISS ISP GLBCE Functional Description" of the TDA3x's TRM.

But I think VisionSDK do not support it:
e2e.ti.com/.../2166502

Yordan

Vision SDK supports GLBCE. You can look at the OV10640 sensor as example. There are some default parameters defined as glbceCfg_ov10640 glbceFwbPerCfg_ov10640 and glbceRevPerCfg_ov10640. Please let us know if you need more details.

Hi,

Thank you for your response.
I found tda2xx\src\alg_plugins\iss_aewb1\src\dcc_defaults.h the gIssDccDefGlbceCfg structure with default values.
Where can I find documentation on how to configure this structure?
Can you please share me a document?

Thank you,
Ionut.

Hi Ionut,

the structure vpsissGlbceConfig_t is defined in:
<VisionSDK>/ti_components/drivers/pdk_01_08_00_16/packages/ti/drv/vps/include/iss/vps_cfgglbce.h
and in this header file there are comments for each of it's fields.

Can you check if that can help you?

Regards,
Yordan
