DM368 doesn't support H3A block in its VPSS?

hello everyon!

I find that the DM368 doesn't support H3A block in its VPSS, so if I want to interface the DM368 to RAW data(that means a CCD/CMOS sensor),how can I control the auto exposure and the auto white balance? Does TI supply a library or method to do this?

btw:Does the TI 2A lib in DM365 support 1080P resolution?How can I get the 2A lib?

Thank you very much!Any help will be appreciated!

    As suggested by the note in the DM368 datasheet, TI does not broadly provide documentation and support for this feature. TI does not provide a library to perform H3A functions on both the DM365 and DM368, but we do suggest working with a third party such as Appro, who offers reference designs using CMOS sensors as seen here for both chips.

    Hi,

    Just to add to Bernie's comments, please contact your local TI sales to get information on the possible solutions of AE/AWB algorithms from TI. We might be able to provide some solutions based on the exact use case requirement. Ofcourse third parties like Appro have 3A solutions that can be used on DM365 or DM368.

    Hi,

    RidgeRun is offering a AEW/AE algorithms for DM36x as an standalone C library, implementing different algorithms that can be tuned for specific requirements. You can contact RidgeRun to get the documentation about the APIs. The C library can be integrated with an open-source program called ipiped that allows to control the camera settings thru DBus on Linux systems.

    For more information see:

    Hi Anshuman,

    We have contacted our local Ti rep in Sydney, and been advised to go to this forum - BTB.

    It seems that we are now 'locked' in regards to your reference above "contact your local TI sales to get information on the possible solutions of AE/AWB algorithms from TI. We might be able to provide some solutions based on the exact use case requirement"

    Are you able to assist us directly, or alternatively point us to these algorithms or documentation?

    We doubt that our client will openly accept a royalty situation for the feature.

    Thanks - Peter
