Other Parts Discussed in Thread: DM385

To whom it may concern,

We’re using DM385 IPNC Solution but it seems that DM385 Auto Focus feature is not working.

Value being read from Auto Focus fuction changes regardless of actual Focus.

First, in issdrv_alg2AApi.c, what is read from pObj->AFValue = ALG_afRun((Void*)(pObj->fullH3ABufAddr + pObj->h3aBufSize)); of IssAlg_captTsk2A function, appears to interwork with brightness of images.

And it’s suspected that value read through IssAlg_capt2AGetFocus funcion is value that is Not related to changes of image.

In conclusion, DM385 Auto Focus feature is not working.

Thank you for your time in advance and I’ll wait for your informative reponse.

As I remember , AF is not supported by IPNCRDK SW. But there is an application note talking about it.

Thank you for answer.
We've got DM385 IPNC Solution. It was included document, IPNC_RDK_AF_Merit_Fxn.pdf.
The document has explanation about Auto Focus.

Actually, Auto Focus function exists in ISS Source. I think Inner factor's setting is also right too.
There is no content that Auto Focus is not worked.

I want to know why it is not worked.
Please reply again.
