Get sharpness info from Jetson ISP

Hi all,

I’m trying to implement an Auto Focus function for my project and I want to make this auto focus process as fast as possible. I’m wondering what is the fast way to get the sharpness info of an image? Is it possible to get the sharpness from the Jetson ISP? I’m using both TX2 and Xavier NX.

Please advise. Thanks!

Try below API. (Argus::Ext::IBayerSharpnessMap::getSharpnessValues)

Thanks for the info! I will give it a try.

Thanks for pointing it out! It works great.

Two follow up questions: Is this sharpness info is calculated before all the ISP processes? How do I change the bin size? I’m testing using IMX219 with the default driver. Thanks!
