QR code detection

HI

I have one question about QRcode detectenion.
I need fast detection but on high resolution FHD and more becaous QR code is small 8x8mm.

Can I set detect area on screen? because detect on all screen pixels is to slow.

It is possible?

thank you

Take a look at sensor.set_windowing: sensor — camera sensor — MicroPython 1.13 documentation

Oh, and depending on your application, you might want to consider a different lens (perhaps a telephoto?) that will make your QR code fill more of the sensor. Look for one with a “M12” base.
