Photo autfocus issue

[mmib]

Raspberry Pi Zero 2 W Rev 1.0
Board Revision 902120
Kernel Version 6.6.62+rpt-rpi-v8 
Debian GNU/Linux 12 (bookworm) - Version 12.9

Arducam imx519 camera with focus.

Focus works fine on video however whatever i do I cannot get it work with photos. All photos are taken with LensPosition 1.0 (1.0 m), tried all possible focus handling combinations - it is ignored for photo but works fine for video

Hi, thanks for this post.
I tried to reproduce this with a Camera Module 3 (imx708) but I did not see the described behavior:

1. Configure fucus settings with Window:

2. Trigger Autofocus:

3. Take photo:

4. Select different Autofocus Window:

5. Trigger Autofocus:

6. Take Photo:

Could you please describe in more detail the steps which lead to your result?

Thanks

Hi, thank you for reply. Repeated same steps, here is what i get (photo on screen is the old one):Error in Camera.takeImage: Phototaking caused error: Control AeEnable is not advertised by libcamera

Server needs to be restarted after any error, otherwise there is no video stream. If would be good to implement some try-catch.

Hi,
AeEnable refers to automatic exposure (see picamera2_manual.pdf, p. 79)
This control parameter does not seem to be supported by your camera. That's what the error message sais.
Up to now, I assume that all control parameters documented in the picamera2_manual.pdf are valid, except

• AfMode and all autofocus-related parameters
• AeFlickerMode
• HdrMode

For the latter, I check whether these parameters are available in the Picamera2.camera_controls structure.
This assumption applies to all original RaspberryPi cameras.
Probably, I would need to check for AeEnable too.

If you have activated any AutoExposure settings, you may try deactivating these.

However, this error is not related to focus handling.

I know,
and I tried already to catch as much as I can.
But several of these errors occur in asynchronous threads started by Picamera and lower laying routines, which makes it difficult.

Yes, could be due to arducam imx519, which may not be fully supported by libcamera2. Thank you!
