It appears that ArduCam 64MP contrary to 16MP (which is imx519 based, and natively supported by Rapsberry PI) does not have automatic exposure control.
Both of those problem appears to be missing implementation of camera helper:
- completely (for auto-focus, auto exposure) for 64MP (no cam_helper for the arducam 64MP sensor)
Secondly the patches to support 64MP are missing from ArduCAM/Arducam-Pivariety-V4L2-Driver GitHub repository:
- no recent patch for 0.0.8 of
libcamera-apps
Release libcamera-apps · ArduCAM/Arducam-Pivariety-V4L2-Driver · GitHub which adds--continuous-focus
- no recent patch for 0.0.8 of
libcamera
Release libcamera · ArduCAM/Arducam-Pivariety-V4L2-Driver · GitHub which implementsAfTrigger
and moves thelibcamera::controls::draft::AfTrigger
(prior to 0.0.8) tolibcamera::controls::AfTrigger
- no source code for kernel modules for arducam_64MP, only precompiled blobs
ArduCAM can you share the above source code?
