-
Where did you get the camera module(s)?
Arducam
-
Model number of the product(s)?
arducam_64mp
-
What hardware/platform were you working on?
Pi Zero 2W
OS was Astroberry, but it’s been updated to or from buster for the camera support to work.
-
Instructions you have followed. (link/manual/etc.)
Manual
-
Problems you were having?
Using the shutter option the captures take ~10x as long as the shutter time. In one recorded with --shutter 10000000 (10,000,000) below it takes 119 seconds.
-
The dmesg log from your hardware?
Will capture if requested. (Pi isn’t on normally.)
-
Troubleshooting attempts you’ve made?
Varying the shutter time, this is the same at 1 sec, and 100 sec (Didn’t record time on that one, but subjectively, yeah. I kinda even dozed off after about 10 minutes, while waiting, and the notification bell (from monitoring for activity) woke me up, but I didn’t record the time.)
Various attempts over various options (ex: --timelapse was tried in the example below but didn’t seem to work? others include -n (nopreview) -r (raw) -k (keyboard) -s (signal)) and several others. Nothing seemed to change it, there also didn’t seem to much cpu use until the end (Could be encoding?), like it was waiting for something, but the length seemed tied to the shutter speed, so I don’t think it’s a keypress via -k or anything like that.)
EXIF data a when jpegs were captured showed the shutter value as the requested value. (+/- as they usually are, like 0.998… for 1sec.)
- What help do you need?
Looking at fixing it. I got this for among other reasons an all-sky camera (or rather a much-sky camera), and the images are good so far. Just I’d prefer more than 10% of the time being spent in capture.
I’m planning to write either a modify a driver if needed or write a new one to have this supported in INDI (telescope control software) later as well, but this kinda hampers baseline understanding.

pi@astroberry-one:~ $
Using another pi, in this case a ‘Raspberry Pi 2 Model B Rev 1.1’ I find the following, raw log below:
Shutter time (microseconds/seconds) - Clock Time (seconds) (* in log below) - (Predicted:) 5shutter+10 sec:
1000 - 11 - 5.016
10000 - 12* - 5.16
100000 - 13* - 6.6
1000000 (1sec) - 20* - 21
5000000 (5 sec) - 84 - 85
10000000 (10sec) - 165* - 165
40000000 (40 sec) - 644 - 645
100000000 (100 sec) - 1604* - 1605
So it looks like there’s a base time for setup of ~5 seconds (based on more tests not below of 1000 time), then about a 16x factor based on shutter time.
Above, time is 5-12 sec + 16*shutter time matches within a second for everything over 1 second shutter, and looks pretty linear, aside from the really short ones.
Can anyone else try to confirm this is a problem esp on a pi 4? (I can try an ‘original’ Zero (v1.3 non-W) and a Pi 1 B+? (of some description)

Just to note, this is a completely different (fresh) install, different sd card, even different 64mp camera on the Pi2B.
More testing seems to find a maximum, this was attempting to set 400 sec ( less than the FAQ 435sec as I recall? )

Which amounts to much less time than I expected. Amounting to 3805 seconds, I found it interesting as well, applying in reverse the 16*shutter + 5 = clock time, I get 237.5 sec exposure, and when I look at the exif file (part of exiftool output, rest doesn’t have anything else interesting):

So It looks like is called successfully LibcameraApp::StartCamera(), but that’s the last output until libcamera_still’s
app.StopCamera();
std::cerr << "Still capture image received" << std::endl;
Gets called.
I have other things to do for a while, but if there’s any information needed I’ll see about getting it.
So far haven’t found a resolution to this.
