Hello, I’m using the AMS OSRAM Mira220 mono PiVariety camera on Raspberry Pi 5,
and after following the official install instructions:
https://docs.arducam.com/Raspberry-Pi-Camera/Pivariety-Camera/AMS-OSRAM/
, I still can’t find the arducam-pivariety.json IPA file.

[127:59:34.849236002] [390141] ERROR IPAProxy ipa_proxy.cpp:171 Configuration file ‘arducam-pivariety.json’ not found for IPA module ‘rpi/pisp’

Could you please provide a copy of it or the correct way to install it manually?

Hi,
The camera module’s calibration parameters(JSON file) are permanently stored in the MCU firmware on the camera board.

5

Thank you for the clarification. That makes sense. However, I’m still wondering why the exposure settings (such as analogue gain and exposure time) are not being applied as expected on my current device. Could this be a limitation of the current firmware, or is there a specific way to enable full manual control?

6

@Dion
Thank you as always for your thoughtful and detailed responses.
I would appreciate it if you could reply to my question when you have time.

7

Hi,

I cannot understand it. Do you mean you cannot apply exposure settings to what it should be in the output that the command v4l2-ctl -l shows?

8

Thank you for your reply.
Here is what I tried:

I used a command like the following:

libcamera-still -t 1000 --shutter 10000 --gain 4.0 -o test.jpg

(or alternatively, I used Picamera2 for capturing.)

However, with this kind of command, analogue gain does not seem to be applied correctly.

When I run this command, I see a preview log like this for about one second:

#1 (30.00 fps) exp 9996.00 ag 0.01 dg 4.00

After that, the photo is captured.

When I check the resulting test.jpg using exiftool, the metadata shows:

Exposure Time                   : 1/100
ISO                             : 4

I believe this ISO value is clearly too low and incorrect.

Although I explicitly set the analogue gain, the preview log shows analogue gain as 0.01 and digital gain as 4.00. With such settings, it becomes impossible to capture usable images in low-light conditions.

Could you please advise on this behavior?

9

@Dion
Hello! If I’m not using the camera in the correct way, I’d really appreciate it if you could let me know :slight_smile:

10

Hi,
You can try the following command:

libcamera-still -t 500 --shutter 10000 --analoggain 4.0 -o test_ag.jpg --nopreview
exiftool test_ag.jpg
11

@Dion
Thank you for your reply.
I actually tried the same code, and also tested it with Picamera2, but the analogue gain doesn’t change.
(For your reference, I’m using Picamera2 in my actual implementation.)

12

@Dion

Here are the actual results from my tests.
The analogue gain remains at 0.01, and the ISO value is shown as 4.

Hi @ksumiya,
After reviewing the sensor datasheet, we found that this camera doesn’t support gain control. That’s why the ISP remains unchanged, whatever gain value you set.
Sorry for the misleading information in my previous reply.
If you want to capture pictures in low-light conditions, please check the following items:

14

@Dion
Thank you for letting me know. I see — I didn’t realize that some cameras don’t support gain control. That explains the behavior. I also appreciate the link you provided.

However, I’m unable to access the page from my location (I’m accessing it from Japan). The message I get is:

“Sorry, you have been blocked. You are unable to access uctronics.com.”

As for my use case, I’m looking for a camera module that meets the following requirements:
• Capable of capturing clouds at night
• Monochrome image sensor
• Without an IR filter
• Compatible with Raspberry Pi

Does Arducam offer any camera module that meets these conditions?

15

Hi @ksumiya
Thank you for the update.
It will narrow down the options if you want monochrome image features.
We have lots of camera modules designed for low-light conditions. However, most of them have a color image sensor. If you don’t mind this, you can refer to the link below:
https://www.arducam.com/arducam-2mp-ultra-low-light-starvis-imx462-motorized-ir-cut-camera-for-raspberry-pi.html
This camera will switch the IR-cut status according to the light condition.
