when I run 1_test.py I still got the green frame, I don’t know why, and try several times but still green.
Hi,
It is due to we don’t have awb. The image looks green, which will not affect the algorithm calculation
Thank you so much, but how can we add the awb in python to solve, if I want to make it normal.
thank you, I solve the problem
Hi,
Arducam technology team are developing ISP camera which will solve AE AWB and other problems.
Hi zone870426,
may I know how you solve the green frame problem? Mine is still showing green. Thanks a lot!

Hello,
It is due to the image is original raw bayer image without post ISP process. Green channel
account for 50% of the data volume. So the image looks green, It needs ISP to do AWB to compensate R and B channel. At present, we are developing our own ISP. For the raw image, the green is normal.
I have the same problem, I cannot get a normal-color image from the dual cam system (I just bought a B0265R kit).
In these instructions you clearly demonstrate that the images are good, so why can’t we get the same results? where is the problem?
Hi,
In the instructions, we use raspistill tool to test instead of MIPI_Camera. Due the MIPI_Camera driver does not have ISP to process. The image you get without AWB and AE, so the image is green. You can use raspistill to get the normal image.
Feel free to let me know if you need more help.
Hi @Bin, thank you for your answer, but in the instruction you provided on your website you are clearly using the MIPI_Camera driver and arducamstill to get a good colored image in “mode 1” using ./arducamstill -t 0 -m 1.
Is this a documentation error? I am asking because I bought this kit to have something usable almost “out-of-the-box”, and right now I don’t have the resources or competences to develop a new driver/program by myself.
If this is the case, I will have to send the B0265R kit back and find another solution…
Using the standard raspistill software is not an option because it gives an half-resolution shrinked images, while I need a dual full resolution frame.
I also noticed that the latest version of the libarducam_mipicamera.so (from git) lacks the support of Mode1 (8112x3040 resolution), I had to download an older version to have the Mode1 working.
Is there something else I can do or try? Or can you point me to some other resources, or beta driver or something I can use?
Thanks for your support
Hi,
On Raspberrypi Platform, we have software ISP but the result is not very well.
On Jetson Nano Platform, we does not have ISP, so the image is green.
Please attach me your hardware and the image you get. I will help you check it in detail
About lacks the support of Mode1 (8112×3040 resolution), I have fixed the issue today
Hi @bin, thank you again for your support. I was able to do some tests today and this is the results.
I am using a RPI 4B 8Gb, with Raspberry OS 2020-12-02-raspios-buster-armhf.img image installed and kernel 5.4.79-v7l+ #1373 SMP (also tested with older and newer releases), connected with the B0265R kit (Arducam 12MP Synchronized Stereo and 2 imx477 HQ camera)
With the new libarducam_mipicamera.so that you fixed, the problem with the missing Mode1 is resolved.
With the default arducamstill demo I was able to live-view a colored image (after adding a lot of illumination in the room), but the same image saved using:
./arducamstill -t 1000 -m 1 -q 100 -r -e jpg -o test2_green.jpg
was still dark green; I found out that adding more time to the -t option, the image was saved correctly:
./arducamstill -t 2000 -m 1 -q 100 -r -e jpg -o test1_good.jpg
when trying to save in bmp format I get a timeout error:

./arducamstill -t 3000 -m 1 -e bmp -o test3.bmp

using ./capture_raw I get a file named 0x0.raw, but there is no way to open it, even with the python demo programs.
What can I do to obtain a raw or bmp image (or any other high quality file format) ?
Sorry for the long post, hope you can help me solve this problem !
thank you again
PS: If you need them, here you can find the original images and the 0x0.raw file:

Hello,
Thanks for your patience. About the first issue, it is due to the software ISP need time to adjust AWB. So you should preview the image for a while to wait the awb normal.
About the mode1 error in BMP mode, It may be due to the RPI image encoder does not support so big resolution. I will test it when I have time.
Feel free to let me know if you find something new.
Hi again, I did some other tests in daylight, but the results were terrible. The image was very overexposed, I had to close the diaphragm but it is very sensible, and is very difficult to obtain the same exposition on both cameras.
I’ve tryied to manually set the exposure via sw, but I didn’t succeded. It seems that the camera (using arducamstill) doesn’t support the exposure or gain control:

arducam_set_control(camera_instance, V4L2_CID_EXPOSURE, globalParam.exposureVal); arducam_set_control(camera_instance, V4L2_CID_GAIN, globalParam.GainVal);In another post, you said to try using the function arducam_write_sensor_reg but I don't understand how to use it and where to find the registers for the imx477 camera.
if I don’t ask too much, could you provide some working example?
Luca
Hello,
Sorry to hear that, I have add exposure control for imx477. I have update the lib and arducamstill application. Please download the latest lib to try. IN fact if you want to adjust the exposure, Just adjust the 0x0202 and 0x0203 register. If you wan to adjust the gain. Just adjust the 0x0205 register.
Feel free to let me know if you need more help.
Hi, thanks, by changing those registers I was able to do other tests:
I wrote a python program to cycle all the GAIN and EXPOSURE values of the registers and I was able to change the image. However, the image is not yet usable, many other adjustments would be needed to be useful.
Here you can find a video made inside:

as you can see the colors are always greenish. I also tried outside in sunlight, but the image is always overexposed and obviously with wrong colors.
Of course, colors are fine when using raspistill, but the image is compressed into one frame.
At this point I don’t know what else to do
Hello,
Using raspistill, which has ISP post process, so the image we get is great. But the raspistill just support RPI camera 5mp/8mp/12mp. Our MIPI_Camera support all of arducam camera, but without ISP. So the image we get is original image without ISP post process. We can adjust the digital gain and exposure time to fine tuning the image quality manually. If the image is green, you can try to reduce the GR and GB channel. and increase the R and B channel.
Feel free to let me know if you need more help.
How much longer until AWB & AE is ready for the arducam? I too purchased a B265R (after purchasing two B270’s, which apparently aren’t compatible with the stereo hat) and would appreciate the functionality for which we paid for…
The documentation shows AWB and AE functional when using Arducam but currently it doesn’t work.
At least an ETA would be very helpful.
