Re: High Quality Camera RAW Examples

I think you are not shifting the bits correctly. For the first two you would need to move them by 4 bits to the left and for the last one 4 bits to the right?

Could you try "-ag 1 -dg 1" instead of setting the iso?

Re: AWB gains and analog/digital gains changes even though they shouldn't?

I think in principle your third try should work. However, you need to remove the ISO tag, this contradicts the ag/dg/ss values and raspistill will change the values. Additionally, the value of dg needs to be in the range 1.0 to 64.0, your value of 0.5 is invalid. Could you just try: raspistill -o te...

Re: rpi-update stops HQ Camera working

For rpi-update you can add the commit ID from the firmware repository to go back to a specific firmware version. I updated my firmware some days ago(commit 32f9280), which worked fine for my Pi4 and HQ Cam. You can try something like sudo rpi-update 32f9280 to go to a previous version. rpi-update al...

Re: Has something changed with Raspistill ?

I think it is the other way around. The roi specifies the area of the image which should be put into the output image, the w/h is just a scaling this to the selected image dimensions. In you case -w 200 -h 150 would take the whole image and scale it down to 200x150 px. The other case "-w 400 -h...

Re: Camera v2.1 blurry after going from PI 3 to PI 4

The plastic holding the lens is also quite soft, if you have some pressure on the side on this from your case, this will result in some tilt and shift on the lens, which create a Scheimpflug effect type of image, where different areas of the picture will be out of focus. Make sure that there is no p...

Ok. Then just remove the -ex off and set ag dg and ss. These are the freedoms the auto exposure algorithm will change, if they are fixes the algorithm basically can't do anything.

On my notebook it will easily get about 800MB/s read/write when connected to USB3.1 and about 350MB/s using USB3.0. The general speed of the device should be just fine. I will try a powered hub tomorrow or so, to see if the power consumption is a problem.

You even get 24bit, 8bit for each R,G and B value. :lol:
But if you want to get 12bit for each, you are out of luck, or at least it is very unlikely(at least for h264 or mjpeg).
