Re: Is this RPi 'mini camera' official?

No, that board has no involvement with either Raspberry Pi Foundation or Trading. A third party has obtained a supply of Omnivision OV5647 camera modules (went end-of-life about June 2014) and made a compatible device. The likelihood is that if that third party has done a decent job in the cloning ...

What happens when you hold your phones' camera in front of the peephole? If you get a workable image the camera module will work as well.

Re: New 8MP Camera - Q&A thread

Very simple, I made a hole in a rear lens cap and glued a pvc sewer pipe end cap to it. In this cap I drilled a hole large enough for the sensor (without lens) to peek through and glued four nuts to it on the inside with 2mm holes right above them. Then I used four 2mm bolts with springs around them...

Re: New 8MP Camera - Q&A thread

OK, thanks. I stopped using the camera V1 (and basically the Pi altogether) because of this issue. Glad to see you've been working on it. The nice thing of the camera board when using it with lenses for 35mm cameras is that it has a 'cropfactor' of 10 so a simple 50mm lens becomes an equivalent 500m...

Re: New 8MP Camera - Q&A thread

The original Pi camera had a 'problem' when using it with another lens. I experimented a lot with Nikon lenses but always got a magenta circle in the frame. This was apparently caused by either the lens shading algorithm (without a vignetting lens this caused corners to be colored) and / or micro pr...

I think you need to use '-ex night' for the longest automatic exposure. Up to 2 seconds IIRC.

Re: Is there still something auto even with fixed awbg, iso,

OK. Still if it's important (as it seems to be) you might want to check while the lighting is provided with old fashioned light bulbs that have a glowing wolfram thread. Those will cause absolutely no flicker as the glow will not visually diminish in the time between cycles. Maybe you have some lyin...

Re: Is there still something auto even with fixed awbg, iso,

Is the lighting really constant and not flickering at all? You seem to have a very high shutter speed so if there's any trace of flickering in the lighting it would show up between shots. Most known example is when using fluorescent tubes with shutter speeds higher than the net frequency but I've al...

The sensor will generate a little heat with each exposure, the longer the exposure the more heat.

Somehow a regular Pi Camera module has been made without the IR filter.

Note the original images the black socks become white. White balance doesn't

They have a different chipset. My guess is the Adafruit one is more sturdy though more expensive, especially out of the US where the Adafruit prices are really ridiculous when postage is included.

The lens housing is fixed to the pcb with a sticky pad. Press the housing and it move a bit. If that has anything to do with it then perhaps fixing the housing to the PCB with epoxy would cure it. The sensor/lens package is fixed with a sticky pad so that doesn't change anything. OP, you obviously ...
