Sharper than the iPhone!

64 megapixels and autofocus for your Raspberry Pi. Can you really resolve that much detail in such a tiny camera, or is it just marketing?

Love the great info using your knowledge of photography. I always struggle to explain to folks why more MP isn't always better when you're talking about small sensors.

[SeanHodgins]

We need manual focus so it can be controlled with some extra hardware like an encoder.

[Steamrick]

I'm glad you acknowledged the limitations inherent in tiny (and cheap) lens and sensor systems.

I am once again asking people to stop referring to quad-bayer sensors by their sub-pixel resolution instead of filter resolution.

[fredrik]

I think one advantage with this is that for 1080p video you can still punch in with the digital zoom to get a tighter framing without really sacrificing resolution. You should still have 1:1 pixels.

i think it would be pretty interesting to build a small photo-scanning-system with this.
to bad i cant program.

MP doesn't tell at all how good the quality of the image is, in general though the higher the MP the less quality you get, instead you have tons of noise and other artifacts

I was watching this in my university library and it turned out that my headphones were not connected properly so the entire library just hear Jeff Geerling scream "64 Megapixels". Thanks Jeff.

That's really amaizing camera! Great video

[izzieb]

It's a shame the bandwidth of the Pi limits the video ability. The image resolution isn't that important really. Shame it also doesn't have pixel binning, that would help reduce noise at the expense of resolution, which I think would be worthwhile.

Also, the Hawkeye seems to render skin tones differently - seems to have a magenta tint. I'd say the normal Pi camera has nicer skin tones. Not that it's probably meant for portraits anyway.

Great video. A Few camera manufacturers started pushing micro 4/3's sensors with outrageous claims that they could outperform full-frame Nikon and Sony cameras. A few of my friends fell for it before I could reason with them. They could not understand how my Nikon D810 from 2014 could produce a better image, especially in low light than an Olympus from 2022, and cost about the same as my D810 in 2014. The Olympus does have a better pixel pitch (3.36) vs D810 (4.88) but the D810's sensor is 2 times the size .

Oh my this will be amazing for Octolapse timelapses

Finally someone is honest to upgrade an iPhone to its full potential :)

Man!!! This was a hell of a benchmark! Congratulations! Videos like this are something that makes not regret to subscribe your channel. Continue the good work, Jeff. We keep watching, even if you don't answer messages or comments.

I'd love to see you make an inexpensive pi based macro microscope for things like soldering

[davidg]

The banding seems likely due to the CMOS sensor's readout train. The perfect regularity of it suggests the ADCs to me. Try running the Pi off of a battery or a UPS and see if it still gives that banding.
I've seen similar banding with CMOS sensors used for astrophotography and it's frequently resolved by feeding it clean power. Though sometimes it's a temperature issue (astrophotography being an extremely low light endeavor, thermals contribute significantly to electronic noise in the image).

EDIT: It sounds like Arducam confirmed it's the denoise filter at very high resolutions. I guess the easy way to find out is to disable the filter above 16MP and see the result -- I don't have time to test it out myself for a few days, though.

Very good usecase: Focus stacking. The focus motor can be "manually" controlled. It would be easy to write a script that takes pictures at different focus settings and then stacks them together. Disclaimer: I haven't tried it yet. I ordered one of these, but I hope it works.

[IamTheHolypumpkin]

The CM4 has 4 lane CSI-2 hence you can transmit 4k30 video over it.
And the PCIe bus can also barly keep up with 4k30 to allow you to process the video on an FPGA instead of software.

[SarahKchannel]

"good" sensors have something called global shutter, where the sampling of pixels is sort of frozen in time, where normal cameras rely on rolling shutters. A method like scan-line where each row is sequently read. This looks a bit like an interlaced read-out vs. the stroboscopic effect of the lights vs. the camera read-out.

[tokiomitohsaka]

Would have been perfect for a machine vision project I am working on if the sensor had global shutter.
