- Inspired by @raspy00135 I designed this Scanner Camera. I call it Super Cheap Scanner Camera (SCSC).
It is able to take pictures with extreme resolution and good image quality, while being very cheap to make.
Correction: In 2:29 I say that the camera has 48 bits per channel, which is incorrect. What I meant was 48 bit color depth, which is 16 bits per channel. Thank you, @soza.pidgeon for pointing this out.

Very cool! Have you considered using old large format lenses instead of projector lenses? They can have massive image circles, and many can be got for a great price even cheaper than more modern medium format lenses, because they are simpler (they literally just mount on a lens board and are focused by moving the lens itself).
Agreed. They can be found not that expensive if you look for one without shutter. You would have to mess around though with fixed aperture holes since that is usually embedded in the shutter.
For example a rodenstock sironar 150mm is quite good in resolution, most of those have an image circle between 4x5" or 5x7"
Thank you very much for the suggestion. I remember, having considered them, but after the first google search I originally discarded these lenses for being too expensive...
However, there seem to be many used large format lenses for below €100 on eBay. I think this might be the next step towards legit 500mpx :)
IMHO this is the main reason I've considered building a scanner camera.
@@yunuszenichowski Another suggestion: Have you thought about trying an old enlarging lens? An old 135mm Wollensak Rapter or a Schneider Kreuznach Componon 135mm (covering 4 x 5 inches) can be found online for about $35US, and a 210mm Componon (covering 5 x 7 inches) for about $70.
Great work! I've seen a lot of DIY scanner projects over the years but the results have usually been only "interesting", they actually appears to be usable and high quality with yours.
Thank you, I am happy to hear that. Might upload another video with more images, since I now have the required filter to shoot in natural light.
@@yunuszenichowski please, do so!
@@yunuszenichowski please do! I used to take pictures of artwork for a job and this would be a wonderful gift to certain institutions.
Yes, please do. And as soon as you feel like you have the design worked out please post the updated plans. I would love to try my hand with this project.
I love seeing the ingenuity on builds like this. Even though it has some glitches, it still adds to the charm of the wonderful device you've created.
This reminds me of the scanbacks for large format cameras. Nice work!
I'd love to see more about this project in the future
I'm a sucker for odd photo stuff and this is right up my alley
I saw the original video and was fascinated. Now thanks for giving us a more easy way and for the demonstration that the concept actually works. Im not an engineer but will try my own design now.
Nice making Yunus! Thanks for sharing, and good fortune for all your projects.
I am so building one with my friend, thanks for open-sourcing it.
in my opinion this just looks like a way to take high res 80s 90s style images. theyre very beautiful
Congratulations on your engineering skills. Well done.
Interesting project, indeed. I've made a photo of my daughter once - long before I got my first digital camera - by using a black-and-white handscanner on a glass plate. By moving it up or down, I could indeed get a picture, but just as with your system, the object should be stationary (which my daughter tried, but still she appeared a little wobbly 😉). The scanner was connected by a parallel interface and gave dithered results, just to get the idea of the image quality in those days (I think Windows 95)...
Wow. Awesome idea. Now I want to build my own hasselblad xpan like scanner camera.
Very cool idea! Great design
Keep it going! Amazing work
This is amazing for art photography
that is cool. for really cheap lenses that will increase your focal length options look at enlarger lenses. Several come in a ltm mount or m42 mount. really easy to adapt.
I picked up a 135, 105 and 55mm last month for playing with 4x5 film. Didn't spend more than 65 bucks for all three.
Such a smart workaround, I will absolutely try that, thank you :)
Really good idea as those lenses are quite literally made for the purpose of projecting a huge picture! And they come with apertures
Yooo, can't wait to see the progression of this!!
Awesome project!
Awesome concept!
Excellent job!
This sounds like it wold be perfect for taking pictures of negatives
True tbh, you could compact it down as well by removing the lens and just placing the negative directly against the scanner. Wait...
Amazing. Interesting image.
This is amazing.
Awesome! I love it!
This has inspired me so much. How did you add ISO control? Is it with the clock setting? Tricking the white balance to control ISO maybe? I hope you do a follow up or even a quick build guide. Great work man.
It makes me happy to hear that it did inspire you :) The ISO is controlled by regulating the power the scanners LEDs get, which are used for calibration before (and after) each scan, using resistors (effectively regulating their brightness).
@@yunuszenichowski oh wow! That makes sense. If it calibrates the white balance that way then it would also change the sensitivity. So you could alter the ISO and white balance if you used LEDs that changed color and intensity.
Did you make your own led board or cut down the stock one? I’m wondering if I could make a diffused light source with amber and white LEDs.
I just cut down the stock one, but I think it would be very easy to change the LEDs for different ones. It is just connected over 6 power lanes and 1 ground lane with a ribbon cable. However, you could also power your lamp with a different source, since the scanner does not care if the LED is disconnected, it only throws an error, when it is too dark for the calibration.
Also, I diffused the light, like they did in the scanner, using a white piece of paper, which the LED points at rather than at the sensor directly.
@@yunuszenichowski this is very helpful. Thank you. I got the case printed last night I have a scanner on order need to print the gear and other internals on my resin printer next. Thank you for all your hard work. I think I will make a video on this project as well. Show what works and what doesn’t.
Let me warn you, this is not a finished project and I would assume replicating it would take quite some time and experience, mainly because the 3d model is unfinished! You will have to think about cable management, how to integrate the limit switch, etc.
Extremely interesting... thanks for correcting the 48 bits per channel, I was having a heart attack when I heard that. And worst case, you proved once and for all that pixel count is not everything...
10 months later, I watched the video again and i was about to get another heart attack at that "48 bits per channel" lol
This is amazing
Thank you so much :)
Very cool project! Did you have to disable the light that is normally used for regular reflective scanning?
Very cool stuff. How many pixels are the sliver segments of the photos that you were expanding? Are they high enough resolution to be printable? Because I would be printing those. They look really interesting in my opinion.
Nic to see this is still being attempted although it doesn't seem like the problems we had ten years ago have been solved.
wow ingenious design, maybe you can try to replace the projector lenses with maybe canon or nikon lenses for better image quality as those lenses aren't very expensive but can deliver superior photo quality, or maybe make it adapt into a microscope lenses for extreme macro photography, it should be easier to incorporate as it doesn't require any special mounts and is cheap as well. But idk i'm just spit balling on some ideas. But amazing design none the less! This would be amazing for astrophotography! might attempt to make one once the design is finished.
Thank you for the ideas. I am unsure if the camera would be able to capture the dim light of stars. You also can't make long exposure shots with this camera. But I will definitely test that at some point.
@@yunuszenichowski Just need a lens that is large enough. Like a liquid lens.
I'm also definily interested in the possibility of AP with this type of camera, will definitely be needing a star tracker since I'm not sure if this is fast enough to not have distortion from the slower exposure time.
Image stacking might help with the low light and the high res images could be an upside if it doesn't take a ridiculous amount of time to take a bunch of pictures to stack😅
@@Joshplv At a certain focal length, you just need the sensor stick, without the motor. You just let earth rotation do the swipe.
😁
Ooh, I wanna try something like this now!
Mega video! 👍🏻👍🏻👍🏻
Do you think you'd be able to keep the sensor still but make the scanner think it's moving? If you can, you could do fixed-slit photography.
awesome video mane
this should be sold as the album cover camera
Interesting concept
The camera create one crazy vibe and artistic liberty for sure. The style it makes are unique but from the looks of it, quite hard to get a "Decent" imagine imo
I tried the same with epson junk scanner in over ten years ago. but i did not get good image. The image of your camera is very interesting still today. Thanks for your nice work.
Awesome project! You should be able to fix the bokeh to by using a fresnel lens as an collimator!
Amazing
A line scanner camera would have been perfect for indoors design photography and archival photography of painting etc..
Genius👏👏👏
Very cool. It looks like still life images work really well…..thanks. Laurie. NZ. 😊
Sehr geil!
This gives me an idea.
Great work! I interested about if the linear long enough it possible capture photo like the Xpan take the amazing panorama!?
Mega cool.
The castle one goes hard.
i am a simple man. i see forsen, i like the video
You live in Germany... Berlin? This is the first video I watched of yours. Really Good!
Ideal for sport photo....
Impressive, a scanner camera is something I've wanted to do for awhile now, I have been planning building it as a 4x5 back for a film camera. How much is directly pulled from the scanner, is it just the sensor or are the other electronics and movement system from the scanner retained? Looks to be mostly replaced, but it's hard to tell since I've never seen the guts of a v37 before. Standard scanning software or custom?
I essentially just removed the case of the scanner and reorganized all of the parts, required for the operation of the scanner, to fit in the camera form factor. You can look at it in detail in the 3d model.
It uses the standard software.
I wish you great success with your build!
I don't know if you still read comments on this video, but you could drastically improve the contrast of the picture, if you would flock out the inside of your projector lense. They are very reflective but if you would use something like black 3.0 or other light absorber inside the lense, you would stop bouncing light in the lense and improve picture quality.
I was gonna say it's an awesome idea, why aren't there any consumer products like this. Then i remembered that my scanner took almost a minute to scan a picture (it did a double pass or maybe that was the software). And the result was "grainy" as if printed on woven fabric.
But I guess for detailed pictures of art or any other still live, it's pretty cool.
Awesome
I suggest adding some stabilizer system because it is acting like really slow shutter speed ( not from the lens but from the natural movement of the device/wind/earth) or a super steady tripod
The results remind me of Carrivagero paintings the deep contrasts and shadows
Try portrait photos of people .
They'd look amazing like oil paintings
what sbc is controlling the scanner board? rpi? nice work and finally i see a compact and clean version of these kinds of cameras
Thanks for designing a cheaper and easy to fabricate version ^^
Are there more accessible scanners that would be easier to get? I was not able to find any listed for sale locally.
The only requirement for the scanner is to have a CCD sensor, but you would have to adapt the design, when using a very different model. However, I know that the v370 should definitely work. The v30 and v33 look like they have very similar designs as well.
I feel like I should mention this again. The 3d model is not complete and should only be used as inspiration for your own design. The camera is in fact designed quite badly, because I was under pressure to finish the project (there is a lot of double-sided sticky tape involved).
Very cool. I wonder if the movement of the mechanism during capture is shaking the camera and affecting the sharpness of your image.
Thank you! Yes, that is very much a problem. I designed it in a way that allows vibration to travel to the sensor, which I only realized later.
wow! very impressive. wonder if a set up like this could be used as a digital back for a film camera?
Avery whens the next video?
@@SenpaiSkyy soon!!! hopefully within the next few weeks :333
@@AveryDelMiller Can't wait!
Hi Yunus, amazing work. I do take pictures but I'm afraid I know little about the sensor tech or the physics involved that makes digital cameras work. Do you reckon that it is possible to instead substitute the scanner sensor for say, a more purpose built, Pi HQ Sensor and attach it to a motion system and stitch the images. I wonder if M43 cameras use that approach to make "Super resolution" pictures, since the sensor is attached to a IBIS system and physically moves. Do you think that moving a Pi Sensor could be done with a design similar to yours / or is that feasible at all? Or would it be too shaky and introduce lots of motion blur or what challenges do you think that design might face?
I can probably answer some of these things.
I have a Pentax APS-C camera that makes use of the optical stabilization platform to take high-res images. I don't know how many other cameras do this.
The mechanics are a little different though -- the sensor is shifted around by just half a pixel. Some fancy computation is needed to create the resulting image, as the pixels in the four source images overlap each other.
Moving a cheap sensor in this way would be incredibly difficult, as you'd need to reliably be able to move it by only half a pixel. It would also mean that your resulting sensor area is still absolutely tiny, and the low amount of light captured would make it hard to take advantage of the increased resolution.
Scanning the sensor across the image (as in this video) probably wouldn't work very well either. Because the sensor is square, you'd need to scan in two dimensions - adding mechanical complexity and making each shot take longer. You'd also be getting much more data than you actually need, unless you're only using one row of pixels.
I think you need a telecentric lens. Telecentric lenses maintain a constant magnification over a certain range of object depths, which means that objects at different distances from the lens appear to be the same size. This property makes them particularly useful in machine vision applications, where consistent measurements are necessary, regardless of the object's exact position within the field of view.
bro that's insane. Now i'm feeling bad for trashing my old scanner.
What if you spun the sensor like in a Virtoal Boy or like the lighthouses for VR?
I suppose that would make it so you have to put the projector lens way forward and project the image onto something flat it could scan over... or do some serious correction in software?
Can you share a little bit more about sourcing scanner? What should i look for? Will this work only with standalone flatbed scanners? Does backlight type matter? Are You capturing picture with laptop or with android over otg cable? Are all scanners ccd or should I avoid some types?
Be interesting to see astrophotography with it. Stacked 500mp images would be crazy

How did you bypass the need for the lamp to initialize the scanner? I’m tearing apart an epson 1650 right now but can’t get the scanner to function unless the lamp is connected.
man imagine image stitching with that
Sick
Mate I want do this as well! Could you share a bit more about how you redesign the mechanic of the scanner?
Incredible work! I am wondering, how did you manage to eliminate the white light that all these scanners normally have internally?
Thank you. I did not eliminate it, since it is necessary for the calibration of the sensor. I used ribbon cable breakout boards to get access to the ground wire, which was then connected to a diy limit switch I made using a spring steel piece from the scanner and two screws, so that the light could only turn on in the home position.
@@yunuszenichowski Thank you so much for elaborating on that. Really clever integration. I bought an Epson V39 and hopefully I can reproduce your results with this scanner. I was thinking about adding a Nikkor lens for the optics. Thank you again!
I seem to remember kipkay doing something similar using an old parallel flatbed scanner.
Who knows, maybe the video got token down.
I got myself a Pentacon 420mm f3.6. Thought about buying a flatbed scanner to produce Gigapixel images. Would probably use once and then never again xD
Hey great project - could you share more detail on how you controlled the intensity of the light source as well as how you turned it off during the scan? Attempting a build myself and have useful images but want to push it to have adjustment in the light source intensity and to turn the light source off many thanks!
I had implemented a mechanism that controls the light using a diy limit switch and potentiometer (I believe 0-50k ohm). There should be some information about the details in the comments already.
is there a followup to this this project? i wanna know more about the build process, can you please make a video detailing the building and hardware + software optimisation of the camera?
Mega geil
This could revolutionize the scanning of negatives.
Why scan negatives, if you can just scan the scene directly :D
非常有趣的结合。
Have you considered building a rotary camera that rotates both the sensor and lens? Some 35mm camera lenses will cover this sensor at the widest part of their image circle, and that would provide an extremely sharp panoramic lens.
Pardon me, but why on earth would one want that sort of convoluted setup? The moving sensor thing in this case works specifically because it is very light, and still it is causing issues. Your idea would require a geared down stepper motor for the rotation I gather, but you'd have an issue with the focus at the edges of the image circle VS the center I think, so the top and bottom of the image would likely be both much dimmer, and have different focus than the center, one or the other being in focus but not both.
Also, I think I've seen long interval rotating mounts made for cameras pre-digital, I don't remember how they were set up but it would be easier not to have to fab the thing to test the idea.
Think more a simple linear camera that rotates about its' axis - the sensor is attached to the lens and the whole assembly rotates. Look up "slit camera" for the film version of this.
It obviously provides perspective distortion, but the tradeoff is unmatched resolution.
Alternately, if the camera were attached to a slider, the image could be captured without distortion as it sweeps from side to side. The lens is best at the center; why not move both?
@@noth606
Awesome project. Have you been standing on the Lange Brücke in Potsdam sometime in january? I think I may habe seen you there. I was wondering about that big camera. Funny how the CZcams algorithm works!
That must have been me, such a weird coincidence :D
forsen baj
Would it be possible to use it for astrophotography? Or attached to a telescope?
Dude you built a fckn camera, that alone just blows my mind
Nice build, but I would like to use the scanner system on a moving object (the sky with its stars) so I don't have to move the sensor relative to earth I just wait until the earth has captured a big enough portion of the sky. Should be possible in theory or did I miss something.
but noise will probably be a big problem, but if I'm honest the noise thing is a quite common problem for night sky and with tradtional cameras it is solved by taking many pictures. So maybe moving the sensor so that it scans the night slower than earths rotation would and so more time for the light to come to the sensor.
I believe linear sensors are also used to monitor conveyor belts, so it is definitely a thing. However, the maximum duration of a scan with my scanner is about 10 minutes, so you wouldn't be able to capture the whole night sky.

Very cool, I have always wanted to make one myself. Where in Germany are you? I am in Nürnberg myself..
Does a medium format lens cover the scanner sensor? Wouldn´t that be on the same page as a large format camera?
right, an 8x10" lens would make more sense. but either way to get reasonable images one would have to drop the DPI way down and even then it would only be useful for landscape photography.
Which is why, in the far far future, I will get a massive office scanner on a dolly, with a massive lens, to take some insane megapixel photos.
I'm curious about the actual image taking process, do you connect the camera to a laptop or pad and use the original software to capture an image?
Exactly, annoyingly it has to be connected to something like a laptop or windows tablet, in order to work. Maybe it could be improved by integrating a raspberry pi, but that wouldn't be cheap.
wait, 2:57 - are you saying this camera captures IR by default? I'm wondering if it would be easy to emulate aerochrome with this camera. Is there raw output? Some people remove the IR filter that came with their digital cameras in order to do this.
Yes, it does capture IR. The scanner software has an option for .bmp
If you made this IR you might be able able catch photos of the exotic vehicles in the sky
I'm working one on making one based on your models and I have a question. Are you controlling the camera with a laptop or something or are you able to control the camera standalone?
Yes, a laptop or something with windows/mac os is needed for operating the camera. I think, with proprietary software, you can also run the scanner with Linux on the Raspberry Pi.
To be honest, the requirement of carrying a laptop around is really one of the bigger downsides of this design.
Did you publish any info on the electronics and software?
I do wonder how difficult it would be to attatch it to, say, an RB67 🤔 kind of like how they have those custom Instax backs
A project idea for me!
I'm a bit confused right now. Saw some other guy's video and he said that you gotta have ground glass to project your image onto. Are you scanning the direct light?
The light falls directly onto the sensor. You need the ground glass, if you use a scanner without removing its lens.
@@yunuszenichowski wait, so if I remove the glass from the scanner I don't need ground glass? So there's nothing between the lens and the sensor?
@@pastasuta The lens is not the glass surface of the scanner. There is a tiny lens inside the scanner. You would have to disassemble the scanner, to see it. Also, most cheap scanners have CIS sensors that have no external lens at all and can only focus on super close things no matter what, so ground glass would be the only option.
@@yunuszenichowski oh so the scanner in this particular video is CCD with removed lens, did I get it right?
@@pastasuta yes, exactly :)
Where can I find/download the images shown in the video?
Found some old Russian lens for cheap on eBay. Might be a good way to expand your lens collection.
