Fantastic. There was a dude in Budapest, german guy I think, did something similar, wrote also his own software. Can't remember his name.

How do you know when your pictures are in focus or not?

@hanfo420 Ай бұрын

Just a few thoughts, I could be totally wrong. It has a higher dynamic range because you have more positions per sensorpoint (which would be e.g. the blue sensor). You could get even higher dynamic range by capturing pixel sub steps (or making it move slower but longer) and then add them together with a clever function or make the pixel shape weird. That would capture crazy large image files. But this has limits, as the sensor has a low and a high limit. To go beyond you could take the image at multiple f stops or multiple iso steps, if available.

Would be funny to capture a 4h long image and suddenly have the sky fade to black. Haha. I bet you could simulate this by rendering a timelaps into an image.

Ok so I completly lost it and built some py scripts to compile images from raw timelapses on youtube. This is a rabbithole.

I don't understand why you didn't use a 16bit camera with pixel shift. What do you get out of it, other than the fun of making something DIY? Of course, having fun is also a very important reason. 🥰🥰

2:28 I would consider monochrome full spectrum cameras used with RGB filter wheels capable of also capturing true per-pixel color. This is very common in astrophotography. Thank you for sharing your project. It's really neat!

Could you share how you were able to turn off the light source?

@raspy00135 11 ай бұрын

Just take it off, but you still need the light source to trick the initialization process

@imprune 11 ай бұрын

Many thanks for coming back to me@@raspy00135 - I wonder because the light source appears to turn off before the ccd moves in your video. I just wondered how you do it? Is it with a manual switch? or are you doing something clever with additional components? I would guess its not a limit switch because the light source turns off before the ccd moves

@imprune 11 ай бұрын

Maybe a timer 555 switch configured for 2-3 seconds?

The resolution can go very high? I'm sure that you know better than I do that this is not an accurate statement (subtitles at 1:35). You are talking not about the resolution but merely about the size of the image in pixels. Pixels themselves don't resolve anything. Resolution is the ability of the system to resolve some distinct object features as separate, so it is measured in angular or linear distance units. Nevertheless, it does not reduce the value of your excellent work. It is excellent!

@sbuntinx Жыл бұрын

Very impressive results, trying to create a scanning camera myself using a similar scanner sensor. In my attempt i try to directly interface with the sensor PCB. Using a raspberry pi pico i have been able to talk to the ADC on the sensor PCB and retrieve the image data. This should allow for manual gain and integration time settings aswell as full controll on how the stepper motor is driven. As the raspberry pi pico has a slow USB(1.1) interface i am directly writing the image data to a SD card. This seems to work quite well although i have not yet started on the mechanical part of the camera so cant show any photos yet.

@raspy00135 Жыл бұрын

That sounds fantastic. I have no idea how to interface with the linear CCD. If I don't need to rely on EPSON firmware then it might be able to do a lot of other things. One big limitation of the camera is that fixed exposure time (shutter speed).

@sbuntinx Жыл бұрын

@@raspy00135 Yes that is one of the reasons i tried to avoid the EPSON software. Luckily you don't have directly interface with the CCD as the there is already a ADC(AKM AK8419) on the back of the sensor pcb so the flat ribbon cable only contains digital signals and some power. Which does mean that the image quality should be comparable with the the output from the EPSON software. At the moment the wiring and the code is still a bit of a mess but if it seems to work well enough i will try to publish the code and designs. It seems that a lot of EPSON scanners share the same ADC and pinout on the ribbon cable so it should be quite universal. Perhaps some other configuration for the timings would be required as the actual CCD itself does differ between models. Trying now to get the sensor mounted on a old large format camera, for now i will keep the sensor fixed at the back of the camera and try to rotate the camera on a stage to get a panorama like scan.

@sbuntinx Жыл бұрын

@@will3346 I am using a v100 at the moment, also have a v330 that i plan on using later aswell. My code is not going to help with the initialization as i replaced the epson board containing usb and power connector with a board i made myself using a micro controller(raspberry pi pico) that has two ribbon cable connectors to talk to the sensor board. For the initialization using the epson board, i think it checks if the light bridge gets closed which normaly happens when the moving part of the scanner gets moved to the start position. There also might be some check where it tries to capture light at the start position to calibrate or check if the light is working. Like i said in my previous comment, the code and wiring is still a bit of a mess as i just got it working a few days ago. Planning to create a proper pcb and clean/improve to code so that i can publish it. For the moment i am working on the mechanics of the camera.
