No - that will be a major redesign - our cameras do not have a disk interface.

Thank you, Andrey for clarification. How much cost work to make a such solution camera:
Compressed RAW from CMOS direct-to-disk and streaming proxy (low 1/2 or 1/4 resolution) through GIGe ?

I think it would be out of the way for Andrey right now. he makes High resolution Network cameras mainly for security purposes. This thread is for tests done with his current design to make it possible for filmmaking. His design right now really really good quality. I should be getting my lenses in these few days. and ill show you what i mean.

I got my camera a few days ago. I'm not able to do tests this week because I'm out of the country, but I'll follow this thread and post my results when I'm back.

heres a test with the new f1.3 computar varifocal lens:

sorry for the horrible lighting, i had the blown out areas because that paper is glossy and i was getting light reflected from through the windows from outside. and my back is basiaclly a wall of french doors, (glass doors) so they all are windows.

Pardon my ignorance, but can this camera acquire motion video at more than 8 bits deep ?
Other than that, what are we gaining over a normal HD video camera , other than something to tinker with ?
It's good to see people trying out new devices! keep it up!

have a look please
 

bonjour

as I did tell you,
have a mechanical shutter,
use a classical viewfinder

I lost this link
voila
here it goes
www.arri.de/entry/416.htm

nothing is dead, it is brand new

a really good one, who knows??

direct to disc
a huge choice of lenses
and so on

Ronald, would you have any idea as to know how sync a 180 degree shutter to the Elphel's stream? It would be very cool in theroy, but i dont think id be able to build something that would cover the light at the right time inervals.

and after that was built, the viewfinder would go next.

Thank you for that link, i think i figured out what else i need to make the viefinder i was going to make. that pechan prism looks very handy.

an old one

a question
 

So
maybe an idiot one
but how to get sync out of this board??

The 3mp micron chip that the elphel uses is capable of running snapshots in global reset mode which means all the lines are exposed at the same time, but this requires a mechanical shutter to cut it off at the end (i assume exposure time becomes longer for the lower lines because they just keep exposing until readout gets to them or something). also the chip has the ability to recieve an external trigger that begins a frame. I assume that if you run in global reset mode with a mechanical shutter, you lose the ability to have much longer than 180degree shuttters, but rolling shutter artifacts would be totally removed. The question is whether or not elphel has support for these functions and if you can find a way to hook up a crystal to the camera and the shutter. WIthout this, i dont think a mechanical shutter would do much since the actual exposure period of the first and last rows, in many configurations, hardly even overlap at all, so youd just end up reducing the exposure of probably the first and last rows, basically darkening the tops and bottom of the frame.

Andrey,

Just curious, I downloaded the open source stuff and was picking through you FPGA code.

Since I'm not to familiar with Verilog (I'm coding in VHDL) I was wondering if you have any documentation to go with the compressor. Is all the compression done in the FPGA, I only took a quick look and its hard to tell from unfamiliar code, or do you have to do entropy encoding in the processor or something.

I'm pretty sure that their would be translation tools out there, from one to the other, if that would help you.
