Sorry I wasn't more specific. I was refering to the output interface for the video stream to the computer when everything's finished (firewire, usb, GigE...).

It's also good to know the board has a VGA output so a standard LCD can be used too.

Hum i don't know which altera board he has, but he's talking about Sd card slot so i believe it's a DE1 like mine and in this case the VGA controller is only 4 bits per color so forget about 'real' display.

edit : yes it's the same as mine, after seeing the pic on his website ;)

You can always use the general io pin to do what you want but that need more work ;)

(by the way Alex, i wouldn't mind discuss that dual port ram with you, i'm new to fpga and there is some concepts quite difficult to grasp... and if you're interested i bought a micron 1.3Mp module with it and it comes with some code for interfacing sensor and everything...but for the DE2 board so it's not working out-of-the-box :))

So we'd need to display the video via the cam-computer interface using the computer screen, just like the other possible solutions do. If it can be done while capturing in realtime, there's no problem with it.

Sorry for disappearing for a while. I changed the email I using and had to go back through the moderator Que. You guys are right on the money, I am using the DE1 dev kit, however dont discount VGA output so quick. If you look at the schematic its not that complex of a circuit. Bumping it up to 10bit per color is as easy as adding a resistors and connecting IO lines.

Im more than happy to give verilog tips and answer questions btw. Just have to ask!

What about the dual ported ram would you like to know?

EDIT: Check out the head board:

Can you tell me some more about this?
Have you considered JPEG 2000 which is wavelet?
Its the compression I think the RED is using and
delivers a much nicer video.
If you go with JPEG please allow for variable compression
rates. For me about 22MB/sec which is 6 to 1 is OK and
easy to handle.
Basically I am interested in the camera from what you
described. I am a programmer by trade.

Thanks,
Bob

My firm is currently designing a new LightWise family of cameras.

These will be 1394B which will sustain 512 Mbps of video data.
We will offer the Micron 5Mp sensor which will operate at up to 30 fps in 1920 x 1080 (1080P). This would be RAW Bayer Data. Or for fully processed images (24-bit RGB) you would need a compression ratio of 3 to 1 (which is LOSSLESS) to send live data over the 1394b interface.

This camera will be priced at under $2K.

We have other potential HD options in development also =>

ISG has 3 potential products to have you review and provide feedback to me. Please let me know if you would be interested in any of these.

1)
LW-5-S-1394b-C = 5 Megapixel camera = with a ROI setting for 1920 x 1080 pixels = 30 fps resolution with 1394b (800) with Embedded JPEG inside camera. Potentially available in January 2008. Small Quantity costs would be ~$2K or less. For fully processed images (24-bit RGB) you would need a compression ratio of 3 to 1 (which is LOSSLESS) to send live data over the 1394b interface. This will be an ISG standard product. Uses the Micron MT9P001 5Mp CMOS sensor with synchronous rolling shutter. Sponsorship could enable quicker availability.

2)
LW-KAI-2093-1394b-C = 2.1 Megapixel camera = 1920 x 1080 pixels = 30 fps full resolution with 1394b (800) with Embedded JPEG inside camera. Potentially available in January 2008. Small Quantity costs would be ~$4K Uses Eastman Kodak KAI CCD with global shutter. We are looking for a sponsor to complete this design. This sponsor would invest $18K to complete the work. For fully processed images (24-bit RGB) you would need a compression ratio of 3 to 1 (which is LOSSLESS) to send live data over the 1394b interface. This would be an identical camera as #1 above but with the Kodak CCD. Sponsor covers cost of the CCD sensor board and engineering.

3)
LW-KAI-2093-Ethernet-2NTSC = 2.1 Megapixel camera = 1920 x 1080 pixels = 30 fps full resolution with 10/100 Ethernet and (2) NTSC ports with Embedded JPEG inside camera. Potentially available in December. Small Quantity costs would be ~$4K Uses Eastman Kodak KAI CCD with global shutter.. We are looking for a sponsor to complete the this design. This sponsor would invest $15K to complete the CCD sensor board and engineering work. You would need a compression ratio of 60 to 1 to send live data over the 10/100 ethernet interface.

In mid-2008 ISG could offer these same options above with Gigabit Ethernet interfaces.

Best regards,
Kerry

Hi, Jose A. Garcia;
Did you ever figure out how much a Foveon sensor would sell for?
Can you even do 720p with that sensor at 60fps?
I was under the impression that it was toooo slow.
Thanks,
Bob

The 35mm sized Foveron F13D is under $850 for the sensor. It will do 24fps at 720p

Thanks for the reply.
Thats not cheap enough for me to play with and that doest include
a test board. It is a full sized 35mm sensor though isnt it?

I am surprised they dont mention this on their site. They only mention
640x480 at 30fps. I like the idea of the sensor for things like chroma
keying it would fantastic.

I will keep reading this with interest. I am not interested in a 3,0000 to
8,000K camera that delviers HDV with tiny sensors and cant afford to spend 20K for a RED.

Bob

It'd be great to have 3 color layers and full 35mm size even if it's only 720p. If anyone develops a board for the Foveon sensor sure I'd buy it.

Im sending out the PCB for the micron sensor board today.
Any one interested in one?

-Alex

Yes I am !
How do you plan to make some PCB prototype ?

(btw i somehow saw my first image yesterday, but i'm still struggling with quite a lot of things... well, that's what learning is :D)

I tried to log into your site but did was not able to download
the PDF. I m very late to this party but hve to ask..
Where does the Altera come into play?
Whats the board for again?

The Altera Dev kit provides two 40 pin expansion ports, so I get ~70 GPIO lines. This is in addition to the peripherals built into the dev kit (SD card slot, 8MB SDRAM, VGA port etc)

As far as adapting to the P series, from what I know of Micron parts, the interfaces are fairly standard. As in I think it would be very easy to adapt the module Im working on to pull frames from the larger sensor.


Did I answer your question about the interface on the Altera board?
(not sure what your asking)....

If you were asking about programming it, the board has a built in byteblaster cable that lets you debug over a USB port.

PS - My website = www.GooseTechnologies.com
And more to the point, my always in Flux write up of all this:

Off topic but...StreamPix&Cineform

I have info that StreamPix software now has cineform support. As Cesar Rubio says this might change all. I only wish that this combo is somewhat cheaper.

Sorry, power went out at my apartment. Server is back up now. So if you click on News, and then try the link you should be able to get the PDF

Ok got the PDF and looked at the block diagram.
I see of the chip will be used.
Was wondering why there are JPEG2000 encoders in the diagram.
Are there any images from the CCD yet?

Thanks,
Bob
