Hi guys,

I'm after a couple of CMOS or CCD image sensors for a project, but my=20
searches are coming up dry... Does anyone have anything like this in=20
their junk box?

   - Monochrome sensor (although a Bayer-pattern sensor might work for=20
testing)
   - 640x480 resolution or thereabouts
   - 30fps at max resolution, but ideally somewhere around 750 to=20
1000fps max. with a window size of around 256x256.
   - Ideally some form of Subsampling or Windowing to allow frame rate=20
to be increased
   - Ideally on-board A/D converter (though I can tack on an external=20
one if absolutely necessary).
   - Nice, easy interface -- something I can wire up to an FPGA.

I did find the Cypress LUPA-300 (CYIL1SM0300AA) at Digikey, but at =A3216=20
and change plus VAT, it's a little on the expensive side. On the plus=20
side, it'll do nearly 250fps at 640x480 monochrome, 488fps with 2:1=20
Vertical Subsampling (640x240 res), or 1076fps with Windowing set to a=20
256x256 square in the middle of the sensor.

Does anyone have anything similar in there junk box (even a bog-standard=20
mono CCD / CMOS sensor I could use as a starting point would be useful),=20
or know of any similar devices which might be worth considering?

"Easy interface" seems to be the killer. Some of the old Omnivision=20
sensors were pretty easy to deal with (I2C control and pixel clock in,=20
parallel data, data-valid and frame-sync out).

What I'm trying to do is build something along the lines of this:

I'd rather not track down, buy and destroy an EktaPro, but I've got a=20
couple of "Hamfest Special" CCTV cameras (erm.. actually... six) which=20
I'm not averse to cannibalising for C-mount lens mounts. I've also got a=20
couple of P8079 image intensifier tubes, and I think it would be rather=20
neat to bolt one of those onto a LUPA300 or similar sensor.

Of course if anyone has a really good reason why this is a stupid idea,=20
please feel free to speak up!

Thanks,
