Looking for a Camera
« on: December 17, 2007, 05:26:09 PM »
Hey guys. I'm looking for a small camera that would be easy to interface with a micro. I've found a few on this site that have a lot of processing hardware on them but I just want a basic camera with a serial or maybe an 8-bit interface without any extra tracking ware.

How do you plan to interface with the camera?

Both the AVRcam and the CMUcam use the same Omnivision OV6620 CMOS camera (~$60). You can just buy that separately from the extra hardware.

Ideally I'd just wire it to a port on my micro. What I'm really looking for is a camera chip like the OV6620 mounted on a board with a lens and pins or a connector that I can solder to.

If you can help me find something like this I'd be grateful : )

You just need make a wire connector and attach headers.

notice the row of holes at the top:


stick this male header into those holes and solder it on:


and finally, make your wire connector:

Ah ha! ^That's what I've been looking for. Would you recommend getting one from Electronics 123 as you got the picture?

I have never bought the camera alone. Make sure the one you buy was made after 2005, as they had a large batch of cameras with badly angled lenses.

Ive got one of the cheapish camera modules coming from spark fun, it seems quite easy to interface its got a pulse line, 8 bit data bus, hsynch and vsynch (and an i2c control interface).
basically when the vsych pulses high, it signal a new frame. When the hsynch pulses high, it signal a new line. when the pulse line pulses, it signal a new byte available on the 8 bit data bus.

I'll probably slow its clock down and use a dedicated pic at 20mhz to interface to it and send the data to ram. Maybe another pic to reduce image size/ convert it to a smaller image for ease of use, and act as a go between.
