can i use dis cam module n mbed for video image processing ?

Hardly, as the camera embeds a JPEG engine and delivers compressed images. For image processing you want raw, uncompressed, data...

Oops, the camera & firmware are capable of delivering raw data, which is more suitable for image processing. But a 640x480 image in 256 gray requires 300KB of space. This is about 5 times the amount of RAM on the chip...

Hi,

4D Systems' uCAM can probably do the job. It has options for lower resolution, for raw & jpeg formats. It works over serial.

Here are some links: http://www.4dsystems.com.au/prod.php?id=75 http://www.youtube.com/watch?v=oGO1Uj8k1ao

However you might need to write a new library for this...

Hope this helps. Regards, Anna.

For those that don't know this already, this camera module has been out of production since approximately the beginning of this year. Comedia makes a newer, similar model (the C329), but it costs about 60-70% more than the $US$50 C328 that it replaces.

In addition to the 4D camera mentioned above, there is another camera from LinkSprite that is in the same price-range (US$50) as the C328, and SparkFun, among others, carries this camera. Yet another camera called the C429 is available from Saelig. There are also at least two other camera modules available from Chinese sellers on eBay, and while cheaper, they are less well documented.

At a higher price level ($150-200?), there's the 2-3 versions of the CMUCam to consider.

I would expect that all but the C329 would require a completely different library than this one.
