I'm looking for a off the shelf product that Is similar to an programmable OSD (on screen display) SparkFun On Screen Display Breakout - MAX7456 - BOB-09168 - SparkFun Electronics but with more power and customization. like CMUcam http://www.cmucam.org/ but with a analog video input instead of a built in camera and more processing power. it would need to have enough processing power to do something like simple frame comparison (motion detection) at 640x480, 30Hz. I would PAY to find the answer to this problem. I've written some awesome code that would be perfect to port over to a device like I described. I don't even know what you would call it.
I already sell my system for PC but it would be better to have a dedicated hardware system for it. the specs are pretty simple. It would just be a board with a processor, 2 analog video ports, power, and a way to upload new firmware. that's it. it would be most similar to CMU Cam but not as weak and slow.
that's a good find! I watched a few of their videos. their XK-1 dev kit looks good but I've got to ask them some questions first.
Could it be done even more simply though? you would have analog video in -> an ADC -> processor -> DAC -> analog out. I can't remember fully but there is some sort of signal that marks the end of each video frame. If i could just get each new frame to populate an array I'd be set.
right. there won't be any real image recognition. that is way too CPU intensive. the application is most similar to motion detection (comparing the pixel RGB values from 2 frames against a threshold). I've seen it done on some programmable digital cameras. Several slightly high end CCTV cameras have simple motion detection firmware built into the camera itself also. that OSD unit from sparkfun does what i need also but it is not customizable enough. all you can do is add characters to the video stream but it is the same idea hardware wise. there's got to be a product out there made for this stuff. it is used a lot in the security camera industry.
