Using a camera module from a camcorder?

Recommended Posts

Far more complex, a CCD will give you a series of analog voltages corresponding to each pixel a bit like a shift register.

You then have to digitize that, do some treatment and generate an analog video composite signal.

That's why CCD board cameras are relatively expensive compared to CMOS ones where everything is integrated in one chip. They usually have relatively powerful DSP, ADC and DAC to handle all this.
