Default Does a digital camera still use a lens shutter or focal plane shutter?

With the new technology in digital imaging and sensors, does a digital
camera utilize a physical lens shutter (or focal plane shutter in an
SLR) to let the light passes to the sensor? Or, can the image sensor
now be electronically turn on and off to allow for the light to
register in the sensor?
Thanks for info.

Most digicams have no physical shutter. That is why your should avoid
pointing the camera at the sun at any time. You can ruin the sensor.


Then what keeps the image from forming on the CMOS when you aren't taking
a picture?


Nothing. And some are not CMOS.
