With the new technology in digital imaging and sensors, does a

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

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?
