Autofocus Video Cameras Autofocus in a video camera is a passive system that also uses the central portion of the image. It changes focus when something passes between the subject and the lens. Autofocus video cameras work best in bright light. Switch to manual focus in low light. Point the camera toward a TV remote control.
Camcorders typically use CCD imaging chips.
These chips are sensitive to infrared light. That's why your camera shows a white spot where the remote's infrared source is located. Inc. All rights reserved. Simply register for a free Postbox in the country where your merchant is located.
