Digital cameras, when they are excessively used, can freeze on you. Canon cameras have a reset function that can shut down your camera then power it back up. Resetting is mainly needed when the LCD screen has frozen while viewing or taking a picture, according to the Andy Ozment website. The reset function can help you skip a call to a Canon technical representative or sending the camera back to the Canon headquarters.
