Noise in images
During shooting at slow shutter speeds, noise may appear on-screen. These phenomena are
caused when current is generated in those sections of the image pickup device that are not
normally exposed to light, resulting in a rise in temperature in the image pickup device or image
pickup device drive circuit. This can also occur when shooting with a high ISO setting in a high-
temperature environment. To reduce this noise, the camera activates the noise reduction
function.
