Noise in images
While 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. [Noise Reduct.]:
