Noise
While shooting at slow shutter speeds, noise may appear on scr
een. These phenomena
occur when the temperature rises in the image sensor or image sensor internal drive circuit,
causing current to be generated in those sections of the image sensor that are not normally
exposed to light. 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.
