The nature of CCD image sensors is such that noise in
the recorded image increases at slo w shutter speeds.
This camera, however, applies special processing to
images shot at shutter speeds slo wer than 1.3 seconds
to eliminate the noise , thereby producing high-quality
images. Nevertheless, a certain amount of processing
time may be required before the next image can be shot.
