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