the brightness,  the direct  light, and t he backlight ing, 
and adjusts the settings to the correct exposure for the 
main subject .
Center

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 slower than 1.3 seconds 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.
