conditions differently in different modes. The noise reduction effect grows in OFF, LOW,
MIDDLE and HIGH modes in order.
OFF: No noise reduction effect.
LOW: Noise reduction effect is small but there is little afterimage.
MIDDLE: Noise reduction effect is generally effective in this mode. Noise can be
reduced properly and the afterimage is not strong.
HIGH: Noise reduction effect is excellent but afterimage is also strong.
3.2.7. WIDE DYNAMIC RANGE
This function is effective when shooting images against the sun, or when shooting a very
bright subject. When both, bright and dark areas exist, the objects of the two areas can
be seen clearly. In Wide Dynamic Range, we define wide dynamic range from LOW,
MIDDLE, HIGH and OFF.
OFF: Disable wide dynamic range.
