ISO
The ISO function allows you to set the sensitivity of the 
camera's sensor to light. To improve the performance in 
darker environments, a higher ISO value is required. On 
the other hand, a lower ISO value is needed when in bright 
conditions. (The ISO setting is only available when the camera 
is in the 
M
 
Manual mode).
Pictures taken with higher ISO will generally have more noise 
than those taken with lower ISO.
The options of ISO include automati, 80, 100, 200, 400, 800, and 
1600.
Blink Detection
Blink Detection is enabled by default unless disabled by the 
user. When shooting, if a subject is detected with closed eyes, 
the Blink Detection icon 
 will appear on the screen to 
indicate possible blink.
