(3) DNR (Digital Noise Reduction) (CSR: F200 00A0 h)
Improve S/N by digital noise reduction.
-OFF-
Setting value 80000000 h
-ON-
Setting value 8200000x h x: 1- MODE1, 2- MODE2
Although MODE 2 provides greater noise reduction, there is some sacrifice in resolution.
2-3. Image level related CSR
(1) (A.E) PEAK/AVERAGE (CSR: F200 0070 h)
Sets PEAK or AVERAGE signal level detection for the AUTO EXPOSURE function.
-Manual adjustment-
Setting value 8200000x h x: 0- 0/100, 1- 15/18, 2- 25/75, 3- 50/50
Set auto level control for Peak or Average in 4 steps of 50/50, 15/85, 25/75, or 0/100. At high
Average setting, background may be difficult to see in picture bright components. Increasing the
Peak setting may render spotlighted components easier to see.
(2) (A.E) SPEED (CSR: F200 0074 h)
AGC and AES response speed
-Manual adjustment
Setting value 8200000x h x: 0- SLOW, 1- MID, 2- FAST
SLOW :
Scene brightness variation rate is sufficiently slow to allow stable observing of detail.
Allows a stable image when a strong light source enters the scene.
STANDARD :
Standard setting.
FAST :
Scene brightness variation rate is too rapid to stable use of effects such as
