| Function/Set Value | Initial Value |
Average : Peak | Sets the method of exposure detection according to ratio be- | 8:2 | ||
| tween the average and peak values. |
| ||
| • Large Average value : Use this setting when areas other than |
| ||
|
|
| those highlighted are dark and unclear. |
|
|
|
| (Example: 10:0) |
|
| • Large Peak value | : Use this setting when halation occurs |
| |
|
|
| at the highlighted areas. |
|
|
|
| Use this setting when areas other than |
|
|
|
| those highlighted are dark and unclear. |
|
|
|
| (Example: 5:5) |
|
| Set value | : 10:0, 9:1, 8:2, 7:3, 6:4, 5:5 |
| |
Shutter | Sets the speed of the electronic shutter. | 1/60 | ||
| Set value : 1/60, 1/100, 1/250, 1/500, 1/1000, 1/2000, 1/4000, |
| ||
|
| 1/10000 |
|
|
| Notes |
|
| |
| • | To reduce flickering that occurs under fluorescent |
| |
|
| lighting, set the shutter speed to 1/100 if your local power |
| |
|
| supply frequency is 50 Hz, and to 1/60 if it is 60 Hz. |
| |
| • | The higher the shutter speed, the more prominent will |
| |
|
| be the smear phenomenon. This is a phenomenon that |
| |
|
| is characteristic of CCDs, whereby white stripes appear |
| |
|
| at the top and bottom of a bright light source. |
| |
|
|
| ||
AGC | Sets the maximum gain of the AGC (Auto Gain Control), which | 10 dB | ||
| electronically increases the gain when the object is under low |
| ||
| light conditions. |
|
| |
| OFF | : Disable AGC. |
| |
| 10 dB : Increase gain by a maximum of 10 dB according to |
| ||
|
| the brightness of the object. |
| |
| 20 dB : Increase gain by a maximum of 20 dB according to |
| ||
|
| the brightness of the object. |
| |
| Note |
|
| |
| • The screen may appear grainy at dark places when the |
| ||
|
| gain level is increased. |
| |
|
|
| ||
BLC | Sets the backlight compensation function. Use this setting when | OFF | ||
| an object appears dark using the Auto Iris function due to the |
| ||
| presence of a bright light source behind the object. This func- |
| ||
| tion makes it possible to place an unnecessary light source |
| ||
| outside the photometry area. |
| ||
| OFF | : Disable BLC. |
| |
| Area 1 to Area 4: Set accordingly by referring to the diagram below. |
