Chapter 4 Basic operations
Adjusting the brightness
1
GAIN mode switching (LX only)
Press the [LIVE/GAIN] button on the control unit while the live image is displayed. This
switches the image’s GAIN mode. When this operation is performed, the monitor screen
shows the GAIN mode for about 3 seconds.
Switch the GAIN mode if the image is noisy or there is a dark area and you want to make
the image brighter.
The following four GAIN modes are available.
2
Automatic brightness adjustment with the [BRT] lever
While the live image is displayed, tilt the [BRT] lever on the control unit toward [
S
] to
brighten the overall image or toward [
T
] to darken it. When the image brightness is adjusted,
the LCD monitor displays the level indicator for about 3 seconds.
Use the [BRT] lever when you want to change the overall brightness of the image.
When using the stereo measurement adapter on the LX, the gain mode cannot be switched.
Monochrome boost
While a live image is displayed, you can switch to high-sensitivity image display by
pressing the [BRT] lever towards [
S
] until [BRT] (brightness) reaches its maximum
setting (Level 8). The live image becomes monochrome during the gain boost
display. This function is effective when it is required to observe the image under high
brightness than the standard, for example when the subject is very dark. Note that
the image noise may increase under certain observation conditions.
When using the stereo measurement adapter on the LX, the monochrome boost
function cannot be used.
NOTE
•
The live image is displayed in monochrome when the monochrome boost function is
activated.
Mode
Description
AUTO
The mode used to automatically change dynamic range when BRT is
interlocked. Note that this mode may be accompanied with increased
noise depending on the BRT setting.
WiDER1
The mode to use when a brighter image than is possible in “AUTO” is
desired. Note that this mode may be accompanied with increased noise
under certain observation conditions.
WiDER2
The mode to use when a brighter image than is possible in “WiDER1” is
required.
“WiDER2” further expands the dynamic range so that dark positions can
be observed. But the noise may increase under certain observation
conditions.
