Chapter 3 Basic Adjustments and Settings
“STEPS FULL” will be displayed, and the value will not
be added. In such a case, delete an unneeded step shutter
value beforehand, using DELETE.
• DELETE
For deleting the step shutter value displayed in the [deg]
column in Step mode.
For additional information of the step shutter, see “3-2-2
Shutter Settings” on page 30.
FRAME RATE
Select the frame rate (number of frames per second) if a
format of “Select FPS” is selected.
The selecting range depends on the formats, as follows:
If a format other than formats of “Select FPS” has been
selected, the value is indicated in parentheses and cannot
be changed.
COMP MODE
This camera enables you to compensate for changes in the
video level when the FPS value is changed.
Two compensation modes are provided: one that depends
on shutter angles and another that depends on electric gain.
• ANGLE: Angle Compensation mode
When you change the frame rate, the shutter angle is
automatically corrected, retaining the video level.
• In Angle Compensation mode, the frame rate cannot be
changed to a lower value if the shutter angle comes to
near 0º, and it cannot be changed to a higher value if the
shutter angle comes to near 360º.
• When you activate Angle Compensation mode, the
shutter setting is automatically set to ON.
• GAIN: Gain Compensation mode
When you change the frame rate, the electric gain is
automatically corrected, retaining the video level.
The current shutter angle setting is maintained.
• Care must be taken when shooting a high-contrast
subject, as the dynamic range (latitude) may be degraded
to
1
/
2
at maximum, depending on the selected video
format or FPS.
• With the default settings, the range of the frame
frequencies that can be selected with the Select FPS
function (see page 55) is limited. With COMP MODE
set to OFF or ANGLE, frame frequencies of 8 FPS or
less are not available to minimize picture degradation.
Usage under FPS will increase noise on the picture.
To lift this limitation, change the FPS LIMITER setting
on the <OTHERS 2> page of the MAINTENANCE
menu from LIMIT to FREE.
If the setting is changed from FREE to LIMIT, COMP
MODE will be forcibly set to OFF.
