Chapter 5 Shooting — Flash band compensation (FBC) function
Flash band compensation (FBC) function
The camera is equipped with a function for compensating and reducing band-like interference (called “flash band”) that occurs due to the MOS pickup
device when shooting in environments where flash strobe light such as that from still cameras is present.

NOTE
t
When the flash strobe lights, the following phenomena may occur. These are due to the flash band compensation function and are not malfunctions.
- Moving subjects look as if they have stopped suddenly.
- The resolution when the flash strobe light drops.
- Horizontal lines appear in the video when the flash strobe lights.
- Flash bands may appear only in images shot at the time the flash is fired.
Using the flash band compensation function
The flash band compensation function is activated when there are large changes in brightness at the bottom of the screen regardless of whether there
is flash strobe light. The flash band compensation function may be activated depending on the shooting environment such as where a bright window has
zoomed in and then out. So, we recommend use of this function in shooting environments where flash strobe lighting is anticipated.
Even if flash strobe lighting occurs, sufficient flash band compensation function effect may not be obtained in some shooting environments.
Flash band compensation function operation conditions
f
The flash band compensation function can be used under the conditions that electronic shutter and digital super gain functions are all not operating.
f
Even if the flash band compensation function is enabled, the flash band compensation function is temporarily disabled if the camera is changed to a
mode where the flash band compensation function cannot be used.
When using the function again, return to a mode that can use the flash band compensation function. Flash band compensation function will be
automatically enabled.
The flash band compensation function is disabled once the power is turned off.
