Chapter 4 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 been stopped for a moment.
- The resolution drops when the flash strobe lights.
- Horizontal lines appear in the video when the flash strobe lights.
- Flash bands appear only in images shot at the time the flash strobe lights.
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

The flash band compensation function can be used when all of the following conditions are satisfied.

function.
The flash band compensation function is disabled once the power is turned off.
