NOTE
The following phenomena that may occur in video that
includes flash light is due to FBC compensation and not
indicative of a malfunction.
• Moving subjects may appear to be stationary for an instant.
• Resolution decreases in video exposed to flash light.
• Horizontal lines appear in video footage exposed to flash
light.
Using FBC
FBC goes on when the brightness of the lower half of the
image differs markedly from the previous half, which could
be caused by light from a camera flash or other strong light
source. Since FBC may be incorrectly activated in certain
shooting environments, for example, in zooming that includes
a bright window, be sure to use the function only for shooting
footage exposed to flash light.
In some shooting environments adequate FBC effect may not
be obtained even when a flash goes off.
FBC requirements
• The FBC function is available in the 1080/60i, 720/60P (VFR
OFF) and 480/60i modes when the shutter off.
• Switching to an operating mode other than 1080/60i, 720/60P
(VFR OFF) and 480/60i turns FBC off if on.
To turn on FBC after returning to 1080/60i, 720/60P (VFR OFF)
and 480/60i, press the USER button to which the function is
assigned.
• Turning the shutter on when the FBC function is engaged
temporarily turns it off.
The FBC function goes back on when the shutter is later
turned off.
Turning the power off disengages the FBC function.
