FBC (Flash Band Compensation)

This camera-recorder comes with a function to compensate for and minimize light band (flash band) interference that occurs with the MOS imager when shooting in an environment where flash photography is taking place.

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

•You can use FBC in the “FBC operation enabled mode” below.

•Even if the FBC function is switched ON, it will be forced to OFF if the mode is switched to one not shown in “FBC operation enabled mode”.

When you wish to use this mode again, set the camera to a mode shown below then press the USER button and switch the FBC function ON.

•Even if the FBC function is switched ON, it will temporarily be switched OFF if shutter is switched ON or the digital zoom is operated. The FBC function returns to the ON state after shutter or digital zoom is switched OFF.

•The FBC function is switched OFF if the power switch is set to OFF.

FBC operation enabled mode

•1080/60i*2, 1080/50i*2, 720/60P*2, 720/50P*2, 480/60i, 576/50i,
