The black balance function should be the correction which unites the black level for every pixel of the sensor
of HX-7, and after it changes a shutter and frame size, please carry it out.
If automatic black balance is turned ON, black balance will be automatically maintained at ""the "time of a
VIEW start, an ARM start, and the end of REC""." Setting of automatic black balance is set to ON in the
factory setting of HX-7.
Although this function can also be turned OFF for shortening of the time concerning a mode change, etc., a
shutter and frame size are changed, and if it records without maintaining black balance, white or a black
horizontal line noise may go into an image.
It recommends turning ON automatic black balance and employing it.
The noise of the horizontal line which turns ON shutter line noise correction can be prevented.
