Auto gain control (AGC)
The AGC (Automatic Gain Control) is used to increase the brightness of an
endoscopic image electrically, when the brightness of the image is dark because
the distance between the endoscope's distal end and the object is too long. This
menu sets if the AGC function is used. When the AGC function is set, the
function can be switched ON and OFF from the keyboard and remote switch
during observation (see “Automatic gain control (AGC) (“F6”)” on page 89).
