FEATURES
Electronic iris function
The electronic iris function regulates the
electronic shutter speed. To the contrary of
electronic shutters with a fixed speed, the
electronic iris modifies the shutter speed
according to the CCD input. The electronic
iris will automatically control the amount of
light entering the camera, so manual iris
lenses can be used on the camera.
Backlight compensation function
The backlight compensation function will
divide the screen in two areas (
A
) and (
B
),
as illustrated below. Then, the iris is
automatically set so the outside zone (
B
)
brightness is given less weight than the
brightness from the centre zone (
A
), giving
the best possible image.
