independently of the iris setting. The shutter has to be switched off if lenses

This mode should be selected if lenses with with video or DC control are used.

xed iris or manual iris setting are used.

Remark At very bright ambient light (e.g. outdoor use) the shutter setting range may not be sufcient

to achieve a satisfactory video quality. In this case it is recommended to use a lens with

automatic iris control (DC or videosignal controlled).

If pictures are taken with short shutter speed settings intensity level variations may occur.

Pictures taken at articial light (particularly at uorescent light) may icker.

Flare (bright horizontal or vertical lines) may occur in the picture.

If manually controlled lenses are used, problems with the depth of eld may occur due to the

xed iris setting. The depth of eld decreases particularly if the iris is opened completely.

This could lead to parts of the picture being out of focus.

exposed if the BLC function is activated, parti-

Remark The iris control is derived from the area at the picture center.

The iris is opened if the picture edges are brighter than the center.

The iris is closed if the picture edges are darker than the center.
