Line interpolation on/off

Due to the rotating mirror shutter of the film camera, the

CCD chip of the IVS gets light only for 50 % of the time. All

video assists will therefore have only one true video field

and the next one will be the repetition of the previous one.

So the repeated video field does not have new information.

To improve this situation, the video assist can be electronically

enhanced with a feature called line interpolation.

• Move the cursor > with the keys Ê and Ë to the line

– LINE INTERP. Pressing the key Í or Ì will switch the

line interpolation on and off.

Note:

This setting only affects the video image while

the film camera is in run mode.

Sharpness value

The slew rate of the video signal can be electronically

adjusted, thus creating a crisper image. However, this will

lead to more video artefacts so the best image is a balance

between sharpness and video artefacts.

• Move the cursor > with the keys Ê and Ë to the line

– SHARPNESS. Pressing the key Í will switch the

sharpness from 0 to 3 and back to 0. The Ì key will

give the opposite direction.
