If the on-screen program mode is on because the settings
are changed, the Menu (M) position clears the screen. For
example, if color is to be changed with the on-screen
program tool, the on-screen program window overlays the
image. To see the image and check its color appearance,
go to M position. The window disappears but the on-screen
program mode is still on. By releasing the switch, the
window will come back in the programming mode.
10.3.2 Mechanical Iris
Only a relatively small portion of the light that passes
through the lm camera’s lens reaches the CCD chip of
the video assist, because the light is shared between the
view nder, the CCD Chip and the lm. Therefore, the IVS
lens is designed for normal use with a totally open iris so
the maximum amount of light falls on the CCD Chip.
Variations in lighting are compensated by the IVS gain
control (automatically or manually).
Under certain conditions, such as when lighting is set for
low sensitivity lm (under 100 ASA), it may be that the
IVS gain range is exceeded. In this case the mechanical
iris of the IVS lens can be closed.
