Basic Functions
Exposure Compensation
Exposure compensation is a function which offsets the
internal reference brightness level used in the AE
mode, by steps of 1.5 dB.

Aperture Control
Aperture control is a function which adjusts the
enhancement of the edges of objects in the picture.
There are 16 levels of adjustment, starting from “no
enhancement.” When shooting text, this control may
help by making them sharper.
Back Light Compensation
When the background of the subject is too bright, or
when the subject is too dark due to shooting in the AE
mode, back light compensation will make the subject
appear clearer.
Slow shutter – Auto/Manual
When set to “Auto,” ensures that the slow shutter is set
automatically when the brightness drops. Effective
only when the AE mode is set to “Full Auto.”
Set to “Slow Shutter Manual” at shipment.
ICR (IR Cut-Removable) Mode
EX780S is available with an IR Cut Filter, which was
used before the advent of CCD. This filter attaches
mechanically, but can be removed. Removing the IR
Cut Filter increases sensitivity to the infrared region
and allows shooting under darker conditions.
Setting the IR Cut Filter to OFF, produces a black and
white image.

Auto ICR Mode
Auto ICR Mode automatically switches the settings
needed for attaching or removing the IR Cut Filter.
With a set level of darkness, the IR Cut Filter is
automatically disabled (ICR ON), and the infrared
sensitivity is increased. With a set level of brightness,
the IR Cut Filter is automatically enabled (ICR OFF).
Also, on systems equipped with an IR light, the
internal data of the camera is used to make the proper
decisions to avoid malfunctions.
Note
When in Auto_ICR_OFF state and WB data is added (default), a
malfunction may occur when images full of blue and green
subjects are taken.
