Day/Night Settings: IR Cut Filter
The
Auto Mode (AE) allows adjusting the light sensor’s sensitivity to day/night conditions to
fine tune the IR cut filter operation when the Auto Mode (Light Sensor) isn’t optimal for a
specific environment.
In Transfer Threshold are 2 settings: From Day to Night and Back to Day.
From Day to Night has a range (+10 Bright to -10 Dark) which can be used to adjust the
sensitivity of switching from day to night. A larger From Day to Night value will result in a
switching to Night mode in lighter conditions, a lower value requires darker conditions to
switch.
Back to Day also provides a range (+2-+12) which adjusts the sensitivity of the switch from
night to day. This value relates to the From Day to Night; the switch to day mode is based
on the From Day to Night + Back to Day values.
NOTE: Auto Mode (AE) doesn’t differentiate between IR light and visible light. Subsequently,
IR light can cause the IR-Cut filter to switch back to Day mode.
While in night mode, if an object is close the image will appear bright from the IR light and
result in the Luminance Metering to register a high value which can switch the camera back to
Day mode. This is due to Auto Mode (AE) using image brightness.
So
, the camera shouldn’t use this setting in environments where objects are close creating a
“bright” image. Alternatively, set the Back to Day to a high value to counteract this behavior.
