Video Monitoring Features
The PIX 250i includes various monitoring features to assist with exposure and focus. These functions
only affect signal on the LCD display and will never affect the recorded video or the video output
signal.
Exposure Assist

FILES
Exposure assist features mark areas of the video image based on the exposure level. With over- or
under-exposed areas of the image clearly marked, adjustments can be made on the camera to ensure
that the signal reaching the recorder has a proper exposure. Exposure Assist is enabled by pressing
LCD FILES button. When Exposure Assist is enabled, “EXP” is displayed on the OSD in
yellow text.
When exposure assist is enabled, False Color or Zebra stripes will be overlaid on the LCD monitor
signal. The Setup Menu option
[LCD Monitor - Exposure Assist]
determines which mode will acti-
vate when exposure assist is toggled on.
The following image is a luminance ramp signal displayed on a PIX 250i with no exposure assist en-
abled. Screen shots in the following sections show the effect of the various Exposure Assist features
on this test signal.
False Color
False Color exposure assist mode replaces pixels with a specific color relative to the luminance level.
The two types of False Color (selectable from Setup Menu option
[LCD Monitor - Exposure Assist]
)
are 12-step and 4-step.
