The configured settings will be applied to “CAM1” or “CAM2”, whichever you selected under [VIEW].
Multi-spot evaluative metering compensates for the backlighting problem by evaluating the photometry of the entire screen.
0 (low sensitivity) to 15 (high sensitivity)
0 (low brightness compensation) to 15 (high brightness compensation)
Center-weighted average metering compensates for the backlighting problem by measuring the photometry of the specified area intensively.
Configure the position and size of the center metering area.
The BLC center/window weighting setting screen appears, showing a rectangle representing the center metering area in the center of the screen.
Center-weighted average metering may not be set depending on the position of the center metering area.
To resize the center metering area, place the mouse pointer over the border of the area and then drag it.
Select a weight value for each of these metering areas depending on the installation environment.
0 (minimum) to 7 (maximum)
The weight value for the center metering area ([CENTER]) is fixed to “7”. You cannot change this value.
The brightness value represents the weight for each area and therefore does not affect the actual live video image from the camera.
The settings are saved and you return to the sub menu.
You can use light source masking to compensate for backlighting problems with human or other objects in the subject, by masking the light source in a bright background.
The BLC masking screen appears.
The masked area is indicated by blue-bordered grid cells each containing the letter “M”.
You can mask more than one portion of the live image.
You can click one grid cell after another to set or cancel the masked area cell by cell.
To deselect a block of grid cells in the masked area, right-click one of grid cell and drag the mouse.
The settings are saved and you return to the sub menu.
