3.3.3 EXPOSURE

3.3.3.1 SHUTTER

1.When the SETUP menu is displayed on the screen, please direct the arrow to point to “EXPOSURE” -> “SHUTTER” by using the UP and DOWN buttons.

2.Select the shutter mode by pressing the LEFT or RIGHT button.

Select from x256, x128, x64, x32, x16, x8, x4, x2, 1/60 (1/50 at PAL), FLK, 1/250, 1/500, 1/1000, 1/2000, 1/5000, 1/10000, 1/100000 for NTSC model or x256, x128, x64, x32, x16, x8, x4, x2, 1/50, FLK, 1/250, 1/500, 1/1000, 1/2000, 1/5000, 1/10000, 1/00,000 for PAL model.

FLK: Please select “FLK” mode when flickering occurs on the screen, because of an

irregular balance between illumination and frequency. NTSC model: 1/100, PAL model: 1/120.

3.Select RETURN and press the SETUP button when you finish all the settings.

NOTE: Make sure for default setting 1/60 (NTSC) / 1/50 (PAL), if SENS-UP function is needed in the installation. All other Shutter modes will disable SENS-UP functionality.

3.3.3.2 AGC (Auto Gain Control – basic low light signal amplification)

Please direct the arrow to point to “AGC” by using the UP and DOWN buttons.

Select the level you would like to choose by pressing the LEFT or RIGHT button. The more the level of gain increases, the brighter the screen, but the level of noise increases as well. Please select from HIGH, MIDDLE, LOW and OFF.

Note: AGC must be on for sense-up low light boost to function.

3.3.3.3 SENS-UP

SENS-UP is used to keep a brilliant, vivid screen image under low light level conditions by automatically compensating for changes in the level of light.

Please direct the arrow to point to “SENSE-UP” by using the UP and DOWN buttons. Select the mode you would like to operate by pressing the LEFT or RIGHT button.

AUTO: Low light level auto mode. Press SET for adjusting the maximum number of interpolated images. (Default is Auto, 8X)

OFF: The function is disabled.

Press select RETURN and the SETUP button when you finish all the settings.

NOTE: 1. SENS-UP will be disabled, if AGC is OFF or the default SHUTTER value (1/50 PAL / 1/60 NTSC) was changed

2.The image becomes brighter when the setting increases; however, the after image increases as well. Due to the increased light sensitivity of the Super HAD II chip, far less DSP ‘boost’ is needed, resulting in color or B/W images in low light with minimal ghosting.

3.Please note that spots and noise may appear if light amplification increases when SENSE-UP is operating. This is a normal phenomenon, controllable with DNR.
