Gamma
When the ambient light is so bright that may affect the projection of the details in the dim area of the image, you can
change the gamma to adjust the chrominance. The available options are 1.0, 1.8, 2.0, 2.2, 2.35, 2.5, S-Curve and DICOM.
Note for DICOM:
The DICOM option under this function can be used to enhance the gray scale level for viewing
grayscale medical images, such as X-rays for training and educational purposes only.
The projector is not a medical device and cannot be used for medical diagnosis.
Input Balance
When ambient light is too bright or changes, the projected image details may be affected, you can adjust the option to
make the projected colors of image closer to desired colors. There are two options for fine tuning Red, Green and Blue
Offset: These three options will shift the color spectrum for the whole image and change its brightness, if minimal
amount of red, green or blue appears in the gray areas, you can adjust the offset of the corresponding color
accordingly. By increasing the offset, the image brightness will become lower.
Gain: These three options are used to increase or decrease the range of color input for the entire image. If minimal
amount of red, green or blue appears in the gray areas, lower the gain of the corresponding color accordingly. As gain
increases, the contrast of the image will become lower.
HSG
HSG is a function to adjust Hue, Saturation and Gain independently, it allows for specified color adjustments that are more
intuitive. You can adjust Hue, Saturation and Gain for Red, Green, Blue, Cyan, Magenta, Yellow and white independently.
Dynamic Black
This function can be used to enhance the black levels of the projected image dynamically per the content of the input
signal if it’s set to On.
Light Off Timer
If the content contains full black frames, you can enable this function and select the preferred timer to switch the light
source Off-to-On dynamically. This can be used to eliminate the bright blocks of overlapping area in multi-projectors
application. For example, the projection light is switched off dynamically if the timer is set to 0.5 seconds and the content
contains full black frames over 0.5 seconds.
Note:
Light Off Timer is available when Dynamic Black function is turned on.
