Using Noise Reduction [NOISE REDUCTION]
When projecting a video image, you can use the [NOISE REDUCTION] function to reduce the screen noise (roughness and distor-
tion). This device is equipped with three types of noise reduction functions. Select the function according to the type of noise.
Depending on the noise level, the noise reduction effect can be set to [OFF], [LOW], [MEDIUM] or [HIGH]. [NOISE REDUCTION] can
be selected for SDTV, HDTV signal and component signal input.
RANDOM NR ...............Reduces flickering random noise in an image.
MOSQUITO NR ..........Reduces mosquito noise that appears around the edges of an image during Blu-ray playback.
BLOCK NR .....................Reduces block noise or mosaic-like patterns by selecting ON.

NORMAL ........................Automatically distinguishes a moving image from a static image to create a distinct image. Please select
[MOVIE] if there are any obvious jitter and noises.
