6.1 Pseudo contour
When input function is RGB 1 or RGB 2, and a gradation image (such as human face and skin) moves at a speed, the
“stripe-like shadow” may appear in that image. This “stripe-like shadow” is known as the “pseudo contour”.
This phenomenon is an illusion of human eyes attributable to the gradation expression method peculiar to the plasma
display. This phenomenon does not appear in stills picture images.
The problem of this noise (pseudo contour) has been solved by using PIONEER’s unique driving system, and achieved
high picture quality (particularly, for animation).Note that this technology is effective, only when operation is for NTSC
(interlace signal) and computer images (no-interlace signal), with MP mode ON. Therefore, when the following signals
are inputted, this phenomenon may appears when MP mode is OFF:
• VGA animation signal (when a high speed game software and video CD play on PC.
• NTSC double scanning signal (using double raster, etc.)
