Is higher resolution needed to convey true realism in video
SAN JOSE, Calif.--(BUSINESS WIRE)--Jul. 17, 2014--
Pixelworks (NASDAQ: PXLW), an innovative provider of video display
processing technology, today announced a series of white papers that
examines the dynamics of how individuals perceive high resolution on
video displays. The first paper in the series, “High Resolution Displays
and Moving Images,” is now available on the company’s website, www.pixelworks.com.
The next papers in the series will be released in the coming months.
The white paper series is a compilation of independent research
conducted by Pixelworks, as well as third party research and articles
that collectively advance the knowledge of how high resolution, or more
accurately pixel density, is perceived. In particular, the first paper
analyzes how moving images are captured and displayed, the ideal
resolution on various screens from smartphones to UHD TVs, and how
individuals perceive changes in the quality of moving images. Most
interestingly, in order to convey images that look realistic, moving
images must be displayed at a higher resolution. Unlike still images
where the objects have a fixed relationship with the pixel grid, the
introduction of motion creates distortion caused by objects
transitioning from one pixel to the next. The resulting artifacts
highlight the display’s pixelated nature, which ultimately impairs
Future papers in the series will highlight unexpected consequences of
the transition to higher resolutions. For example, when displaying video
in higher resolutions artifacts such as judder, motion blur and halos
caused by one object moving in front of another are actually more
perceptible to the viewer. This issue is particularly acute on the
displays of mobile devices, almost all of which lack the comprehensive
video display processing pipeline commonly incorporated into larger HD
and UHD flat panels.
“We’re very pleased to be able to share this information with the rest
of the industry,” said Richard Miller, Pixelworks Senior Vice President,
Technology. “We believe examining video quality at this level will spark
further discussion and interest, and ultimately result in advancing the
industry’s understanding of how to create future displays capable of
portraying the highest quality and most realistic images.”
