Plasma TV makers back change in HDTV resolution measurements
The Advanced PDP Development Center Corporation (APDC), established
by Hitachi, Panasonic, and Pioneer, to promote the development of
advanced engineering and manufacturing technologies for Plasma
displays, has announced that it has developed a new method of
measuring TV resolution.
The Moving Picture Resolution Measurement System is based upon a
method announced last year and makes it possible to precisely measure
moving picture resolution.
The group says that many TVs claiming 1080p resolution base that
simply upon the number of visible pixels displayed in a still image,
which is not the same as the HDTV's moving picture resolution.
The new system to measure moving picture resolution includes a
digital camera, signal generator, a controller PC and image data
processing software. In the process:
1. a specified test image is scrolled on the display to simulate a
moving picture,
2. the movement of the camera is adjusted to the movement of the
image so that it can be captured, and
3. the image is then captured by the digital camera, analysed and
expressed mathematically to indicate the precise moving picture
resolution.
Since the APDC measurement method simulates the way the human eye
works, reconstructing the image reflected on the retina, the result
of the quantitative analysis is very close to the way people see
images
The system is applicable to any display, be it plasma, LCD, SED, CRT,
or any other you care to think of. I wonder if plasma TVs will
generally fare better under this set of measurements, in general,
than other technologies?
So there you go. Expect to see the new system developed and brought
to market as a new way to measure TVs and confuse consumers even more.
