Plasma Center to Measure HD 'Movement Resolution'

It looks like the battle between LCD and plasma proponents has a lot of life left in it, as some key plasma makers try to establish a new standard, of sorts, that could demonstrate what they contend are plasma's advantages.

It looks like the battle between LCD and plasma proponents has a lot of life left in it, as some key plasma makers try to establish a new standard, of sorts, that could demonstrate what they contend are plasma's advantages.

The Advanced PDP Development Center Corp. jointly established by Hitachi, Matsushita Electrical Industrial and Pioneer to promote the development of advanced engineering technologies for HD plasma displays, has developed what it calls a Moving Picture Resolution Measurement System--based on its own APDC Method announced last October. The system was designed to precisely measure the "true resolution of moving images."

The three firms said that "the claim of 1080p resolution" in many HD sets is based on the number of pixels visible when a still picture is displayed on the screen, not a moving image.

The new APDC system includes a digital camera, signal generator, controller PC and image data-processing software. The process consists of three steps:

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 it can be captured.

3) The image is captured by the digital camera, analyzed and stated mathematically to indicate the precise moving picture resolution.

The group said its new measurement method simulates the human eye by reconstructing the image reflected on the retina--with the result of the quantitative analysis being very close to the way people see images in the real world. The measuring system is applicable to both plasma and LCD screens, the APDC said.
