Plasma group proposes new approach to measuring HDTV resolution
The Advanced PDP Development Center (APDC) last week announced the development of the Moving Picture Resolution Measurement System.
The system is based on a method the group announced Oct. 18, 2006. The new system makes it possible to conduct precise measurement of moving picture resolution, APDC said.
Hitachi, Matsushita Electric Industrial (Panasonic) and Pioneer jointly established APDC to promote the development of advanced engineering and manufacturing technologies for plasma displays.
According to the center, the claim of 1080p resolution in many HDTVs is based on the number of picture elements, or pixels, visible when a still picture is displayed on the screen, 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, controller PC and image data processing software. In the process, a specified test image is scrolled on the display to simulate a moving picture. The movement of the camera is adjusted to the movement of the image so that it can be captured. The image is then captured by the digital camera, analyzed and expressed mathematically to indicate the precise moving picture resolution.
Because 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, according to APDC.
The new measuring system is applicable to any display, including plasma and LCD TVs, according to the group. APDC plans to propose the use of this measurement system to all display and TV manufacturers.
