VESA Releases New Spec for Numerically Measuring Motion Blur

A new “quality metric,” called the clear motion ratio (CMR), for numerically grading motion blur in digital displays was released Monday by the Video Electronics Standards Association as part of its ClearMR compliance test specification. The CMR renders a "clear numerical value" based on the ratio of clear pixels in a screen to blurry pixels, which enables consumers to easily compare the amount of motion blur from display to display, it said. VESA is giving the electronics industry “an open standard that gives consumers the confidence in knowing that they are purchasing a TV, notebook or monitor that meets the most well-defined set of blur criteria,” said Dale Stolitzka, senior principal researcher at Samsung Display’s America R&D Lab and “lead contributor” to the new spec. The ClearMR spec and certification logo program can be used with HDR displays, but the current version of the spec requires products to be tested in standard dynamic range mode for certification, said the association: "VESA is currently working on an update to ClearMR that will enable testing in HDR mode, which will be released in the future."
