1. iboson Vismotion-M, a visual motion analysis system designed for measuring response times, motion blur, and other performance metrics in displays, light sources, and optical systems. This system employs high-speed imaging and advanced analytical algorithms to capture image variations, enabling the assessment of devices' rapid response and motion blur characteristics. Vismotion aims to provide users with a comprehensive understanding of visual system performance, offering valuable insights and data for optimizing product design and manufacturing processes.
  2. Vismotion-M has developed the latest VESA CMR measurement functionality and integrated it into the same system, which is faster and more convenient than using a general high-speed camera to measure CMR.
  • Mimics eye tracking to directly quantify motion blur levels on VR displays.

  • Advanced software techniques, smooth scrolling images are directly sent out by the graphics card.

  • MPRT measurement simulates human eye behavior to quantify actual motion blur situations.

  • Unique alignment correction technology ensures more accurate measurement results.

  • Images and curves are simultaneously recorded and can be reviewed for research purposes at any time.

Why does VESA need to develop CMR?

MPRT Issues
  • People are less sensitive to time representation and cannot accurately distinguish differences in ms levels.
  • Many image enhancement and blur removal techniques cannot be fully represented by time-based metrics alone.
  • Excessive overdrive causes artifacts and distortion that can negatively affect image quality.
  • Improving the current performance of certain grayscale MPRTs that work particularly well is considered a matter of specs.
Advantage of CMR 
  • Allowing consumers to fairly compare the motion blur qualities of display products.
  • CMR specifications are divided into 11 levels by grade, and the difference in grade can be directly felt.
  • Higher CMR numbers indicate higher image quality and less blur.
  • With a viewing angle of 10 degrees and an observation distance of 1.5 times the height of the screen, a scrolling Bar moving at a constant speed has a blurred and clear ratio at the interface between light and dark.
  • CMR calculates gray levels not as equal gray levels, but divided according to brightness 25%, 33%, 67%, 75%, and 100%. The measurements are respectively CMR leading and CMR trailing. Calculate the overall CMR according to the formula.
  • In the past MPRT measurement, the monitor could achieve beautiful measurement data by over-adjustment, but this would cause side effects on the screen. CMR limits the overshoot/undershoot ratio. It is recommended to turn off Backlight Strobing.

CMR Blurred Edge BEW definition changes

  • When MPRT is measured, the width of a fixed 10% ~ 90% brightness (blue point) is used to push back the entire blur range, so the blur range will be greatly underestimated.
  • CMR is calculated using the inflection point (black point), so the blur range can be calculated more accurately.
