Accurate Photos of Display Motion Blur

A television testing website, RTings, adopted the Blur Busters pursuit camera technique. It is a proven peer-reviewed technique (conference paper). A camera on a rail, being used as a pursuit camera, is used to track on-screen motion while taking a photo. This allows accurate motion blur comparisons, similar to moving human eyes tracking on-screen motion. Pursuit camera… Read more »


Tests With 120fps Web Video In Real-Time!

Blur Busters browser tests have shown Chrome, Internet Explorer 10+ and FireFox 25+ can play 120fps video in real-time! This video is a true 120fps real-time video, not slow motion.  You must use a 120Hz monitor and a recent nVidia/ATI GPU to view this video at full frame rate.   Cameras capable of 120fps can be obtained… Read more »

HOWTO: Pursuit Camera With Motion Tests

Introduction Written by Mark D. Rejhon. Updated 2017. Pursuit camera are used by display manufacturers for display testing (e.g. MotionMaster, and other MPRT pursuit cameras). This is a camera that follows on-screen motion. These cameras are extremely accurate at measuring motion blur & other artifacts, including ghosting and overdrive artifacts. Blur Busters has invented an inexpensive method of… Read more »
