![]() In some cases, nearly all LCD motion artifacts can be reduced by strobe or eliminated by Motion Blur Reduction settings in new gaming monitors such as ULMB or LightBoost. Can All LCD Motion Artifacts Be Eliminated? The test at used to take the pictures on this page. Blur Busters is the world’s first blog to utilize a pursuit camera for accurate capture of motion artifacts, in WYSIWYG format, as seen by the human eye. However, Blur Busters has developed an inexpensive pursuit camera method which operates in conjunction with the Blur Busters UFO Motion Tests. It makes possible accurate photography of motion artifacts. These expensive cameras are extremely accurate at measuring motion blur and other artifacts, since they simulate the eye tracking motion of moving eyes. This is simply a camera that follows on-screen motion. Pursuit camera are used by display manufacturers for testing (e.g. Pursuit Camera: Accurate Capture of LCD Motion Artifacts However, it is not a very accurate representation of perceived display motion blur and motion artifacts:Įxample: Stationary camera photo of a moving object on a display. How Were These Images Captured? Stationary Camera: Capture of Pixel TransitionsĪ stationary camera is good for photographing pixel transitions statically. The above photograph was taken during Brightness setting of 0%. Motion artifacts can appear at dim brightness settings. PWM artifacts look like repeated images, and can affect motion fludity. PWM represents Pulse-Width Modulation, a technique that many LCD backlights use for dimming screen brightness.Higher refresh rates (120Hz) or flicker (CRT and LightBoost) reduce this type of motion blur. Motion blur is symmetric for both trailing and leading edges. It is the blurring caused by eye tracking on continuously-displayed refreshes (sample-and-hold).See LCD Overdrive Artifacts FAQ for more pictures. Pixels can overshoot their final color value before bouncing back, causing bright inverse ghosting. Coronas are trailing artifacts caused by response time acceleration (RTC, overdrive, ASUS Trace-Free, BENQ AMA).This motion artifact appears only on trailing edges observe the yellow dome. Ghosting is a trailing motion artifact. It is caused by asymmetric pixel transitions: Transitions from between two colors can be faster in one direction than the other direction.Illustrations of different motion artifacts that affect clarity of moving objects on LCD displays, using the TestUFO Ghosting Test. The UFO objects were moving horizontally at 960 pixels per second on a 60 Hz LCD, and captured using a pursuit camera.
