Reviewers using Blur Busters Testing Techniques

Several display review websites have adopted Blur Busters testing techniques, including the motion blur photography technique invented by Mark Rejhon of Blur Busters. For more information about the Blur Busters pursuit camera technique, see the peer-reviewed paper and also pursuit camera instructions with the motion tests at www.testUFO.com.

Here are some websites that have adopted the Blur Busters pursuit camera tests:

HDTV Test

HDTVtest.co.uk – Display testing website in UK:

PC Monitors

pcmonitors.info — A website run by Adam Simmons who tests computer monitors:

RTINGS

rtings.com — HDTV buying recommendations on a Montreal-operated website.
    “To validate that our camera goes at exactly the same speed as our logo, we are using temporal tick marks placed just below the logo. This technique was invented and proposed to us by Mark Rejhon of Blur Busters, a website dedicated to the reduction of motion blur.”

TFT Central

TFTcentral.co.uk — A display review site in U.K.
    “We used the Blurbusters.com Ghosting Motion Test which is designed to be used with pursuit camera setups. The pursuit camera method is explained at Blurbusters as well as covered in this research paper. We carried out the tests at various refresh rates, with and without ULMB enabled. These UFO objects were moving horizontally at 960 pixels per second, at a frame rate matching refresh rate of the monitor.”

TechPrn (Phillipines)

www.techporn.ph — A tech review site in Phillipines.
   “Setting up a pursuit camera courtesy of Blur Busters allows us to a great extent, perceive the actual motion blur of the display. Using such method also allows us to check out for other motion artifacts including ghosting, inverse ghosting and other artifacts. My current hand-driven camera rail setup for this method provides excellent results, but it is far from perfect. This pursuit camera test is a peer-reviewed invention.”

    Original Polish“Metoda śledzenia obrazu kamerą była już od dłuższego czasu stosowana w przemyśle. Ceny sprzętu oscylowały jednak w okolicach 30 000$ za dedykowane systemy, co było raczej barierą nie do przeskoczenia. Jakiś czas temu pewien inżynier – Mark Rejhon z serwisu BlurBusters.com– opracował jednak metodę „ręczną” wymagającą trochę mniejszej inwestycji, ale i większej cierpliwości przy wykonywaniu pomiarów    Obiekt testowy dostępny jest bezpłatnie na stronie TestUfo.com Kluczem do sukcesu było zaprojektowanie specjalnej ścieżki synchronizacyjnej, która pozwala ocenić, czy dane zdjęcie zostało zrobione z odpowiednią prędkością poziomą i pionową. Robiąc zdjęcia używamy bowiem ekspozycji 1/15 sekundy przy 60Hz lub 1/30 przy 120Hz. Nakładamy więc na siebie cztery klatki obrazu i każda z nich musi być w tym samym miejscu względem obiektywu!
    Google Translate English: “The method of tracking video camera was for a long time used in the industry. However, hardware prices oscillated around the $ 30 000 for dedicated systems, which was rather a barrier insurmountable. Some time ago an engineer – Mark Rejhon the service BlurBusters.com – but developed a method “manual” requires a little less investment, but more patience while measuring    object test is available free of charge at TestUfo.com key to success was to design a special path synchronization that allows you to assess whether the photo was taken with appropriate speed horizontal and vertical. Taking pictures using exposure for 1/15 second at 60Hz or 120Hz at 1/30. So we put on ourselves four frames of image and each of them must be in the same place relative to the lens!”

SweClockers

Sweclockers.com — large hardware testing site in Sweden.
    Original Swedish: “SweClockers använder testufot hos Blurbusters för att med en så kallad chase camera monterad på skena följa rörelsen över skärmens yta. Detta ger inga siffror eller liknande men är ett bra sätt att dokumentera hur eftersläpen ser ut.”
    Google Translate English: “SweClockers uses TestUFO of Blurbusters to a so-called chase camera mounted on rails to follow the movement of the screen surface. This gives no figures or the like, but is a good way to document how motion blur looks.”
