Talk:Persistence of vision

From Wikipedia, the free encyclopedia

This needs lots more work. We need to distinguish more clearly between flicker fusion and the illusion of flow, and discuss temporal aliasing a lot more. -- The Anome 09:46 7 Jun 2003 (UTC) exist? Don't we in any case need an explanation for why we perceive things the way we do? I'm confused. Vivacissamamente 04:52, 31 October 2005 (UTC)

[edit] cartoons

someone might want to mention in the animation section that some cartoons simulate motion blur in the drawings, because you can't actually get that in 2-D animation. (might be easier to mimick now w/ CGI cartoons and stop-motion animation, but in the old fashioned animation they had to actually draw the blur into the actions)

[edit] Blinking LED

A fast bliking LED will produce a snow flake, plaid or Persian rug like pattern in the eye, especially with the eye closed and the light passing through the eyelid. Which theory dose this support? Is this the scan pattern of the eye? Is the pattern the same in eveyone or not? It is said that some people have trouble reading due to the letters blurring and changing color as they are scanned.

  • I don't think this has anything to do with persistence, but I may be wrong. I had an impulse to remove that section from the article, but I'll leve that to others... --Janke | Talk 08:11, 29 November 2005 (UTC)
I went ahead and removed the LED section. We need a reference that proves it belongs here. --Janke | Talk 11:08, 1 January 2006 (UTC)

[edit] Persistence of Vision as a myth.

How should http://www.uca.edu/org/ccsmi/ccsmi/classicwork/Myth%20Revisited.htm affect the article? Should "Persistence of vision" be categorized as pseudoscience?

Interesting... As the wiki article says, there is a division among scientists and film scholars. I have inserted a note about it being considered a "myth". --Janke | Talk 07:00, 30 May 2006 (UTC)

I'm sorry if this is harsh, but I just gotta say it: I find it mildly amusing that a little bit of insight into neurology and physics could have prevented this entire doomed branch of film theory from ever having sprouted (well, continued anyway). It might as well be astrology. So, yes, I guess you could say persistence of vision is pseudoscience (even though it's a pretty harmless phrase), but the Andersons' paper is full of a whole bunch of unnecessary (at best) or irrelevant (at worst) counter-argument. Skip the psych experiments and just extend the concepts of high school science. For example, what the Andersons' (and others) refer to as "real motion" doesn't even exist. All motion is merely "apparent". How could it be any other way, given that your eyes are connected to your brain by neurons, which are discrete conductors of information (see Refractory_period#Neurology_refractory_period)? On top of that, the photons hitting the retinas are discrete, whether they're coming from a movie screen or your hand waving in front of you. There's nothing essentially different about seeing pictures as moving and seeing "real objects" as moving. If what you're really interested in is what the thresholds for perceiving motion are, then study psychophysics. Otherwise, you're attempting to answer the binding problem. --MilFlyboy 02:52, 1 October 2007 (UTC)

[edit] Eye is not a camera

Well, it's not, but this: "the eye is not a camera: there is no "frame rate" or "scan rate" in the eye: instead, the eye/brain system has a combination of motion detectors, detail detectors and pattern detectors, the outputs of all of which are combined to create the visual experience." does not really work well. For one, it being a combination of such detectors does not necessarily mean it is not discrete. Something else should be used as justification for the non-discrete nature of the eye's processing than that. mike4ty4 08:46, 8 May 2007 (UTC)
