3D Jitters

[admin_exported]

I was recently in the Sony Showroom in Tokyo (thankfully back just prior to the volcanic ash problems!), where they demonstrate all the latest and greatest Sony has on offer at the moment. I checked out their 3D display with two side by side tvs (not sure which models they were). One was playing some kind of nature channel demo (polar bear swimming around kind of thing) and the other had a game demo running.

What struck me as part of this demo, was firstly, that both screens looked out of focus/fuzzy when watched without the glasses (not sure if this is to be expected or not) and secondly, that the game demo seemed to be quite jittery (though the nature video was very fluid).

I had thought that it was possible to watch a 3D movie where some people (wearing the relevant 3D glasses) would get a 3D experience and others watching the movie without the special glasses would just get a 'normal' 2D experience.

Has anyone had a similar experience or be able to offer an explanation why the above issues occurred?

3D works by displaying 2 slightly different images next to each other, without the glasses to give the illusion of one image it's not going to be a particularly satisfying experience.

You were watching Sony 3d active shutter technology you will need the active glasses to see 3d image otherwise you will see the image as you describe ..... maybe in the future you will be able to see 3d image without the glasses

Well, no - the 3D system uses alternate frames for each eye, so watching without glasses is always going to give a fuzzy, ghosted effect. So, it's specs all round or not at all.

As I reported in my Technicolor blog report, there's some work going on there to provide TVs with an adjustable 3D depth control, so that content would be more viewable by those without specs, at the expense of some 'flattening' for those with the goggles in place, but this is in the development stage at the moment.

As for the games, not an area of personal expertise, but as reported in today's news piece on the PS3 3D upgrade, there's not actually any real game content yet available for the new 3D systems

Great, thanks for the quick replies all.

Presumably then, when watching the same tv in 2D mode, it only shows a regular picture (ie one image, rather than 2 side by side), and so behaves like a regular (non 3D) tv. I guess Sony were just demoing an early version of a game (it was more like a game trailer / advertisement) and are still working through the issues of getting it to run smoothly. It'll be interesting to have another demo once there is some proper content available.

Yes, in 2D mode it just shows normal TV images, though there has been some talk of sets able to convert 2D content to 3D 'on the fly', the mere thought of which gives me (and probably the picture) a nasty case of the shudders...

Sorry Andrew ... just a little correction :

Altough sony and other brands are trying to lunch a processor that can transform 2d in 3d Samsung is beyond that and already has that technology in their new 3d sets as we speak ... 2d to 3d conversion - as we are talking about not 3d original content is obvious the experience wont be that immersive as original 3d is but users are giving it a positive review as it introduces some deep in image perception ... also gammers enjoy this ...

Indeed, but I was referring to the Sony sets the OP had seen: and as for on the fly conversion, gammy would be the word I'd use...

The conversion technology is a gimmick at best IMO.
