HTC EVO 3D resolution halved

[greedo698]

Would any of you happen to know if the HTC EVO 3D resolution is halved while in 3D mode? According to this paper, it is possible to obtain autostereoscopic full resolution while in 3D mode...

The resolution is not halved. The Evo 3D uses parallax 3D, not autostereoscopic 3D.

ah I see....so does that mean that while viewing 3D, you are not seeing two lower resolution images?

I'm a bit confused...will the image quality be degraded because you have to break it up into two different images for each eye?

Basically, will the image clarity be equal to that of 2D mode?

Thanks!

From what i understand (someone correct me if I'm wrong) the two images are shown one after another extremely quickly so that they are basically seen at the same time. Both images are full resolution (qHD if that's the resolution of the video) and thus there will be the same image clarity as in 2D mode. I'm not sure of the hertz of the Evo 3D screen, but a 60hz monitor could display video at 60 frames per second, thus a 3D capable 120hz monitor can display 2D video @ 120fps or 3D video @ 60fps.

So the image quality will be the same for 2D and 3D video but fps may differ. That being said as along as 3D plays at about least 30fps you won't see motion blur, and anything over 60fps is just pointless lol. Hope this helps clarify

Autostereoscopic 3D is a generic term for glasses-free 3D. Evo 3D would definitely fall under that category. More specifically the EVO 3D uses a parallax barrier which is a specific implementation of autosteroscopic 3D

That is not completely correct. What you describe is the implementation used on TVs with the help of glasses. The problem that in a glasses free environment things don't work so nicely.

Think of it this way: You have a picture with 100 lines of resolution. Now on top of that picture you put the parallax barrier which is what separates what the left and right eye sees. This is where the problem comes in. The only way that this barrier can make each eye see something different is by somehow blocking parts of the picture for each eye. The way the most common implementation of the parallax barrier works is that it blocks half of the lines to the right eye and half of the lines to the left eye so that each eye sees alternating lines, i.e. the right eye sees even lines and left sees odd lines. This in effect is halving the viewing resolution.

The paper in the op describes another method where you wouldn't have resolution halving, but as we don't know the implementation in the Evo 3D we will have to wait and see if that's the case for it.

Key word in this paper - prototype.

After seeing the screen in 2D action, if the resolution is halved, I would be extremely surprised. It looked higher res than my EVO 4G right next to it.

Speaking of resolution, does anyone know if putting a screen protector on the Evo 3D will hamper or lessen the 3D viewing experience?

Never thought about that... it might. I don't think we will know until someone tests that on a real device.
