The ideal method of autostereoscopic television is that the pixel be viewed by the person situating there view so they see 3D.
Then the pixel through the grating moves left or right, for when the person shifts their position.
So as you might know, the pixels are affecting resolution for the more people see the picture.
So if the pixel shifts from left to right, there is a blank spot on the monitor not lit up and able to be lit up when the pixel shift onto it.
These blank spots can be treated like DLP checkerboard format –
” The processor in the TV interpolates the information in the “holes” from the surrounding pixels, which is twice the info available in side by side or top and bottom, which is also why the picture looks so good.” – Augerhandle
The pixel can’t shift left or right indefinitely, there is a limit to how far left or right it can shift.
How does the TV know to shift the pixel? The TV can have a camera that tracks the persons eyes once the person lets it know they see 3D fine.
So the TV needs a cue from the person that from that position they can see the 3D effect fine.
Then the TV adjust either left or right automatically as the camera tells it which way to move.
It may be that the pixels that aren’t in use but left blank ready for the pixel to shift cannot use interpolation to be lit up.
In this case the contrast would be affected by the unlit pixels.
Not only that but if the shift was 3 pixels either left or right each person would use 7 pixels per eye, not one – Even though only one picture was shown for each eye.
So how it would function is like a hockey goalie – the goalie follows the offensive shooter and stands inbetween the puck and the net, and when the shooter shoots the goals slide out towards the puck.
But for a tv, the camera would track the eyes position and light up the pixel so the eye see’s a 3D picture when it moves from it’s original position, and when it lights up the pixel the surrounding pixels the other pixels use interpolation this is so the contrast can increase and the percieved picture quality is better as a result.
