Re: discussion on the various possible theories that may be applicable to LrL's
Well, I can tell you that it doesn't work like a TV.
A TV works similar to an oscilloscope. The camera scans, from left to right, a tiny dot area. For black and white, the intensity of light observed by the TV camera, on that tiny scan line varies as it moves from left to right. When the camera has finished scanning one line, at a constant speed, the aim of the pickup is returned back to the left side very quickly, a little lower down, and it starts scanning across all over again, at the constant scan speed.
When all the lines have been scanned, it quickly goes to the top, and starts scanning the next frame.
Actually, the current technology goes from line number one to line number three, then five, then seven, and so forth, on the first pass; then scans lines two, four, and six, and so forth, on the next pass. So it really takes two passes of the scene to make one frame. This is called interlaced frames.
Then it starts on the next frame. DVD's have 29.97 frames per second. TV is a little lower speed than that. Non-interlaced frames technology is called progressive scanning.
But, basically, television is based on a scanning system.
If human sight were based on a scanning type technology, it would need to be many times faster than the best grade of electronic video, because there is
never any flicker in eyesight.
I knew a guy that, standing next to me, could which side of a branch a .22 bullet flew. I knew, because I was using a scope. I didn't even think to look for the bullet, but after I fired a few rounds, he told me where they all went. I was cutting a thin branch, and I started a little away from the branch, and rapid fired across the branch to cut it. He then told me which side I had started on! He acted like he thought everyone could see it. Maybe they can, and I never tried. Anyway, it did not flicker, even at that speed. He could see it during it's entire flight.
Human eyeballs don't have the circuitry for scanning type of video, anyway.
On the other hand, if there is no scanning, there would need to be a signal line from every single rod
and cone in each eyeball. But there isn't that, either. Also with this theory, there would have to be someplace, presumeably in the brain, where all these signal lines are converted into a picture, but that circuitry isn't to be found, either.
And, even more importantly, if all that circuitry somehow did exist, where is the little screen that it is displayed on, and, even better,
who is watching that screen?
