how many pictures does a human eye capture in a lifetime?

Answer 1

(None, they are video!) ...Just as a digital camera lens doesn't capture a pic (it's the memory that does)... the same thing applies with humans. Our brains record images, and then save more over them. Quick! What did that street-sign or red-light (last week) look like -- see? - you record images that were important for that second, and then override them to the point where you forget details of that image. So, the answer is actually "infiniti" because there's unlimited parts of moving pictures, etc. that are sent in through the eyeballs, stereoscopically and in full-motion - by the millions per day. But they aren't true "pictures" but memories retained, with visual recall.

Answer 2

Sorry, I get where you're coming from and it's a nice romantic idea; but you can't consider the human eye as capturing any 'pictures' at all. It doesn't even work like a video camera (which some people seem to believe).

Pictures implies that an image is fixed on the retina and then replaced by another one: either consecutively as in film or cinema photography, or scanned as in digital photography and video.

The eye just doesn't work like that. The incoming light is continuously changing in intensity and colour over the retinal surface in such as way as to make any 'picture' comparison meaningless.
Even if you sit and stare fixedly at something your eye is registering continually varying light patterns.

You would have to artificially 'chop up' the incoming light into 'images' in order to answer your question. To do this would mean fitting a shutter of greater activity and precision than your eyelids. Methinks that you would very soon suffer from vertiginous symptoms.

Nice try, but no cigar this time.

We know that the minimum amount of pictures per second required for us to see them as "movement" is 25 frames/second, hence movement on TV is this rate. If we say that a human lives to age 80, which is 80x365.25x24x60x60 to give 2524608000 seconds in the human lifetime, and we say that a human is awake 16 hours a day, which is a ratio of 16 hours awake to 8 hours sleeping, we are only seeing pictures for 16 24ths of the time, or 1683072000 seconds of sight per lifetime. Assuming that we were only to see at 25fps, then we would see 1683072000x25 pictures in a lifetime, or

42,076,800,000 pictures in total over a full lifetime.
[Forty two billion seventy six million eight hundred thousand]

Unless you go blind. And of course as the others point out, we don't see in separate pictures, so this is just hypothetical - that is to say if we were to break up everything we see into 25 still images per second, rather than see it in the "true" moving way we do.

As other have said, the human eye does not capture discrete pictures. In fact, the human eye doesn't, in general, capture any pictures, in the way that we normally think. The eye, itself, is really just a lens. The processing unit in our bodies is the brain, which picks up PARTS of the image, but not the image as a picture. Which part depends on various things.

So, if you could take a discrete snapshot of what he brain receives and processes, it wouldn't be a picture, but components on the picture.

Answer 5

the human can capture as many pictures as he or she wants to. You can stare at a single picture your whole lifetime and just remember that single picture if you want to

Answer 6

Great question. Unfortunately it gets into how the brain works, and we're not completely clear on that yet.
I think what you're referring to is how certain "pictures" or "scenes" stick in our memory.
I'm 72 and can (not very sharply) remember several "scenes" from my pre-school years.
I also remember math formulas from high school physics class that I haven't thought about for years.
I also remember the new person I met at choir practice last night, but don't remember a thing about driving home.
I can also remember looking at a book on the shelf above me that I glanced at several minutes ago. I don't expect these last memories to stick around very long.

As you can guess, our memories (pictures) seem pretty much unlimited, but - unless reinforced by a dramatic occurrence, or great significance or by sheer repetition, they fade.
My mother died about 6 years ago. I can recall her face by remembering a photo of her or a particularly fond instance, but often -sadly - I have a hard time picturing her in my mind.

Answer 7

eye does not capture any picture. It only see , and transfer the data to brain. Brain accordingly places it in suitable slots, so that you can recall it, when required. Example, you visit a really beautiful place, your eye capture what all you see. Next day when are explaining the beauty of that place to a friend, data stored in brain will recall / open. So that you can explain, in detail what exactly you saw. Once you complete, it goes back to to its place, you can recall it again.

Answer 8

They weren't. As you observe, the wiring of the human eye, unlike that for many different species, is on the incorrect side. that's an artifact of evolution, and the unfavourable outcomes of this actual botch weren't unfavourable adequate to maintain the species from further progression.
