Basically, yes. Our eyes capture the light that goes into them at 24 frames per second (please correct me if I goofed on that) and the image is upside down.

Our brains turn those images upright, and it also fills in the blanks. The brain basically guesses what’s going on between the frames. It’s highly adapt at pattern recognition and estimation.

My favorite example of this is our nose. Look at you nose. You can look down and see it a little, and you can close one eye and see more of it. It’s right there in the bottom center of our view, but you don’t see it at all everyday.

That’s because it’s always there, and your brain filters it out. The pattern of our nose being there doesn’t change, so your brain just ignores it unless you want to intentionally see it. You can extrapolate that to everything else. Most things the brain expects to see, and does see through our eyes, is kind of ignored. It’s there, but it’s not as important as say, anything that’s moving.

Also, and this is fun to think about, we don’t even see everything. The color spectrum is far wider than what our eyes can recognize. There are animals, sea life and insects that can see much much more than we can.

But to answer more directly, you are right, the brain does crazy heavy lifting for all of our senses, not just sight. Our reality is confined to what our bodies can decifer from the world through our five senses.
