According to Professor Roger Clark, a scientist and photographer, the resolution of our eyes is 576 megapixels. What a huge number compared to the 12 megapixel camera on the iPhone7. But in fact, what does that number mean?
From digital cameras, digital SLRs to flat-panel TVs, people are always trying to choose the devices that deliver the clearest, smoother, smoother images. But advances in technology, particularly in the field of display, have given us a new question: when does our eye no longer recognize what is real?
When we know how many megapixels the human eye has, maybe we can answer that question.
Resolution of 576 megapixels means a display can give us the image so sharp and clear that we cannot distinguish each pixel, and we have to “cram” how enough 576 million pixels into your current vision.
To get this huge number, Dr. Clark said that the sharpness should be uniform at every point of view of the eye. This means when you move your eyes, the sharpness and the pixels you see do not change. But usually when you look at something, the resolution you see will be reduced by 5-15 megapixels.
Why? People are not perfect and my eyes, too, are the faults of the eyes are things that a camera captures normal images are not acceptable.
For example, you can only see high resolution in a very small area between your visions, the area called the visual pits. The eye has a certain blindness, the location on the retina is where the optic nerve enters the eyeball but not yet broken into small branches with light-sensitive cells. It is the movement of the eye from one point to the other in order to correct the faulty eye-contact, when it does not see the whole picture at first.
In fact, the question for the resolution of our eyes is a false question. The human eye is not the same as the camera lens, capturing the scene that is seen and stored in the brain.
They are like detectives who scrutinize, gather information from the surrounding environment and then put it into the processing brain, turning it into a complete image.
Although there are high enough resolutions that our eyes do not know “what is real, what is real,” but when talking about daily eye use, the concept of “megapixel” is not enough.
