What is the aftermath of vision, for example

It should be a visual persistence phenomenon.

Visual Retention Phenomenon (Visual Staying Phenomenon, Duration of Vision), also known as the "afterglow effect", was first proposed in 1824 by Peter Mark Roguert, a professor at the University of London, in his research report "The Visual Retention Phenomenon of Moving Objects".

When the human eye observes the scene, the light signal is transmitted to the brain nerves, and it takes a short period of time to pass through the end of the light, and the visual image does not disappear immediately.

Vision is actually imaged by the lens of the eye, and photoreceptor cells sense light and convert light signals.

Nerve currents that are transmitted back to the brain cause human vision. The photoreceptor cells rely on some photoreceptor pigments, and the formation of photoreceptor pigments takes a certain amount of time, which forms the mechanism of visual suspension.

What is visual retention? Put the ** quickly flip, and interesting scientific phenomena happen.

The phenomenon of visual persistence was first used by the Chinese, and the marquee lantern is the earliest visual retention application in historical records. In the Song Dynasty, there was a marquee lantern, which was called "horse riding lantern" at that time, and then the Frenchman Paul Rogue invented the photo disc in 1828, which is a disc that is threaded by a rope on both sides.

A bird is drawn on one side of the plate, and an empty cage is drawn on the other. When the disc rotates, the bird appears in the cage, which proves that when the eye sees a series of images, it retains one image at a time.

When an object is moving rapidly, when the image seen by the human eye disappears, the human eye can still retain the image of the human eye for about a second, which is called the phenomenon of visual persistence. It is a property that the human eye has. When an object is detected by the human eye, it is imaged on the retina and input into the human brain by the optic nerve to perceive the image of the object.

But when the object is removed, the optic nerve's impression of the object does not disappear immediately, but lasts for a second, and this property of the human eye is called "visual persistence of the eye".

Some people say yes, because the speed at which the movie changes frames is.

Refers to the human eye looking at some kind of moving object.

It feels good, but it's getting better.

Brother Superior is very good, I will add again, for example: at the moment when the lights go out, the scene in the room that still exists in our minds is a relatively common visual lingering phenomenon.

You can slow down the shutter speed, you can do it, the slower the longer, the current point-and-shoot machine can also shoot ah, that is, the ** time is long, your image sensor records the movement path of the light, you stretch the ** time, and then put it on the overpass, you will find that the cars on the road are all gone, all of them are rays.

This kind of camera is not ordinary, but it takes many images while the cigarette butt is moving, and then washes these images on the same negative, so there will be a moving effect, so it must be.

The camera also has a certain amount of time, for example, how much you let the candle move in it, how long the light will be.

All captured light will be captured within a ** time.

Visual Pollution In modern cities, there are two visual environments that are annoying: contentless vision and monoplasmic vision. The human eye is like a pair of automatic searchers, always in a state of searching, moving every two to three seconds, and grabbing something with each move. However, in an environment without a content vision, people have nothing to grasp the specific content, and as a result, there will be visual hunger.

Therefore, people who live in big cities usually have this feeling, their eyes obviously see a lot of things, but they don't seem to see anything, they are empty, which is a kind of pollution that the scenery in some cities brings to our vision. Elemental Vision Elemental vision refers to a visual environment in which a large number of the same components are concentrated. For example, in the city, combining the same things on a flat surface, paving the sidewalks in the same format, sticking a wall with tiles of the same color or designing all the same windows on the wall of a building, the same design, the same style, the same feeling, this is the monolithic vision.

Visual ecologists believe that this kind of cookie-cutter stuff can make people feel uncomfortable and even irritable. This is because human nerve cells work according to their own laws.

To be is to be perceived, this is the famous quote of the famous subjective idealist philosopher Berkeley. The meaning of this sentence is that the material world we perceive is actually made up of various senses. To give a popular example, a person has been placed in a laboratory instrument since birth, and he is deprived of hearing, smell, taste, touch, sight.

Then input the corresponding sensations directly into his brain, such as the image of the beach and the sea, the sound of the rolling waves, the smell of the sea breeze, and the soft feeling of stepping on the sand. Then in this man's world, he is on the seaside.

Optical illusion?

Movies are a good example of this... With the effect of "visual retention", the film deteriorates quickly, and the afterimage of the last time has not been eliminated, and the next time it appears again, so there is a dynamic effect

Just right, it came in handy. Come to my space and take a look at the "Deception Picture" in the log
