Where is the gap between the human eye and the camera?

The camera is made by imitating the principle of the human eye, but it cannot replace or replace the human eye, it can only be a flat record, and the eye sees a three-dimensional effect!

The gap between the human eye and the camera is actually mainly because the human eye can see closer, while the camera can see farther, and its color effect is better.

Because the human eye will be a little more sensitive to light, the camera, it can be adjusted to a state that the human eye cannot adjust.

A camera will never reach the sharpness of the human eye, because the pixels of the human eye are probably there. Billions or so.

The human eye can see a large distance, and the camera can also be clear, and the ability to see a small distance makes the camera more practical than a person.

The principle of imaging is much the same, but the camera retains the moment of the person

The human eye can see so much more than the camera.

The camera can magnify the human eye, but not.

What is the gap between the human eye and the camera? In fact, the human eye sees the reflection of the person, the camera is serious, and her gap is very large.

The human eye deceives people, and what we see is our own beauty.

The eyes of this class, but the camera is different from this camera, and the specific is also!

The gap between the human eye and the camera is in the end, the problem of accuracy.

What is the gap between the face and the camera? The human eye should not have a higher rate of recognition by the camera, and the human eye can only see in front of the eye, and even the resolution is higher than that of others.

This kind of brightness contrast between indoor and outdoor is technically called light ratio, and the larger the difference between light and dark, it is also called large light ratio. The mobile phone camera is limited by the photoreceptor.

piece size, the most afraid is the large light than the scene, the convex end of the micro single and single against this scene will be better. And those in film and television look very.

What is natural is actually created by indoor lighting.

Generally, when the camera encounters this situation, it can only be selected according to the setting type, indoor or outdoor** normal.

Regarding night, the human eye is equivalent to the automatic ISO setting of the camera, but this adaptation range will be greater than that of a mobile phone.

I saw a lot of things.

The last point of dark blue and light blue is the problem of the metering mechanism of the mobile phone. By default, the phone is in full-screen metering mode.

If the picture is brought to the ground, the mobile phone will judge that the ground is insufficient and add**. As a result, the sky is overexposed, and the blue turns to light blue. But if it's over.

Don't shoot the ground at all, only shoot the sky, and the general picture will be a little less exposed. If necessary, you can use your finger to tap the sky or the edge of the clouds and sky, and let the phone change to spot metering mode, which can be a good way to improve the situation. Now mobile phones seem to support spot metering**fine-tuning. Can.

to make good use of it.

People have pimples with poor growth, and the camera doesn't have eyes to see clearly, and it comes out when it's good.

The human eye must not be able to see clearly. But why the distant sunset under the background.

The gap between Lenovo and the camera is very large. The distance that the human eye and the camera can see is also different.

The 50x zoom captures the small characters 5 meters away, and the human eye will definitely not be able to see clearly. But why is it that the sky under the sunset in the distance is gorgeous and colorful to the human eye, while the camera shoots a muddy and muddy picture. Camera.

1. Aperture vs iris:

The aperture is used to control the amount of light entering the camera, that is, to control the ** degree, for example, the smaller the number of f2 8f3 8, the greater the amount of light entering; And the iris also controls the pupil and thus the amount of light entered, we can't look at the sun directly with our eyes, and the same is true for the camera.

The large amount of light coming in every minute can turn the camera into a dead machine, because the huge light will be directly exposed to the retina, burning out your retina, and the camera will also burn out the CCD.

So in bright light, we always involuntarily shrink our eyes, and when the camera turns on automatically, you will hear the sound of card card from time to time, and that is the sound of it automatically adjusting the aperture.

2. Shutter vs eyelids:

The shutter is to control the amount of light dwell time entering the sensor, the unit is time, generally expressed in this way as 1 201 5001 16000, and some can even reach 1 100001, the larger the denominator, the faster the shutter, you can quickly capture (capture) fast-moving objects.

Conversely, the slower the speed, the longer the light stays on the sensor, and the more trajectories are displayed, the more blurry it becomes, which is great for shooting traffic (streamers) and waterfalls at night.

It's the same with eyelids, try to shake your head or look at something that's moving fast, close your eyes for a second and think about what you see,, of course you're not seeing anything. Everyone's eyes have a limited ability to catch moving objects.

3. ISO (light sensitivity) VS retinal visual acuity:

ISO sensitivity, more powerful, 100, 500, 1600 years numeral indicates that the greater the sensitivity of light, at night, the greater the adjustability, the more powerful the sensitivity of light is felt, because this is not light, night nonsense, however, although at night it seems obvious to you, according to the situation is not clear.

Relative to the eye, it is the acuity of the retina, retinal cones are most sensitive during the day, rods work at night, but when we look at the stars at night, the more you notice a star, the less you can see. Only by looking around will you be able to see the stars you want to see.

This is because when we pay attention to an object at night, we use a pit (a pit) to detect light. However, the fossa has only pyramidal cells and is not as sensitive as rod cells at night, so the more you pay attention, the dimmer the light becomes. However, the camera doesn't have this dimple, so the sensitivity is getting higher and higher.

The similarities are both the principles of small hole imaging, the difference is that the camera uses a negative film or sensor to store the image, while the human eye transmits light signals to the brain through visual cells, thus forming an image in the brain.

Advantages of camera: The camera can capture the momentary action that the human eye cannot perceive, such as a lot of sports photography, and the wonderful moment when people are flying and jumping cannot be detected by the human eye; The camera itself is also a telescope and a microscope, whether it is telephoto photography or macro photography, it can take images that cannot be seen by the human eye; The ** of Kirigami captured by the camera is not only a reproduction of art, but also a record of history, no matter how strong people's memory is, it is impossible to remember the situation when they were just destroyed. Advantages of the human eye:

The dynamic range of color on the human eye is many orders of magnitude higher than that of a camera.

Summary. For example, the lens of the human eye is the vitreous, which is equivalent to a soft lens, which can instantly zoom and focus under the innervation of nerves, but this can only be reached by the lens of the latest modern technology. As another example, the aperture of the human eye is the pupil, an absolutely circular aperture, stepless retraction, and almost zero aberration.

Machinery may not be able to reach it in 100 years. For another example, the human eye's photosensitive medium is the retina, and the pixels are several orders of magnitude higher than those of CCD and film, and there are no noise grains, which is why the human eye is so demanding on image quality! Cameras are a product of human technology, and until now, the distance between cameras and the human eye was astronomical!

For example, the lens of the human eye is the vitreous, which is equivalent to a soft lens, which can instantly zoom and focus under the innervation of nerves, but this can only be reached by the lens of the latest modern technology. For another example, the aperture of the human eye is the pupil, an absolutely circular aperture, infinitely retracted, and the aberration is almost zero. Machinery may not be able to reach it in 100 years.

For another example, the photosensitive medium of the human eye is the retina, the pixels are several orders of magnitude higher than the CCD and film, and the grip is always noise-free, which is why the human eye is so demanding on image quality! The camera is a product of human technology, and so far, the distance between the camera and the human eye is still an astronomical distance!

I'm still a little confused, can you be more detailed?

It can never be compared, and there are some aspects of the advantages of the human eye that are impossible to achieve with technology! Its sensitivity and aperture are breathtaking!

Summary. Dear, the human eye is a fixed focal length lens, autofocus, the resolution is not high, the refresh rate is not high, the ISO is not high, and it all relies on a strong background to process various HDR and multiple stitching synthesis and calculate brain supplements.

I used my mobile phone to take pictures of the clouds in the morning in the morning, but the effect is not as good as the real Hu Huai I see in my eyes (the color of the clouds is more natural and real).

Pro,The human eye is a fixed focal length lens,With Sparrow Lu autofocus,The resolution is not high,The brush stupidity is not high,ISO is not high,It's all about a strong year of background processing of various HDRs and multiple splicing synthesis, as well as computing brain supplements。

My dear, the Canon camera takes pictures well. Hope it helps, thank you.

That is to say, many cameras can shoot the same as what we see** (especially clouds) This morning's mobile phone (not good) shoots ** is not as good as what you see, is there any camera recommendation.

My dear, the Canon camera is okay, the photo effect is good.

Dear, Canon, Nikon, Sony, Casio, Panasonic. These are the best, thank you.

Summary. Dear, <>

Hello, the teacher received the question: Is the camera comparable to the human eye, and the answer the teacher gave you is: <>

Hello dear, the camera is not as good as the human eye. <>

The human eye and the camera are actually a kind of existence that can capture everything in life. From a camera point of view, there is a problem of pixels. Therefore, the human eye will definitely have a higher pixel than the camera.

Hope it helps. <>

I hope it helps you. <>

Hello dear, the following is an extended information about your question, and Nengsenfeng provides you with reference <>

According to research, a normal person who is not nearsighted can have a vision of up to 150 million pixels, but today's cameras are only a few tens of millions of pixels. Generally, pixels are actually used to indicate the size of numbers, human eyes are hundreds of millions of pixels, and cameras are just a few thousand, and the units are already very different. Therefore, according to the comparison of numbers, it is clear at a glance, and the pixels of the human eye and even several times the pixels of the camera are more than grandiose.

Therefore, the human eye must be much clearer than the camera. Hope it helps, thank you for kissing <>
