What is the phenomenon of black bars from right to left that appear when a mobile phone shoots a com

If there is a shadow when taking photos on your phone, it is recommended that you try it:

1.Try taking pictures with your own camera.

2.Change the location with better lighting to take a picture and try it.

3.Clear Camera Data: Settings - (General More) - Application Manager - All - Camera - Clear Data (Please back up the **, ** files in the album in advance to avoid data loss).

4.An attempt to uninstall recently installed software.

5.If your phone supports ** upgrade, please go to Settings - (General More) - About Device (About Phone) - Software Update (System Update) - Update (Please back up the data in your phone before upgrading).

6.If there is still a shadow on the photo interface, please back up the data in your phone, and then restore the factory settings (Settings - Reset Privacy - Personal - Factory Reset).

If the problem persists, please bring the purchase invoice, repair card and machine to the Samsung service center for professional after-sales engineers to help test.

We recommend that you perform the following steps:

1.Turn your phone on and off again.

2.Go to Phone Settings - Apps - Tap Camera - Storage - Clear Data.

3.Back up your phone's data (**book, SMS messages, multi** data, etc.) and restore your phone to factory settings.

If the problem persists, it is recommended to send the phone to the nearest service center for testing.

Normally, it should be caused by the difference in the refresh rate of the mobile phone camera and the computer screen, and the screen of the OLED class will also have such a phenomenon when recording the OLED screen with the mobile phone.

Do you know why there are always streaks on the computer or TV screen taken by your phone?

Do you know why there are always streaks on the computer or TV screen taken by your phone?

The computer screen and the TV are the same, they are all emitted by the picture tube, and the luminous principle is to send a light through an electricity, China uses 50 hertz, that is, 50 flashes a second, and the naked eye is indistinguishable, when shooting with a mobile phone, because the mobile phone pixel is not so high, so it will cause such a situation, to explain, do not think that five million pixels are very high, this is only relative to the mobile phone.

This problem is the same as cameras and camcorders. It's all signal interference, so it will cause the phenomenon of clauses on the computer screen. The same TV has the same effect.

= =！It's the refresh rate of the CRT monitor. Because the mobile phone camera is several times more sensitive to catching dynamic things than the human eye, you can see the refresh rate of the computer on the phone, so there is a black stripe! Normal wow.

Your monitor must be a CRT monitor, which is not the kind of liquid crystal, and black streaks are normal, and that's the reason for the low field frequency of the display, and the liquid crystal display doesn't have that phenomenon.

Oh, that's not a phone problem, it's a computer flashing, it's normal. I don't know the specifics.

Moiré is a unique phenomenon when taking pictures with digital cameras.

When shooting bright areas, dense streaks may appear.

The brightness of the computer screen is relatively high, so shooting the screen with the camera sometimes shows moiré patterns.

==！It's the refresh rate of the CRT monitor. Because the mobile phone camera is several times more sensitive to catching dynamic things than the human eye, you can see the refresh rate of the computer on the phone, so there is a black stripe! Normal wow.

That's because the screen of your computer has to be refreshed, constantly brushing from the bottom to the top, you must be using a CRT monitor, which is the kind of very large, not LCD, and you generally do not have such a problem when you take LCD!

Because your monitor isn't LCD, the frame rate is wrong, it's normal, and it's the same when you shoot a TV.

Do you know why there are always streaks on the computer or TV screen taken by your phone?

The LCD doesn't have your home is flat.

The computer screen is not good, the refresh rate cannot be distinguished by the naked eye, and the pixels of the mobile phone camera are not good, and you can see it when you shoot it.

The refresh rate of the computer monitor is caused by the hertz of the computer is 60, and the frame rate of the mobile phone camera is not enough, and the frame rate of the mobile phone camera cannot reach this value.

So that's it.

The computer flashes screen, which uses alternating current, so it will flash, and the human eye has a visual stay, but cannot be observed.

That's caused by the flickering screen of the display.,The human eye reacts slowly.,Can't see it.,The display is not good for mobile phone photos, and there will be the kind of situation you said.,You try the old-fashioned TV again.,The stripes are more obvious.。

In fact, these "water ripples" are generated because the screen refresh rate is lower than the shutter speed of the mobile phone, which is what we often call the hertz (Hz) of the screen. The refresh rate of our usual old TVs is generally 50Hz, and the newer ones are 60Hz, and most of the LCD monitors we use now are also defaulted to 60Hz.

For the screen is not always glowing, but will be refreshed every once in a while, for example, the 50Hz, which means that it is refreshed 50 times per second, and the human eye is completely unaware of any flickering on the screen. When the mobile phone shoots the screen, most of them will also have a relatively fast shutter speed. When the shutter speed is faster than the refresh rate, it captures the screen refresh process that we can't see with the naked eye, which creates "water ripples".

To get rid of water ripples, it's as simple as slowing down the shutter speed. If you're using a DSLR or a digital camera with M stops, you can control the water ripple by adjusting the shutter speed. However, on mobile phones, most mobile phones do not support adjusting the shutter speed.

So when shooting the screen, you really have to shoot a completely water-free **, it is still more difficult for mobile phones, and now some mobile phones will have an option to "reduce flicker", which will adjust 50Hz Hz or automatic settings. This setting was added specifically for this situation, but it doesn't really work too much. Or you can look for third-party app support.

Do you know why there are always streaks on the computer or TV screen taken by your phone?

1. Try replacing it with a battery with sufficient power. It could be that your battery is low and the camera is not turning on.

2. Change the settings. It may be that you turned off the LCD display during your last photo shoot and the camera remembered. You can press the playback button, and if the camera can play back**, it means that the display is turned off, just change the setting.

3. If the above two tests do not solve the problem, then there may be a problem with the display, and you need to go to the Sony camera maintenance department to check it.

That's because of the problem with the image refresh rate. Our naked eyes can't see the refresh rate of images from TVs and computers, but mobile phones and digital cameras can capture them, so when we look at computers and TVs through our phones and cameras, we see a lot of scrolling streaks.

Electronic device screens have refresh rates, such as 50Hz, 60Hz

The human eye can't see it, but the CCD of the camera can capture it... Those small horizontal lines are scanlines.

Due to the angle and the distortion of the lens itself, it looks like a distorted line.

Actually, the reason is very simple! For example, if you draw a row of vertical lines on two sheets of transparent plastic paper, one at the top and one at the bottom every 1 mm, it is easy to see that the vertical lines overlap every 11 mm. Near the overlapping position of the thin lines, the exposed gap is large and appears bright; However, near the position where the thin lines do not overlap, the exposed gap is small, and it appears gray.

The result is an 11 mm distribution of light and dark, which appears as a thicker stripe with greater spacing, which is easily perceived by the eye, as shown in Figure 1. When there is a certain angle between the two, the stripes are tilted, which produces a ripple vision.

Most of the LCD monitors we use today are 60Hz by default. And because the screen is not emitting all the time, but will be refreshed every once in a while, for example, that 60Hz, which means 60 refreshes per second, the human eye is completely unaware of any flickering on the screen.

When the mobile phone shoots the screen, most of them will also have a relatively fast shutter speed. When the shutter speed is faster than the refresh rate, the screen refresh process can be captured that is invisible to the naked eye, which creates "streaks".

It is caused by the imaging of the TV, because the TV is constantly switching pictures to achieve the dynamic effect, the interval of switching is not felt by the human eye, and the same principle is achieved in this way The dynamic picture of the mobile phone is also achieved in this way, but when you use the mobile phone to shoot the TV picture, the interval between the two switching pictures will form an interference, although the human eye can not feel it, but the machine can see it, so when the mobile phone shoots the TV picture, interference fringes will be formed.

This phenomenon is because of the problem of the refresh rate of the image of the TV and the computer, our naked eye cannot see the image refresh rate of the TV and the computer because of the delay of the light, but the mobile phone and digital camera can capture it, so when we look at the computer and TV through the mobile phone and the camera, we will see a lot of scrolling stripes.

Television images are made up of frame-by-frame images, and when you shoot with your phone, they leave a frame, which forms a black streak.

The machine slaps the machine, and when you say hello to each other, you can only communicate with stripes

The frequency of the TV screen is a problem, which cannot be seen by the human eye, but can be captured by the mobile phone.

The frame rate of the mobile phone and the TV screen are not the same, so it will be like this.

This is the case when the camera refresh rate is not a multiple of the TV refresh rate.

There will be interference when the mobile phone shoots the TV screen.

caused by the influence of the angle of the phone and the change of ambient light.

It is because of the refresh rate of the TV image, which is not visible to the human eye.

When you take a picture of a computer or a TV screen with your phone, sometimes you get some ripples, some vertical, some horizontal, and even other shapes that are clear about our phone pixels.

I don't know if you've ever been in this situation. When you take a picture of your computer or TV screen with your phone, sometimes there are some ripples, some are vertical, some are horizontal, and some are even other shapes. They change when you zoom in or out.

They're ugly. What's wrong? This is because when you shoot a computer with a mobile phone, both things have radiation, and then there is a reaction, and ripples appear

So, what are moiré stripes? Moiré fringes are interference images produced by two or more sets of different fringes superimposed on two or more similar spatial frequencies. Moiré fringes are the visual result of two lines interfering at a certain frequency.

When the human eye can't tell the difference between these two lines or two objects, it actually magnifies the difference between the edges. Technically, it is the visual result of two objects or two stripes interfering with each other at a constant angle and frequency. When these issues cannot be discerned with the naked eye, there are three differences between the regulations.

In short, it's the interaction between a computer display, a mobile phone display, and a mobile phone camera.

Why does the camera ripple when it shoots a computer screen? After reading it, I finally understood.

This is because when you shoot a computer with a mobile phone, both things have radiation, and then there is a reaction, and ripples appear

There are two reasons for this ripple, one is due to the screen refresh rate of the mobile phone and computer monitor is out of sync, and the other is due to the interference of moiré streaks. This is a normal phenomenon.

There are two reasons for the ripple of the computer screen when the mobile phone shoots the computer, one is due to the screen refresh rate of the mobile phone and the computer monitor is not synchronized, and the other is due to the interference of moiré streaks. This is a normal phenomenon.

I think it's because of the settings of the screen.

Because it's a problem with the light, and it's a problem with the phone camera.
