Under the bombardment of commercial advertising, there has always been a misunderstanding that leaves a mark on consumers' minds. In fact, it is just a gimmick for all businesses, that is, the higher the pixel of the camera, the better.

In fact, this statement is not correct; There are many factors that determine the imaging quality of a camera. The number of pixels does not determine the image definition, or even the higher the better. Pixels are related to definition, but relatively speaking, they are not absolute. In fact, besides the pixel level, there are other factors that affect the image quality, such as sensors, lenses and software processing technology.

Resolution, also known as resolution and resolution. Resolution refers to the measure of image clarity or density. Simply put, the resolution of an image depends on the resolution of the image.

The separation rate can be classified from the display resolution and the image resolution. Image resolution is the number of pixels contained in a unit inch. The display resolution is the precision of the screen image, which refers to how many pixels the display can display. Under certain circumstances, the smaller the display screen, the clearer the image, but when the display screen size is fixed, the higher the display resolution, the clearer the image.

Personal opinion, for reference only! Share some photos taken by mobile phone.

Some people do confuse these two differences and concepts.

The pixel of a mobile phone camera is the standard for recording the quality of photos taken by the camera. The higher the pixel, the more digital signals recorded, the clearer.

For example, the total pixel of Huawei's mobile phone camera reaches 40 million, and the telephoto pixel reaches 8 million, in order to improve the definition of photos.

The screen resolution of Huawei's mobile phone is 1920* 1080, which belongs to high-definition display. There is no need to make efforts to improve the screen resolution. If it is, the selling price is also high.

The resolution of mobile phone screen is the function of showing the memory of mobile phone for you to watch. The two are not the same thing. The mobile phone screen is a TV.

If the TV station plays high-definition signals, your TV set is not a high-definition screen, but it can also be watched, but the definition is not high-definition.

This involves the cost and technical research of mobile phone manufacturers. Under normal circumstances, it is not necessary for the screen resolution of mobile phones to exceed the photo pixels.

The pixels taken by a mobile phone refer to the pixels of the pictures taken by the camera of the mobile phone. If the camera of the mobile phone can take 4K pictures, it means that the mobile phone is equipped with a 4K camera, just like Xiaomi 10 mobile phone, which can discharge 100 million pixels of photos. The pixels taken by the mobile phone are only related to the camera he carries.

If you use a very old Nokia phone, the screen is about the size of a fingernail, but as long as it is equipped with a 100-megapixel camera, you can still take 100-megapixel photos.

The screen resolution of a mobile phone refers to the number of pixels on the screen of the mobile phone. Take Xiaomi 10 mobile phone for example, its resolution is 2340x 1080, that is, there are 1080 pixels horizontally and 2340 pixels vertically, so the total number of pixels is 2340x10. But its camera can take pictures of 100 million pixels. As you can see from here, the two have nothing to do at all.

You can imagine a camera specially used for shooting. Their screen is smaller, but they can take pictures with great resolution. Even if the camera doesn't have a screen, it doesn't affect it to take pictures, and so does the mobile phone.

There has always been a question, what is the relationship between mobile phone camera pixels and screen resolution?

The subject thinks too much. The pixel of the mobile phone camera has nothing to do with the screen resolution. For example, if you open a bag of rice, what does the rice you can see have to do with how much rice is in the bag?

The screen resolution of the mobile phone is only about the fineness of the photo, and it has nothing to do with how many pixels the photo can take.

If you insist on the relationship, it can only be that the higher the screen resolution, the more detailed and detailed the photos are.

Simply speaking, the camera pixel refers to the amount of information that the mobile phone camera can collect, while the screen resolution refers to the amount of information that your mobile phone display can display. There is no direct relationship between the two. Generally, the camera pixel is far beyond the screen resolution. For example, the pixel of your mobile phone is 8000 (for example, it is easy to calculate, not so low), which means that the picture you take is made up of 8000 luminous points, which are all arrays of 20 point light sources. The most intuitive pixel point is the LED screen, on which you can intuitively see the image text composed of some light sources. And suppose that the screen resolution of your mobile phone is 8000, then 8000 point light sources collected by your camera will be displayed on the screen in an array of 20*20. Suppose that your screen resolution is 1000, then when you show the 8000-pixel photo of your camera, you will combine two adjacent points into one point to show it. At this time, your eyes are just like seeing things from a distance. Blur some details to see a rough outline, and then you want to see smaller details. At this time, you will enlarge the picture, and you can see all the information of 8000 points collected by your camera by enlarging the picture twice. At this time, your screen can only show the information of 1000 points, so you need to drag left and right to see the information of other points. To sum up the relationship between camera pixels and screen resolution, the higher the pixel of your mobile phone, the more details you can capture, and the higher the screen resolution, the higher the details you can show. However, at this stage, the resolution of mobile phone screen has reached a very high level. If we improve the resolution on a limited small screen, we will reduce the pixel size, because the human eye can't recognize smaller pixels, so it is not meaningful to continue to improve the resolution. But the camera is different. The higher the pixel of the camera, the real effect it brings. For example, if you shoot a distant object, your naked eye can only see a rough outline. However, as long as the camera can record more detailed information, it can constantly zoom in to show those details. Of course, there will be an extra indicator here, that is, zooming, which is to be able to project distant images into the camera. This is the recent propaganda of various zoom cameras shooting at a distance.

Hello, Pixel) = size (Inch) times resolution (PPI).

1, the higher the resolution of the image, the clearer the picture looks;

2. The resolution of the image depends on the pixel and size of the image. A picture with a high pixel and a small size has a high resolution and a clearer picture.

3. The higher the pixels of an image, it doesn't mean that the picture looks clearer, but it can display a picture with a larger size under the condition of the same definition (resolution).

Pixel: Each picture is composed of many color points, and each color point is called a pixel.

Resolution: refers to the number of items expressed or intercepted in unit length. What we usually call the resolution of the camera refers to the image resolution, which means the number of pixels per inch of the image, and the unit is pixels per inch (PPI). The higher the image resolution, the higher the pixel density and the clearer the image.

The higher the pixel of the mobile phone camera, the higher the resolution of the photo. Pixels are units of resolution. A simple understanding of ordinary definition, high definition and ultra-clear means the pixel height, the higher the pixel, the clearer the resolution.

PIXEL pixel, or PX

Technically speaking, the more pixels in a unit area, the greater the resolution of the display. A pixel can be understood as a point, and there are generally three sub-pixels above this point, representing three colors respectively. Rgb(red,green,blue) is the three primary colors in junior high school physics: red, green and blue. In rgb, colors are represented by brightness values, which range from 0 to 255, with 0 being the darkest and 255 being the brightest. For example: black: rgb(0,0,0), white: rgb(255,255,255). It can also be expressed in 16: white: #000, black: #FFF.

I'm glad to answer your question … I hope my answer will help you. Thanks to the authorities

First of all, the display screen is not the same as the camera. The display screen is used for displaying, and the camera is used for taking pictures. The pixels of the camera are all higher than the display screen, so after taking pictures, a large pixel photo is displayed on a small display screen. You don't have to worry that the small display screen can't display it, because the mobile phone algorithm can combine several pixels into one pixel and display it on the screen.

For example, in a mobile phone, the display pixel is 384,000, and the camera is 3 million (that is, the photos you took according to 2048× 1536), so his so-called maximum resolution is 3 million pixels. 3 million can be displayed on a screen with 480,000 pixels.

After the mobile phone shooting is completed, most people look at it with their mobile phone screen, thinking that this is the final effect of the camera. In fact, a large part of the display effect is related to the screen. For example, the iphone looks particularly good because of its good screen effect. In fact, if you want to compare the capabilities of the camera, you need to import photos of each mobile phone to the same computer to compare them.

If the display screen of a high-pixel camera is not good, or the camera itself has no optimization algorithm (no saturation increase, etc.), or the camera supply is not good, this can affect the imaging effect. Pixels are not everything, in fact, 8 million mobile phones are enough, because the core components of mobile phone camera are so big, and it doesn't make much sense to have too many pixels.

16 million color problem, which is more complicated. Don't expect you to understand everything. You know that our mobile phone is a digital system, and any color is a combination of red, green and blue. In order to show realistic colors, we hope that the more red, green and blue colors from the lightest (colorless) to the completely saturated, the better. Therefore, when we design the display screen, we constantly increase the grade, with the lowest monochrome, followed by 256 colors, 4096 colors, 65536 colors, 260,000 colors and16 million colors. Until16 million colors reach the so-called true color. Its display range is also difficult for the eyes to distinguish the difference between its color and natural color.
