In today s world of photography, how far is a mobile phone from a camera?

Mobile phones and cameras were originally two product lines of "well water does not interfere with river water", but now the contradiction between the two has been infinitely magnified. On the one hand, the shooting performance of mobile phones is getting stronger and stronger, and the overall camera is getting cheaper and cheaper, and the target users of the two sides have begun to overlap;

On the other hand, many mobile phone manufacturers and ** will always compare cameras intentionally or unintentionally when promoting products, and this official "war" approach has undoubtedly played a role in fueling the flames. Take a look at the latest phones: the 40-megapixel Huawei P30 Pro, the 48-megapixel OPPO Reno, the 64-megapixel Redmi Note 8 Pro ......Looking at the current camera, the Sony A7R4 has 61 million pixels, which is already the highest level of full-frame, and the Canon EOS M6 Mark II "only" has 32.5 million pixels, which is already the best in APS-C format.

Speaking of pixels alone, the phone seems to have won, <>

However, the "number of pixels" only determines the resolution of the output, and the sensor area and the size of a single pixel are the key factors that affect the image quality. The sensor area of the above-mentioned mobile phone has not reached the level of 1 inch, and 1 inch is more than the APS-C commonly used on the SLR mirrorless, how much is there a gap between the full frame, please see the sensor area itself is small, and forcibly squeezing in more pixels will only further compress the single pixel size of the mobile phone, reducing the photosensitive area of each pixel point, <>

This is very fatal to the detail clarity and low-light noise control. For example,The same is the 60 million level,Redmi Note 8 ProSingle pixel size is,Sony A7R4It is,This is only one-sided,In terms of areaA7R4As a camera,Its single pixel area is about 25 times larger than that of a mobile phone with the same pixel,The imaging quality of the two is not at the same level at all。

Many mobile phone manufacturers and ** will always compare cameras intentionally or unintentionally when promoting products, and this official "war" approach has undoubtedly played a role in fueling the flames.

However, the "number of pixels" only determines the resolution of the output, and the sensor area reduces the sensitive area of each pixel.

The accuracy of the poor professional camera equipment, Ken can still be some way away.

The sensor area and the size of a single pixel are the key factors that affect the image quality.

The size of a single pixel is the key factor that affects image quality.

In fact, as the light blue air said, the principle is the same.

But why is a phone a phone and a camera a camera? In fact, the structure of some parts is simplified due to the size relationship of the mobile phone, which also leads to a decrease in the photographic performance.

The sensor is different.

This is the biggest flaw of mobile phones and cameras. What is an image sensor? In layman's terms, it means that the digital camera captures the original light signal and converts the light into an electric charge and is read by the camera (or mobile phone).

Due to the size of mobile phones, the image sensor is usually very small and small, and the circuit is much denser than the camera's image sensor, so interference is inevitable, so the image quality is reduced. So even if it is a mobile phone and a camera with the same pixels, the image quality cannot be compared. The second picture is a comparison of the size of the frame, and the smallest one in it is the size represented by the iPhone4.

The Nikon DX is the CMOS size of most entry-level SLRs, the smaller APS-C is the CMOS size of Canon's entry-level SLR, the outermost gray is the CMOS size of Nikon Canon's full-frame SLR, which is also the format size of standard 35mm film, and the larger ones are the medium-format and large-format cameras that are rarely seen in daily life.

Most of the optical parts in aperture mobile phones are very simple, and it is also because of the volume constraints of mobile phones, and it is impossible to use special glass of various colors for glass. Aperture is one of them. The aperture of mobile phones is mostly constant and unadjustable, and even if the f-number of the aperture is the same as the f-number of the camera lens, the difference in light transmission is huge, so the mobile phone is a loss.

In fact, the shutter is rarely mentioned, and not many people can know about this flaw. Again, because of the size of the mobile phone, most mobile phones do not have a mechanical shutter structure, and all the shutters are electronically controlled shutters, so the various shortcomings of the electronic shutter are all reflected in the mobile phone.

Image processing. Whether it's a camera or a mobile phone, there will be a part for image processing. Since this part is not a hardware problem (the hardware performance of the mobile phone is more than that of the SLR), it depends on the algorithm skills of the manufacturer, and the mobile phone manufacturer is not professional in this aspect, so the picture that comes out is definitely not as good as the picture from the professional camera manufacturer.

The above point is only for most mobile phones, for the Nokia 808 and Panasonic CM1, these phones have to be said separately, because they really have a camera directly tucked into the phone.

**Mode and sensor sensitivity. **Processing speeds can also vary worlds as well.

The principle is the same, except that a professional digital camera can accurately control various parameters while a mobile phone cannot. Then there is the use of digital cameras specially designed to take pictures, which is easier to operate.

The mobile phone hits the ** camera to take pictures of the professional must be better than the amateur.

Pixels, color reproduction, and portability are all different, depending on how you choose

A phone that can't do it with a camera can do.
