Android 65.438+0 billion pixels. Why does Apple still insist on 65.438+0.2 billion pixels?

How many pixels does a mobile phone need to take pictures? Why do major manufacturers widely use high-pixel sensors, and now Apple still insists on using12 million pixels?

I believe everyone who knows something about photography already knows it. The bottom layer is the first level to crush people. The "bottom" here refers to the image sensor. And its size is the key that affects the photo quality most, and the number of pixels is only a parameter of the sensor.

Under the same number of pixels, the larger the sensor size, the larger the single pixel area. On the other hand, the smaller the sensor size, the smaller the area of a single pixel. The area of a single pixel will affect the sensitivity, dynamic range and even calorific value of the sensor. It will eventually affect the imaging quality of our photos, so it is meaningless to abandon the size of the sensor to see how many pixels there are.

It is only one of the factors that determine the final imaging quality, not the higher the pixel, the better.

Every pixel of the baby can have enough space to bathe in the sun, and the photos taken naturally look good. However, in the very limited sensor size of mobile phones, more pixels means that the area of a single pixel must be sacrificed, which in turn affects the light sensitivity.

Photography is the art of exhausting light, and filming is of course very uncomfortable. Therefore, on high-pixel sensors, four-pixel integration technology is generally supported. Simply put, four pixels are combined into one pixel.

How can I put it? You can't just look at pixels. What you want to see depends on the algorithm adjustment of the software, the size of the sensor and the aperture size of the lens. Especially in the current situation, the hardware configuration of mobile phones is not much different.

The adjustment of software algorithms is very important, such as intelligent HDR on iPhoneXR XS.

In short, most manufacturers flaunt high pixels and highlight specific performance parameters. The greater significance lies in that the propaganda is more bluffing than it really sounds. So Apple12 million pixels is not much, but tens of thousands are still true, just use it.
