Is the Picture Taken by a 100 Million Pixel Mobile Phone Really Better Than That Taken by an Ordinar

First of all, we should understand one thing, what is a pixel.

All the pictures we see are actually composed of "color dots", and each individual color dot is what we often call "pixel". A picture is composed of 1 million color dots, and the pixel of the picture is 1 million.

Usually, the cell phone pixels we touch refer to the single electronic components that sense light and image on the cell phone sensor. For example, a camera with 10 million light-sensitive devices is a 10 million pixel camera, a camera with 64 million light-sensitive devices is 64 million pixels, and so on.

The higher the pixel, the larger the size of the photo, and there is more room for post-processing. In addition, the size of pixels is not fixed, and its arrangement order is not unique, such as common RGB sub-pixel arrangement, RGBW technology arrangement, pentile arrangement, etc. the change of this arrangement can also improve the picture resolution and photographing experience, but it is more important to determine the size of photosensitive elements.

Theoretically, the larger the pixel size, the better the imaging

The combination of photosensitive elements and pixels is a good mobile phone.

The image quality depends on the number of photons captured by the photosensitive element. The larger the photosensitive element, the more photons captured, the better the photosensitive performance, and the more delicate the photos taken. Therefore, the focus is not only high pixels, but also a big bottom.

Referring to the figure above, the larger the pixel size, the better the noise and dynamic range of the image can be controlled, and the influence of the dispersion circle is less. Apple has been using 800W low pixels before. The big reason is to maintain a large pixel size.

Under the bottom blessing, the one with high pixels wins the world.

In addition to the two, it is the various adjustments of mobile phone manufacturers about their products. Therefore, some people say that Apple's profit is higher than that of domestic mobile phones. After all, iPhone has a strong dependence on software optimization, which weakens the cost of hardware.

Therefore, whether Apple, Samsung or domestic mobile phones, they are also very excellent products. The biggest difference is whether the hardware is upgraded or the software is optimized. Did you learn?
