Why the pixels of automatic cameras are not high?

Why are the pixels of the camera so low?

Some friends have such questions "

", the editor of Gome is happy to answer your question about the low pixels of the camera.

Because of the current video system, the resolution of 1080p full HD is 1920x1080, in other words, it is about 2 million pixels

The difference between the CCD of the camera and the CCD of the camera:

The main difference is speed. The camera's CCD pays more attention to fast sampling. The sampling quality may not be as good as that of the camera, but it has to be fast in order to achieve continuous effects, while the camera prefers instantaneous sampling quality. .Camera photography, I am not specialized in the art, I can take pictures but the effect is not as good as that of a camera.

The number of pixels of the camera does not have high requirements, the key is:

1. Continuous sampling The heat generation during operation

2. The ability to read and write quickly and accuracy

The above three points are the aspects that cameras focus more on, which are different from cameras.

My question is: Why are the pixels of the camera so low? Will it affect the effect?

Of course, the higher the better, the camera is static and requires higher pixels to achieve clear results. The camera is dynamic, so 1 million watts is enough, and high-definition cameras require more than 5 million watts. Therefore, regardless of the size of the pixels, the camera is not as good as the camera, and the camera is not as good as the camera. Each has its own expertise. When the dynamic is frozen in static, you will find it extremely unclear.

How to explain that the pixels of high-definition cameras are very low?

Resolution and pixels are two aspects of the same thing, or two different expressions of the same thing. Pixels As the height changes, the resolution also changes. 1600*1200 pixels, which is 2 million pixels.

The key to whether a photo is clear or not is not the pixels.

The clarity of photos has nothing to do with pixels, but has a lot to do with the size of the CCD. Cameras mainly rely on pixels, so a large CCD size is good! But photos with a large CCD without high pixels will definitely not be clear. The size of the CCD is a matter of increasing the photosensitive area, while the pixels determine the clarity of the photo!

The imaging effect of a photo depends on three aspects: first, the optical performance of the lens; second, the area size and color depth of the photosensitive device; third, the technical level of the image processor. It can be seen that the key is not the size of the pixels on the photoreceptor, but the area size and color depth of the photoreceptor.

The main function of pixels is to determine how large a clear photo can be printed. The larger the pixels, the larger the photo can be printed. If you just view it on a computer or print small-size photos, there is basically no difference between 10 million pixels and 1 million pixels.
