Why can't a high-pixel mobile phone take pictures compared with a low-pixel SLR camera?

Although the pixels of a SLR camera are very low, the optical zoom of its lens is perfect, which is naturally much clearer than a high-pixel mobile phone. Consumers who use high-pixel mobile phones and SLR cameras will find that many high-pixel mobile phones on the market are not as good as low-pixel SLR cameras; Is it high pixels or high? Why is the difference so big? You can't even shoot dynamic characters clearly? This needs to talk about optical zoom and digital zoom. Most mobile phones are mainly digital zoom.

First, the reason why SLR cameras shoot high definition is because they use real physical shooting effects and perfect lens framing.

As the favorite high-end electronic equipment for photographers, SLR camera is a device that really uses physical shooting, and preserves the real scenery in photos through optical zoom and other technologies. The same digital camera, the perfection of SLR camera is irreplaceable by micro-single camera and ordinary digital camera; Relying on perfect optical zoom technology and full professional cameras, we truly recorded what we saw. The problem of pixels has little to do with it, and low pixels are also equipped with perfect shooting results.

Second, high-pixel mobile phones mainly focus on digital zoom, and photos are calculated by numbers instead of direct physical framing.

Our high-pixel mobile phone is different. Not professional shooting equipment, even high-end camera phones can't compare with SLR. Most high-pixel mobile phones in the market are mainly based on hybrid zoom, supplemented by digital zoom and optical zoom. Digital zoom is not a real physical imaging, but a photo obtained by calculation. The cost is really low, but the effect is really disappointing. Even if the pixels are large, the magnification effect is not as good as that of low-pixel SLR camera photos.

SLR camera is a professional physical imaging shooting equipment, which will be used naturally. Computational imaging? High-pixel phones are more valuable.
