What are the advantages of the dual camera behind the mobile phone?

The dual camera of a mobile phone consists of a main camera and an auxiliary camera. But the biggest use of this collocation is not to improve the clarity of photos, but to make the photos taken by mobile phones have the effect of professional SLR lenses.

There are two common dual cameras on the market now, one is color camera+auxiliary camera; The other is color camera+black and white camera. So what are their advantages?

Color camera+auxiliary camera: Generally, the pixels of the auxiliary camera will be lower, but it will not directly affect the image quality. The improvement of image quality and definition is not great, but focusing first will blur the background, increase the interest of taking pictures and easily shoot large films.

Color camera+black and white camera: color camera is responsible for collecting picture color, and black and white lens is responsible for supplementing luminosity and details. So the details of the photo will be clearer when taking pictures.

The focal lengths of the two lenses are different, one is wide angle and the other is zoom. Wide-angle shooting can be carried out, and the scene can be clearly enlarged when shooting the distant view.

Use independent modules with independent sensors. This design will not affect the shooting in low light environment, and the picture quality is still very good.

After taking pictures, it presents a 3D naked-eye effect. LG, HTC and Sharp are all pioneers of naked-eye 3D, so the photos taken will be more realistic and stereoscopic.
