Why is there a small blue circle when the mobile phone is backlit?

When the mobile phone takes a picture of the sun, a small blue circle will appear, which is the refraction of light, and the sunlight is refracted through the lens of the mobile phone. Halo caused by lens optical effect generally does not affect the picture effect.

The mobile phone's own photography is based on the mobile phone with photography function. Photography, as a rapidly spreading hobby, is not only a simple entertainment, but also an important way for people to stop, observe people and things around them with photography and appreciate life from a new angle.

As a communication tool carried by modern people, mobile phones have also become the most convenient shooting tool, allowing people to observe and record the dribs and drabs of life with a more peaceful, delicate and simple mind.

Extended data:

With the accelerated pace of urban life, people's material life is getting richer and richer, and their spiritual life is getting scarcer and scarcer. Spiritual civilization is an important part of building a harmonious society. Only when spiritual civilization and material civilization develop together can we build a harmonious socialist society.

As a rapidly spreading hobby, photography can help people to establish a correct aesthetic view, enrich the increasingly empty spiritual civilization, and finally achieve the goal of improving people's quality of life and building a harmonious society.
