Does the Apple video flash indicate poor light?

Apple 13 records video with flashing lights: lights or screen lights, lights and screen light sources will be captured by the camera due to stroboscopic effect, resulting in unstable visual phenomena in the picture.

Because strongpoint exceeded the standard, strongpoint is everywhere in the lamps! However, as long as all lamps are connected with alternating current, there will be "stroboscopic". The reason of stroboscopic is that the refresh frequency of the two appliances is different. The "strobe" of lighting can be divided into visible and invisible, and the obvious stripe fluctuation visible to naked eyes or mobile phones is video strobe.

Apple 13 video body design: iPhone 13 successfully reduced bangs by moving up the receiver, which not only brought about a further increase in the screen ratio, but also represented a further upgrade of the Face ID area. On the front of iPhone 13, the Face ID area integrates components including microphone, speaker, front camera, ambient light sensor, distance sensor, infrared lens, floodlight, dot matrix projector and so on. Shrink bangs by 20%.
