Summary

Flicker is when a camera image flashes or a black line appears periodically in the image. This phenomenon occurs when a high-speed electronic shutter of a camera's image sensor is used under low-frequency lighting.

- Flicker is caused by the characteristics of alternating current.

- This phenomenon can occur when a camera is used in an environment with low-frequency fluorescent lighting or low-quality LED lighting, and is particularly noticeable when high-speed electronic shutters are used.

Step-by-step guide:

- How to eliminate this phenomenon

1. Environmentally, one way is to change the lighting. Low-frequency fluorescent lamps are replaced with high-frequency fluorescent lamps, and low-quality LED lamps are replaced with high-quality flicker-free LED lamps.

2. The next best option is to change the settings on the camera.
Activate the anti-flicker function on the camera depending on the power frequency. Alternatively, set the electronic shutter speed to a fixed value according to the power frequency. (NTSC region: 1/60s or 1/120s, PAL region: 1/50s or 1/00s)
