AI Technical Summary

Problems solved by technology

However, in the process of realizing the above-mentioned flashlight flashing, the following problems exist in the prior art: the flashlight is a high-current device, if only a small amount of flashlight is required, the flashlight still performs a fixed amount of flashlight, and cannot flash according to the actual situation The amount of adjustment, which will waste the power of the shooting equipment

[0009] When the flash is used as a lighting device, the power consumption of the smart phone is also very large, which affects the battery life of the smart phone

In the existing technology, most of the flashlights of smartphones can only emit a single white light, which has high limitations, and the brightness cannot be adjusted. The flashlight is basically in the brightest state, and the light is dazzling, which affects the user experience.
