Abstract
In a method for adjusting a photographic lamp of an electronic device, the electronic device obtains a preview image from a camera device of the electronic device, and obtains a brightness value of an ambient environment of the electronic device. When a human face is detected in the obtained preview image, the electronic device changes a current output power value of the photographic lamp to be a first output power value, according to the obtained brightness value. When no human face is detected in the obtained preview image, the electronic device changes the current output power value to be a second output power value according to the obtained brightness value.
