Abstract
A method and an apparatus for protecting a device under powerful light are disclosed. It is determined whether there is a powerful light source in an image captured by a camera device based on the number of target pixels (pixels whose gray values are larger than the first preset threshold) in the image. If so, it is indicated that the photosensitive element in the camera device is aligned with the powerful light source. In this case, the light avoidance instruction is sent, so as to cause a photosensitive element of the camera device to avoid the light source, thereby reducing the damage caused by the powerful light to the photosensitive element in the camera device.
