Optionally, the user's eyes are detected and located. There may be multiple users. Therefore, the user's eyes in the scene may be multiple eyes. If the user's eyes are blocked, an odd number of eyes may appear. In some specific scenarios, if the user is far away from the camera lens, in this case, the mobile terminal will recognize the eyes of the nearby users, and the camera will be controlled by the blinking action of the nearest user; when the human eyes are detected by other transparent objects Or if the reflective object is blocked, the mobile terminal can perform highlight denoising processing on the situation such as mirror reflection, so that the mobile terminal can more conveniently identify human eyes.
