In the embodiment of the present invention, judging whether the rotatable camera of the mobile terminal satisfies the first rotation condition is because the video call needs to turn on the camera to collect image information, so before answering the video call, it is necessary to judge the rotatable camera of the mobile terminal It is determined whether the rotatable camera of the mobile terminal satisfies the first rotation condition whether it needs to be rotated to a position aimed at the user. Judging whether the rotatable camera of the mobile terminal satisfies the first rotation condition can be realized by the following methods: starting the rotatable camera; controlling the rotatable camera to take pictures to obtain image information W; combining the image information W with Match the image information of the user stored in advance; if the image information W is inconsistent with the image information of the user stored in advance, it means that the current position of the rotatable camera cannot collect the image information of the user, then it is judged that The rotatable camera of the mobile terminal satisfies the first rotation condition; if the image information W is matched with the pre-stored user image information, it means that the current position of the rotatable camera can collect the user's image information , judging that the rotatable camera of the mobile terminal does not meet the first rotation condition.
