其中,本申请实施例中,上述视频功能可包括以下任意一种:视频聊天功能(如微信视频、QQ视频等)、视频拍摄功能等等,在此不作限定。由于电子设备的天线与摄像头距离较近,在摄像头被开启视频功能后,天线与摄像头同时工作时的工作频率会互相干扰,因此,获取摄像头的第一工作频率,并获取天线的第二工作频率。具体实现中,电子设备可依据预设的时间周期获取摄像头的第一工作频率和天线的第二工作频率,预设的时间周期可以由用户自行设置或者系统默认。
102、根据所述第一工作频率确定所述第二工作频率是否受到干扰。

105、从所述工作频率列表中确定出对所述第二工作频率产生的干扰小于所述第一工作频率的至少一个第三工作频率。
其中,电子设备中可以从工作频率列表中确定出对第二工作频率产生的干扰小于第一工作频率的至少一个第三工作频率,具体地,第三工作频率不与第二工作频率相同或者呈现倍频关系。

B3、若否,执行所述以所述目标第三工作频率控制摄像头进行工作,以及依据所述目标帧率实现所述视频功能的步骤。
具体实现中,电子设备可以在第二工作频率变化时,检测该第一目标工作 频率是否干扰了变化后的第二工作频率,具体地,检测第一目标工作频率是否与第二工作频率相同或者呈现倍频关系,在第一目标工作频率干扰了变化后的第二工作频率,则从至少一个第三工作频率中选取一个对变化后的第二工作频率小于第一目标工作频率的第三工作频率作为第二目标工作频率,并按照预设的摄像头的工作频率与摄像头的帧率之间的映射关系,确定第二目标工作频率确定对应的摄像头的第二目标帧率,并以第二目标工作频率控制摄像头进行工作,以及依据第二目标帧率实现视频功能,反之,则继续执行步骤106。
