A method for controlling a movable image acquisition component of a terminal, the method comprising: when the terminal receives an activating instruction for the movable image acquisition component, obtaining acquired data acquired by a proximity sensor, P-sensor, the movable image acquisition component being capable of moving in and out of the terminal under driving of a driving component of the terminal; determining whether there is an obstacle in a preset range of the terminal based on the acquired data, wherein the preset range of the terminal is a distance range of the obstacle relative to the terminal, and the obstacle is an object that stops the movable image acquisition component from moving out or damage the movable image acquisition component; and when there is the obstacle in the preset range of the terminal, forbidding the activating instruction to be executed, and keeping the movable image acquisition component at a first position in the terminal, wherein the first position is an original position of the movable image acquisition component within the terminal, characterized in that the movable image acquisition component is turnable, the terminal comprises at least two P-sensors of which orientations of sensing surfaces are different, and the method further comprises: when an image acquisition surface of the movable image acquisition component faces a first surface, activating the P-sensor corresponding to the first surface; and when it is detected that the image acquisition surface of the movable image acquisition component turns from the first surface to a second surface, activating the P-sensor corresponding to the second surface while turning off the P-sensor corresponding to the first surface to keep the sensing surface of the P-sensor, from which the data are acquired, and the image acquisition surface of the movable image acquisition component face the same surface. when the terminal receives an activating instruction for the movable image acquisition component, obtaining acquired data acquired by a proximity sensor, P-sensor, the movable image acquisition component being capable of moving in and out of the terminal under driving of a driving component of the terminal; determining whether there is an obstacle in a preset range of the terminal based on the acquired data, wherein the preset range of the terminal is a distance range of the obstacle relative to the terminal, and the obstacle is an object that stops the movable image acquisition component from moving out or damage the movable image acquisition component; and when there is the obstacle in the preset range of the terminal, forbidding the activating instruction to be executed, and keeping the movable image acquisition component at a first position in the terminal, wherein the first position is an original position of the movable image acquisition component within the terminal, characterized in that the movable image acquisition component is turnable, the terminal comprises at least two P-sensors of which orientations of sensing surfaces are different, and the method further comprises: when an image acquisition surface of the movable image acquisition component faces a first surface, activating the P-sensor corresponding to the first surface; and when it is detected that the image acquisition surface of the movable image acquisition component turns from the first surface to a second surface, activating the P-sensor corresponding to the second surface while turning off the P-sensor corresponding to the first surface to keep the sensing surface of the P-sensor, from which the data are acquired, and the image acquisition surface of the movable image acquisition component face the same surface. when an image acquisition surface of the movable image acquisition component faces a first surface, activating the P-sensor corresponding to the first surface; and when it is detected that the image acquisition surface of the movable image acquisition component turns from the first surface to a second surface, activating the P-sensor corresponding to the second surface while turning off the P-sensor corresponding to the first surface to keep the sensing surface of the P-sensor, from which the data are acquired, and the image acquisition surface of the movable image acquisition component face the same surface.
