A terminal, comprising a screen, a camera and a processor, wherein the screen comprises a movable first sub-screen, wherein the camera is located below the first sub-screen; and the processor is configured to: when receiving a first instruction for enabling the camera, control the first sub-screen to move so that the camera changes from a first state to a second state; and when receiving a second instruction for disabling the camera, control the first sub-screen to move so that the camera changes from the second state to the first state, wherein when in the first state, the camera is covered by the first sub-screen, and when in the second state, the camera is exposed out of the first sub-screen; wherein the screen further comprises a fixed second sub-screen, the first sub-screen and the second sub-screen are disposed independently, and when the camera is completely covered by the first sub-screen, the first sub-screen and the second sub-screen form a complete screen; characterised in that the terminal further comprises a compressible component, and the first sub-screen is disposed on the compressible component; when controlling the first sub-screen to move so that the camera changes from the first state to the second state, the processor is specifically configured to: control the compressible component to be compressed by a preset height so that the first sub-screen descends to the position below the inner surface of the second sub-screen, and control the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the first state to the second state; when controlling the first sub-screen to move so that the camera changes from the second state to the first state, the processor is specifically configured to: control the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the second state to the first state, and after the camera changes from the second state to the first state, control the compressible component to be decompressed by the preset height so that the first sub-screen to ascend to a position aligned with the second sub-screen. the processor is configured to: when receiving a first instruction for enabling the camera, control the first sub-screen to move so that the camera changes from a first state to a second state; and when receiving a second instruction for disabling the camera, control the first sub-screen to move so that the camera changes from the second state to the first state, wherein when in the first state, the camera is covered by the first sub-screen, and when in the second state, the camera is exposed out of the first sub-screen; wherein the screen further comprises a fixed second sub-screen, the first sub-screen and the second sub-screen are disposed independently, and when the camera is completely covered by the first sub-screen, the first sub-screen and the second sub-screen form a complete screen; characterised in that the terminal further comprises a compressible component, and the first sub-screen is disposed on the compressible component; when controlling the first sub-screen to move so that the camera changes from the first state to the second state, the processor is specifically configured to: control the compressible component to be compressed by a preset height so that the first sub-screen descends to the position below the inner surface of the second sub-screen, and control the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the first state to the second state; when controlling the first sub-screen to move so that the camera changes from the second state to the first state, the processor is specifically configured to: control the first sub-screen to move below the inner surface of the second sub-screen so that the camera changes from the second state to the first state, and after the camera changes from the second state to the first state, control the compressible component to be decompressed by the preset height so that the first sub-screen to ascend to a position aligned with the second sub-screen.
