The method according to claim 1 , wherein, in response to the first input, displaying a target control on the first shooting preview interface after the zoom factor is enlarged, and outputting prompt information, further comprising: 2 . : receiving a second input from the user on the target shooting subject on the second shooting preview interface, wherein the second shooting preview interface is the shooting preview interface before the zoom factor is enlarged; In response to the first input, the target control is displayed on the first shooting preview interface after the zoom factor is enlarged, and prompt information is output, including: In response to the first input and the second input, a target control is displayed on the first shooting preview interface, and the prompt information is output. 3. The method of claim 1, further comprising: In the case that the first control and the second control are coincident, the target control is displayed according to the target color. 4. The method according to claim 1, characterized in that, after the target control is displayed on the shooting preview interface in response to the first input, and prompt information is output, the method further comprises: receiving a third input from the user for canceling zooming in on the zoom factor of the camera; In response to the third input, the display of the target control on the first shooting preview interface is canceled. 5. A device for photographing prompts, wherein the device comprises: a first receiving module, configured to receive a first input from a user to enlarge the zoom factor of the camera; An output module, configured to display a target control on the first shooting preview interface after zooming in in response to the first input, and output prompt information, wherein the target control includes a first control and a second control, and the The prompt information is used to prompt the user to adjust the shooting angle of the camera, so that the second control and the first control are coincident, and the first control is used to represent the difference between the target shooting subject and the center point of the interface before zooming in. The first relative state information, the second control is used to represent the second relative state information of the target shooting subject and the center point of the interface after the zoom factor is enlarged, and the center point of the interface is the shooting preview interface obtained by the camera the center point; Wherein, the target control further includes a three-dimensional coordinate system established with the center point of the interface as the coordinate origin, and the three-dimensional coordinate system is based on the position of the center point of the interface, the acquired acceleration sensor data and gravity sensor data of the electronic device built; Before the first control is enlarged by the zoom factor, the first connecting line between the target shooting subject and the center point of the interface indicates that after the second control is enlarged by the zoom factor, the target shooting subject and the The second connecting line representation of the center point of the interface. 6. The apparatus of claim 5, further comprising: The second receiving module is configured to receive the second input from the user to the target shooting subject on the second shooting preview interface, wherein the second shooting preview interface is the shooting preview interface before the zoom factor is enlarged; The output module is specifically configured to display a target control on the first shooting preview interface in response to the first input and the second input, and output the prompt information. 7. The apparatus of claim 5, further comprising: The display module is configured to display the target control according to the target color when the first control and the second control overlap. 8. The apparatus of claim 5, further comprising: a third receiving module, configured to receive a third input that the user cancels the zooming in of the camera; A canceling module, configured to cancel the display of the target control on the first shooting preview interface in response to the third input.
