Photographing method and apparatus

An electronic device comprising:

• a communication interface;
• a camera;
• a display;
• a memory;
• and
• a processor configured to:
• establish a communication connection with an external device associated with a photographing target;
• identifying a photographing distance and a photographing angle with respect to the external device based on timings of UWB ranging signals transmitted and received through the communication interface;
• acquire a scene image based on an output of the camera;
• identify a current composition model based on the photographing distance, the photographing angle and the scene image;
• acquire a set of photographing parameters that are associated with the current composition model;
• identify a photographing parameter based on the set of photographing parameters and the photographing distance, wherein the photographing parameter comprises a focal length;
• control the display to display a preview image based on the output of the camera, the photographing parameter and the current composition model;
• output the preview image as a photographing result based on a photographing instruction;
• and
• update the set of photographing parameters based on the photographing parameter.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to control an electronic device to perform a photographing method comprising:

• establishing a communication connection with an external device associated with a photographing target;
• identifying a photographing distance and a photographing angle with respect to the external device based on timings of UWB ranging signals transmitted and received through the communication connection;
• acquiring a scene image based on an output of a camera of the electronic device;
• identifying a current composition model based on the photographing distance, the photographing angle and the scene image;
• acquiring a set of photographing parameters that are associated with the current composition model;
• identifying a photographing parameter based on the set of photographing parameters and the photographing distance, wherein the photographing parameter comprises a focal length;
• generating and displaying a preview image based on the output of the camera, the photographing parameter and the current composition model;
• outputting the preview image as a photographing result based on a photographing instruction;
• and
• updating the set of photographing parameters based on the photographing parameter.
