a display module;

an under display camera (UDC) module comprising a camera module and a sensor module and formed under the display module; and

a processor,

wherein the processor is configured to:

detect a trigger related to an operation of the UDC module,

identify an operation mode of the UDC module based on the trigger detection,

change a transmittance of a UDC area corresponding to a position of the UDC module in a display area of the display module to a first transmittance when the operation mode is a first designated operation mode and control the UDC module to configure a first path facing the sensor module,

obtain a first image based on light transferred to the sensor module through the first path after light from the display module is reflected from a first external object on the UDC area,

change the transmittance of the UDC area corresponding to the position of the UDC module in the display area of the display module to a second transmittance different from the first transmittance when the operation mode is a second designated operation mode and control the UDC module to configure a second path facing the camera module, and

obtain a second image based on light reflected from a second external object outside of the electronic device and transferred to the camera module through the second path.
