Apparatus and method for providing fingerprint recognition and photographing based on under display camera in electronic device

An electronic device comprising:

• 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.
