Electronic device and method for improving quality of image by using multiple cameras

An electronic device comprising:

• a first camera module;
• a second camera module;
• a processor;
• and
• memory storing instructions that, when executed by the processor, cause the electronic device to:
• perform video shooting by using the first camera module,
• receive a request to capture a picture image while the video shooting is performed by the first camera module,
• determine whether a current configuration value of the second camera module needs to be changed, wherein the current configuration value of the second camera module comprises at least one of an exposure value (EV) or a shooting frame number,
• based on determining that the current configuration value of the second camera module needs to be changed, change the current configuration value of the second camera module,
• based on the request to capture the picture image, acquire at least one image frame by using the second camera module of which the current configuration value is changed, and
• generate an image corresponding to the request to capture the picture image, based on an image frame acquired by using the first camera module and the at least one image frame acquired by using the second camera module while the video shooting is performed.
