An electronic device is disclosed. The electronic device can: select an object from among one or more objects included in an input image; identify indication information about a state change of the selected object; and obtain, on the basis of the indication information, a prompt related to the input image. The prompt can include one or more words for changing the state of the selected object included in the input image. The state can be included in different states of the selected object. The electronic device inputs the input image and the prompt into a generative artificial intelligence model, and thus can generate one or more result images in which the state of the selected object has been changed.
