control a display to display the plurality of third images during the acquiring of the fourth image from the server; and

control the display to display the fourth image after displaying the plurality of third images.

12. The electronic apparatus of claim 11 , wherein the at least one instruction, when executed, causes the at least one processor to estimate a time required for the server to acquire the fourth image to adjust a number of third images to be acquired or a display time of the plurality of third images.

13. A method of controlling an electronic apparatus, comprising:

identifying a feature of at least one object included in a first image;

identifying a feature of at least one object included in a second image, the second image being acquired by applying the first image to a first neural network;

determining an image processing method based on the identification;
