  10. The electronic device (100) of claim 9, wherein, by executing the instructions, the at least one processor (2010) is further configured to: output a first notification based on a position of the target object in a second preview image based on the first viewing angle; output a second notification based on the target object not being included in the second preview image; and alternatively locking and unlocking the target object based on an event of selecting the second preview image, wherein the first notification is changed according to a movement of the first viewing angle.
  11. The electronic device (100) of claim 9, wherein, by executing the instructions, the at least one processor (2010) is further configured to: recognize the target object based on at least one of a direction corresponding to the hand gesture and a touch by the hand gesture.
  12. The electronic device (100) of claim 9, wherein, by executing the instructions, the at least one processor (2010) is further configured to: obtain a zoom-in request for a portion of the target object in based on the portion corresponding to an interaction with a user; storing a result of analyzing an intention of the user based on the predetermined viewing angle, corresponding to the photographing screen, and wherein the target object is locked after photographing the target object.
  13. The electronic device (100) of claim 9, wherein, by executing the instructions, the at least one processor (2010) is further configured to: process a stepwise recognition setting for the target object based on an interaction with a user; and process collective release of the stepwise recognition setting for the target object based on a second interaction with the user.
  14. The electronic device (100) of claim 9, wherein, by executing the instructions, the at least one processor (2010) is further configured to: set a plurality of objects among the at least one object included in the first preview image as the target object based on the hand gesture; identify an object of interest in the first preview image; output the object of interest that is identified; and recognize the object of interest as the target object based on the hand gesture.
