A method and apparatus for controlling an operation of a camera that allows a user to conveniently control a camera apparatus according to a gesture of a subject input through a lens of a camera, and the camera apparatus are provided. The method includes receiving an image input through a camera lens; generating an image frame; detecting a motion of a subject included in the image frame by comparing the image frame with at least one previous frame stored before the image frame is generated; determining whether the motion of the subject is a User Interface (UI) gesture; and performing, if the motion is the UI gesture, an operation corresponding to the UI gesture.
1. An electronic device, comprising:
a camera;
a memory;
a display configured to display a first image and a second image captured by the camera; and
a controller configured to:
detect, from the first image and the second image, a transition of a shape of a hand of a user between an opened hand and a closed hand, and
permanently store a third image, captured after detecting the transition of the shape of the hand of the user, in the memory.
2. The electronic device of the claim 1 , wherein the controller is further configured to detect the hand of the user from the first image and the second image.
3. The electronic device of the claim 1 , wherein the controller detects the transition of the shape of the hand of the user by comparing the first image and the second image with an image stored in the memory.
4. The electronic device of the claim 1 , wherein the controller temporarily stores the first image and the second image to be displayed.
5. A method of operating an electronic device, the method comprising:
capturing a user and displaying a first image and a second image that are captured;
detecting, from the first image and the second image, a transition of a shape of a hand of the user between an opened hand and a closed hand;
permanently storing a third image, captured after detecting the transition of the shape of the hand of the user.
6. The method of the claim 5 , further comprising:
detecting the hand of the user from the first image and the second image.
7. The method of the claim 5 , wherein detecting the transition of the shape of the hand of the user between the opened hand and the closed hand comprises:
comparing the first image and the second image with image stored in the memory.
8. The method of the claim 5 , further comprising:
temporarily storing the first image and the second image to be displayed.
