FIG. 5E is an exemplary drawing for explaining a method for an electronic device (101) according to an embodiment of the present document to display an object (400) based on the user's eyes being included within the first field of view range (420) when the user's head moves in a vertical direction.The field of view range (e.g., the first field of view range (420)) according to one embodiment of the present document is a spatial concept, and the user's eyes may be included in the first field of view range not only when the user's eyes move in a direction horizontal to the ground, but also when the user's eyes move in a direction vertical to the ground. As illustrated in FIG. 5E, the electronic device (101) according to one embodiment of the present document may determine whether the user's eyes are included in the first field of view range (420) when the user's eyes move in a direction vertical to the ground. If the electronic device (101) according to one embodiment of the present document determines that the user's eyes are included in the first field of view range (420), the electronic device (101) according to one embodiment of the present document may display the object (400) in three dimensions in a fixed manner based on a designated position.

[0061] According to an embodiment of the present document, the electronic device (101) may, in operation 330, display an object (400) displayed as a three-dimensional object by rotating it in a designated direction through a light field display based on the position of the user's eye within a second field of view range (430) set for the field of view of at least one camera. The second field of view range (430) according to an embodiment of the present document may be a field of view range included within the field of view of at least one camera. The second field of view range (430) according to an embodiment of the present document may be, for example, a range including a remaining area excluding the first field of view range (420) among the field of view (e.g., 120 degrees) of at least one camera (e.g., the camera module (180) of FIG. 1). In other words, the second field of view range (430) according to an embodiment of the present document may include an area that is further away from the center of at least one camera than the first field of view range (420). FIGS. 5C and 5D are exemplary drawings for explaining a method in which an electronic device (101) according to an embodiment of the present document displays an object (400) when the user's eyes are within a second field of view range (430). The electronic device (101) according to an embodiment of the present document may, based on the user's eyes being positioned within the second field of view range (430), rotate the object (400), which was being displayed in a fixed manner at a specified position on the light field display, by a specified angle (e.g., 90 degrees) and a specified direction (e.g., counterclockwise) and display it. Accordingly, based on the movement of the user's eyes (e.g., head) gazing at the object (400), most of the side of the object (400) may be shown to the user, as illustrated in FIGS. 5C and 5D. FIG. 5F is an exemplary drawing illustrating a method in which an electronic device (101) according to one embodiment of the present document displays an object based on the user's eye being included in a second field of view range (430) as the user's head moves in a vertical direction.According to one embodiment of the present document, the second field of view range (420) may also include the user's eyes in the first field of view range not only when the user's eyes move in a direction horizontal to the ground, but also when the user's eyes move in a direction vertical to the ground, as a spatial concept. As illustrated in FIG. 5F, the electronic device (101) according to one embodiment of the present document may determine whether the user's eyes are included in the second field of view range (430) when the user's eyes move in a direction vertical to the ground. As a result of the determination, when the electronic device (101) according to one embodiment of the present document identifies that the user's eyes are included in the second field of view range (430), as illustrated in FIG. 5F, the electronic device (101) may display the object (400) in three dimensions while rotating the object (400) at a specified angle (e.g., 90 degrees) and in a specified direction (e.g., counterclockwise).

[0062] An electronic device (101) according to an embodiment of the present document may, in operation 340, display an object (400) as a two-dimensional image based on the position of the user's eyes at a location (440) outside the first field of view range (420) and the second field of view range (430) set for the field of view of at least one camera. The electronic device (101) according to an embodiment of the present document may identify that the user's eyes are outside the field of view of at least one camera based on the user's movement. In this case, the electronic device (101) according to an embodiment of the present document may control the light field display so that the object (400) being displayed in three dimensions is displayed as a two-dimensional object (400). Alternatively, the electronic device (101) according to an embodiment of the present document may display a pre-specified image on the light field display instead of the image of the two-dimensional object (400). An electronic device (101) according to one embodiment of the present document can display an object (400) in two dimensions or display a specified image as a two-dimensional image by, for example, controlling projector modules, controlling a lens array, or controlling pixels included in a light field display. Accordingly, most of the front surface of the object (400) can be shown to the user.

[0063] Various embodiments of the present document are described based on the "field of view" of at least one camera (e.g., the camera module (180) of FIG. 1) for convenience of explanation, but are not limited thereto. For example, the "field of view" according to one embodiment of the present document may be used interchangeably / substituted with the "3D viewable range (e.g., the range in which the electronic device (101) can provide a 3D image)" set for the light field display. The "3D viewable range" according to one embodiment of the present document may be set based on the distance between the light field display and the user (e.g., a straight-line distance) and / or the angle between the direction of the user's eyes and the electronic device (101) (e.g., whether the user is looking at the electronic device (101) from the front or the side). For example, the electronic device (101) according to one embodiment of the present document may identify, using at least one sensor, that the user's position has moved to the right with respect to the current user's position (e.g., identify that the X-coordinate and Y-coordinate of the user's current position have changed). In this case, the electronic device (101) according to one embodiment of the present document can identify that the user has entered the second 3D viewable range from the first 3D viewable range based on the increase in the straight-line distance between the electronic device (101) (e.g., the center position of the light field display) and the user. Based on such functions or operations, the electronic device (101) according to one embodiment of the present document can be set to perform various embodiments of the present document. The electronic device (101) according to one embodiment of the present document can perform various embodiments of the present document based on the "3D viewable range" when the "3D viewable range" is set to occupy an area narrower than the "angle of view" of at least one camera.Conversely, an electronic device (101) according to one embodiment of the present document may perform various embodiments of the present document based on the “angle of view” of at least one camera, if the “3D viewable range” is set to occupy an area wider than the “angle of view” of at least one camera.
