A display apparatus comprising: a storage configured to store a Virtual Reality, VR, image; a user interface; a display; and a processor configured to: convert the VR image into a spherical VR image, obtain a planar VR image corresponding to an area of the spherical VR image according to a projection method, control the display to display the planar VR image, in response to a first user input, through the user interface, to select a first object from an editing tool for performing a first editing operation on the planar VR image being received, overlay the first object provided by the editing tool to be placed entirely within the planar VR image and control the display to display the first object overlaid on the planar VR image, obtain a second object by inversely performing the projection method to project the first object as the second object in a spherical coordinate system, receive a second user input, through the user interface, to perform a second editing operation on the first object, in response to receiving the second user input, apply the second editing operation to the second object in the spherical coordinate system, change the first object by applying the projection method to the changed second object, control the display to display the changed first object (330, 430, 510) overlaid on the planar VR image. a storage configured to store a Virtual Reality, VR, image; a user interface; a display; and a processor configured to: convert the VR image into a spherical VR image, obtain a planar VR image corresponding to an area of the spherical VR image according to a projection method, control the display to display the planar VR image, in response to a first user input, through the user interface, to select a first object from an editing tool for performing a first editing operation on the planar VR image being received, overlay the first object provided by the editing tool to be placed entirely within the planar VR image and control the display to display the first object overlaid on the planar VR image, obtain a second object by inversely performing the projection method to project the first object as the second object in a spherical coordinate system, receive a second user input, through the user interface, to perform a second editing operation on the first object, in response to receiving the second user input, apply the second editing operation to the second object in the spherical coordinate system, change the first object by applying the projection method to the changed second object, control the display to display the changed first object (330, 430, 510) overlaid on the planar VR image. convert the VR image into a spherical VR image, obtain a planar VR image corresponding to an area of the spherical VR image according to a projection method, control the display to display the planar VR image, in response to a first user input, through the user interface, to select a first object from an editing tool for performing a first editing operation on the planar VR image being received, overlay the first object provided by the editing tool to be placed entirely within the planar VR image and control the display to display the first object overlaid on the planar VR image, obtain a second object by inversely performing the projection method to project the first object as the second object in a spherical coordinate system, receive a second user input, through the user interface, to perform a second editing operation on the first object, in response to receiving the second user input, apply the second editing operation to the second object in the spherical coordinate system, change the first object by applying the projection method to the changed second object, control the display to display the changed first object (330, 430, 510) overlaid on the planar VR image.
