VIRTUAL REALITY IMAGE SWITCHING METHOD FOR IMPLEMENTING FRAME SYNCHRONIZATION BY CONTROLLING SWITCHING TIME POINT BETWEEN DIVIDED IMAGES EXPRESSING VIRTUAL REALITY, AND VIRTUAL REALITY IMAGE REPRODUCTION DEVICE
VIRTUAL REALITY IMAGE SWITCHING METHOD FOR IMPLEMENTING FRAME SYNCHRONIZATION BY CONTROLLING SWITCHING TIME POINT BETWEEN DIVIDED IMAGES EXPRESSING VIRTUAL REALITY, AND VIRTUAL REALITY IMAGE REPRODUCTION DEVICE
The present invention provides a virtual reality image switching method for implementing frame synchronization by controlling a switching time point between divided images expressing virtual reality, the method comprising the steps of: (a) determining a key frame distance (KFD) of a divided image expressing a part of an original image for implementing virtual reality; and (b) when a reproduced divided image is switched according to a change in the gaze of a user, allowing execution of switching of the divided image only in a key frame among frames configuring the divided image, so as to achieve frame synchronization between divided images before and after the switching.
