Abstract
A method and an apparatus for outputting stereoscopic images in a mobile terminal are provided. The method includes entering a play control command for a stereoscopic video, searching for an I-frame (key frame) corresponding to a changed play position; determining, after decoding the found I-frame, whether the decoded I-frame is a left frame (L-frame) or a right frame (R-frame), adjusting, when the decoded I-frame is an R-frame, L-R sequencing, and outputting a stereoscopic image based on the adjusted L-R sequence. Hence, the mobile terminal may output a stereoscopic image in a manner that the stereoscopic effect intended by the content author is fully conveyed by the mobile terminal.
Claims16
A method for outputting stereoscopic images in a mobile terminal, the method comprising:
- entering a play control command changing a play position for a stereoscopic video;
- searching for an I-frame (key frame) corresponding to the changed play position;
- determining, after decoding the searched I-frame, whether the decoded I-frame is a left frame (L-frame) or a right frame (R-frame);
- adjusting, when the decoded I-frame is an R-frame, an L-R sequence by receiving an L-frame in the L-R sequence and then combining the I-frame and the received L-frame;
- and
- outputting, based on the adjusted L-R sequence, a stereoscopic image based on the adjusted L-R sequence,
- wherein the searching for the I-frame comprises:
- determining whether a frame corresponding to the changed play position is an I-frame or a P-frame (delta frame);
- and
- finding, when the frame corresponding to the changed play position is a P-frame, an I-frame closest to the found P-frame.
A mobile terminal capable of outputting stereoscopic images, the mobile terminal comprising:
- a display for outputting stereoscopic images;
- an input for receiving a play control command for a stereoscopic video from a user;
- a controller configured to implement a video decoder for searching for an I-frame (key frame) corresponding to a changed play position and for decoding the searched I-frame;, an L-R frame determiner for determining whether the decoded I-frame is a left frame (L-frame) or a right frame (R-frame);, and an image output controller for adjusting, when the decoded I-frame is an R-frame, a L-R sequence and for controlling the display unit to output a stereoscopic image based on the adjusted L-R sequence,
- wherein the video decoder determines whether a frame corresponding to the changed play position is an I-frame or a P-frame (delta frame), and finds, when the frame corresponding to the changed play position is a P-frame, an I-frame closest to the found P-frame.
