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.

A method for outputting stereoscopic images in a mobile terminal, the method comprising:
- 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.
A method for determining whether a frame is a left frame (L-frame) or a right frame (R-frame) in a stereoscopic video including multiple frames, the method comprising:
- extracting frame information from a selected frame of the stereoscopic video;
- determining, when the extracted frame information is a frame number in the frame sequence, whether the frame number is odd or even;
- and
- determining that the selected frame is an L-frame when the frame number is odd, and determining that the selected frame is an R-frame when the frame number is even.
A mobile terminal capable of outputting stereoscopic images, the mobile terminal comprising:
- a display unit for outputting stereoscopic images;
- an input unit for receiving a play control command for a stereoscopic video from a user;
- a video decoder for searching for an I-frame (key frame) corresponding to a changed play position and for decoding the found 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, L-R sequencing and for controlling the display unit to output a stereoscopic image based on the adjusted L-R sequence.
