Information processing apparatus, information processing method, and computer-readable recording medium

A playback method comprising:

• decoding video data compressed and encoded, by using a first decoder, thereby generating a first image frame;
• issuing an execution command for switching non-execution of three-dimensional image generation to execution of the three-dimensional image generation;
• instructing a second decoder to decode the video data, starting with a picture from which is generated an image frame independent of any other image frame of the video data, when the execution command is issued;
• decoding the video data by using the second decoder, thereby generating a second image frame corresponding to the first image frame;
• inferring, by using a depth map generating module, depth values for pixels contained in the second image frame, thereby generating a depth map;
• and
• generating left-eye image data and right-eye image data based on the depth map and the first image frame, by using a three-dimensional image generating module.

A computer-readable, non-transitory storage medium having stored thereon a computer program which is executable by a computer, the computer program controlling the computer to execute functions of:

• causing a first decoder to decode a video data, thereby generating a first image frame;
• issuing an execution command for switching non-execution of three-dimensional image generation to execution of the three-dimensional image generation;
• instructing a second decoder to decode the video data, starting with a picture from which is generated an image frame independent of any other image frame of the video data, when the execution command is issued;
• causing the second decoder to decode the video data, thereby generating a second image frame corresponding to the first image frame;
• causing a depth map generating module to infer depth values for pixels contained in the second image frame, thereby generating a depth map;
• and
• causing a three-dimensional image generating module to generate left-eye image data and right-eye image data based on the depth map and the first image frame.
