Information processing apparatus and information processing method

An information processing apparatus, comprising:

• a depth-information detecting section detecting, based on a depth information representing a position of an object in stereoscopic video data in a depth direction, a peak position of said object in said depth direction as a peak value, at which said object is displayed at a front in an additional information display area where additional information data is superimposed and displayed with said stereoscopic video data;
• a comparison/detection section making a comparison between depth information of said additional information and said peak value of said stereoscopic video data to detect a positional relationship between said stereoscopic data and said display position of said additional information in said depth direction in said additional information display area;
• and
• a control unit controlling said stereoscopic video data and said display position of said additional information,
• in which said peak value represents a maximum video depth value in a basic unit of said stereoscopic video data,
• in which said depth-information detecting section detects an average value which is an average of positions in said depth direction at which said object is displayed in said additional information display area for said basic unit of said stereoscopic video data, such that said depth-information detecting section detects both a respective average value and a respective peak value for a respective basic unit of said stereoscopic video data,
• in which said basic unit represents a group of pictures (GOP),
• in which the respective average value and the respective peak value are obtained for each GOP according to auto focus (AF) control information of a camera unit and are both recorded in a MDP (modified DV or digital video pack) portion for the respective GOP unit of said stereoscopic video data, such that a GOP peak value and a GOP average value are recorded in the MDP portion for the respective GOP unit, in which said comparison/detection section makes a comparison between said position of said additional information data in said depth direction and said average value to detect a positional relationship between said object of said stereoscopic video data and said additional information in said additional information display area;
• and
• in which the control unit controls said stereoscopic video data and said display position of said additional information in response to the positional relationships between said stereoscopic video data and said display position of said additional information obtained by use of the average value and the peak value for said GOP unit of said stereoscopic video data.
