Stereoscopic image encode device and method, and stereoscopic image decode device and method

A stereoscopic image decode device that decodes encoded data of a stereoscopic image displayed on a display device which includes a light control unit capable of controlling directions of light beams in specific cycles and includes a display for emitting light beams from a plurality of sub-pixels through the light control unit, the stereoscopic image decode device comprising:

• a decoding unit configured to decode the encoded data to obtain a plurality of divided image;
• a determining unit configured to, based on mapping information in which the direction of emission of a light beam from each sub-pixel of the display device is set, determine a dividing method to divide the stereoscopic image for each color component;
• and
• a generating unit configured to, based on the dividing method, generate the stereoscopic image from the plurality of divided image.

A stereoscopic image encode method for encoding a stereoscopic image displayed on a display device which includes a light control unit capable of controlling directions of light beams in specific cycles and includes a display for emitting light beams from a plurality of sub-pixels through the light control unit, the stereoscopic image encode method comprising:

• determining, when the number of sub-pixels corresponding to a single cycle of the light control unit is not an integral multiple of the number of parallaxes set with respect to the stereoscopic image, a dividing method to divide the stereoscopic image for each color component based on mapping information in which the direction of emission of a light beam from each sub-pixel is set;
• generating, a plurality of divided image from the stereoscopic image based on the dividing method;
• and
• encoding the plurality of divided image.
