Abstract: In a case where generating a training image of an object to be used to generate a dictionary to be referred to in image recognition processing of detecting the object from an input image, model information of an object to be detected is set, and a luminance image of the object and a range image are input. The luminance distribution of the surface of the object is estimated based on the luminance image and the range image, and the training image of the object is generated based on the model information and the luminance distribution.

Abstract: According to an aspect of the invention, a portable terminal includes: a first audio input-output unit and a second audio input-output unit configured to receive audio when a mode is set as an input mode and output audio when the mode is set as an output mode; and a setting unit configured to set the respective modes of the first audio input-output unit and the second audio input-output unit.

Abstract: A method of storing 3D image data in a recording medium includes: loading, in a predetermined file type field, image type information indicating either one of a single stereoscopic image or a compound image including a monoscopic image and a stereoscopic image; loading, in a predetermined image configuration information container field, scene descriptor information indicating temporal and spatial relations between a plurality of media objects included in the three-dimensional image, object configuration information indicating attributes of each media object of said plurality of media objects and a configuration relation between encoded streams of the plurality of media objects, configuration information of the encoded streams; loading in an image data container field media data of an image to be stored; and loading, in a meta container field, metadata including information for playing the 3D image data.
