An image region extraction device for extracting a target region on the basis of a designated region with high precision. An image region extraction device () extracts a target region from an image on the basis of a designated region and is provided with: a spatial change learning unit () for acquiring, for each section of the image, a pixel value changing pattern which is a characteristic of the spatial changes in a pixel value component, and a distance changing pattern which is a characteristic of the spatial changes in a distance component extending from a reference position to a photographic object; and a region dividing unit () for extracting a target region on the basis of the similarities between the pixel value changing pattern and the distance changing pattern among the designated region and each section of the image.

Disclosed is an information processing apparatus including virtual object management section () that manages virtual object management information of the information processing apparatus thereof on a virtual object disposed in an augmented real space shared by a group to which this information processing apparatus belongs. Communication section () receives virtual object management information of another information processing apparatus from this other information processing apparatus belonging to another group, the information regarding a virtual object disposed in an augmented real space shared in the other group. Reference point setting section () sets a common reference point based on the virtual object management information of the information processing apparatus and the virtual object management information of the other information processing apparatus, the common reference point being commonly used by the other group and the group to which the information processing apparatus belongs.

The picture quality of captured images can be improved with the degradation of clearness of image-captured object boundaries suppressed. An image processing apparatus () comprises: an image/distance acquiring unit () that acquires corresponding pixel pairs between left-eye and right-eye images, its depth information and its matching scores; a weight information calculating unit () that determines, for each of the pixel pairs, a weight of each of the pixels in a certain area including, as pixels of interest, the pixel pair on the basis of the depth information and the matching scores; and a pixel value superimposing unit () that applies, for each of the pixel pairs, the weight to the pixel values in the aforementioned certain area, thereby performing a smoothing process in at least one of the two images and that superimposes the two images using the values obtained by the smoothing process.

Image processing apparatus and image processing method

There is provided an image processing apparatus for performing a stable attention condition determination, regardless of the shape and surrounding environment of an object of interest and regardless that the object is unknown or known. The image processing apparatus comprises a direction detector, a displacement detector, and an attention condition determiner. The direction detector detects, from a certain image including a person image, the direction information in two body regions of a person represented by the person image. The displacement detector calculates, from the two direction information, a displacement ratio that is the ratio between the two direction displacements. The attention condition determiner determines, according to a first and a second displacement ratio, how much the person pays attention to a certain object. The first displacement ratio is calculated in the displacement detector by using first direction information detected by the direction detector from a first certain image including a first person image, and the second displacement ratio is calculated in the displacement detector by using second direction information detected by the direction detector from a second certain image including the first person image.
