Abstract: An image display apparatus configured to zoom display an image to be displayed on a display area has a position specifying unit that specifies a position of an object contained in a displayed image, a position deciding unit that decides a positional relationship between an outer frame of the display area and the position of the object, and a zoom speed changing unit that changes a zoom speed in the zoom display depending on the decided positional relationship.

Abstract: A gesture recognition device that recognizes a gesture of a person from an image captured by a camera, and outputs information to an electronic apparatus in order to control the electronic apparatus based on the recognized gesture, has a person determination section that determines whether the person is included in the image, and an output section that outputs person out-of-view angle notification instruction information issuing an instruction to make a notification that the image of the person is not captured, when the person determination section determines that the person is not included in the image.

Abstract: An attribute of image data can accurately be discriminated. An image attribute discrimination apparatus includes a heterogeneous region extracting unit that specifies a heterogeneous region from image data. The heterogeneous region includes a heterogeneous matter whose attribute is different from that of a content originally produced by the image data. An image attribute discrimination apparatus further includes a scene discrimination unit that discriminates the attribute of the image data based on a feature quantity extracted from a pixel group except each pixel in the heterogeneous region in each pixel of the image data.

Abstract: Included are a reference image retrieving section (23) which retrieves a reference image with use of an entered keyword, a related image retrieving section (25) which retrieves a related image which (i) is included in a related range correlated with the keyword and (ii) relates to the reference image, and an image outputting section (27) which outputs the reference image and the related image as a retrieval result.

Abstract: An image processing device selects an image in which sharpness of a photographic subject is relatively high compared with sharpness of a background. The image processing device includes a photographic subject detection unit that identifies a photographic subject region on an image, which includes a predetermined photographic subject, by detecting the predetermined photographic subject from the image, a background region identifying unit that identifies a background region on the image, which is other than the photographic subject region, a sharpness identifying unit that identifies sharpness of the photographic subject region and sharpness of the background region, a score calculation unit that calculates a score based on a difference in the sharpness between the photographic subject region and the background region, and a determination unit which determines the image as an optimum image when the score indicates that photographic subject region is clearer than the background region.

Abstract: An authentication apparatus comprises an extraction part configured to extract a feature of a face from a face image of a user; a plurality of classifiers configured to identify the user by determining whether or not the feature extracted by the extraction part matches a feature of a face stored in a storage apparatus; a deriving part configured to derive a specific condition based on at least one of the feature extracted by the extraction part and information for authenticating the user; a selecting part configured to select at least one of the classifiers based on the specific condition; and an authentication part configured to authenticate the user when the selected classifier determines that the feature extracted by the extraction part matches the feature of the face stored in the storage.

Abstract: To prevent actions other than gestures from being falsely recognized as gestures by a gesture recognition device that recognizes gestures performed by a user. A gesture recognition device that acquires a gesture performed by a user and generates a command corresponding to said gesture, includes: a gesture acquisition unit for acquiring a gesture performed by a user; a gaze tracking unit for acquiring the user's movement of gaze; a gaze pattern determination unit for determining whether the movement of gaze satisfies a prescribed pattern; a gesture selection unit selecting a valid gesture acceptable as input when the movement of gaze satisfies a prescribed pattern; and a command generating unit for generating a command corresponding to the acquired gesture only if said acquired gesture is a valid gesture. Thus, the gesture recognition device that recognizes gestures performed by a user can prevent actions other than gestures from being falsely recognized as gestures.

Abstract: A gesture recognition device that recognizes a gesture, which is of a motion or a shape of a gesture recognition target region of a person, from an image captured by a camera and outputs information to an electronic apparatus in order to control the electronic apparatus based on the recognized gesture, has a recognition target region determination section that determines whether the gesture recognition target region is included in the image, and an output section that outputs target region out-of-view angle notification instruction information issuing an instruction to make a notification that an image of the gesture recognition target region is not captured when the recognition target region determination section determines that the gesture recognition target region is not included in the image.
