摘要： A system and method displays a realistic image that allows a user to readily grasp his/her own positional relationship and also to experience a sense of presence. An outer dome screen is disposed so as to surround a user, and an immersion image such as the scenery of the surroundings of an object is displayed thereon. An inner dome screen is disposed inside the outer dome screen, and it displays a bird's-eye image of the object as perceived by the vision of the user when the object is viewed from a viewpoint of the user. In this case, the user is allowed to readily grasp his/her own positional relationship by the bird's-eye image and is allowed to experience a sense of presence by the immersion image.

摘要： An image processing apparatus displays a realistic image depending on a user's viewpoint. A sensor control unit 41 detects a user's viewpoint and a point of interest based on signals from various sensors, and outputs the detected viewpoint and point to a depth-of-field adjusting unit. The depth-of-field adjusting unit reads, from the image database, a depth of field set beforehand (or designated each time) and image data of images captured from different positions according to user's viewpoints, and outputs the read depth of field and data to an image combining unit. The image combining unit combines a plurality of image data items output from the depth-of-field adjusting unit and displays a combined image on a display. The present invention is applicable to a television apparatus.

摘要： An authentication processing apparatus for performing authentication based on a user's normal operation is provided. The authentication processing apparatus performs the authentication processing on the basis of operation information obtained from normally operating an information processing apparatus. Operation information obtained from operating an input unit by the user, such as a keyboard inputting mode, is obtained to serve as operation information, and the obtained operation information is checked against operation information registered in a database to perform authentication. Authentication is thus made possible without requiring the user to perform the special input processing for the authentication processing. Authentication is performed taking into consideration a plurality of pieces of operation information. With the checking processing in which less dispersed data is weighted, user authentication with high accuracy is made possible.

摘要： An estimation section calculates the motion vector of each pixel and its reliability from two continuous frames, and generates first-order motion distribution images corresponding to the k-th and (k+1)-th frames with any motion vector and reliability being assigned to each pixel. An update section combines the input first-order motion distribution image corresponding to the (k+1)-th frame and the fourth-order motion distribution image corresponding to the (k+1)-th frame generated from the first-order motion distribution image corresponding to the k-th image to generate the second-order motion distribution image corresponding to the (k+1)-th frame. A prediction section generates the third-order motion distribution image corresponding to the (k+2)-th frame according to the input second-order motion distribution image corresponding to the (k+1)-th frame. An interpolation section interpolates into a blank space of the third-order motion distribution image corresponding to the (k+2)-th frame with the use of unbiased estimate to generate the fourth-order motion distribution image corresponding to the (k+2)-th frame.
