The present invention controls to read encrypted digital data from a detachable storage medium, in which the digital data and a decode key for decoding encryption of the digital data are stored. In reading the digital data, the decode key is read, the decode key is deleted from the storage medium, the encrypted digital data is read, and then encryption of the encrypted digital data is decoded by the read decode key.

Storage medium access control method

In a video system of the invention, control means is provided for a terminal input apparatus which is connected by a communication network of a camera on the partner side and which comprises an image display apparatus having a multiwindow display function for selecting and displaying the camera. An image pickup operation which is required to the camera on the partner side, for example, the image pickup direction, focal distance, panning, exposure amount, white balance, automatic focusing, and the like of the designated camera are inputted by using an image display and a window display of the image display apparatus. The operation of the camera on the partner side and the operations of a tripod, a movable arm, and the like to hold the camera are controlled through communicating means. A photographed image is displayed by the display apparatus.

Video system

A recording apparatus includes a recording unit configured to record moving image data including a plurality of frames on a recording medium. The recording medium includes a plurality of clusters. The apparatus also includes an editing unit of the moving image data, a setting unit configured to optionally set the editing unit, a management information processing unit configured to generate management information including link information indicating a cluster number of the moving image data to be reproduced next with respect to a plurality of clusters having the moving image data recorded thereon, and a control unit configured to control the recording unit to record a front frame of each editing unit in the moving image data on an area beginning with a cluster of the recording medium based on the editing unit set by the setting unit.

Recording apparatus for recording data to recording medium with a Plurality of clusters

A data recording system and method are provided which, when the removal of a recording medium is detected during data writing, the data recording system retains accessed processing not executed in the data writing, and executes the retained access processing when the removed recording medium is inserted again into the data system.

Data recording system and data access method

A storage managing system and method, the system and method including matching a boundary of a cluster, which is a minimum data unit of a data region of a storage medium having a write protect function, with a boundary of at least one or more consecutive blocks each having a predetermined size, and applying write protection to data in units of the block.

Storage managing system, storage managing apparatus, and storage managing method

This invention provides a technique that deletes data at high speed, and prevents discontinuous cluster chains from being produced due to data deletion. To accomplish this, when data included in the data file is partially deleted from the head of the data file, the location of header information is moved for respective clusters, and the size of the header information is changed, so as to start head data after data deletion from the location immediately after the moved header information.

Data processing apparatus, data processing method, and data processing program

An image processing apparatus which associates a plurality of images obtained in advance for the purpose of panoramic image synthesis or stereo-scopic viewing display without troubling the user. Whether or not component images are to be associated with each other is determined with reference to the file names and attribute information of a plurality of component images to be synthesized without the intervention of the user.

Image synthesizing system for automatically retrieving and synthesizing images to be synthesized

Apparatus and method for inhibiting control apparatuses from controlling camera when another control apparatus controls camera

Images sensed through object lensesR andL, having zoom lenses, with image sensorsR andL are processed by image signal processorsR andL, and an image of an object in each of the sensed images is separated from a background image on the basis of the processed image signals. The separated image signals representing the image of the object enter the image processor, where a three-dimensional shape of the object is extracted on the basis of parameters used upon sensing the images. The parameters are automatically adjusted so that images of the object fall within the both image sensing areas of the image sensorsR andL and that they fall within the both focal depths of the image sensorsR andL.

An image recognition/reproduction method includes an extraction step of extracting local feature elements of an image, and a selection step of selecting a pair composed of a prescribed local feature element and position information indicative thereof, this pair being such that the distance between a pair composed of a prescribed local feature element and position information indicative thereof and a pair composed of a local feature element extracted at the extraction step and position information indicative thereof is less than a prescribed distance.

Image recognition/reproduction method and apparatus

An image sensing apparatus includes an image input unit () for inputting an image, a detection unit () for detecting a state of movement of the image input unit () in an image input operation, a storage unit () for storing a plurality of images input by the image input unit () and movement information corresponding to the state of movement detected by the detection unit (), and an image generating unit () for generating an image from an arbitrary viewpoint position on the basis of the plurality of images and the movement information stored in the storage unit.

Virtual image sensing and generating method and apparatus

A three-dimensional information processing apparatus for obtaining three-dimensional information from an object having a three-dimensional shape, and performing predetermined information processing, comprises: a camera for sensing images of the object from a plurality of coordinate positions using an image sensing system having one or a plurality of optical systems. A plurality of depth information are extracted from image sensing related information sensed by the camera at the plurality of coordinate positions, and the plurality of extracted depth information are converted and unified into depth information expressed by a unified coordinate system.

Three-dimensional information processing apparatus and method

Images sensed through object lenses R and L, having zoom lenses, with image sensors R and L are processed by image signal processors R and L, and an image of an object in each of the sensed images is separated from a background image on the basis of the processed image signals. The separated image signals representing the image of the object enter the image processor , where a three-dimensional shape of the object is extracted on the basis of parameters used upon sensing the images. The parameters are automatically adjusted so that images of the object fall within the both image sensing areas of the image sensors R and L and that they fall within the both focal depths of the image sensors R and L.

An image processing apparatus in which a plurality of images obtained by photographing a three-dimensional object from a plurality of viewpoints are integrated by using image-pickup parameters such as position, pose, focal lengths, and aberration information of a camera at these viewpoints, thereby integrating shapes at arbitrary viewpoints of the three-dimensional object.
