摘要:
A server that manages a distribution of a file and at least two client devices including a first client device that requests the file and a second client device that transfers the file are connected via a network. The second client device includes a storing unit to store the file, and a transferring unit that transfers the file to the first client device. The server includes a managing unit that manages the file, a distributing unit that distributes the file in response to a request from the first client device, and a reward managing unit that manages a reward for the second client device that participated in a transfer of the file.

In an image processing apparatus, an encoding unit encodes a processed image; a determining unit determines whether a reference pixel has been subjected to the image processing; and a decoding unit decodes, when the determining unit determines that the reference pixel has been subjected to the image processing, a piece of rectangular block code data of a rectangular block thereby acquiring a second decoded image. The encoding unit refers to, when the determining unit determines that the reference pixel has been subjected to the image processing, the processed image and encodes the second decoded image.

A disclosed image display apparatus for displaying multiple images on a single screen includes a magnification unit configured to, in response to a zooming operation on the screen, magnify distances between centroids of first group images included in the multiple images and magnify the first group images; and a display control unit configured to display in a space of the magnified distances one or more images different from the multiple images. A magnification rate of the distances between the centroids has a nonlinear relationship to a magnification rate of the first group images, and within an extent of the nonlinear relationship, the magnification rate of the distances between the centroids has a predetermined range in which the magnification rate of the first group images is larger than the magnification rate of the distances between the centroids.

An image retrieval system that provides secured image data in response to a query specified by a user. The system includes a data retrieval unit, an encryption unit, and an output unit. The data retrieval unit is configured to retrieve image data relevant to the specified query from a collection of image data. The encryption unit is configured to encrypt at least a portion of the retrieved image data according to the specified query. The output unit is configured to output the at least partially encrypted image data to the user. The image data represents an image formed of one or more regions each having a keyword associated therewith. The encrypted portion is decryptable by the user only when the user is authorized to view the entire image.

A first data storing unit stores therein first data required for displaying an image in a drawing window. Upon a mode switching unit switching a display mode in the drawing window, a data acquiring unit acquires auxiliary data required for displaying the image in a switched display mode from the first data storing unit. A data generating unit generates image data required for displaying the image in the switched display mode using the auxiliary data. A displaying unit displays thereon the image in the switched display mode in drawing window using the image data generated by the data generating unit.

A disclosed file access system is capable of receiving each of code data from a server apparatus and updating a local file without increasing the processing time upon receiving the code data as the number of received code data is increased. The file access system includes a header data receiving unit receiving header data; a header data writing unit writing the header data into the local file; a code data receiving unit receiving designated code data from among the code data; a storage area allocating unit allocating a storage area with respect to the local file so that the code data received by the code data receiving unit can be written from the same starting position of the local file as that of the original file; and a code data writing unit writing the code data from the position of the local file.

摘要:
An attribute determining unit determines an attribute of image data of an image. A still-image extracting unit extracts, when the attribute is a moving image, a still image from the image data. A feature-amount obtaining unit obtains a feature amount from image data of the still image and image data of a still image when the attribute is the still image. An arrangement-position determining unit determines an arrangement position of a display area based on the feature amount. A display-image generating unit generates a thumbnail image from the still image and displays a list of thumbnail images in the display area, based on the arrangement position and the display area.
