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.

File access system

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.

Image processing apparatus, image processing method, and computer program product

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.
