Description

本発明のデータ処理装置は、外部のメモリにおいて階層構造で管理されているデータを処理するデータ処理装置であって、表示画面への表示対象になっている、前記階層構造で管理されている第１のデータから、前記階層構造で管理されている第２のデータを表示させるまでの前記階層構造における操作ステップの数を、前記階層構造に基づいて取得する取得手段と、前記階層構造で管理されている複数の第２のデータのそれぞれについて前記取得手段により取得された操作ステップ数に基づいて、前記複数の第２のデータのうちの、前記表示画面への表示対象となる前に前記外部のメモリから読み込んでキャッシュ領域に保存させるデータを決定する決定手段と、を有することを特徴とする。 A data processing apparatus according to the present invention is a data processing apparatus that processes data managed in a hierarchical structure in an external memory, and is the first managed in the hierarchical structure that is to be displayed on a display screen. Acquisition means for acquiring, based on the hierarchical structure, the number of operation steps in the hierarchical structure from displaying the first data to displaying the second data managed in the hierarchical structure; Based on the number of operation steps acquired by the acquisition unit for each of the plurality of second data, the external data before being the display target on the display screen of the plurality of second data. And determining means for determining data to be read from the memory and stored in the cache area.

Claims

A data processing apparatus for processing data managed in a hierarchical structure in an external memory ,
The number of operating steps in the hierarchical structure are eligible to appear on the display screen, the first data are managed by the hierarchical structure, before displaying the second data managed by the hierarchical structure Obtaining means for obtaining the information based on the hierarchical structure ;
Based on the number of operation steps acquired by the acquisition unit for each of the plurality of second data managed in the hierarchical structure, the display target on the display screen of the plurality of second data determining means for determining the data to be stored in the cache area read from the external memory before it,
A data processing apparatus comprising:

It said determining means, the data processing apparatus according to claim 1, wherein the determining of the plurality of data already stored in the cache area, the data of the target to be deleted from the cache area.

Said determining means out of said plurality of data which is newly stored are candidates in the cache area, according to claim 1, wherein the determining the target data to be newly stored in the cache area Data processing device.

4. The data processing apparatus according to claim 1, wherein the data managed in the hierarchical structure is at least one of image data, an image file, and a document file. 5.

Said external memory, said data processing memory card mounted on the device or data processing device according to any one of claims 1 to 4, characterized in that a server going through the network.

The data managed in the hierarchical structure is data managed in at least one kind of group among folders, file creation years, file creation months, and file creation dates. The data processing apparatus according to any one of 1 to 5.

Said determining means, among the plurality of second data is a candidate to be stored in the cache area, said operating step number determining less data than a predetermined number as data to be stored in the cache area The data processing apparatus according to claim 1, wherein the data processing apparatus is a data processing apparatus.

The determination means determines the data having a smaller number of operation steps as data to be stored in the cache area by comparing the number of operation steps between a plurality of second data that are candidates to be stored in the cache area. The data processing apparatus according to claim 7, wherein:

In response to a predetermined operation is performed by the user, the data of the display target data in the same layer of data as a display target in the hierarchical structure or the upper layer of the data as a display target, Switching means for switching to the data of
Said acquisition means, to any one of claims 1 to 8, characterized in that the switching of the display target by the switching means and the predetermined data to obtain the number of the predetermined operation to be displayed The data processing apparatus described.

The data processing apparatus according to any one of claims 1 to 9, wherein data managed in a hierarchical structure in the external memory is displayed.

10. The data processing apparatus according to claim 1, wherein data managed in a hierarchical structure is printed in the external memory.

A data processing method for processing data managed in a hierarchical structure in an external memory,
  The number of operation steps in the hierarchical structure from the first data managed in the hierarchical structure, which is the display target on the display screen, to displaying the second data managed in the hierarchical structure Acquiring step based on the hierarchical structure;
  Based on the number of operation steps acquired in the acquisition step for each of the plurality of second data managed in the hierarchical structure, the display target on the display screen of the plurality of second data A determination step of determining data to be read from the external memory and stored in the cache area before
  A data processing method characterized by comprising:

The program for functioning a computer as each means of the data processor of any one of Claims 1 thru | or 11 .
