First, the code reading unit 402 reads the document code information from the code storage unit 401.

The data extraction unit 405 extracts graphic data from the document code information read by the code reading unit 402 in the order of rectangle, rounded square, and ellipse.

The replacement data generation unit 408 stores the rectangle in the rough image storage unit 409 because the replacement flag is off because the rectangle does not take much time to display.

Since the rounded square takes a long time to display, the replacement flag is turned off to store the data in the replacement image storage unit 410, and the rectangle is used as the rough image, and the rectangular data is generated and replaced. The flag is turned on and stored in the schematic image storage unit 409. Similarly, an ellipse is approximated by a straight line figure.

The drawing unit 406 receives the data stored in the schematic image storage unit 409, generates data corresponding to the display on the screen, and writes the data in the display memory 403.

At this point, the display device 404 displays a display as shown in FIG. Subsequently, the replacement drawing unit 411 reads out the data from the replacement image storage unit 410, deletes the data of the approximate figure to be replaced whose replacement flag is ON, and displays the rounded squares and ellipses as the replacement data. The contents of the display memory 403 are changed to.

At this point, the display device 404 displays a display as shown in FIG. Such processing is performed within a predetermined time range, and when the predetermined time elapses, the display of this document ends and the display of the next document starts.

That is, the display at low speed is displayed as shown in FIG. 30, and the display at high speed is displayed as shown in FIG.

As described above, according to the invention of claim 4, even in the case of a document including graphic data, a rough image can be produced in a short time, and the whole image can be grasped even when performing fast page turning. In case of slow page turning, you can get high quality images,
The search efficiency can be increased more than the invention of claim 1.

In this embodiment, a rectangle, a rounded square,
Although the data was extracted in the order of ellipses, more attributes may actually be used, or they may be extracted in a different order. Further, although a rectangle is assigned to the rounded square as a schematic image, another approximate figure may be assigned, or the rounded square may be drawn without assigning the approximate figure. that's all,
Although the invention of each claim has been described based on the embodiments, it goes without saying that the invention of each claim is not limited to the above embodiments. That is, for example, in each embodiment,
Although the display on the display device is also described in the flowchart, the display on the display device may be performed by always reflecting the contents of the image memory in real time independently of the flow.

In each of the embodiments, it is checked on the flow whether or not the predetermined time has elapsed, but a timer may be provided separately to notify the elapse of the predetermined time by interruption.

For convenience of manufacture, production, design, etc., each component of the image retrieval apparatus according to the present invention may be divided into a plurality of components in terms of hardware or software, or conversely, a plurality of components may be integrated. May be.

[0076]

As described above, according to the first aspect of the present invention, the data extraction unit for extracting the data of the specific attribute is provided, and the more easily recognizable data is displayed first, the document Even when performing fast page turning that cannot display all data, the search points such as titles and headings can be displayed without fail, and search efficiency can be improved.

According to the second aspect of the invention, the display contents of each page-turned document are the same at the attribute level, and the display quality of each document is uniform, so that an image that is easy to see when performing a page-turning search is obtained. More than the invention of claim 1,
It is possible to improve the search efficiency.

According to the third aspect of the present invention, by displaying the document layout, it becomes easy to grasp the appearance of the document at the time of performing high-speed page turning, and the format and column are set even when performing page turning at high speed. Since the layout information such as can be used for the search, the search efficiency can be improved more than the invention according to claim 1.

According to the invention of claim 4, even in the case of a document including graphic data, a rough image can be produced in a short time, and the whole image can be grasped even when performing high-speed page turning. In case of page turning,
A high-quality image can be obtained, and the search efficiency can be increased more than the invention of claim 1.
