Abstract

PURPOSE:To equalize the data display time at the time of the retrieval of data by setting the reference data for switching display methods and displaying the information showing the contents of the image data having the information quantity larger than the reference data at the retrieval of data. CONSTITUTION:The data on the next processing object page are read out of an auxiliary storage 4, and the image size of the data on the processing object page is compared with the data size of the reference value stored in a storage 3. When the image size is larger than the reference value, the image information on the processing object page is edited and displayed on a display device 6. Thus, an extremely long time is not required for a part including a large quantity of the data. Then the time required for a single display operation of the image data can be equalized at the time of the retrieval of the data.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing system that handles image data including text, graphics, and image data, and particularly relates to a method for searching image data.

[Prior Art] Conventionally, an image data search method for searching for image data located at a specific location is as described in JP-A-63-85925, for example, in which data desired by an operator is found,
The method used was to display image data one after another for each page until the search was stopped by the operator.

[Problems to be Solved by the Invention] The above-mentioned conventional technology does not take into account the change in display time due to the difference in the amount of image data in the display range of - times,
If there is data with a high resolution or large data size in an image file, it will take time to display that part of the data, making it difficult for the operator to find the desired data. There is a problem in that the time required is extremely long and the burden on the operator becomes heavy.

An object of the present invention is to make the display time for one screen of data the same when searching for specific data, to shorten the time it takes for an operator to find the desired data, and to facilitate easy-to-use image search. The purpose is to provide a method.

[Means for solving the problem] In order to achieve the above purpose, when storing and storing image data, for each display range, identification information such as image size and resolution indicating the amount of data in that range, and the range information indicating the content of the image data (such as a summary of the image data) is stored, and when searching, the format of the standard data to be displayed is set in advance. For image data with a small amount, the image data is displayed as it is on the display device, and for data that has a larger amount of information than the reference data, information indicating the content of the data is displayed on the display device.

Furthermore, if you want to display image data that has more information than the reference data, you can display that image data by making a display request using the input device while information indicating the content of that data is being displayed on the display device. It has an auxiliary search function displayed on the device.

[Effect] Sets reference data as a guide for switching the display method,
For image data that has a larger amount of information than the reference data during a search, by displaying information indicating the content of that image data, it will not take time to display data with a large amount of information, and the data display time during a search will be reduced. can be made uniform.

Furthermore, if the reference data is set to the minimum value, information indicating the contents of the image data will be sequentially displayed on the display device, and data can be searched using that information. By maximizing the reference data, all image data can be displayed on the display device.

[Example] Hereinafter, an example of the present invention will be described in detail using the drawings.

It is.

FIG. 2 is a configuration diagram of one of the image files stored in the auxiliary storage device 4, which consists of one image data 11 and a header portion. The header includes each page number 7 (1 to n) of the image file, the image size 8 (A3 version, A4 version, etc.) of the image data of the corresponding page, the resolution 9 of the image data of the corresponding page, and the image data of the corresponding page. It includes image information such as comment text 10 indicating the content.

FIG. 1 is a flowchart of the search processing procedure of this embodiment, and the present embodiment will be described below based on FIG. 1.

In this embodiment, the method of displaying image data when searching for data is a method of sequentially displaying data in one image file starting from the page specified by the operator.

First, in order to set initial values for searching, an initial value setting screen is displayed on the display device and waits for the operator's input (101
), the initial value is the interval time when image data is displayed sequentially, the selection of whether to measure the interval time from the start of display on the screen or the end of display, and the image file stored in the auxiliary storage device 4. Specify the file name of which file to search, reference values including data size and resolution to control display (for example, data with size A3 or larger or resolution 400 dpi or larger), and start of search. Pages, etc. The above settings are input by the operator from the input device 5 and stored in the storage device 3 (102).
However, the display interval time, reference value, etc. may be set in advance in the program.

Next, the data of the page to be processed is read from the auxiliary storage device 4 (103), and the amount of information of the image data of that page is
It is determined whether the value is within the reference value set in step 101. First, compare the image size 8 in the header part of the data of the page to be processed with the data size of the standard value stored in the storage device 3 (104). If the image size of the page to be processed is larger than the standard value, the image size of the page to be processed is Edit the image information and display it on the display device (108). If it is smaller than the standard value, compare the resolution in the same way as data size comparison (105). If the resolution is smaller than the standard value, use the image data of the page to be processed as is. If the image information of the page to be processed is large, the image information of the page to be processed is edited and displayed on the display device 6 (108).Here, the data of the page to be processed is directly read from the auxiliary storage device 4, but All or part of the information may be temporarily stored in the storage device 3 and then read out from the storage device 3.

FIG. 3 shows an example of image data displayed on the display device in step 106, and FIG. 4 shows an example of image information displayed on the display device in step 108.
FIG. 5 is a diagram showing image data corresponding to when an image display request is input in step 110 while the screen of FIG. 4 is being displayed. In FIG. 4, if an explanatory text such as ``Press key X if you want to see the data of this image'' is displayed, it is expected that the operability will be further improved. If the reference value is set to size AS and resolution to 400 dpi, the image data in Figure 3 is, for example, A4, 200 dpi.
The image data in Figure 5 is A3,400dp.
This is image data of i.

When the image of the page to be processed is displayed in step 106 or step 108, an input from the input device 5 is waited for the display interval time set in step 101. It is determined whether or not an image display request is input while displaying image information within the display interval time (108) (110), and if input, the corresponding image data is displayed on the display device (106). If there is no input, the display waits for the display interval time to elapse. Similarly, it is determined whether or not a search stop command has been input from the input device 5 during the display interval time (111), and if it has been input, the search process is terminated. If a search stop command has not been input, it is determined whether the data displayed as 1 is the last page (112), and if it is the last page, the search is terminated. If it is not the last page, set the next page as the page to be processed 113
), the process returns to step 103 and continues the search process until the operator inputs a command to stop the search or until the final page is displayed.

Furthermore, in this embodiment, if a certain degree of judgment can be made by looking only at the image information, if the data that is the standard for displaying the initial value is set to the minimum value, only the image information will be displayed sequentially. After looking at the image information, the operator can display and search only the image data that he or she wants to see.

As described above, according to this embodiment, when searching for an image file in which the amount of data information is not constant, it is possible to avoid unnecessary time being spent displaying pages that do not contain the desired data and have a large amount of data. This allows for more efficient search work.

[Effects of the Invention] When searching for an image file in which the amount of information in the data is not constant, the present invention allows only information indicating the content of the data to be displayed on the display device for data that has a larger amount of information than the reference data. By displaying the image data, it will not take a significant amount of time to display parts with a large amount of data, so the time taken to display image data once during a search can be equalized, reducing search time. becomes.

Further, when only information indicating the content of data is displayed, if a display request is made from the input device 5, that data can be displayed, so that the desired data can be efficiently searched.
