Description

The present invention relates to a control device for an image reading apparatus.

[Prior Art] A conventional electronic file system with a microfilm scanner searches predetermined data from a predetermined database,
It suffices to read the image corresponding to the retrieved data from the microfilm scanner.

In this case, the image read by the microfilm scanner has almost the same density as that of the microfilm, but depending on the case, there is a demand to change the density and display it on a CRT or output it by a printer.

Also, when displaying on a CRT or when outputting with a printer, similarly, there is a request to output the above-mentioned image in a size different from usual.

[Object of the Invention] It is an object of the present invention to provide a control device for an image reading apparatus in which an operation of setting a reading condition by an operator is reduced as much as possible and an image in an appropriate state is always obtained.

That is, the present invention is, in a control device for controlling a reading device that reads an image recorded on a film-shaped recording medium, reads search data and an image for searching a desired image recorded on the film-shaped recording medium. Corresponds to a database in which a plurality of records composed of conditions are registered, a search unit for searching records in the database to read a desired image from a film-shaped recording medium, and a record searched by this search unit. Setting means for setting the reading conditions when the reading device reads the image to be read,
The reading condition set by the setting unit is registered in the database as record data.

Embodiment of the Invention FIG. 1 is a diagram showing an example of the present invention.

The microfilm scanner 1 can read each frame of microfilm in a designated size and density. Optical disc and optical disc controller 2
Is for storing image data.

In addition to this, a printer 5 for printing image data
A scanner 6 for reading image data such as photographs, a high-resolution display 7 for displaying the read image data, a keyboard 8, a pointing device 9,
It has a controller 3 for controlling these peripheral devices as a whole and a search database storage hard disk 4 in the controller 3.

In addition, the controller 3 is the microfilm scanner 1
This is an example of changing the density or size of the image when reading the image from, and storing the changed density or size in the database. The size referred to here is the original size of the microfilm image or the size at the time of outputting.

FIG. 2 is a diagram showing the relationship between the microfilm and the search database file stored in the hard disk 4.

One record 15 of the search database file 14 corresponds to each frame 12 and 13 in the microfilm 11. Further, reference numerals 16, 17, and 18 shown in FIG. 2 are storage fields of keywords required when registering each frame in the search database.

Next, the operation of the above embodiment will be described.

FIG. 6 is a flowchart showing the operation of registering the density and size of image data in the search database file in the above embodiment.

A designation window (this example is shown in FIG. 3) for designating the density and size when reading the image data is displayed on the high resolution display (hereinafter referred to as “CRT”) 7. Then, the density and size of the image are designated by the keyboard 8 or the pointing device 9 (S11).

Next, according to the designated density and size, a predetermined frame is read from the microfilm scanner 1 and displayed on the CRT 7 (S12). On CRT7 (printer 5 if needed
2) Output the image data and check the density and size.

If you want to change the size or density at this time (S1
3) Return to S11. When it is not necessary to change the density and size, a keyword or the like corresponding to the image data is input using the keyboard 8 and the pointing device 9 (S14). Then, information such as the current keyword, density, and size is registered as one record in the search database file (S15). That is, if the density or size of the image has been changed, the changed density or size is registered in the database.

An example of the record format of the search database file at this time is shown in FIG. Where the sign
Reference numerals 21, 22 and 23 indicate storage fields for the input keyword. In practice, the number of keyword fields varies from system to system. Also, reference numeral 24 is the size,
Reference numeral 25 is a density, and reference numeral 26 is a storage field of a microfilm number and a frame number.

FIG. 7 is a flow chart showing the operation of changing the density and size in reading the image data at the time of retrieval in the above embodiment.

First, using the key dovo 8 or the pointing device 9, the search condition of the search database is input to search the search database file (S21).

The search result is displayed on the CRT 7 (this example is shown in FIG. 5), and the record corresponding to the image data to be read is designated from the search result by the keyboard 8 or the pointing device 9 (S22). .

According to the density and size stored in the record of the search database file, the image data corresponding to the above instruction is read from the microfilm scanner 1 and displayed on the CRT 7 (S23).

Here, the image data is output to the CRT 7 (to the printer 5 if necessary), and the density and size are confirmed (S2
Four).

If you want to change the density or size, read the image data shown in Fig. 3 and enter the specified density and size window.
The image is displayed on the CRT 7 and the density or size is changed with the keyboard or the pointing device 9 (S25).
Next, based on the changed density or size, the image data is read again from the microfilm scanner 1,
Display on CRT7 (S26). If the size or density needs to be changed again (S27), the process returns to S25.

When it is no longer necessary to change the density or size, the already changed density and size are written in a predetermined record of the search database file, and the process ends.

This allows the density or size to be changed at any time regardless of the initially set density or size.

Note that either the density or the size of the image may be changed, or both of them may be changed at the same time.

Further, by changing the image density data and changing the resolution at the time of reading, it is possible to change the resolution and display or print.

Further, the size of the image may be the reduction ratio of the microfilm.

EFFECTS OF THE INVENTION According to the present invention, an image can be read from a film-shaped recording medium according to the reading conditions in a record registered in a database, and if the read image is not in a desired state, Since the reading conditions can be changed and re-registered as the data of the record, the operability at the time of the next search and reading is improved, and an image in an appropriate state can be obtained at all times.
