Abstract

PURPOSE:To make the operation easy by adding an automatic page turning function when picture information over plural pages is retrieved. CONSTITUTION:When an indication 'automatic page turning' is sent from a keyboard 53, a change-over switch 63 is switched to the second VRAM62 by a change-over control circuit 80 while picture information preserved to the first VRAM61 is read. The second page picture information is written from a light disk to the second VRAM62. Thus, when the new picture information is written to VRAM61 or 62, switches 63 and 64 are changed over, a page turning action is automatically executed, but, the page turning time (display device for one page) can be optionally set by using the keyboard 53.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image information retrieval device that retrieves image information as needed.

[Prior Art] Conventionally, as a device for storing documents as they are and retrieving their image information, there has been a device that reduces and records document images on a Microphone 1 film.

Recently, as an alternative to this, I have been trying to find a way to replace this! There are image information recording and reproducing apparatuses that perform two-dimensional scanning using photoelectric conversion technology using arc light or COD elements. This image information recording and reproducing device decomposes a document image into pixels, converts it into an electrical image signal, and records this image signal at high density on an optical disk recording device or magneto-optical disk recording device. A search device has been developed using this image information recording and reproducing device.

By the way, when recording image information with the above device,
The recording position of the recorded image on the recording medium and so-called search information such as a search code or keyword representing the content of the image information are also recorded on the recording medium such as a magnetic disk. Therefore, if you enter a search code or keyword, the corresponding image information will be searched.
Hard copies are also available for 1q.

In addition, in the above-mentioned conventional device, when recording a plurality of image information and corresponding search information on a recording medium, if the document is set on a two-dimensional scanning device, the image information is almost automatically read and recorded. A device that can be recorded on a medium and that can also register search information is also being considered.

However, when searching for image information, the operator must operate the keys on the keyboard each time, so the more image information there is, the more difficult the search process becomes.
The work is complicated and extremely tiring. In addition, most of the images that are searched are sets that span several pages, and in order to find the desired page in the set, the keys must be pressed again page by page, making the operation even more complicated. , there is a problem that operator fatigue increases further.

[Object of the Invention] The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide an image information retrieval device that is easy to operate when retrieving image information spanning multiple pages. That is.

[Embodiment of the Invention] FIG. 1 is a block diagram showing an embodiment of the present invention.

The reading device 10 reads a document using a predetermined method and converts it into an electrical signal. The optical disk drive device 20 is a device that drives an optical disk having a recording capacity of feldspar. The printer 30 prints document information during reproduction printout. Data bus 41 is a bus that sends image information and search information to predetermined circuits. The control bus 42 is a bus for supplying control signals to predetermined circuits.

The electronic file device main body 50 includes a control circuit 51 and a DMAC.
(Direct memory access controller) 52
It has the following. The control circuit 51 controls the electronic file device main body 50 and peripheral devices, and performs the control in accordance with input contents from the keyboard 53. No. 1 VRAM61. 2nd V RAM 6
2 Get the image information from the optical disc 1
It holds one page. The changeover switch 63 transfers the image information li[ii from the optical disk to the first VRAM 6
The changeover switch 64 selects image information from the first VRAM 61 or the second VRAM 62 and supplies it to the CRT display 70. Note that VRAM is a random access memory for video signals.

The switching control circuit 80 transfers image information from the optical disk to the VRAM 6 by switching the changeover switches 63 and 64.
1 or 62, and C from VRAM61 or 62.
This is used to switch the supply to the RT display 70.

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

First, a description will be given of the platform on which the electronic filing device 1 shown in FIG. 1 records a document.

After setting a predetermined original in the reading device 10, the image information read by the reading device 10 is transferred to the DMAC 52.
After the data is read, the data is transferred to the optical disk drive device 20 via the data bus 41 and recorded on the optical disk. At this time, predetermined search information is input to the control circuit 51 using the keyboard 53, transferred to the optical disk drive device 20 via the data bus 41, and recorded on the optical disk. The above operation is repeated for each document to complete the recording operation. A flowchart of the above operation is shown in FIG.

Next, a case will be described in which image information recorded in an electronic file device is searched.

First, in the case of a search, the selector switch 63.
64 is switched to the first VRAM 61 side (the state shown in FIG. 1).

Then, using the keyboard 53, search information corresponding to the desired document name is input. This search information is stored in the control circuit 51
The target image information is searched for, and the image information for one page is written from the optical disk to the first VRAM 61 via the data bus 41. And this first VR
The CRT display 70 starts scanning (displaying image information) based on the image information written in the AM 61.

As a result, image information for one page is displayed on the CRT display 70.

If the image information spans two or more pages, the following operations are performed. First, the above operation, which is the same as the operation for displaying one page's worth of image information, is performed.

However, in this case, it is displayed on the CRT display 70 that the image information spans multiple pages.

Then, an instruction for "automatic page turning" is sent from the keyboard 53. As a result, while the image information held in the first VRAM 61 is being read, the changeover control circuit 80 switches the changeover switch 63 to the second VRAM 62. Then, the image information of the second page is written from the optical disk to the second VRAM 62. When this writing is completed, the changeover control circuit 80 controls the changeover switch 63.6.
4 are respectively the first VRAM 61. 2nd VRAM62
2 and the second VRAM 62 is read out.
The image information of the third page is displayed on the CRT display 70, and the image information of the third page is written to the first VRAM 61. In this way, new image information is stored in VRAM6.
When written to 1 or 62, switches 63,64 are toggled.

By repeating the above operations, image information up to the last page of the document is sequentially displayed on the CRT display 70.
will be displayed. In other words, the document is automatically "page turned" on the CRT display 70. If the page desired by the user is displayed on the CRT display 70 during this automatic page turning, use the keyboard 53 to select rsTOPJ.
A signal is input and the page turning operation is stopped.

These flowcharts are shown in FIGS. 3 and 4.

Although the page turning operation is performed automatically as described above, the page turning time (display time for one page) may be set arbitrarily (for example, set to 2 seconds or 5 seconds). . The input based on the display time setting is performed using the keyboard 53. And the control circuit 51
By adjusting the switching time performed by the switching control circuit 80 via the page switching control circuit 80, the page turning time can be freely adjusted.

[Effects of the Invention] The present invention has the effect of facilitating the search operation when searching for image information across multiple pages.
