DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image file device that can store a large number of images in a storage medium, and can search and display the stored images as appropriate.

[Conventional technology]

2. Description of the Related Art An image file device has been developed that stores a large number of images in a storage medium such as an optical disk and displays searched images on a display device. In such an image file device, search conditions are input, images matching the search conditions are searched, and the searched images are displayed on a display device. Conventionally, the images of this search result are, for example, 25
In the case of devices that can display up to 25 images on one screen, up to 25 images will be displayed.
If there were 26 or more pieces of a, the screen was further redisplayed.

[Problem that the invention seeks to solve]

For this reason, if there are more images that meet the search conditions than can be displayed on one screen, for example, if there are 26 images in the above case, it is necessary to display them twice. In this way, the number of images displayed as a list of search results is limited to a certain number, and this poses a problem of poor operability, such as the time it takes to view and select an image to consider. On the other hand, when there are only a few images in the search results, the number of divided screens is 25 even though the number of images searched is small, and the images are displayed in a small size, resulting in an unsightly image.

This invention was made in view of the above circumstances,
An object of the present invention is to provide an image file device that can set the number of screen divisions when displaying a plurality of images within one screen according to a search result.

[Means and effects for solving the problem 3 An input means for image data, a storage means for storing the input data,
In an image file device having a search means for searching stored images, a reading means for reading the searched images, and a display means for displaying the searched images, dividing one screen when displaying search result images A means for setting a number N and a means for reducing an image according to the set number N of divisions are provided, and up to N images of search results are displayed side by side on one screen.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings. 1st
The figure is a configuration diagram of an embodiment of the present invention. Information input section 1
allows input of registration search commands, attribute information of images to be registered, and information indicating the number of screen divisions. The image input section 2 is configured to input signals from, for example, a television camera as image data. The controller 3 has a function of receiving commands from the information input section 1 and controlling each section. The frame memory 4 has a function of temporarily storing image data input from the image input section 2. In this embodiment, the number of pixels on one screen is 640 horizontally and 480 vertically. The storage storage section 5 is composed of, for example, an optical disk having a large storage capacity, and is capable of storing image data (images) temporarily stored in the frame memory 4 according to instructions from the controller 3. The display section 6 has the ability to display images stored in the frame memory 4. Reduction part 7a
has a function of reducing the size of the image stored in the storage section 5 and sending it to the frame memory 4.

The list mode storage register 8 is configured to store the number of screen divisions input from the information input section 1 via the controller 3.

In such an image file device, image registration is performed as follows.0 Images input from the image input section 2 are stored in the frame memory 4. When the instruction from the information input section 1 is set to the registration mode according to an operator's instruction, the image stored in the frame memory 4 is sent to the storage section 5 and stored therein. At the time of this registration, the controller 3 stores the attribute information of the registered image and the address of the storage storage section in the attribute information storage section within the controller 3.

Further, the search is performed as follows. The operator inputs search conditions from the information input section 1. Based on the search conditions, the controller 3 searches the attribute information storage unit and selects images that match the search conditions.The search results are stored in the RAM in the controller 3, for example, as shown in Table 1.
(random access memory) is stored in a search result storage table. This example shows that, for example, five images are applicable, and the storage addresses of the applicable images in the storage unit 5 are stored together with the order.

Table 1 The controller 3 displays on the display section provided in the information input section 1 that there are five images matching the search results.

Seeing this, the operator decided that the number of screen divisions was 4.16.64.
It is possible to select appropriate information from among them and input the information from the information input section 1. for example,
When the operator selects the number of divisions 4, the information on the number of divisions 4 is stored in the list mode and stored on the disk 8. The controller 3 reads the value 4 stored in the list mode storage register 8 and instructs the reduction unit 7a to reduce the value to 174. Then, the controller 3 instructs to read the image stored at address 1002 of the accumulation storage section 5.

This image is reduced to 174 pixels by the reduction unit 7a and stored at a predetermined position in the frame memory 4. frame memory 4
The arrangement of the divided images within is as shown in FIG.

In other words, the storage coordinates (X, Y> of the four images are the first image (
The pi mark of the starting point of (first) is (0,0) and below (320,
0), (0,240).

(320, 240), indicating that it can be divided into four areas E1 to E4.

The image reduced to 1/4 is transferred to an area E1 of 320 x 240 pixels starting at the coordinates (0, O) of the frame memory 4 and displayed at the corresponding position on the display unit 6. Further, the second image stored from the address 1260 of the accumulation storage unit 5 is stored in the area E2, and the third and fourth images are stored in the area E3. E4 and displayed at the corresponding position on the display section 6. Furthermore, in order to display the fifth image, information instructing the next display is input from the information input section 1. Then, the frame memory 4 is cleared, and the fifth image is stored in the area E1 and displayed.

In the above case, since the images of the search results cannot be viewed at a glance, the number of divisions of one screen, 16, is selected and input from the information input section 1. Then, the controller 3 changes the contents of the list mode storage register 8 and gives a 1/16 reduction instruction to the reduction m1a. The storage coordinates in the frame memory 4 are set as shown in FIG. 3, and 16 areas E1 to E16 are formed.

Then, images No. 1 to 5 of the search results are areas E1 to E.
5 and displayed at the corresponding position on the display section 6.

In this case, - all images of the search results can be displayed on the screen.

In this way, the number of divisions can be selected as appropriate.

FIG. 4 is a block diagram showing another embodiment of the present invention. The difference between this embodiment and the embodiment shown in FIG. 1 is as follows.
It is controlled by the controller 3, and the reduction section 7a is not provided, but the reduction section 7a is provided on the side that sends data from the frame memory 4 to the storage storage section 5.

In this embodiment, as in the previous embodiment, the number of screen divisions is 4.
There are three options available: 16.64. At the time of registration, according to instructions from the controller 3, the image stored in the frame memory 4 is first converted to MM without being reduced.
It is stored in the i storage section 5. Subsequently, the controller 3 gives a command to the reduction section 7a to record the image reduced to 1/4 in the storage section 5. Similarly, 1/16.1/64
The reduced image is stored in the accumulation storage section 5.

As an example of the search, a case will be described in which, for example, five corresponding images are extracted. This search result is shown in Table 2, for example.
The search results are stored in the search result storage table in the controller 3 as shown in FIG. That is, for each extracted image,
This shows that the storage addresses of the reduced images of 1/1 (original image) and 1/4.1/16.1/64 in the accumulation storage unit 5 are stored in correspondence with each other.

Table 2 Therefore, when the number of screen divisions is 16, the image already reduced to 1716 stored from Luatres 1152.1410.1585°2674, 3013 in the storage storage unit 5 is stored in the frame memory shown in FIG. 4 are stored and displayed in areas E1 to E5.

In the case of this embodiment, since reduced images are also stored in the accumulation storage section 5, display at the time of retrieval can be performed very quickly.

FIG. 5 is a diagram showing still another embodiment of the present invention. This embodiment is characterized in that it has a reduction ratio determination section 9 instead of the list mode storage register 8 in the embodiment shown in FIG. This reduction ratio determining section 9 has a function of selecting the reduction ratio of images according to the number of search results.

The operation at the time of registration is similar to the embodiment shown in FIG. When searching, the images extracted as a result of the search (numbers 1 to 4)
When the image size is 1/4, the reduction ratio determining section 9 under the control of the controller 3 determines the reduction ratio to be 1/4. Then, the controller 3 instructs the reduction unit 7a to reduce the image by 1/4. Therefore, all images of the search results are displayed on the screen divided into four parts. The number of search results is 5 or more
When the number of images is 1.6, the image is reduced by 1716, and when it is larger than that, the image is reduced by 1/64 and displayed on the screen.

Therefore, in this embodiment, more images of search results can be displayed on one screen with higher resolution. Note that if the reduction ratio of the image can be arbitrarily selected, the reduction ratio can be determined more precisely, and an image of a more suitable size can be displayed.

〔Effect of the invention〕

As described above, according to the present invention, - the number of screen divisions when displaying multiple images on the screen can be set according to the search results, so the list of search results can be displayed efficiently; Can be done.
