Abstract

PURPOSE:To designate quickly an aimed picture by plural pairs of the reduced picture of pictures to be retrieved and the retrieving auxiliary information composed mainly of characters at retrieving. CONSTITUTION:When respective picture data are stored in a memory means 2, the data are stored in the order of 1) the retrieving auxiliary information composed mainly of the character, 2) the part used with the high frequency out of the reduced picture data, 3) the remaining part of the reduced picture data and 4) the information to supplement the assembly of the above-mentioned 2) and 3) and reload the picture. At the time of retrieving the picture, reading is executed from a memory means 2 to 2) or 3) by a control means 3, and plural pairs of the reduced picture and the retrieving auxiliary information are displayed at a bit map system displaying means 1. When one pair out of them is selected by an indicating means 4, the control means 3 writes in a dispersed way respective bits of 2) and 3) of the selected picture, and next, between them, 4) is written, and thereby, the original picture is reloaded and displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides, when searching stored image information, prior to displaying the image to be searched, a reduced image of the stored image and mainly characters. The present invention relates to an image search device U that enables quick designation of a target image by displaying search auxiliary information.

BACKGROUND OF THE INVENTION In most conventional image searches, the registration date of an image or a keyword representing the content of an image is used as a search means.

Also, for example, the 28th Information Processing Society of Japan
l) As reported in National Conference 5C-1, it is also proposed to store and manage reduced images as data separately from the searched image, or to search by reducing and displaying the searched image at the time of search. has been done.

Problem to be Solved by the Invention However, the amount of information contained in keywords, etc. is overwhelmingly smaller than that of images, and as the amount of accumulated image information increases, it becomes difficult to identify the desired image, and the searched image itself becomes difficult to identify. The search is forced to be a trial-and-error process, with the user noticing the error until the page is displayed.

Furthermore, the conventional method of using reduced image data for searching has the problem that one of the following is sacrificed: storage storage capacity, buffer storage capacity, display speed of searched images, or display speed of reduced images.

In view of the above, the present invention displays a plurality of sets of a reduced image of a searched image and search auxiliary information at the time of a search, without requiring duplicate data or unreasonably large buffer storage, and displays one set of them as an instruction means. The object of the present invention is to provide an image retrieval device that can perform retrieval by giving instructions using .

Means for Solving the Problems The image retrieval device according to the present invention has separate memories for each bit.
A bit map type display means for n-bit parallel writing consisting of a chip, a storage means for storing data according to a storage format consisting of search auxiliary information, high-frequency reduced images, low-frequency reduced images, and supplementary information, and a storage means to be searched from the stored data. control means for reproducing the image, its 1/n reduced image, and search auxiliary information;
/n reduced images can both be displayed at high speed. The present invention is further provided with an instruction means for specifying an image to be displayed from among the plurality of sets of search auxiliary information and 1/n reduced images displayed for search.

Function When storing each image data, 1) search auxiliary information consisting mainly of characters, 2) a reduced image consisting of a group of bits extracted at a rate of 1 bit for every n bits from the data composing the searched image. , a frequently used part, 3) the remaining part of the same reduced image, and 4) information for restoring the searched image by complementing the combination of 2) and 3). The sum of the information amounts in 2), 3), and 4) is equal to the bit image m of the image to be searched.

According to this data format, when displaying a reduced image, it is sufficient to read steps 2) or 3) from the storage means. When displaying the searched image, first 2), 3)
discretely write each bit of , and then write 4) in between. These operations are accomplished by the control means as follows, without the need for time-consuming operations such as repeated bit extraction and shifting.

The control means is equipped with an address conversion function for each memory chip as part of the control means.1) When displaying a reduced image, the same address is given to all memory chips, and when writing each bit discretely in 2) and 3), All different addresses are given to each memory chip, and when writing 4), one of two addresses that differ by one address is given to each memory chip.

Since the address translation function described above can be realized by combinatorial U logic, no storage elements are required.

Embodiment 4 A card image as shown in FIG. 2 is displayed using a bit map type display means with bit parallel writing, and puff aisle 2'' is selected on this screen by an instruction means such as a mouse, tablet, or light ben. Then, the searched image puff aisle 2'' is displayed in its original size.

Puff aisle 2'° shown in FIG. 2 is a reduced image of 1/4 of its original size.

Each file is saved according to the data format shown in FIG. That is, the search auxiliary information is at the beginning, followed by the frequently reduced images. In order to display the image shown in FIG. 2, it is sufficient to read up to the high-frequency reduced images for the puff aisle 2''.

In the illustrated example, the character string ``puff file 2'' is stored at the end as search auxiliary information, but in order to display this, it is necessary to specify the display position in addition to the size and writing direction of the characters. This display position (Xa, Ya) is generally a function of the image position (Xi, Yi) and an integer n indicating the number of images from the front, as follows: Xa = f (Xi, Yi, n) Ya = g
(Xi, Yi, n) Therefore, f and O are included as search auxiliary information.

Also, ``File 2'' is ``File 1'' in Figure 2.
When the card is at the front of the card group, as in '°, even low-frequency reduced images are read and displayed.

That is, when the image information to be displayed is the first image, the high-frequency reduced image and the low-frequency reduced image are used, and when it is the second or subsequent image, only the high-frequency reduced image is used.

Now, the puff file 2'' that has been reduced and displayed in this way is selected and is called ``file B'', but in this case, all data including supplementary information is required. , 4 bits are written in parallel, so one word of the reduced image is structured as shown in Figure 4 a),
This is expanded into 42 words as shown in b) of the same figure, and supplemented with complementary information to restore the original image. However, since the second, third, and fourth rows are complementary information itself, each bit of the reduced image is first discretely written into each word of the first column by the address conversion function of the control means. Then, there is a gap of exactly one word, so the address conversion function is used to write complementary information there.

In this way, the image to be searched can be restored and displayed at approximately the same speed as in the conventional case where reduced image data and image data to be searched are stored separately.

In Fig. 4, we call the insertion between ■ and ■ interpolation 0, the writing between ■ and ■ interpolation 1, and the writing between ■ and 0 interpolation 2. This is necessary in this example. The address translation functions are summarized for each memory chip as shown in FIG.

Therefore, as shown in FIG. 6, it is preferable to provide an address adder for each memory chip and perform addition to the reference address depending on the type of writing.

Effects of the Invention The image search device of the present invention provides users with more information more quickly in an easier-to-receive format when searching for images, which not only dramatically improves image search efficiency but also avoids data duplication. You can avoid waste of storage.
