[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a search screen display control system for searching and displaying a large amount of accumulated image data such as an electronic file device, and more particularly, to efficiently search for an image by turning a page. The present invention relates to a search screen display control system suitable for.

[0002]

2. Description of the Related Art In recent years, digitization of images has been advanced, and for example, pages 1882 to 1883 of "Electronic Information and Communication Handbook" edited by The Institute of Electronics, Information and Communication Engineers (1988, published by Ohmsha Co., Ltd.), and , 27th
A large-capacity image search device such as an electronic file device using an optical disk described on page 17 has been put to practical use. In a device that has accumulated such a large amount of images, it is important that the desired image can be searched quickly and accurately in addition to being able to easily input.

[0003] In a search for a magazine or a book, generally, a desired content can be obtained by selecting a page in which the desired content is described from a table of contents or an index. It is also practiced to browse the first page to the last page without using the table of contents to obtain the target page.
On the other hand, using a computer, a large amount of image data accumulated on an optical disk or the like is converted into a CRT (Cathode Ra
For electronic file devices that display screens on display devices such as y tubes and cathode ray tubes, databases, and center-end type information provision terminals, the card format that handles the screens as one card, and the card and card A method of managing relationships by connecting them in a tree structure is adopted.

Conventionally, in this type of apparatus, the image data from the storage device is stored in one page based on the page turning operation by the operator.
Since pages or pages were read out one by one and displayed on the display device, it took a long time to search and was not necessarily an easy-to-use device in a device that accumulated a large amount of image data. Further, in an apparatus in which an operator obtains a target image while continuously displaying image data at high speed, the operator instructs to stop when the target image is displayed, but the screen is not switched. The operation speed is high and the operation of the stop instruction by the operator is delayed, or the input of the stop instruction signal is delayed due to poor response performance of the device. As a result, the image data that is stopped and displayed will pass the target image against the operator's will. In such a case, the operator returns the display screens back one by one by repeating the key operation to display the target image.

[0005]

The problem to be solved by the prior art is that, in the prior art, when the operator inputs a stop instruction at a delay when searching for image data whose display screen is switched at high speed, the operation is performed. The point is that the person must repeat the key operation for returning the display screens one by one in order to obtain the display screen of the desired image data. An object of the present invention is to solve these problems of the prior art, reduce the operation load from the high-speed screen switching stop instruction to obtain the target image data display screen, and increase the speed, thereby improving the operation performance related to the search. It is to provide a search screen display control system capable of improving the search.

It is characterized in that a display portion is provided. (2) In the search screen display control system described in (1) above, the list display unit is characterized in that a reduced screen of each image data is two-dimensionally arranged to form a list screen. (3) In the search screen display control system according to (1) or (2), the corresponding image data is selected based on the operator's selection designation for the reduced screen in the list screen. Then, a specific screen display unit is provided for switching the list screen to display only the selected image data. Also,
(4) In the search screen display control system according to any one of (1) to (3), the list display unit displays the image data at the time of inputting the stop instruction after the switching of the screen display based on the stop instruction input is stopped. , And generation of a reduced screen of image data of a predetermined page displayed before this image data is collectively performed. (5) In the search screen display control system according to any one of (1) to (3), the list display unit newly creates a corresponding reduced screen every time the screen is switched at a predetermined time interval. It is characterized in that it is generated and the constituent contents of the list screen are sequentially updated.

[0007]

In the present invention, when the operator gives an instruction to stop the screen switching during the high-speed switching display of the search screen, the screen data displayed at the time when the stop instruction is input, and the screen data A plurality of image data displayed before the display of screen data is reduced and discretely displayed as a list on a two-dimensional plane. The operator uses the screen thus displayed as a list screen, and from this list screen,

This image data group 31 is also sent to the list display unit 7 in FIG. The operator visually searches the screen displayed while the image data group 31 is switching at high speed. When the target image (the fourth screen in the drawing) is found at the detection timing indicated by 32 in the drawing, the instruction unit 1 in FIG. 1 gives a stop instruction. At this time, there is always a delay time t ′ in the operation time when the operator visually recognizes and gives a stop instruction, depending on the display speed of continuous display. Therefore, conventionally, the display unit 9 of FIG. 1 displays a screen that is not intended by the operator (first screen in the drawing), and the operator displays it on the display unit 9 of FIG. It is necessary to repeat the key operation etc. for returning the screen from the first screen to the fourth screen in the figure.

However, in this example, the image data group 3
The data of No. 1 is traced back in time to generate the reduced screen data 33, and the list screen 34 corresponding to the reduced screen data 33 is displayed on the display unit 9 in FIG. On the list screen 34, the first screen after the delay time t ′ and the second to twentieth screens displayed before the first screen are displayed in a spiral form in a reverse direction. Has been done. In this way, since a plurality of image data is displayed in a list on one screen (list screen 34), the operator can select the desired fourth image data when the stop instruction is issued.
The second screen can be easily recognized.

When the operator designates the desired fourth screen from the list screen 34, the corresponding image data is read from the image data group 31 and the normal size screen 35 is displayed. . At this time, the list screen 34
As shown in FIG. 2, the correspondence between the reduced screen in FIG. 1 and the screen for which the original stop instruction to be displayed is the forward direction held by the page management unit 3 and the speed control unit 2 in FIG. By storing the reverse direction and the current display position at the time of stop by the current display page pointer 23 in FIG. 2,
It can be easily associated.

If there is a search instruction from the operator during reproduction (step 401), it is determined whether the search instruction is forward or backward (step 402). If forward, forward is forward, and if backward. In the opposite direction (step 404),
The page number is read from the page number table 21 of FIG. 2 (steps 405 and 406), the current display page pointer 23 of FIG. 2 is recorded (step 407), the image data of the corresponding page is displayed (step 408), and the next. Wait for the search instruction.

If the search instruction is a stop instruction in step 402 (step 403), the page being reproduced is recorded in the current display page pointer 23 in FIG. 2 (step 409), and the search direction immediately before the stop is reversed. It is determined whether it is the direction or the forward direction (step 410). A plurality of page numbers are read from the page number table 21 of FIG. 2 in the forward direction if the forward direction and in the reverse direction if the backward direction (step 4).
11, 412), and the reduced screen is edited from each page number (step 413). Then, the screens are switched and a list screen composed of a plurality of edited reduced screens is displayed (step 414). If one reduced screen in the list screen is designated (step 415), the designated page is recorded in the current display page pointer 23 of FIG. 2 (step 416) and the screen is switched (step 4).
17) The corresponding image data is displayed (step 408) and waits for the next search instruction.

As described above with reference to FIGS. 1 to 5, in the search screen display control system according to the present embodiment, a constant display speed or a constant display speed is set based on the search designation by the operator.
