Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device that sequentially displays a plurality of images, and in particular, the present invention relates to a device that sequentially displays a plurality of images. The present invention relates to a suitable image display device for searching.

[Conventional technology]

In the conventional technology, as described in Japanese Patent Application Laid-Open No. 58-84365, it was only possible to check the number of images classified into one by overlapping display in which the display positions of the images were changed little by little. No consideration was given to using overlapping display to search for multiple images and displaying pages by turning them in both forward and reverse directions. When searching for a desired image by checking a large number of images one by one, there are two ways to search: forward page flipping, which displays images in the order they are searched, and reverse page flipping, which displays images in the reverse order. It is necessary to display sequential information in a way that is easy for humans to understand.

Furthermore, when searching for images, it is necessary to display each image one by one from a large-capacity storage device such as an optical disk on a display device. It takes some time (1 to 2 seconds) to read a desired image from a large-capacity storage device such as an optical disk. Therefore, in order to display images instantly (0.1 seconds) in response to human instructions, like turning the pages of a book, it is necessary to temporarily store images from an optical disk in a high-speed buffer memory such as a semiconductor storage device. .

In addition, when searching for images, it is also important to know how many images from the optical disc are currently being input into a high-speed buffer memory such as a semiconductor storage device that can be displayed immediately.

In other words, psychological discomfort can be reduced by informing the operator of whether the image they are about to view can be viewed immediately or whether it will take some time. As described above, in the conventional technology, sufficient consideration has not been given to searching multiple images.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not take into consideration the display method when searching for a plurality of images, and there is a problem when searching for a document consisting of a plurality of images selected under certain conditions.

The first object of the present invention is that when searching for a desired image from among a plurality of images, by knowing where in the document the image is located, the image that comes to mind instantly can be searched. The purpose is to find it accurately.

The second purpose is to present a display method that allows users to quickly determine whether a page is being turned in the forward direction or in the reverse direction just by looking at the displayed screen.

The third purpose is to present a display method that can determine how many images have been stored in a high-speed buffer memory such as a semiconductor that can immediately display images from a large-capacity storage device such as an optical disk. In addition, even while you are visually checking the images on the high-speed memory while searching, the images are transferred from the mass storage device to the high-speed buffer memory in parallel with the search operation.
The purpose is to improve search efficiency.

[Means for solving problems]

The above object is achieved by changing the forward and reverse display methods when sequentially displaying a plurality of images.

In addition, you can check how many images are ready to be displayed immediately by checking only a portion of the image that has been stored in the high-speed buffer memory that can be displayed immediately from the mass storage device. This can be achieved by displaying them sequentially.

[Effect]

The displayed plural images are displayed three-dimensionally in both forward and reverse directions. As a result, the searched image will be displayed in the same way as the image in the book, so the position of the currently displayed image.

There is no need to misunderstand the direction of the display or the content.

Further, the state of an image that can be immediately viewed can be determined from the display screen by sequentially displaying parts of the image.

By performing a search for each image one by one and transferring them to a high-speed buffer memory where they can be viewed immediately, the waiting time until the first image searched is displayed is reduced. , the psychological burden on the operator can be reduced.

Hereinafter, the principle of the basic method for realizing the above functions will be explained using diagrams.

FIG. 1 shows one display screen of the display method of the present invention. A display screen 101 includes a starting point marker 102 indicating the position of the first image retrieved, an image 103 currently being displayed, and a portion showing a part of the image stored in a high-speed buffer memory that can be immediately displayed from a mass storage device. It is composed of images 104.

The display screen 101 in FIG. 1 shows a state in which the searched images have been turned over several pages in the forward direction from the first image.

The progress of display will be specifically explained using FIG. 2.

When the search starts, the start point marker 112 is displayed. Immediately after the #1 image retrieved from the 0th order mass storage device is stored in the high speed buffer memory and can be displayed one time, the image 113 is displayed. Display. The display position of this first image 113 is a position in contact with the starting point marker 112.

The exact display position of the first image will be described. One point of the starting point marker 112 is set as a starting point marker reference point.

For example, in the example of Fig. 2, the origin of the image 113 is set to the point 1 at the lower left of the image, with the point 112a as the starting point marker reference point.
13a.

The first image 113 displays the starting point marker reference point at a position that coincides with the origin of the image.

When the second image is stored in the high-speed buffer memory from the mass storage device, the origin of the second image is set by ΔX and Δy both vertically and horizontally from the starting marker reference point 102a. (However, ΔX, Δy>0) are displayed at a position apart from each other. However, instead of displaying the entire screen of the second image, a partial image 114 of the part that does not overlap with the first image is displayed.
Display only.

Each time an image is stored in the high-speed buffer memory from the mass storage device, the origin of the image is moved away by ΔX and Δy, and only the partial image 114' is displayed.

The operation of forward page turning will be explained with reference to FIG.

When performing forward page turning, after displaying the entire area 123 of the first image in the same color as the background (usually white),
A second image 123' is displayed. At this time, instead of displaying the entire second image 123', only the remaining portion of the image 124 that was displayed when the image was stored from the mass storage device to the high speed memory may be displayed.

Also, instead of displaying (filling) the entire area of the first image with the background color, you can display (fill) only the area of the first image that does not overlap with the area of the second image with the background color. good.

The operation of reverse page turning will be explained using the fourth WI. Assume that the third image 133 is currently being displayed. When performing a reverse page turn, simply select the second image 1.
33' may be displayed in the area where the second image was displayed in the past.

FIG. 5 shows Δx=0. This is the display screen when Δy>O, and FIG. 6 shows the display screen when Δy>0. This is a display screen when Δy=o.

Also, set a starting point marker at the top right of the display screen.

Δxku0. It is also possible to set Δy<O, as shown in FIG.

Similar to FIG. 3, Δx=0. Δy < O or Δx 0
, Δy=Q.

A modification of the basic principle will be explained using FIG.

In a typical document image, the periphery of the image is often white. Therefore, if the outline of the document image is displayed with a black frame, for example, the display will be easier to understand. At this time, instead of displaying the partial image 104 that does not overlap with the first image, only the non-overlapping portion of the black frame may be displayed.

Also, in forward page turning, instead of filling only the area of the first image that does not overlap with the area of the second image with the background color, fill in the area of the first black frame that does not overlap with the area of the second image. It is also possible to fill only a portion with the background color.

The image 103 to be displayed may be not only an image such as a photo 9 figure, but also an image representing a document created by a word processor or the like and expressed by character codes.
