BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image editing apparatus and an electronic filing apparatus using the same.

[0002]

2. Description of the Related Art In recent years, electronic filing apparatuses have become widespread in order to store image data such as a large amount of documents and graphics. This electronic filing device has a function of reading image data by optical two-dimensional scanning using a scanner or the like, editing the read image data, and sequentially registering the edited image data in a recording unit such as a magneto-optical disk device. . Then, desired image data is searched and read out from various image data registered in the recording means as needed, and the read image data is displayed on a display means such as a CRT or LCD (liquid crystal display). Alternatively, it can be output by an output means such as a laser printer. The electronic filing device is roughly divided into a peripheral device that reads and outputs image data and an image editing device that processes the image data. I will also explain the device.

A conventional electronic filing device will be described below. FIG. 7 is a block diagram of a conventional electronic filing apparatus, and FIG. 8 is a schematic diagram of a file structure of the conventional electronic filing apparatus. In FIGS. 7 and 8, the image reading unit 1 reads color or monochrome image data 2 with a scanner or the like, and sends the read image data 2 to the image editing apparatus 3 side.

However, in the configuration of the conventional electronic filing apparatus as described above, the user has to create the header information 8 added to the image data 2 one by one. Then, when performing a search, it is necessary to store the items of the created header information 8 without fail, and as the number of files 10 increases, the number of items to be stored also increases, forcing a burden on the user. In addition, if multiple people use the electronic filing device, input information created by another person 1
3 had a number of problems that had to be heard from the person who created it in advance.

An object of the present invention is to solve the above problems and provide an image editing apparatus and an electronic filing apparatus which automatically create one of header information based on color information unique to image data.

By inputting necessary data from the input means 7 including a touch panel and a keyboard, the displayed image data 2 is artificially added with the input information 13 in the area of the header information 18 for editing. In the case of full-color image data 2 which has been edited, for example, the intensity of 2 ⁸ = 256 represented by 8 bits for each of the three primary colors of R, G, B of 1 pixel, 256 ^{3 in} total.
= Display of approximately 16.77 million colors (displaying one color out of 16.77 million colors)
Since it is a huge amount of data that can be
The data amount is compressed by the decompression means 5 and registered as a file 19 in the recording means 9 composed of a magneto-optical disk device, a hard disk device or the like. The file 19 registered in the recording means 9 is searched by searching the header information 18 through the searching means 20, and the read file 19 is restored by the image data compressing / decompressing means 5 in the amount of data, and then the laser is used. The output can be performed by the output means 12 configured by a printer or the like.

With respect to this embodiment, the image reading means 1
Whether the image data 2 read in is color or monochrome,
If the normal processing is performed, the file name, the file registrant name, the keyword of the file to be registered, the file creation date, etc. are artificially input as the input information 13 in the area of the header information 18 as in the case of FIG. 8 described in the conventional example. Can be added. However, when the read image data 2 is in color, the color information extracting means 16 extracts the color information 17 unique to the image data 2, and the header information 18 as shown in FIG.
It is possible to automatically add the color information 17 to the area of 1 separately from the input information 13. In this way, the header information 18

The target file 19 can be searched by collating with the color information 17 through 0.

The color information extracting means, which is the core of the present invention, for automatically adding color information to the read image data will be described in detail below.

1 and 2, the image reading means 1
Reads the image data 2 and sends the read image data 2 to the image editing device 14 side. The image editing apparatus 14, which is the center of the electronic filing apparatus, has a control unit 1 as its main part.
5 and the color information extracting means 16, and the color information extracting means 16 including the display color simplifying means 16a, the appearance frequency calculating means 16b, and the appearance rate coding means 16c.
Processes the following three steps in order to extract the color information 17 from the image data 2.

First, FIG. 3 is a diagram showing a process of compressing the intensities of three primary colors of one pixel of the image data of the electronic filing apparatus according to the embodiment of the present invention, and FIG. Image data of filing device 3
Refer to the figure showing the display color after compressing the intensity of the primary colors,
A process in which the display color simplification means 16a binarizes and compresses the intensities of the three primary colors in the color image data to simplify the display color of each pixel into eight colors will be described.

1 and 3, the display color simplifying means 1 is shown.
6a denotes R, G, and B intensities for each pixel of the image data 2 (for example, 256 of 0 to 255 for full color).
A threshold value is set for each of the R, G, and B values, and the threshold value is set to 1 if the intensity is equal to or higher than the threshold value, and 0 if the intensity is less than the threshold value. To do. In other words, each intensity of R, G, and B, which was displayed in 8 bits, is compressed to 1 bit display (2 bit display, 3 bit display, etc. are possible, but simple 1 bit display is preferable for simplification). Therefore, the display color of one pixel is 256 ³ = about 16.77 million colors (one color out of 16.77 million colors) from 2 ³ = 8 colors display (8 (One of the colors is displayed). For example, if the threshold value is set to "128", "R = 202, G = 124, B = 7" displayed in 8 bits is displayed.
Each intensity of “8” is compressed and displayed by 1 bit, and “R =
1, G = 0, B = 0 ”and displayed in“ red ”.

Next, a process in which the appearance frequency calculating means 16b calculates the appearance frequency of each of the simplified eight display colors for each color for all pixels of the image data 2 will be described.

With respect to the eight display colors determined for each pixel described with reference to FIGS. 3 and 4, the appearance frequency calculation means 16b calculates the appearance frequency of each of the eight colors in all pixels of the image data 2. For example, since the total number of pixels is 307200 in the case of displaying 640 dots × 480 dots,
"Black" = 7200, "Blue" = 71200, "Green" = 79
100, "cyan" = 50800, "red" = 2090
0, "magenta" = 28800, "yellow" = 401
The appearance frequency is calculated for each of the eight display colors such as 00, "white" = 9100.

Finally, a process in which the appearance rate coding means 16c obtains the appearance rate of all the pixels of the image data 2 of the calculated appearance frequency for each color and encodes it will be described.

First, the appearance rate coding means 16c obtains a percentage of each of the eight display colors with respect to the total number of pixels based on the appearance frequencies for each of the eight display colors calculated by the appearance frequency calculating means 16b. . For example, in the case of the previous process, since the total number of pixels is 307200, “black” =
2.34 (%), "blue" = 23.18 (%), "green" =
25.75 (%), ..., “White” = 2.96 (%). Next, the appearance rate encoding means 16c sets a series of percentages for each of the eight display colors, {“black” =
2.34, "blue" = 23.18, "green" = 25.75,
..., "white" = 2.96} is encoded and extracted as the color information 17 of the image data 2.

The color information 17 extracted in this way is
As shown in FIG. 2, the input information 13 is added to the area of the header information 18.
Is automatically added separately from. If a word or phrase indicating each of the eight display colors directly (for example, “red”) or indirectly (for example, “sunset”) is made to correspond to each color, and a database representing the colors is constructed in advance in the searching means 20, This database can be used as a keyword for searching the extracted color information 17.

A series of steps for extracting the color information described above will be comprehensively described with reference to a flow chart showing a process for extracting the color information from the image data of the electronic filing apparatus in the embodiment of the present invention shown in FIG. explain.

The image reading means 1 reads image data with a scanner or the like, and sends the read image data 2 to the image editing device 14 side (step 1). Color information extraction means 16
The display color simplification means 16a binarizes all the pixels of the image data 2 read based on the set threshold value and compresses and displays the R, G, and B intensities of the individual pixels. The colors are simplified to 8 colors (step 2). next,
The appearance frequency calculation unit 16b calculates the appearance frequency of each of the eight colors in all the pixels of the image data 2 for the eight display colors determined for each pixel (step 3). Further, the appearance rate coding means 16c obtains the appearance rate in all pixels of the image data 2 of the calculated appearance frequency for each color for each color, and encodes the obtained series of percentages as the color information 17 ( Step 4). Finally, the extracted color information 17 is written in the area of the header information 18 of the image data 2 (step 5).

A method of searching for a target file based on an image of a color received from the image data by using the color information added to the image data will be described below.

For example, it is assumed that N files having the color information 17 added to the area of the header information 18 are stored in the recording means 9 shown in FIG. In order to search for a target file from these N files, the color image of the file to be searched is recalled. If the file to be searched is a sunset landscape, the corresponding display color is "red", and if "red" is entered from the input means 7, the search means 20 is stored in the recording means 9. The areas of the header information 18 of N files are sequentially searched. Then, all the "red" items of the color information 17 in the area of the header information 18 are investigated, and the corresponding files are displayed on the display means 6 in the descending order of the percentage of the input display color "red". Alternatively, if a database representing colors is built in the search means 20 in advance, even if "sunset" is input, the word "red" is associated with the word "red" and the keyword "red" is input. The same processing is performed as described above, and the corresponding files are displayed on the display means 6 in descending order of the percentage of the display color “red”. However, if there are multiple files with the same percentage of the display color "red", it is judged based on the time when the files were created, and the files are displayed in chronological order. The target file can be searched from among the files displayed in this way.

A series of flow for searching the file described above will be described with reference to the flow chart of FIG. 6 showing the file searching method using the color information of the image data of the electronic filing apparatus in the embodiment of the present invention. To do.

In order to search for the target file, the color image of the file to be searched for is recalled, and the word "red" or the like which directly indicates the corresponding display color or the word "sunset" or the like which indicates indirectly. Input as a keyword (step 6). The display color corresponding to the input keyword is investigated with respect to the color information 17 of all the files (step 7), and there are a plurality of files having the same display color percentage in the descending order of the specified display color percentage. If so, the files are rearranged in the order of creation and displayed on the display means 6 (step 8).

In this way, the target file can be searched by collating it with the color information 17 based on the image of the color recalled from the file to be searched.

In the above description, only the case of the display color "red" was touched, but other display colors "black", "blue",
"Green", "Cyan", "Magenta", "Yellow",
The same applies to "white".
