A color image generation unit (not shown) for generating the scanned electronic document as a color image file;

A black and white image generation unit (not shown) for generating the generated color image file as a black and white image or a gray image file;

A black and white image insertion unit (not shown) for inserting the generated black and white image or gray image file into a tag region of the generated color image file;

A file storage unit (not shown) for storing the black and white image or the gray image inserted in the tag region processed by the black and white image insertion unit as a single file; It provides a method of the present invention by including an inquiry image output unit (not shown) for acquiring and outputting a black and white image or a gray image of a tag region instead of the color image of the data region in the stored color image file. .

The steps of the present invention will be described in detail below.

The electronic document conversion step (S110) is to scan the paper document by the scanner device, and generates the scanned electronic document as a color image file by the color image generating unit (S120).

The generated color image file is generated as a black and white image or a gray image file by the black and white image generator (S130).

That is, referring to FIG. 3, the black and white image generation unit includes a color discrimination module, a hi-low calculation module, a change color rate calculation module, and a black and white conversion module, and the red and blue colors in the color image file by the color discrimination module. Check to generate black and the remaining colors to white, calculate the high and low values of the color to be changed by the high low calculation module, and obtain the rate value of the color to be changed by the change color rate calculation module. The black-and-white conversion module converts the black / white according to the rate value.

That is, the color discrimination module generates black by checking red and blue colors in the color image file and generates the remaining colors as white (S131).

As a preferred example, the following int ConvertBWImage (ImageTag * img, unsigned char ** bwimage, int rgbPriority) is used.

int ConvertBWImage (ImageTag * img, unsigned char ** bwimage, int rgbPriority)

{

int x, y, c;

int l = 255, h = 0;

int avg = 0, cnt = 0;

double sum = 0;

int bCount = 0;

Next, the high low calculation module calculates high and low values of the color to be changed (S132), and the algorithm is as follows.

for (y = 0; y <img-> ysize; y ++)

{

for (x = 0; x <img-> xsize; x ++)

{

c = (int) (img-> image [y] [x * 3 + 0] * 0.2) + img-> image [y] [x * 3 + 1] + int (img-> image [y] [x * 3 + 2]);

l = min (c, l);

h = max (c, h);

}

}

Next, the change color rate calculation module obtains a rate value of the color to be changed (S133), and the algorithm is as follows.

for (y = 0; y <img-> ysize; y ++)

{

for (x = 0; x <img-> xsize; x ++)

{

c = int (img-> image [y] [x * 3 + 0]) + img-> image [y] [x * 3 + 1] + int (img-> image [y] [x * 3 + 2 ]);

if (c <l)

c = 0;

else if (c> h)

c = 255;

else

{

if (h-l == 0)

{

c = ((c-l) * 255);

} else

{

c = ((c-l) * 255) / (h-l);

}

}

bwimage [y] [x] = c;

sum + = c;

cnt ++;

}

}

avg = int (sum / cnt);

Then, the black and white conversion module is converted to black / white according to the rate value (S134), the algorithm is as follows.

if (avg == 0)

{

avg = 255;

}

for (y = 0; y <img-> ysize; y ++)

{

for (x = 0; x <img-> xsize; x ++)

{

c = bwimage [y] [x];

if (c <avg)

bwimage [y] [x] = 1;

else

bwimage [y] [x] = 0;

}

}

return 1;

}

The generated black and white image or gray image file is inserted into the tag region of the generated color image file by the black and white image inserting unit (S140).

That is, the function of inserting the generated black and white image or gray image file into the tag area by the black and white image inserting unit is int Save_TIFF (char * fileName, BYTE * bwimage, int bufSize) and the algorithm is as follows.

int Save_TIFF (char * fileName, BYTE * bwimage, int bufSize)

{

    TIFF * tif;

    tif = TIFFOpen (fileName, "a");

    if (bufSize> 0)

    {

BYTE bsize = (BYTE) bufSize;

TIFFSetField (tif, TIFFTAG_BW_IMAGE, bsize, bwimage);

    }

    TIFFClose (tif);

    return (1);

}

The black and white image or the gray image file and the color image file inserted in the tag region processed through the black and white image insertion step are stored as a file by the file storage processor (not shown) (S150).

When the specific color image file stored in the file storage unit is inquired, the black and white image or the gray image of the tag region is displayed instead of the color image of the data region in the stored color image file. Acquired by the negative and output (S160).

Through the above steps, the black and white image or the gray image file inserted into the tag region of the color image file is downloaded and shown, thereby minimizing the download or loading speed, thereby providing an effect of speeding up the inquiry and processing speed.

In addition, when metadata is input or modified in the color image file stored in the file storage unit, the black and white image or the gray image of the tag region is acquired and modified by the metadata correction unit.

In addition, when the metadata of the color image file stored in the file storage unit is extracted, the metadata extracting unit extracts the black image or the gray image of the tag region instead of the color image of the data region.

General metadata extraction is extracted using neural network algorithm, and this extraction technique is already well known to those skilled in the art, so a detailed description thereof will be omitted.

Meanwhile, as shown in FIG. 2, the color image file of the present invention includes a tag region and a data region, and a black and white image or a gray image file exists in the tag region, and an original color image file is present in the data region. It will exist.

In conclusion, by extracting, inputting, modifying, or inquiring the metadata of the black and white image or the gray image inserted in the tag area, the search and processing speed is minimized by minimizing the download or loading speed than outputting and checking the original color image file. Can be processed quickly.

The image format referred to in the present invention is not limited to any one format such as general TIFF, JPEG, JPEG2000, BMP, and the like.

When creating, compressing, or merging color images (jpeg, jpeg2000, Tiff, etc.) through the above configuration and operation, insert the same black and white image or gray image file into the tag area of the color image file and save them. When the same black and white or gray image is saved in two color image files, and the black and white image or gray image is used for data extraction, input, inquiry, etc., the black and white image or gray image file inserted in the tag area of the color image file is downloaded. By minimizing the download or loading speed, it provides the effect of speeding up the inquiry and processing speed.
