BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image and image output method and apparatus.

[0002]

2. Description of the Related Art Conventionally, in an electronic filing system, when image reading instruction data is sent from an input means such as a keyboard to a CPU, the CPU reads an image as image data by an image reader through an image reader control device. The CPU stores the read image data in the external storage device via the external storage control device. Thus, the conventional electronic filing system
The image was stored as it was as image data.

In this storage, the image data was directly decomposed into pixels and stored.

[0004]

The electronic filing system according to the prior art reads an image as it is as image data. Therefore, in handwritten images such as handwritten characters filled in the questionnaire sheet, the characters are handwritten, so that the sizes of the characters are not uniform, and the characters are arranged differently from each other. For this reason, the image read from the storage device and output to the output device is difficult to see because it is difficult to see and read, which is a drawback.

An object of the present invention is to enable a graphic image input at an arbitrary input position to be arranged and output at a predetermined arrangement position.

[0006]

Means and Action of the Invention The means and operation of the present invention detect an arrangement area of a desired image input at an arbitrary input position, and detect an input image image in the area from the detected area. Is extracted, and the input image image is arranged and output at a predetermined predetermined output arrangement position.

Expressed by

In the character recognition of the present embodiment, first, a character is laterally distinguished one by one to classify the characters one by one. Next, the process of obtaining the upper position coordinate and the lower position coordinate of the character portion of the divided one character is performed to obtain the upper and lower positions of each character.

First, a method of dividing characters in the horizontal direction will be described. The character division in the horizontal direction is the character size recognition device 6.
Via the CPU 16 takes a projection of the image data stored in the internal memory 5 of the CPU 16 on the horizontal axis, and identifies the start and end points of the black portion of the projection. That is, the character size recognition device 6 performs an OR operation on the image data stored in each memory in the order of the memory M _1,1 and the memory M _1,2 with respect to the memory corresponding to the pixel on the left first column in a column unit. , And stores the result in the x-axis mapping memory D ₁ as an x-axis mapping. Similarly, for each pixel in the second column from the left, the memory M _2,1 corresponding to each pixel, the memory M
_2,2 , ..., OR the respective image data in the memory M _2,12
The calculation is performed to obtain the x-axis mapping, and the result is the x-axis mapping memory D ₂

Likewise the result of the third column of the x-axis mapping stored in the memory D _3, sequentially performs OR operation of the image data corresponding to each pixel in units of columns to the m-th column, the data of x-axis mapping each column below Are stored in the x-axis mapping memory D _m ( _m is a subscript representing 1 to _m columns) corresponding to each column.

Next, the character size recognition device 6 includes a CPU 16
X-axis mapping data stored in the internal memory 5 via x
Read from each memory from the axis mapping memories D ₁ to D _m ,
An exclusive OR operation is performed on the data corresponding to the first column and the data corresponding to the second column. Then, an exclusive OR operation is performed on the data corresponding to the second column and the data corresponding to the third column. As described above, the exclusive OR operation is sequentially repeated from the first column before and after the data in the memory D _m corresponding to each column. The x-coordinate data of the memory D _m when the result of the exclusive OR operation first changes from 0 to 1 is stored in the internal memory 5 as the character start point coordinate data x ₁ . Further, the character size recognition device 6 stores the result of the x-axis mapping in the memory D _m.
The exclusive OR operation is repeated between the memories before and after each other,
Next, the memory D _m-1 when the exclusive-OR operation result changes from 0 to 1 (that is, the x-coordinate value data of the memory before and after the exclusive-OR operation) is used as the character end point coordinate data x. ₂ is stored in the internal memory 5. In this way, the exclusive OR operation before and after the memory D _m storing the result of the x-axis mapping is repeated, and the x coordinate value data of the change point of the obtained data (exclusive OR operation at the change point of the odd number) The x-coordinate value data of the latter memory is taken, and the x-coordinate value data of the former memory is taken at the even-numbered change point). The x-coordinate value data x ₁ of the first time is the character start point of the first character. In the x-coordinate value data indicating the second character, the _second x-coordinate value data x ₂ is the x-coordinate value data indicating the character end point of the first character. The data x _{1 to} x _K are stored in the memory 5 via the CPU 16. The character start point x ₁ and the character end point x ₂ shown in FIG. 3 are the coordinate values of the character start point memory D ₄ and the character end point memory D ₁₀ of the mapping of the character 2 onto the x-axis.

Next, the operation of the character size recognition device 6 for determining the height of a character will be described. The character size recognition device 6 performs an OR operation of each memory on a line-by-line basis with respect to the image data corresponding to the x-axis character surrounded by the character start point data and the character end point data stored in the memory 5, The result is stored in the y-axis mapping data memory R _n as y-axis mapping data.

Next, the character size recognizing device 6 stores the y-axis mapping data memory R _n into the y-axis mapping memory R ₁ corresponding to the bottom of the pixel and the y-axis mapping memory R _{2 in the} second row from the bottom. Perform an exclusive OR operation. Similarly, an exclusive OR operation is performed on the y-axis mapping memory R ₂ corresponding to the second row from the bottom and the y-axis mapping memory R ₃ corresponding to the third row from the bottom. This exclusive OR
The operations are sequentially repeated from the bottom row, and the y of the y-axis mapping memory R _n when the exclusive OR operation result first becomes 0 to 1
The coordinate value data is stored in the internal memory 5 as the character position coordinate value L _l (l is a subscript indicating the number of characters when counted from the left side of the image). When the character size recognition device finds L _l ,
The exclusive OR operation from the lower row to the y-axis mapping data memory R _n is stopped, and the y-axis mapping data memory R _n at the top row is stopped.
An exclusive OR operation is performed between _n and the y-axis mapping data memory R _{n-1 in the} second row from the top. Further, the character size recognition device 6
An exclusive OR operation is performed on the y-axis mapping data memory R _n-1 corresponding to the second row from the top and the y-axis mapping data memory R _n-2 corresponding to the third row from the top. Thus, the y-coordinate value data of the latter y-axis mapping data memory R _n when the result first changes from 0 to 1 is stored in the internal memory 5 as the character position coordinate U _l .

As described above, the character size recognition device 6 causes the character start point data and the character end point data x _{1 to} x _K corresponding to the character portion of the image and the character lower position coordinate value L _l indicating the lower end and the upper end of the character. And the character position coordinate value U _l are stored in the internal memory 5 via the CPU 16.

Next, the operation of the image data enlarging / reducing device 7 will be described. Image data enlargement / reduction device 7
First, it outputs the image data in which the character sizes of the image data are aligned to the external storage controller 8.

The operation of enlarging and reducing the image data character portion of the image data enlarging / reducing device 7 will be described in detail below. When the character size recognition device 6 finishes the process of obtaining each data of character size for the image data corresponding to one image, the CPU 16 issues an instruction to the process of the image data enlargement / reduction device 7 to the image data enlargement / reduction device. Tell 7. The image data enlarging / reducing device 7 is C

Similarly, for the character upper position coordinate value U _l and lower character position coordinate value L _l corresponding to each character part of the image data,
The image data enlargement / reduction device 7 repeats the difference calculation for each character. When the calculation for all the characters of one image data is completed, the image data enlargement / reduction device 7
Calculates the mean value H _M of data in the internal memory H ₁ to H _l for storing character height, is stored in the internal memory 5 as an average value H _M character height. Next, the image data enlarging / reducing device 7 reads out the reference value data H ₀ of the character size stored in the internal memory 5 in advance by an input means such as a keyboard (not shown) through the CPU 16 and calculates and outputs it first. The ratio of the average character height data H _M to the calculated character height is calculated, and the result is stored in the internal memory 5 as the enlargement ratio data B ₀ . Further, the image data enlargement / reduction device 7 sets the value of the enlargement ratio data B ₀ in advance and stores the twelve kinds of enlargement ratios B1 (0.33 times) stored in the internal memory 5 (the numerical value in the parentheses is the actual enlargement ratio). , The magnification ratio B2 (0.41 times),

When the enlargement ratio B is determined, the image data enlargement / reduction device 7 obtains each enlargement ratio by combining the above-described six sets of enlargement / reduction techniques programmed in the internal memory 5 via the CPU. That is, the reduction method 2/3 and the reduction method 1/2 are combined to obtain the enlargement ratio B1 (0.33 times), and the reduction method 5/6 and the reduction method 1/2 are combined to obtain the enlargement ratio B2 (0.41 times). 6/5 and enlargement method 6/5 are combined to obtain enlargement ratio B8 (1.44 times) and enlargement method 3/2
And enlargement method 6/5 are combined, and enlargement ratio B9 (1.8 times)

The magnification ratio B12 (3 times) is obtained by combining the same with / 2. Image data enlargement / reduction device 7 has enlargement ratio B3 (0.5 times)
The reduction method is 1/2, the reduction method is 2/3 when the enlargement ratio is B4 (0.66 times), the reduction method is 5/6 when the enlargement ratio is B5 (0.83 times), and the enlargement ratio is B7 (1.2 times). In case of), enlargement method 6 /
5 and the enlargement method 2/1 is used independently when the enlargement ratio is B10 (2.0 times). When the enlargement ratio is B6 (1 ×), the enlargement / reduction method is not used and the image data is output as it is to the external storage control device 8.

The image data enlarging / reducing device 7, when enlarging / reducing character data of image data by executing each enlarging method or reducing method, performs the following processing on the image data to enlarge the image data. , Or reduce.
The image data enlargement / reduction device 7 uses the enlargement method (n + 1 /
When n) is selected, n pieces of image data of the image data stored in the internal memory 5 are cut out and n + 1 pieces of image data are output to the internal memory 5. At this time, the type of image data to be increased takes a larger value out of two values of 1 indicating a black point or 0 indicating a white point in the n image data. When the value 1 indicating a black dot and the value 0 indicating a white dot are the same number, 1 indicating a black dot is output to the internal memory 5. The increasing position is output to the next coordinate where the increasing types of points are continuous.

If there is a point of the same kind as the kind of increase in two or more places, it is output to the coordinates after the same point as the kind of increase that was cut out last. The above enlarging method is performed from the lower stage to the uppermost stage in the x-axis direction of the image data, and then from the left column to the rightmost column in the y-axis direction to obtain the image data at the enlargement ratio (n + 1 / n) times. obtain. if,

Of the image data of lesser number) or white points (points of data 0) are deleted. If the number of black dots and white dots is the same, the white dots are deleted. The position to delete is the image data of the coordinates where the image data to delete is not continuous,
When the image data to be deleted is discontinuous and the same number exists in two or more places, the image data cut out later is deleted. The above reduction method is performed in the x-axis direction of the image data in order from the bottom to the top, and output to the internal memory 5. Further, the same processing as in the above-mentioned x-axis direction is performed in the y-axis direction on the image data for which the reduction processing in the x-axis direction has been completed, from the left column to the rightmost column, and the enlargement ratio (n-1 / n) times is applied.
