 Next, the operation of the above embodiment will be described.

Here, for example, a case where an image of a business card 19 as shown in FIG. 10 is read and registered, and subsequently searched and output will be described.

FIG. 5 is a flowchart showing the overall operation of the control unit 22. Initially, as shown in step A01, the operation position of the mode changeover switch 14 is "registered".
It is determined which mode setting position of “search” is set.

If the position is the "registration" mode, the process proceeds to step A02, where image data is actually read.
As shown in FIG. 2, the reading unit 17 is brought into contact with the upper surface of a business card 19 to be read, and the scanning is performed on the business card 19 while the reading switch 18 is kept pressed. Are read line by line by the line sensor 28, and are sequentially sent to the control unit 22 via the read control circuit 26. The control unit 22 temporarily stores the sequentially transmitted line-by-line image data in the display register 25a of the RAM 25, and simultaneously sends this to the display control unit 27 as display data,
It is displayed on the display unit 29. After storing all the image data of one business card 19 in the display register 25a, the control unit 22 proceeds to step A.
As indicated by 03, input of index data by the character / numerical key 16 of the key input section 21 is awaited. When the index data is input, the index data is also temporarily stored in a predetermined position of the display register 25a, that is, in a storage area different from the storage area of the image data, and is displayed. Next, it waits for a registration confirmation instruction by operating the execution key 15 in step A04. When the execution key 15 is operated, the process proceeds to step A05, where the effective image area excluding the blank area in the image data stored in the display register 25a, that is, the coordinates of the effective image block portion are detected. And store it in the image data storage area 25b.

FIG. 6 shows a flowchart of the process of detecting and storing the block coordinates. First, as shown in step B01, a row having image data is detected from the bit map of the image data stored in the display register 25a. That is, in the image data stored in the display register 25a, the blank bit is stored as "0" and the black pixel (printed) is stored as "1".

Thus, the horizontal coordinates of the bit map of the display register 25a are represented by x ₀ , x ₁ , x ₂ , x ₃ ,..., And the vertical coordinates y ₀ , y ₁ , y ₂ ,
When y ₃ ,..., the horizontal direction having the same y coordinate is defined as a row, and the vertical direction having the same x coordinate is defined as a column, and it is determined whether each row has at least one pixel data “1”. The determination means is as shown in FIG.

That is, FIG. 7 shows the contents of the process for detecting the presence of data. At the beginning of the process, the control unit 22 initializes the Ya register and Yb of the work area 25d of the RAM 25 in step C01.
The register, Xa register, Xb register, Yc register, Xc register and F flag register are all cleared to “0”. Next, in step C02, the content of the Xc register serving as the search register in the x coordinate direction is updated and set to "+1" to "1", and in the following step C03, the content of the Xc register on the bit map of the display register 25a is indicated. coordinate x ₁ is determined whether the last column.

If it is determined that it is not the last column, the process proceeds to step C09, where the contents of the Yc register, which is a search register in the y-coordinate direction, are “0”, and the coordinates on the bit map of the display register 25a indicated by the contents of the Xc register It is determined whether or not (x ₁ , y ₀ ) has image data, that is, whether or not there is black pixel data “1”. If not, repeat
Returning to C02, the contents of the Xc register are updated and set to "+1", and then the processing of steps C03 and C09 is repeated.

Display contents of Xc register without data
The value indicates the last column on the bit map of 25a, which is determined in step C03, and proceeds to step C04.

In step C04, it is determined whether or not the F flag “1” indicating the presence of data is set in the F flag register.
If it is determined that the value is not set and is "0", the process proceeds to step C07, where the content of the Yc register is updated and set to "+1". In the following step C08, the content of the Xc register is cleared to "0", and the process returns to step C02.

In this way, the value of the Yc register is updated, and the process from step C02 is repeated again with the next line specified.

FIG. 11 shows the block coordinates of the portion of the business card 19 shown in FIG. 10 where the image data is present. In the same figure, when the size of the business card 19 is 55 mm × 90 mm in width and the resolution by the line sensor 28 is 16 dots / mm, the bitmap of the entire business card image data stored in the display register 25a is 880 × 1440 dots. Become. Therefore, the value indicating the last possible row of the Yc register for this business card image data is “879”, and the value indicating the last possible column of the Xc register is “1339”.

In the case of this business card image data, the content of the Yc register is "12
8), the first row with data is detected,
The process proceeds from Step C09 to Step C10.

In Step C10, it is determined whether or not the F flag register is "0". If it is determined that the value is "0", the process proceeds to step C11, where the content of the Yc register is "128".
To the Ya register (Yal register). Thereafter, in step C12, an F flag “1” indicating that data is present is set in the F flag register again, and in step C07, Y flag is set.
After the content of the c register is updated and set to "+1" to "129", the content of the Xc register is cleared to "0" in the following step C08, and the process proceeds to step C09. And step C09
If it is determined that the content of the Yc register is not the value “1339” indicating the last line, the process returns to step C02.

Thereafter, until the Yc register is sequentially updated and set to “240”, when it is determined in step C09 that there is data through steps C02 and C03, the F flag register is set to “0” in step C10. Is determined to be "1", and the process of returning to step C02 through steps C07 to C09 is repeated.

The Yc register becomes 241 and the processing of steps C02, C03, and C09 is repeated while sequentially setting the contents of the Xc register,
When the content of the Xc register reaches the value “1339” indicating the last column without data, this is determined in step C03, and the process proceeds to step C04. If it is determined in step C04 that the F flag “1” indicating the presence of data is set in the F flag register, the process proceeds to step C05, where the value obtained by subtracting “−1” from the contents of the Yc register, that is, the data is continuous. The value “240” indicating the last row that has been set is input to the Yb register (Yb1 register). After that, in step C06, the value “0” indicating that there is no data is set again in the F flag register. In step C07, the content of the Yc register is updated and set to “+1” to “242”. Is cleared to "0", and the process proceeds to step C09.
If it is determined in step C09 that the content of the Yc register is not the value “1339” indicating the last line, the process returns to step C02.

Thereafter, when data is continuously present in the same manner as described above, the values “320”, “400”, and “48” indicating the first and last rows are displayed.
0 ”and“ 640 ”,... Are sequentially stored in the Ya register (Ya2 register,
) And Yb registers (Yb2 register, Yb3 register, ...) are set as input.

Then, when the content of the Yc register becomes "879", it is determined in step C09 that this is a value indicating the last row, and the process of detecting a row with data shown in FIG. 7 is completed.

After the detection of the row with data is completed, the detection of the column with data in the row with data is performed as shown in step B02 in FIG.

FIG. 8 shows the contents of this data sequence detection process. At the beginning of the process, the control unit 2 initializes at step D01.
2 clears the Yc register, Xc register and F flag register of the work area 25d of the RAM 25 to "0".
Next, in step D02, the value "128" once held in the Ya register (Ya1 register) is set to "-1" and input to the Yc register as "127". Then, in step D03, the value of this Yc register is set to "+1". Then, the value is set again to the value “128” indicating the first row having data. Then, after it is determined that the value of the register DYc does not exceed the value "240" indicating the last row having data held in the Yb register (Yb1 register), the search register in the y coordinate direction is set in step D11. It is determined whether or not the image data exists at the coordinates (x ₀ , y ₁₂₈ ) on the bit map of the display register 25a indicated by the content “128” of the Yc register and the content “0” of the Xc register. If it is determined that there is not, return to step D03 again, and
Step D after updating the contents of the c register to "+1"
Repeat steps 04 and D11.

If the content of the Yc register exceeds the value of the Yb register without any data, this is determined in step D04, and the process proceeds to step D05.

In step D05, it is determined whether or not the F flag “1” indicating the presence of data is set in the F flag register.
If it is determined that it has not been set and is "0", the process proceeds to step D08 to update and set the content of the Xc register to "+1". In step D09, the value "128" once held in the Ya register (Ya1 register) is set to "-1" and input to the Yc register as "127" in the same manner as in step D02, and then the content of the Xc register is set in step D10. Is determined not to be the value “1339” indicating the last column, and then step D03 is performed again.
Then, the value of this Yc register is set to "+1" and set again to the value "128" indicating the first row having data.

In this way, the value of the Xc register is updated, and the process from step D03 is repeated again with the next column specified.

In the case of this business card image data, the content of the Xc register is "8
When it reaches 0, the first row with data is detected,
The process proceeds from Step D11 to Step D12.

In step D12, it is determined whether or not the F flag register is "0". If it is determined to be "0", the process proceeds to step D13, where the content of the Xc register is "80".
To the Xa register (Xa1 register). Then, in step D14, an F flag “1” indicating that data is present is set again in the F flag register.
After updating the contents of the c register to "+1" and setting it to "81", in the following step D09, the Ya register (Ya1 register) is temporarily
The value "128" held in the
After input setting in the register, it is determined in step D10 that the content of the Xc register is not the value “1339” indicating the last column, and the value of the Yc register is again set to “+” in step D03.
"1" and set again to the value "128" indicating the first row with data.

Thereafter, until the Xc register is sequentially updated and set to "144", when it is determined that there is data in step D11 through steps D03 and D04, the F flag register is set to "0" in step D12. Is determined to be "1", and the process of returning to step D03 via steps D08 to D10 is repeated.

The Yc register becomes “145” and the processing of steps D02, D03, D09 is repeated while sequentially setting the contents of the Yc register,
If it is determined that the value exceeds the value "240" indicating the last row having data held in the Xb register (Yb1 register) without data, this is determined in step D04, and the process proceeds to step D05. If it is determined in step D05 that the F flag “1” indicating the presence of data is set in the F flag register, the process proceeds to step D06, where the value obtained by subtracting “−1” from the contents of the Xc register, that is, the data is continuous. Xb register (Xb1 register) that indicates the value of the last column that was

After setting the input as 7 in the Yc register, the process proceeds to step D10. When it is determined in step D10 that the content of the Xc register is not the value “1339” indicating the last column, the process returns to step D03.

Thereafter, when data is continuously present in the same manner as described above, values “208”, “272”, and “32” indicating the first and last columns are displayed.
"0" and "384" are sequentially set in the Xa register (Xa1 register) and the Xb register (Xb1 register) and input and set.

Then, when the content of the Xc register becomes “1339”, it is determined in step D09 that this is a value indicating the last column, and the ninth character string “ABC” on the first line in FIG. The processing of the Ya1 register, the Yb1 register, the Xa1 register, and the Xb1 register in the figure has been completed, and thereafter, as shown in step D15, the same applies to the second and subsequent data rows in FIG. Is repeatedly executed. Then, when the detection of the data columns for all the data rows detected in FIG. 7 is completed, the detection processing of the columns with data shown in FIG. 8 ends.

At the time when the detection of the data presence column is completed, the detection of the block coordinates is also completed as shown in FIG. 6, so that the process proceeds to step A06 in FIG. RAM2 only the image data in the area
Stores stored in the image data storage area 25b of 5, sets the address of the storage location in the address storage unit J ₂ of the index area 25c.

By the registration process described above, the image data of one business card is stored in the image data storage area 25b, and the address and coordinate data on the image data storage area 25b are stored in the index area 25c together with the index data.
For example, it is stored at a position indicated by, for example, a page number (P No.) “1”.

Thereafter, each time a business card image is read, the image data is stored in the image data storage area 25b, and the index data, address, and coordinate data are stored in the positions indicated by the page numbers “2”, “3”,. It is memorized.

Next, a description will be given of a process in a case where arbitrary image data is searched from among the many image data. There are two methods for performing a search. One is a method for inputting index data as in the past, and the other is a sequential key (not shown) provided on the character / numerical key 16 described above.
How to operate.

To search for image data, the mode switch 14 is set to the "search" mode. At this point, if the character key of the character / numerical key 16 is operated, it is determined that the search is based on the index data, and the processing of FIG. 5 is executed again by inputting the index data. At the beginning, it is determined in step A01 that the mode is the "search" mode, and in subsequent step A07, it is determined that the input is the index data, and the index data is temporarily stored in the work area 25d of the RAM 25. . After waiting for the execution key 15 to be operated in step A08, each page number “1” of the index area 25c is set.
"2", "3" ... the content of the index data storage unit J ₀ is a search in order that the match from the region attached. Then, it is determined whether or not there is a match in step A09.If there is, the process proceeds to step A10, where the coordinate data of the effective block corresponding to the index data is read from the index area 25c, reads the business card image data from the image data storage area 25d in accordance with the contents of the address memory section J _2, stores the read out image data to the display register 25a so that the original position in accordance with the coordinate data, display output on the display unit 29 so Then, the process ends.

If it is determined in step A09 that there is no image data having the index data that matches the input index data, then in step A12, an error display indicating that there is no matching data is displayed on the display unit 29. , And the process ends.

Further, when the sequential key of the character / numerical key 16 is operated while the mode changeover switch 14 is set to the "search" mode, this is performed through step A01 to step A12.
, And the process proceeds to step A13. In step A13, a block of image data that is considered to indicate “name” is estimated and detected from each of the plurality of blocked business card image data stored in the image data storage area 25b of the RAM 25.

This is based on the coordinate data stored in the index area 25c, and the one satisfying the three conditions of (I) 4 mm ≦ character height ≦ 6 mm (II) 2 ≦ number of characters ≦ 8 (III) character spacing ≧ 3 mm This is performed by estimating that the block indicates the name.A plurality of image data corresponding to the coordinate data corresponding to the condition is read out from the image data storage area 25b as `` name '', and the page is read as shown in the subsequent step A14. The number is displayed together with the number on the display unit 29, and this process ends.

FIG. 12 shows an example of the display state. In a state where a plurality of “names” are displayed together with the page numbers, the page number corresponding to the “name” for which the entire image data is desired to be displayed is represented by characters / numerical values. When a key input is performed using the numeric key of the key 16, the key input is detected in step A15 through step A01 in FIG. 5, and after waiting for operation of the execution key 15 in step A16, the coordinate data of the valid block corresponding to the page number in A17 the index area 25c reads, also reads the business card image data according to the contents of the address memory section J ₂ from the image data storage area 25b, according to the read image data coordinate data The data is stored in the display register 25a so as to be the original position, and the display is output on the display unit 29, and the process is terminated.

As described above, according to the above-described embodiment, all the name card portions of a large number of business card image data are simultaneously displayed, and by selecting a desired name from among them, all the business card image data of that name can be displayed. This makes the search extremely easy.

In the above embodiment, the block of the name is detected based on the conditions of the character height, the number of characters, and the character spacing. However, the detection condition is not limited to the above condition. For example, in a business card in English (Roman characters), the number of characters in the name is further increased, and the character spacing is further reduced.

Also, the embodiment in which the attribute of name is detected has been described.
Other attributes can be detected, for example, a TEL number, a company name, and the like can be detected. For example, in the case of a company name, business cards of the same company are printed at the same position and in the same size when printing the company name. Therefore, for example, a business card image of a certain person is displayed, and only the image data portion of the company name in the image is designated by the cursor, for example, by key operation, and the same as the block of the company name displayed by operating the execution key or the like. Business card image data having a size and the same number of blocks can be searched, so that only business card images of people of the same company can be sequentially displayed without index input.

Further, a technique for outputting desired image data from such a large number of image data is not limited to a business card image,
The present invention is applicable to general documents, and the present invention is not limited to a business card image reading device.

[Effects of the Invention] As described in detail above, according to the invention, image data is read by, for example, an image scanner or the like, and an effective image portion of the read image data is written and stored in storage means together with its position information, Specific attribute data in the stored image data, for example, "Name" for a business card image
The data is detected and displayed for a plurality of data together with the information indicating the storage position, and when any of the plurality of displayed information is selected and the information indicating the storage position is input, the corresponding business card image data Is called for display output or print output, it is possible to provide an image display control device capable of outputting arbitrary image data without inputting and setting index data.
