Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image storage device that reads and stores image data, and displays or prints the image data as necessary.

2. Description of the Related Art Conventionally, image data such as a document is read using an image scanner, index data is added to the read image data, and a plurality of pieces are stored in a storage unit such as a memory or a magnetic disk. An image storage device that retrieves and reads out arbitrary image data by designating index data in accordance with, and displays or outputs the image data is proposed. In this type of image storage device, a plurality of image data can be stored.

[Problems to be Solved by the Invention] However, the above image data is stored as it is including a blank area regardless of the amount of data. For example, if the read data is blank, , The bit of the value “0” is stored, and the bit of the value “1” is stored when the effective image, that is, the black printing is performed. When the data is called, the image data consisting of "0" and "1" stored in the storage means is called and displayed or printed out as it is.

If the image data is stored as it is as described above, the amount of image data required for storage increases, and the storage capacity of the storage unit is increased, so that only a limited number of data can be stored.

Therefore, it is conceivable to designate only an effective image portion in one image data as an area and store only the image data in the designated area. However, when there are many effective image portions in the image data, When the region has a complicated shape, the operation of designating the region is troublesome and is not realistic.

Further, as described above, when image data is stored and displayed in units of one image as it is, even when it is desired to check only specific items in the image data, the image data must be sequentially called and displayed one by one. The operation becomes troublesome. Further, when the position of the specific item in the image data is different for each image data, it is difficult to confirm the specific item, and it takes time unnecessarily. For example, even if a business card file device that stores image data such as business cards and calls it as needed is considered, a company name, a name,
Since the printing position of each item such as an address and a telephone number differs depending on the business card, it is difficult to confirm.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and makes it possible to effectively use the capacity of a storage unit for storing image data, to store more image data, and to specify image data. It is an object of the present invention to provide an image storage device capable of outputting only image block data corresponding to an item.

Means and Action for Solving the Problems According to the present invention, image data is read by, for example, an image scanner or the like, and valid image data blocks in character units in one read image data and position information thereof are detected. After that, the effective image data and the position information are changed and set by designating the integration including the integration of the character strings extending over a plurality of lines of the effective image data block. Is written and stored in the storage means, and one of a plurality of items prepared in advance corresponding to each effective image data is selected and stored and set. Only the effective image data corresponding to the image data is read out and displayed or printed out. In addition to storing image data, necessary image data can be easily and reliably searched.

It comprises a Yc register, an Xc register, an F flag register, an M register for item search, and the like. Image data temporary storage
An area 25e is temporarily stored when the image data is divided into blocks, and has at least a number of bit memories corresponding to all the bitmaps of the image data of one read business card.

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

Here, a case where the image of the business card 20 as shown in FIG. 12 is read and registered, and subsequently searched and output will be described as an example.

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.
In this case, as shown in FIG. 2, the reading unit 18 is brought into contact with the surface of the business card 20 to be read, and the business card 20 is scanned, for example, in the longitudinal direction while the reading switch 19 is kept pressed. The image data 20 is illuminated by a lamp 29 and read by the line sensor 28 in line units.
The data is sequentially sent to the control unit 22 via 26. The control unit 22 temporarily stores the sequentially transmitted line-by-line image data in the display data storage unit 25a and the image data temporary storage unit 25e of the RAM 25, and sequentially controls the display data stored in the display data storage unit 25a as display data. It is transmitted to the unit 27 and displayed on the display unit 30. Display data storage unit for displaying all image data of one business card 20
When the read switch 19 is released after holding the image data in the image data temporary storage unit 25e and the image data temporary storage unit 25e, the control unit 22 removes the blank area in the image data held in the image data temporary storage unit 25e as shown in step A03. The image area, that is, the coordinates of the effective image block portion is detected and the image data storage
Store in 25b.

The detection and storage of the block coordinates include a data row detection process for detecting a row of image data by a bit map of the image data stored in the display register 25a, a data row detection process in the data row, and the like. This is performed by two processes of storage. 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 lateral coordinate of the bitmap display register _{25a x 0, x 1, x} 2, x 3, ..., in the vertical direction coordinate _{y 0, y 1, y 2} , y 3, ...
When 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, it is determined whether or not each row has at least one pixel data “1”. The judgment is made by the line detection processing, and the processing means is as shown in FIG.

That is, FIG. 6 shows the detailed processing contents of the data presence detection. At the beginning of the processing, the control unit 22 initializes the Ya, Yb, and Xa registers of the work area 25d of the RAM 25 in step B01. , Xb register, Yc register, Xc register and F flag register are all cleared to “0”. Next, in step B02, the content of the Xc register serving as the search register in the x-coordinate direction is updated and set to "+1" to "1". In the subsequent step B03, the bit map of the display register 25a indicated by the content of this Xc register is displayed. 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 B09, where the contents of the Yc register, which is a search register in the y-coordinate direction, "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 it is determined that there is not, repeat step B0
After returning to 2, the contents of the Xc register are updated and set to "+1", and then the processing of steps B03 and B09 is repeated.

Display contents of Xc register without data
When the value indicates the last column on the bit map of 25a, this is determined in step B03, and the process proceeds to step B04.

In step B04, 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 B07 to update and set the contents of the Yc register to "+1". In a succeeding step B08, the content of the Xc register is cleared to "0", and the process returns to the step B02.

In this way, the value of the Yc register is updated, and the processing from step B02 is repeatedly executed again with the next line specified.

FIG. 13 shows the block coordinates of a portion of the business card 20 shown in FIG. 12 where the image data is present. In the same figure, when the size of the business card 20 is 55 mm in length × 90 mm in width and the resolution by the line sensor 28 is 16 dots / mm, the bit map 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 B09 to step B10.

In step B10, 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 B11, where the content of the Yc register is "128".
To the Ya register (Ya1 register). Thereafter, in step B12, an F flag “1” indicating that data is present is set again in the F flag register, and in step B07, 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 subsequent step B08, and the process proceeds to step B09. And in step B09
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 B02.

Thereafter, until the Yc register is sequentially updated and set to "240", when it is determined that there is data in step B09 via steps B02 and B03, the F flag register is set to "0" in step B10. Is determined to be "1", and the process of returning to step B02 via steps B07 to B09 is repeated.

The Yc register becomes 241 and the processing of steps B02, B03, and B09 is repeated while sequentially setting the contents of the Xc register,
When the content of the Xc register becomes the value “1339” indicating the last column without data, this is determined in step B03, and the process proceeds to step B04. If it is determined in step B04 that the F flag “1” indicating the presence of data is set in the F flag register, the process proceeds to step B05, where the value obtained by subtracting “−1” from the content 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). Then, in step B06, the value "0" indicating that there is no data is set again in the F flag register. In step B07, the content of the Yc register is updated and set to "+1" to "242". Is cleared to “0”, and the process proceeds to step B09.
If it is determined in step B09 that the content of the Yc register is not the value “1339” indicating the last line, the process returns to step B02.

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 B09 that this is a value indicating the last row, and the process of detecting a row with data shown in FIG. 6 ends.

After the detection of the row with the data is completed, the detection of the column with the data in the row with the data is performed.

FIG. 7 shows the contents of this data sequence detection process. At the beginning of the process, the control unit 2 initializes at step C01.
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 C02, the value "128" once held in the Ya register (Ya1 register) is set to "-1" and input to the Yc register as "127", and then the value of this Yc register is set to "+1" in step C03. Then, the value is set again to the value “128” indicating the first row having data. Then, after it is determined in step C04 that the value of the Yc register does not exceed the value "240" indicating the last row having data held in the Yb register (Yb1 register), a search in the y coordinate direction is performed in step C11. 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 C03 again, and
Step C after updating the contents of the c register to "+1"
Repeat steps 04 and C11.

If the content of the Yc register exceeds the value of the Yb register without data, this is determined in step C04 and the process proceeds to step C05.

In step C05, 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 C08, where the content of the Xc register is updated and set to "+1". In the following step C09, 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 C02, and then the content of the Xc register is set in step C10. Is determined not to be the value “1339” indicating the last column, and then step C03 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.

Thus, the value of the Xc register is updated, and the process from step C03 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 C11 to Step C12.

At step C12, 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 C13, where the content of the Xc register is "80".
To the Xa register (Xa1 register). Then, in step C14, the F flag “1” indicating that data is present is set again in the F flag register.
After updating the content of the c register to “+1” and setting it to “81”, in the following step C09, the Ya register (Ya1 register) is temporarily
The value "128" held in the
After input setting in the register, it is determined in step C10 that the content of the Xc register is not the value “1339” indicating the last column, and then in step C03, the value of the Yc register is set to “+” again.
"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 through step C03 and D04 that there is data in step C11, then the F flag register is set to "0" in step C12. Is determined to be "1", and the process of returning to step C03 via steps C08 to C10 is repeated.

The Yc register becomes “145”, and the processing of steps C02, C03, and C09 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 C04, and the process proceeds to step C05. If it is determined in step C05 that the F flag “1” indicating that data is present is set in the F flag register, the process proceeds to step C06, where a 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
Input setting. After that, in step C06, a value “0” indicating no data is set again in the F flag register,
In step C08, the content of the Xc register is updated and set to “+1” to “146”, and then in step C09, the Ya register (Ya
1) to “-1” from the value “128” held in
After setting the input as 7 in the Yc register, the process proceeds to step C10. When it is determined in step C10 that the content of the Xc register is not the value “1339” indicating the last column, the process returns to step C03.

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 (Xal register) and the Xb register (Xb1 register) and set.

Then, when the content of the Xc register becomes “1339”, it is determined in step C09 that this is the value indicating the last column, and the ninth character string “ABC” on the first line in FIG. This means that the processing of the Yal register, Yb1 register, Xal register, and Xb1 register in the figure has been completed. Thereafter, as shown in step C15, the same applies to the second and subsequent data rows in FIG. Is repeatedly executed. When the detection of the data columns for all the data rows detected in FIG. 6 has been completed, the data column detection processing of FIG. 7 ends.

Thus, by combining the coordinate data of each row area and the coordinate data of each column area stored in the Ya register, Yb register, Xa register, and Xb register of the work area 25d, the coordinate data of the block area can be detected. is there. For example Yal Register Figure 9, Yb1 register coordinate data "y _128" row region "y _240" and Xal register, the coordinate data "x _80" "x _144" in column area of Xb1 register (y
_{128, x 80), (y} 128, x 144), (y 240, x 80), (y 240, x
₁₄₄ ) It is detected as an image block having four points indicated by coordinates as corners.

FIG. 10 shows a set of coordinate data of a block area obtained from the coordinate data shown in FIG. 9, and the coordinate data obtained by setting these four points as one set corresponds to the set corresponding to the number of blocks. It is stored and set in the area 25d.

Since the detection of the block coordinates is completed when the detection of the data presence column is completed, the first block in the image data displayed on the display unit 30 is blinked so as to prompt the block designation and the item input. After, then step in Figure 5
Proceeding to A04, the process of specifying the valid image block and inputting the items is performed.

FIG. 8 shows the details of the processing of the block designation and item input. In the state where the block is blinking, the character / numerical key 16 and the not-shown feed key and the cursor keys 16a, 16b and the item key 17 are displayed. This is a process that is executed when one of them is operated.

For example, when the first block "A" of the image data shown in FIG. 13 is blinking and displayed, a cursor key (indicated by "" in the figure) 16b for instructing a rightward cursor movement of the character / number keys 16 is pressed. When operated, this operation executes this process. First, it is determined whether or not the operated key is a not-shown feed key in the character / numerical key 16 as shown in step D01. This feed key is for simply moving the blinking position of the block. Here, the determination result is NO, and the process proceeds to step D03. At step D03, it is determined whether or not the operated key is the cursor key 16a of the character / numerical key 16, and the determination result is NO again, and the process proceeds to step D05. When it is determined that the key operated in step D05 is the cursor key 16b, the process proceeds to step D06. In step D06, the block of the character "A" that was initially blinking and the block of the character "B" adjacent to the right thereof are blinked together with the operation of the cursor key 16b as one block again, and are stored in the work area 25d. the coordinate data stored by that intended to change setting, in this case, the coordinates of the corner 4 points of a block letter 'a' _{(y 128, x 80),} (y 128, x 144), (y
_240, x _80), (a y _240, x _144), the coordinates of the corner 4 points of the blocks of the letter "B" _{(y 128, x 208),} (y 128,
x ₂₇₂ ), (y ₂₄₀ , x ₂₀₈ ), and (y ₂₄₀ , x ₂₇₂ ), the coordinates of the four corners of the block of the character “AB” after the change setting are (y ₁₂₈ , x ₈₀ ), (y _{128, x 272), (y} 240, x 80), (y
₂₄₀ , _x272 ). In addition, with the change of the coordinate data, the blinking position of the block is changed again, and the block of the single character "AB" is blinked and displayed, and the processing in FIG. 8 is completed.

Thereafter, by operating the cursor key 16b again, the processing of FIG. 8 is executed, and by the same processing contents as described above, the change setting of the coordinate data is performed with the character "ABC" as one block.

Next, when the feed key in the character / numerical key 16 is operated, the key operation is determined in step D01, and the process proceeds to step D02. In step D02, the position of the blinking display is moved to specify the next block. Since the block of the character "ABC" has been blinking displayed here, the block of the character "open" blinks next. This is the end of the process.

Thereafter, by appropriately operating the cursor key 16b and the feed key, the same processing as described above is repeatedly executed, and the effective image blocks in the image data are integrated as shown in FIG. Further, the coordinate data of the image block in the work area 25d is changed and set as shown in FIG. 11 by the processing of FIG.

If it is determined that the key operated in step D03 is the cursor key 16a, the process proceeds to step D04, where the blinking block and the block adjacent to the block below are blinked again. The coordinate data stored in the work area 25d is changed and set as one block. With the change of the coordinate data, the blinking position of the block is also changed again, and the one block is blinked and displayed, and the processing of FIG. 8 is completed.

After designation of blocks for integration in this way, input setting of item data for each block is performed.

The input setting of the item data is made by operating one of the item keys 17 after designating the corresponding block with the feed key.

Here, the "company" key of the item key 17 is operated while the position of the character "ABC", which is the first block, is blinking and displayed by the feed key. The process of FIG. 8 is executed again by this key operation, and after it is determined in step D01, D03, and D05 that the key operation is not the key operation by the feed key and the cursor keys 16a and 16b, the operation is performed as shown in step D07. It is determined whether the item key 17 is a “company emblem” key. Here, the determination result is NO, and then step D0
It is determined whether or not the item key 17 operated by proceeding to 9 is a “name” key. Here also, the determination result is NO, and the process proceeds to step D11 and the operated item key 17 is "Company".
It is determined whether it is a key. If it is determined that the key is the "company" key, the process proceeds to step D12, where the work area 25d in which the coordinate data of the first block is stored.
The item data "3" indicating "company" is stored as item data to be stored in the item data storage unit Id of the index storage unit 25c in a storage process described later at a position corresponding to the coordinate data of "3".
Enter and set. Thereafter, the next second block, that is, the block of the character string "development headquarters development room" is blinked and displayed instead of the first block currently blinking, and the input of the item data is urged to end this processing.

Next, when the "other" key of the item key 17 is operated while the second block "development headquarters development room" is blinking, the processing of FIG. 8 is performed by the operation. Here, first, the keys 17 operated in each of steps D01, D03, D05, D07, D09, and D11 are a feed key, a cursor key 16a,
16b, after it is determined that none of the “company emblem” key, “name” key, and “company” key are present, proceed to step D13 to determine whether the operated key is the “address” key of item key 17 Is determined. The determination result is NO, and the process proceeds to step D15 to determine whether the operated key is the "TEL" key of the item key 17. Again, if the decision is NO,
The remaining key is only the "other" key of the item key 17, so that the operated key is recognized as the "other" key, and then the process proceeds to step D17, where the coordinate data of the second block is Item data "6" indicating "other" as item data to be stored in the item data storage unit Id of the index storage unit 25c in a storage process described later at a position corresponding to the stored coordinate data of the work area 25d.
Enter and set. Then, the second blinking display
Instead of the third block, the next third block, that is, the block of the character string "room length" is displayed blinking, the input of the item data is prompted, and this processing ends.

When the “other” key of the item key 17 is operated in a state where the third block “room manager” is blinking, the same processing is executed again by the operation, and the third processing is executed.
In the position corresponding to the coordinate data of the work area 25d in which the coordinate data of the second block is stored, “other” is set as the item data to be stored in the item data storage unit Id of the index storage unit 25c in a storage process described later. After the item data "6" indicating the input is set, the next fourth block, instead of the currently blinking third block,
That is, the block of the character string "Ichiro Ito" is displayed in a blinking manner, input of the item data is prompted, and the process is terminated.

When the "name" key of the item key 17 is operated in the state where the fourth block "Ichiro Ito" is blinking, the processing in FIG. 8 is performed by the operation. Here, it is determined that the key 17 operated in step D09 via steps D01, D03, D05, and D07 is the "name" key of the item key 17,
Next, proceeding to step D10, the item data storage unit I d of the index storage unit 25c is stored in a position corresponding to the coordinate data of the work area 25d in which the coordinate data of the fourth block is stored by a storage process described later. The item data "2" indicating "others" is input and set as the item data to be stored in. After that, the next fifth block, that is, the block of the character string “TEL 03 (525) 1112” is blinked instead of the fourth block that is currently blinking,
The user is prompted to input the item data, and the process ends.

When the "TEL" key of the item key 17 is operated while the fifth block is blinking, the processing of FIG. 8 is performed by the operation. Here, step D15 is performed via steps D01, D03, D05, D07, D09, D11, and D13.
Is determined to be the "TEL" key of the item key 17, and the process proceeds to step D16, where the coordinate data of the fifth block is stored in the work area.
Item data “5” indicating “TEL” is input and set at a position corresponding to the coordinate data of 25d as item data to be stored in the item data storage unit Id of the index storage unit 25c in a storage process described later. Thereafter, when it is determined that the fifth block currently blinking is the last block, the processing in FIG. 8 is terminated.

The key operated in step D01 is item key 1
If it is determined that the key is the "company emblem" key of item 7, item data "1" indicating "company emblem" as item data at a position corresponding to the coordinate data of the work area 25d in which the coordinate data of the block is stored. However, if it is determined that the key operated in step D13 is the “address” key of the item key 17, the key is moved to a position corresponding to the coordinate data of the work area 25d in which the coordinate data of the block is stored. Item data “4” indicating “address” is input and set as item data.

As described above, when the item data has been set in the last block by the processing in FIG. 8, the processing in FIG. 8 ends, and at the same time, the processing in step A04 in FIG.
It reaches 05.

In step A05, 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 temporarily stored in a predetermined position of the display data storage unit 25a and the image data temporary storage unit 25e, that is, in a storage area different from the storage area of the image data, and the display data storage unit 25a Is displayed on the display section 30 with the contents of Next, it waits for a registration confirmation instruction by operating the execution key 15 in step A06. When the execution key 15 is operated, the process proceeds to step A07, in which only the data within the area defined by the coordinate data of the effective block in the image data held in the display data storage unit 25a is stored in the image data storage unit. 25b, and stores the coordinate data of the work area 25d in the coordinate data storage section Ic of the corresponding area of the index storage section 25c, and the item data according to FIG. 8 in the item data storage section Id. The address on the image data storage unit 25b is set in the storage unit Ib, and the index data held in the image data temporary storage unit 25e is also stored in the index data storage unit.
It is stored and set to Ia.

The image data of one business card is stored in the image data storage unit 25b by the above-described registration processing, and the address, the coordinate data at the time of display, and the item data on the image data storage unit 25b are stored in the index storage unit 25 together with the index data.
One of c, is stored, for example area I _0. Thereafter, each time a business card image is read, the image data is stored in the image data storage unit 25b, and the index data, the address on the image data storage unit 25b and the coordinate data for display,
Item data is stored in areas I ₁ , I ₂ , I ₃ ,.

Next, processing for searching for arbitrary image data from a large number of image data stored in the RAM 25 will be described.
There are three methods for performing a search. One is a method of inputting index data as before, the other is a method of simply operating a sequential key (not shown) provided on the character / numerical key 16, and the other. One is the above item key
This is a method of operating a sequential key after specifying a specific item with any one of the 17 keys.

As a normal method of inputting the first index data, first, the mode switch 14 is set to the “search” mode, and then the index data of the desired image data is key-input by the character / numerical key 16. By the key input, the processing of FIG. 5 is executed again.
At the beginning, if it is determined in step A01 that the mode is the "search" mode, the index data input in the subsequent step A08 is temporarily stored in the image data temporary storage unit 25e of the RAM 25. After waiting for the execution key 15 to be operated in the subsequent step A09, each area I ₀ ,
From the index data storage units Ia of I ₁ , I ₂ ,... Then, it is determined whether or not there is a match in step A10.
To read the coordinate data of the effective block corresponding to the index data from the index storage unit 25c,
Further, the image data is read from the image data storage unit 25b according to the address storage unit Ib, and the image data read according to the coordinate data stored in the coordinate data storage unit Ic is returned to the original position in the display data storage unit 25a. And the display is output on the display unit 30 to end the processing.

If it is determined in step A09 that there is no image data having the index data matching the input index data, the process proceeds to step A12, and an error display indicating that there is no matching data is displayed on the display unit.
The process is performed at 30 and the process ends.

Next, a method of performing a search by operating only the sequential key provided on the second character / numerical key 16 will be described.

If only the sequential key is operated with the mode switch 14 set to the "search" mode,
After it is determined in step A01 that the mode is the "search" mode,
It is recognized that the key operated in step A15 is a sequential key, and the process proceeds to step A16.
In step A16, it is determined whether or not the M flag register of the work area 25d of the RAM 25 is "0". The item data is set in the M flag register when the item is designated by the item key 17, and since the item is not designated here, it is "0", so the judgment result is YES, Next, the process proceeds to step A17.

In step A17, each area I ₀ ,
Coordinate data storage units I stored in I ₁ , I ₂ ,.
With c and the item data storage unit Id, all individual image data are sequentially and sequentially displayed in a unified format, and the processing is completed as described above. In this case, each image data to be displayed is displayed in a unified format according to the item data. Therefore, by sequentially operating the sequential keys, the same image data is displayed at the same position on the screen of the display unit 30 in any image data. The item data is displayed, and the user can search for desired image data without moving his / her gaze.

Lastly, a search method in which a specific item is designated by any one of the item keys 17 and a sequential key is operated will be described.

When any one of the item keys 17 is operated in a state where the mode changeover switch 14 is set to the "search" mode, it is determined that the mode is the "search" mode in step A01, and then the input by the item key 17 is performed in step A13. Is recognized as
Next, the process proceeds to step A14. In step A14, item data corresponding to any of the operated item keys 17 is input and set in the M flag register of the work area 25d of the RAM 25,
This ends the processing. The contents of the setting are almost the same as the processing shown in FIG. 9 described above. The key is “1” for the “company” key, “2” for the “name” key, “3” for the “company” key, and “address”. The key is "4", the "TEL" key is "5", and the "other" key is "6".

When the sequential key of the character / numerical key 16 is operated after setting the items in this manner, the fifth key is operated by the operation.
After the mode switch 14 is determined to be in the "search" mode in step A01 in the figure, the key operated in step A15 is recognized as being a sequential key, and the process then proceeds to step A16. In step A16, RAM 25
It is determined whether or not the M flag register of the work area 25d is “0”. Here, since the item data of any one of “1” to “6” is set in the M flag register by the processing of step A14, the determination result is NO,
Next, the process proceeds to step A18.

In step A18, the item specified by the contents of the M flag register in the work area 25d is determined. In the subsequent step A19, the item data Id stored in the respective areas I ₀ , I ₁ , I ₂ ,... Of the index storage unit 25c of the RAM 25 are searched according to the determination result, and the address corresponding to the matching item data is searched. Read from the address storage unit Ib. Then, a plurality of image data blocks of a desired item are read from the image data storage unit 25b based on the read address, numbered, displayed on the display unit 30, and the process is completed.

FIG. 15 shows a display example when the user operates the sequential key after selecting and specifying the “name” key from the item keys 17. As described above, only the image data of the designated item is sequentially displayed on the multiple display unit 30.

In the above embodiment, an example is shown in which an image of a business card is read and stored as image data, and this is displayed and output.
It goes without saying that the present invention is not limited to the business card image, and any other image can be stored by the same processing.

In the above embodiment, the line sensor is used for image reading. However, it goes without saying that a dot matrix type full sensor that reads all image data at the same time may be used, and various modifications and changes may be made without departing from the gist of the present invention. Application is possible.

Further, in the above embodiment, the bit content of the display data storage unit 25a is displayed as it is on the display unit 30, but, for example, the number of dots displayed on the display unit 30 is set to half of the bit content of the display unit 30, When the contents of the display data storage unit 25a are displayed every other row and every other column and the displayed contents are difficult to read, all the bit contents of the display data storage unit 25a may be displayed by, for example, display switching. Good thing. That is, in this case, enlarged display is possible.
