Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image data 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 such data are stored in a memory, a magnetic disk, or the like and storage means. An image data storage device that retrieves and reads arbitrary image data by designating index data in accordance with, and displays or outputs the image data is proposed. In this type of image data storage device,
A plurality of business card image data can be stored according to the capacity of the storage means.

[Problems to be Solved by the Invention] However, regardless of the amount of data, the image data is converted into a black and white binary image including a blank area and stored as it is. In the case of (1), the bit of the value "0" is stored, and when the effective image, that is, the black printing is performed, the bit of the value "1" is stored. 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 limited, so that only a limited number of data can be stored. .

Further, as described above, in addition to always storing and displaying image data in units of one sheet, the storage capacity of the storage means is one unit.
When it becomes full, unnecessary image data is erased one by one. Therefore, even if information that is partially necessary is included in specific image data, if the image data as a whole is infrequently used, the image data may need to be erased. obtain.

The present invention has been made in view of the above situation, and makes it possible to effectively use the capacity of a storage unit for storing image data, to store more image data, and to store more image data in the image data. It is an object of the present invention to provide an image data storage device capable of deleting only arbitrary image block data or image block data of an arbitrary item.

[Means and Actions for Solving the Problems] According to the present invention, image data is read by, for example, an image scanner or the like, and an effective image block of the read image data is written and stored in storage means together with its position information. By specifying an item name corresponding to each effective image block and storing it, and specifying an unnecessary item name when erasing, the effective image block corresponding to the specified item name and its position information are identified. All of them are erased from the above storage means, while effectively utilizing the capacity of the memory for storing image data to store more image data,
Only unnecessary image data portions can be deleted.

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

FIG. 5 shows the contents of the registration processing of the control unit 32 corresponding to the key operation of the registration key 14, and at the beginning, the image data is read as shown in step A01. As shown in FIG. 2, the reading unit 20 is brought into contact with the upper surface of a business card 22 to be read, and the scanning is performed on the business card 22 while the reading switch 21 is kept pressed. Are read by the line sensor 38 in units of one line, and the pixel portion is sequentially sent to the control section 32 via the reading control section 36 as “1” data and the blank section as “0” data. In the control unit 32, the image data in the line unit sequentially sent is temporarily stored in the image data temporary storage unit 35e of the RAM 35, and is also stored in the display data storage unit 35a, and is sent to the display control unit 37 as display data. It is displayed on the display unit 39. 1
The image data of the business card 22 for the number of sheets is temporarily stored in the image data storage section 35e.
After being stored in the display data storage unit 35a, the control unit 32 performs detection and storage processing of the block coordinates of the effective image data portion using the image data stored in the image data temporary storage unit 35e as shown in step A02. .

FIG. 6 shows a flowchart of the processing contents of the detection and storage of the block coordinates. First, as shown in step B01, a row of the image data is determined by the bit map of the image data stored in the image data temporary storage unit 35e. To detect. That is, in the image data stored in the image data temporary storage unit 35e, the blank bit is stored as "0" and the black pixel (printed) is stored as "1".

Thus, the lateral coordinate of the bitmap image data temporary storage section _{35e x 0, x 1, x} 2, x 3, ..., in the vertical direction coordinate y _0, y _1,
If y ₂ , y ₃ ,..., each row has at least one pixel data “1” in the horizontal direction having the same y coordinate as a row and the vertical direction having the same x coordinate as a column The detection means is as shown in FIG.

That is, FIG. 7 shows the contents of this data validity detection processing. At the beginning of the processing, the control unit 32 initializes at step C01 the X register and the Y register (not shown) of the work area 35d of the RAM 35 to "0". ". Next, at step C02, the X register is updated and set to "+1". In the following step C03, it is determined whether or not the column position corresponding to the contents of the X register is the last column on the bit map. Here, since the X register is “1”, the determination result is NO. Then, the process proceeds to step C04 to determine whether the bit of the pixel data is “1” at the coordinate position indicated by the contents of the X register and the Y register. to decide. If the value is not "1", the flow returns to step C02 again, and the content of the X register is again changed to "+
1 "and repeat the above processing again.

If it is determined in step C04 that there is pixel data "1", there is at least one pixel data "1" in the row, and the process proceeds from step C04 to step C05, where the contents of the Y register at that time, that is, storing y-coordinate with the data in the Y ₀ register (not shown) of the work area 35d. Then, in step C06, the content of the Y register is changed to "+
"1" is updated and the X register is cleared to "0". Here, it is determined in step C07 whether or not the row position corresponding to the updated contents of the Y register is the last row on the bit map. After it is determined that the row position is different, whether or not there is data in the next row is determined. Step C02 again to detect
The processing from is performed. Thus it is determined whether at least one of a pixel data "1" in each row, continue to store the Y ₀ registers its y coordinate data sequentially work area 35d, if any.

When it is determined in step C07 that the row position corresponding to the contents of the Y register is the last row on the bit map, the data row detection on the bit map of the image data temporary storage unit 35e according to FIG. Has been completed.

When the detection of the presence of data in step B01 in FIG. 6 is completed, the process proceeds to step B02, where it is determined whether or not each column has at least one pixel data "1". The detecting means is almost the same as that of FIG. 7, and the control of the row and the column is performed by exchanging the control.
Wherein the detailed description is omitted, will be stored in the X ₀ register sequential work area 35d of the x-coordinate data of at least one pixel data "1" columns that.

FIG. 14 shows Y _{0 of the} work area 35d in which the y-coordinate data of the data row is stored in the case of the bit map as shown in FIG.
Storing x-coordinate data of the register and the data-stored sequence illustrates the storage state of the X ₀ register. As described above, the process of detecting the effective block coordinates shown in step B03 is performed using the coordinate data obtained by scanning the bit map of the display data storage unit 25a in both the vertical and horizontal directions in steps B01 and B02.

Figure 8 is shows the details of the detection process of the effective block coordinates in step B03, Y ₁ registers y _m registers of the work area 35d as first shown in step D01, the y _n registers, as shown in FIG. 14 storing set as indicating the first row coordinate data "y _16" stored in Y ₀ register in the same work area 35d in FIG. 15. After setting the initial value "0" to G register (not shown) in the work area 35d for counting the distance between the blocks in the next step D02, "+1" values of y _n registers in step D03 updated set "Y ₁₇ "
In the subsequent step D04, the value is stored in the display data storage unit 25a.
It is determined whether or not this is the last row on the bit map of NO
Then, the process proceeds to step D, where it is determined whether or not the y coordinate data that matches the y _n register value “y ₁₇ ” is stored in the Y ₀ register. In this case, since the data is stored, the determination result is YES, the G register is cleared in the subsequent step D06, and the processing from step S03 is repeated again.

Thus while sequentially updated and set the value of y _n registers, continue to search for the last row address in the same block. When coordinate data matches the value of y _n register is not stored in the Y ₀ register, Step D Step D05
In step 07, the contents of the G register are updated and set to "+1".
Thereafter, in step D08, it is determined whether or not the content of the G register is "16". If not, the process from step D03 is repeated again. Thereafter, while sequentially updating and setting the value of the register y _n ,
It is counted by the counter.

The G register counts row coordinates with no continuous data, and when the count value reaches a certain number “16”,
This is for recognizing that an image block has been cut off and has become a blank area. Here, the fixed number “16” is a value indicating that, if the resolution of the line sensor 38 is, for example, 8 dots / mm, rows without images continue over 2 mm.

Thus, when the count value of the G register is determined to be "16", then the value of y _n registers in step D09 is "-16", it is returned to the row coordinate data with data.

Thereafter, the next data-stored row coordinate data stored in step D10 to Y ₀ register is Y ₁ registers y _m registers, y _n
The register is newly newly set, and this additionally set y _n
The processing from step D02 is repeatedly executed again on the contents of the register.

Thus, the Y ₁ registers work area 35d, a set of row coordinate data indicating a region of a data line is sequentially stored. Figure 12 is illustrative of the image data of the business card 22, a set of row coordinate data together indicating a region of the rows of the block indicated by broken lines will be stored sequentially Y ₁ register. No. 16
Figure stored in Y ₁ registers work area 35d, indicates the area of the row coordinates of the valid image blocks, for example the
Image data as shown in FIG. 12, corresponding to 4 point Z ₀ to Z ₃ in the first block to the corner regions "y _16" of the row coordinates in which "y _56" is stored is there.

Repeat the process of step D02～D10, after all stores the area of the row coordinates of the effective image blocks Y ₁ register, the value of y _n register is determined to be the last line in step D04 , then proceeds to step D11, the detected row region above "y ₁₆ ~y _56", "y ₁₃₆ ~y _200", "y
_{224 to} y ₂₅₆ ",..., A certain column coordinate of the image data is searched in the same manner as the above-described detection of the row coordinate, and the minimum coordinate data and the maximum coordinate data are respectively searched in step D12.
In stores to x _m registers and x _n registers X ₁ registers work area 35d.

In which the coordinate data of the block area can be detected by thus combining the coordinate data of each row region stored in the coordinate data and X ₁ register of each row region stored in Y ₁ registers work area 35d . For example, the twelfth
In the first block having four points Z _{0 to} Z ₃ as the corners in the figure, the coordinates of the four points Z _{0 to} Z ₃ are the coordinate data “y ₁₆ ” of each row area.
The coordinate data "y _32" of each row region and "y _56" "y _{112"
Z 0 (y 16, x 32} ), Z 1 (y 16, x 112), Z 2 (y 56, x 32), Z
It is detected as _{3 (y 56, x 112)} .

The coordinate data of each block obtained in this way is
In the following step D12, the data is stored in the index storage unit 35c of the RAM 35. FIG. 17 shows the storage state. In the index storage unit 35c, the coordinate data for the four points of the block as one set are stored and set for the set corresponding to the number of blocks. The valid block coordinate detection processing ends.

When the processing for detecting the coordinates of the effective block is completed, the processing for detecting and storing the block coordinates in FIG. 6 is completed.

Thereafter, the process proceeds from step A02 to step A03 in FIG. 5, and the control unit 32 waits for input of index data by the character / numerical key 19 of the key input unit 31. When the index data is input, the index data is also temporarily stored in a predetermined position of the image data temporary storage unit 35e and the display data storage unit 35a, that is, in a storage area different from the storage area of the image data, and displayed. Next, step A04
Waits for an instruction to confirm the registration by operating the execution key 17 in. When the execution key 17 is operated, the process proceeds to step A05, and only the data within the area defined by the coordinate data of the effective block in the image data held in the image data temporary storage unit 35e is stored in the image data. In addition to the transfer to the unit 35b for storage, the address on the image data storage unit 35b is set in the corresponding address storage unit Ib of the index storage unit 35c. The index data held in the image data temporary storage unit 35e is also stored and set in the index data storage unit Ia of the index storage unit 35c.

The image data of one business card is stored in the image data storage unit 35b by the registration process described above, and the address, coordinate data and item data at the time of display on the image data storage unit 35b are stored in the index storage unit 35 together with the index data.
One of c, is stored, for example area I _0. Thereafter, each time a business card image is read, as shown in FIG. 5, the image data is stored in the image data storage unit 35b, the index data, the address on the image data storage unit 35b, the coordinate data at the time of display, and the item. The data is stored in areas I ₁ , I ₂ , I ₃ ,.

Next, a process for searching for arbitrary image data from a large number of image data stored in the RAM 35 will be described.
There are two methods for performing the search. One is a method of operating the sequential key 18, and the other is a method of inputting index data.

A method of performing a search by operating the first sequential key 18 will be described.

FIG. 9 shows a sequential search process by operating the sequential key 18. At the beginning of the process, the key operated in step E01 is recognized as the sequential key 18, and the process then proceeds to step E02. Step E02
First, the first area of the index storage unit 35c of the RAM 35
The contents of the coordinate data storage unit Ic and the address storage unit Ib stored in _I0 are read, the image data is read from the corresponding address of the image data storage unit 35b, sent to the display control unit 37, and displayed on the display unit 39. .

Thereafter, every time the sequential key 18 is operated, the area of the index storage section 35c is updated and set in step E02 of FIG. 9, and the coordinate data storage section Ic stored in the areas I ₁ , I ₂ ,. Then, the contents of the address storage unit Ib are read, and the image data is sequentially read from the corresponding address of the image data storage unit 35b, sent to the display control unit 37, and displayed on the display unit 39.

Next, a method of searching by inputting index data will be described.

FIG. 10 shows a direct search process for index data input by the character / numerical key 19. At the beginning of the process, it is recognized in step F01 that the key input is index data by the character / numerical key 19, and the index data is The image data is temporarily stored in the image data temporary storage unit 35e of the RAM 35 and is also stored in the display data storage unit 35a to be displayed on the display unit 39 via the display control unit 37. Then, the process proceeds to step F02. After waiting for the operation of the execution key 17 in step F02,
When the execution key 17 is operated, the process proceeds to step F03, where index data matching the input index data is stored in the index data storage unit I ₀ of each area I ₀ , I ₁ , I ₂ ,... Of the index storage unit 35c. Search for If there is, the process proceeds to step F04, in which the coordinate data of the effective block in the area of the matched index data is stored from the coordinate data storage unit Ic, and the address position of the image data in the image data storage unit 35b is stored in the address storage unit Ib. Read from
The image data is read out from the corresponding address in the image data storage unit 35b and sent to the display control unit 37, and displayed on the display unit 39 as an image whose index data matches, and this processing is completed.

If it is determined in step F03 that there is no image data having index data that matches the input index data, then in step F05, an error display indicating that there is no matching data is displayed on the display unit 39. This processing is completed.

Next, an operation for clearing (erasing) unnecessary image data will be described.

When clearing unnecessary image data, the clear key 16 is first set by operating the clear key 16 with the image data to be cleared by the above search processing displayed on the display unit 39. At this point, the first valid image block in the image data has been designated, and if it is desired to clear this first valid image block, the clear key 16 is subsequently operated.

The operation of the clear key 16 is determined to be the clear key 16 in step G01 of the clear processing shown in FIG. In step G02, the first valid image block is selected and blinked to prompt execution of clearing.

When the execution key 17 is operated in response to the flashing display, the clear processing shown in FIG. 11 is performed again by the operation of the execution key 17, and the key operated in step G01 is the clear key 1
After it is determined that it is not 6, the process proceeds to Step G03. In step G03, it is determined whether or not the operated key is a block step key for designating the image block at the next position. This block advance key is provided in the character / numerical key 19. Here, the determination result is NO, and the process proceeds to step G05, where it is confirmed that the operated key is the execution key 17, and then the next step is performed. In step 06, the coordinate data and image data of the selected effective image block are deleted from the corresponding areas of the image data storage unit 35b and the index storage unit 35c, and the coordinates of the effective image block are also read from the display data storage unit 35a. The data is deleted, and the display of the image block blinking on the display unit 39 is deleted. afterwards,
In step G07, as post-processing of the erasure, the image data storage unit 3
5b, the contents are arranged by sequentially filling the previous address positions below the blank portion due to the erasure of the index storage unit 35c, and the process is completed.

To erase an image block other than the currently blinking image block, the block advance key is operated. When the block advance key is operated, it is determined that the key operated in step G03 through step G01 is the block advance key, and then step G04
The image block located next to the currently blinking image block is selected instead, and blinks. Therefore, if the block advance key is operated continuously the required number of times, the flashing display block position is moved to a desired position, and then the clear key 16 and the execution key 17 are operated, the effective image block is displayed. Image data can be lost.

Second Embodiment Hereinafter, a second embodiment in which the present invention is applied to a business card file device will be described with reference to the drawings.

FIG. 18 shows the external configuration, and the basic external configuration, circuit configuration, and the like are the same as those shown in the first embodiment. The same portions are denoted by the same reference numerals and description thereof will be omitted.

Thus, inside the lower case 11b, besides a sequential key 18 for performing a sequential search, a character / numerical key 16 for inputting index data, etc., a "company" key for inputting and specifying items , "Name" key, "Address" key, "Mark" key, "TEL (telephone number)" key and "Other" key item key 23
Is provided.

The item keys 23 are used to add and set item name data to the image blocks by specifying and inputting the corresponding image blocks when registering the image data. In order to store the item name data, in the index storage unit 35c of the RAM 35, in addition to the index data storage unit Ia, the address storage unit Ib, and the coordinate data storage unit Ic in each of the areas I ₀ , I ₁ , I ₂ ,. , As shown in FIG. 19, an item data storage section Id for storing item data.

In the above configuration, the operation when registering image data is as shown in FIG. That is, at the beginning, image data is read as shown in step H01. The read image data of the business card 22 is sequentially stored in the image data temporary storage unit 35e of the RAM 35, and is also stored in the display data storage unit 35a, and is displayed as display data by the display control unit 3.
7 and displayed on the display unit 39.

Image data of one business card 22 is temporarily stored in the image data storage unit.
After being stored in the display data storage unit 35a and the display data storage unit 35a,
As shown in H02, the detection and storage processing of the block coordinates of the effective image data portion is performed using the image data held in the image data temporary storage unit 35e.

At the end of the block coordinate detection and storage processing, the first block in the image data displayed on the display unit 39 is flickered to prompt entry of item data.

After that, the process proceeds to Step H03 to perform an input process of item data for each image block. This item input processing is performed by operating any of the item keys 23 in a state where the block is blinking. For example, when the first block of the image data is blinking and displayed, the “company” of the item key 17 is displayed. Key, it is determined that the item key 17 operated by the operation is the "company" key,
“1” is set as the item data indicating “company” in the storage unit Id in the item data at the position corresponding to the coordinate data storage unit Ic of the index storage unit 35c in which the coordinate data of the first image block is stored. Is done. Thereafter, the next block is blinked and displayed instead of the first block currently blinking, and the input of the item data is urged to end this processing.

Hereinafter, similarly, by operating any one of the item keys 23 for the second and subsequent image blocks, the item data indicating this item corresponds to the coordinate data storage unit Ic of the index storage device c. The input is set in the item data storage unit Id at the position.

FIG. 19 shows the state of the index data storage unit 35c corresponding to the image data, the coordinate data storage unit Ic, and the item data storage unit Id.In addition to the coordinate data shown in FIG. 17, the item data storage Item data "1""2" in the section Id
"3" and "5" indicate the state in which the settings are stored.

When the item input processing is completed, the process proceeds to step H04, and waits for input of index data by the character / numerical key 19 of the key input unit 31. When the index data is input, the index data is also stored in the temporary storage unit 35.
e and a predetermined position of the display data storage unit 35a, that is, once in a storage area different from the storage area of the image data, and displayed. Next, it waits for a registration confirmation instruction by operating the execution key 17 in step H05. When the execution key 17 is operated, the process proceeds to step H06, where only the data within the area defined by the coordinate data of the effective block in the image data held in the temporary storage unit 35e is stored in the image data storage unit.
35b and store it in the index storage unit 3.
The image data storage unit 35b is stored in the corresponding address storage unit Ib of 5c.
The above address is set. The index data held in the temporary storage unit 35e is also stored in the index storage unit 35c.
Is stored in the index data storage unit Ia.

The image data of one business card 22 is stored in the image data storage unit 35b 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 35b are stored in the index storage unit together with the index data.
One 35c, is stored in, 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 35b, and the index data, the address on the image data storage unit 35b and the coordinate data for display,
Item data is stored in areas I ₁ , I ₂ , I ₃ ,.

Next, a description will be given of a process of collectively clearing only data of an arbitrary item from among a large number of image data stored in the RAM 35. If you want to erase,
As shown in FIG. 21, first, in step I01, the clear key 1
After the clear mode is set by operating 6, the item key 23 of the item desired to be erased is operated. The item data corresponding to any of the item keys 23 operated in the work area 35d by this key operation is temporarily held, and in the following step I02, the user waits for the clear key 16 prompting the execution of the erasure to be operated. Later, in step I03, the index storage unit 35c
, All of the item data stored in the item data storage unit Id of each of the regions I ₀ , I ₁ , I ₂ ,. Then, all the coordinate data of the effective image block corresponding to the item data is deleted from the index storage unit 35c, and all the image data is deleted from the image data storage unit 35b according to the address storage unit Ib.

Then, as post-processing of the erasure in step I04, the portions below the blank portions in the areas I ₀ , I ₁ , I ₂ , I ₃ ,... Due to the erasure of the image data storage unit 35b and the index storage unit 35c are deleted. This process is completed by sequentially packing the data at the previous address position.

In the first and second embodiments, an example in which a business card image is read and stored as image data and displayed and output is shown. However, the present invention is not limited to a business card image, and any other image may be used. Can be stored by the same processing.

In the above embodiment, the line sensor is used for image reading. However, it is a matter of course that a dot matrix type full sensor for reading 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.

[Effects of the Invention] As described in detail above, according to the present invention, for example, image data is read by an image scanner or the like, and an effective image block of the read image data is written and stored in storage means together with its position information. , Specify the item name corresponding to each effective image block and store it.
When erasing, an unnecessary item name is designated, and all the effective image blocks corresponding to the designated item name and their position information are erased from the storage means. It is possible to provide an image data storage device capable of storing a large amount of image data by effectively utilizing the capacity of the image data and deleting only unnecessary image data portions.
