However, it is not easy for a human to actually draw a figure exactly as he or she uses an electronic pen. For example, in a conventional tablet, when trying to draw a straight line, even if the operator intends to draw a straight line, it is often input as a jagged line instead of a straight line. Furthermore, in a conventional tablet, if it is desired to draw a straight line as accurately as possible, it is necessary to carefully move the electronic pen, and there is a problem in that drawing takes time. Although it is possible to draw a straight line using a tool for drawing a straight line such as a ruler, there is a problem that a tool for drawing a straight line is required or it takes time and effort.

The user data includes personal information such as an ID number, an address, a name, and a date of birth. These pieces of personal information are input by the operator at the registration terminal 1.
[0015]
Further, in the registration terminal 1, when characters such as personal information are input, information input by an operator is converted into character image data based on predetermined font information. That is, for example, a character such as a kanji having a JIS code is converted into character image data as predetermined font information registered in a memory (not shown) in advance. On the other hand, characters for which the predetermined font information does not exist are input as missing characters. In the registration terminal 1, the above-mentioned missing characters are converted into identifiers indicating missing characters, such as "*", and are input.
[0016]
The host computer 2 stores user data including personal information input by the registration terminal 1. The host computer 2 has a database (not shown), and stores the user data input by the registration terminal 1 in the database.

It has become.
[0019]
Next, the internal configuration of the missing character terminal 3 will be described in detail.
As shown in FIG. 1, the character missing terminal 3 has a control unit 11, a keyboard 12, a tablet 13, a storage unit (storage unit) 15, a communication unit (acquisition unit) 16, and the like.
The control unit 11 includes a CPU operated by a control program, a memory storing a control program, and the like, and controls the entire photographing apparatus. The keyboard 12 is used by an operator to input operation instructions and data.
[0020]
The tablet (drawing input device) 13 is used by an operator to input handwritten image data of missing characters. As shown in FIG. 2, the tablet 13 includes a liquid crystal display device D as a writing board and a display device, a pen-shaped stylus (hereinafter, referred to as an electronic pen) P as a pointing device (handwriting input means), and controls. And a circuit mechanism for performing the above. The circuit mechanism is configured by a control circuit that realizes functions such as a memory as a storage unit, a determination function as a determination unit, and a correction function as a correction unit. Note that the storage unit may be realized by the storage unit 15, and the determination unit or the correction unit may be realized by the control unit 11.
[0021]
In addition, the liquid crystal display device D has a function as a detection unit that continuously (for example, every predetermined time) detects a point where the electronic pen P contacts a display surface (hereinafter, referred to as an input surface). I have. As a result, the tablet 13 continuously detects points where the electronic pen P has touched the input surface of the liquid crystal display device D, and acquires image data composed of a set of consecutive points handwritten by the operator.
[0022]
For example, in the tablet 13, by detecting the electronic pen P in contact with the input surface every predetermined time, image data as a set of points detected every predetermined time is acquired. Further, instead of the tablet 13, a pointing device (handwriting input means) such as the mouse, trackball, and touch screen and a display device for displaying operation guidance or input data may be used. In this case, an image handwritten by the operator may be acquired using the pointing device, and the input image may be displayed on the display device.
[0023]
The storage unit 15 is configured by a storage device such as a hard disk drive and a RAM, and stores data from the host computer 2 and the like. The communication unit 16 includes an interface device for performing network communication. The communication unit 16 performs data communication with the host computer (first registration unit) 2 or the missing character database (second registration unit) 4. The communication unit 16 has a function as an obtaining unit for obtaining user data including a missing character from the host computer 2 and a function of transmitting image data of the missing character to be registered in the missing character database 4. .
[0024]
Next, the missing character input processing by the missing character terminal 3 will be described.
FIG. 2 is a diagram showing a configuration of a system for inputting image data of a missing character in the missing character terminal 3. As shown in FIG. 2, the character missing terminal 3 includes a main body having the control unit 11, the storage unit 15, the communication unit 16, and the like, a keyboard 12 as a data input device, and a tablet 13 as a drawing input device. are doing.
[0025]
The tablet 13 has a liquid crystal display device D and an electronic pen P. The liquid crystal display device D has a function of displaying information in accordance with control from the main body and a function of detecting contact of the electronic pen P with a surface (input surface). The liquid crystal display device D has a display surface having matrices-like coordinates of 150 × 150 dots, and detects coordinates of a contact point with the electronic pen P. Further, the liquid crystal display device D detects a point of contact with the electronic pen P at predetermined time intervals.
[0026]
FIG. 3 is a diagram showing a display example of an input screen when a missing character is input by the missing character terminal 3.
When inputting a missing character, the operator uses the keyboard 12 to instruct the start of a missing character input operation. Then, the control unit 11 of the missing character terminal 3 requests the host computer 2 for user data including the missing character. On the other hand, when receiving the user data including the missing characters from the host computer 2, the control unit 11 displays the user data including the missing characters on the liquid crystal display unit D of the tablet 13, and also displays the user data including the missing characters. Display the display frame that displays the input image.
[0027]
For example, in the display example shown in FIG. 3, a personal information column 21, a missing character image display area 22, an input image display area 23, a registration button 24, and an end button 25 are displayed. The personal information column 21 displays an ID number (ID card number), an address, a name, a date of birth, and the like as information on the user based on the user data acquired from the host computer 2.
[0028]
In the missing character image display area 22, an image of a missing character (missing character image) having a size actually registered in the missing character database 4 is displayed. In the input image display area 23, an image of a missing character (input image) having the size input by the tablet 13 is displayed. In the case where the personal information includes a plurality of missing characters, the input image of the plurality of missing characters is displayed in the plurality of display fields on the same screen as shown in FIG. 23a, 23b, 23c,...
[0029]
The registration button 24 is a button selected by an operator when registering a missing character of the image displayed in the missing character image display area 22 and the input image display area 23 in the missing character database 4. The end button 25 is a button selected by the operator when ending the input operation of a missing character.
[0030]
For example, in the tablet 13, the image of the missing character is input in a size composed of 150 × 150 dot pixels, and the missing character database 4 stores the image of the missing character in the tablet 13 with 50 × 50 dot pixels. It is assumed that an image converted into an image having a size of is registered. In this case, the missing character image display area 22 displays a missing character image composed of 50 × 50 dot pixels, and the input image display area 23 displays a missing character image composed of 150 × 150 dot pixels. Is displayed.
[0031]
Next, the input operation of the image of the missing character by the tablet 13 will be described.
FIG. 4 is a diagram illustrating an example of a missing character image handwritten using the electronic pen P of the tablet 13. 4 and 5 show an image in a pixel area of 30 × 30 dots for the sake of simplicity, but in practice, for example, 150 × 150 dots It is assumed that an image is input in the pixel area of.
[0032]
FIG. 4 shows an example of an actual input image (input image without correction) when a character image such as “T” is input. Characters such as "T" include a horizontal straight line portion and a vertical straight line portion. When the character “T” is input by handwriting using the tablet 13, the operator draws a horizontal straight line and a vertical straight line on the input surface with the electronic pen P. In such a case, in the sense of a human, even if it is intended to draw a straight line on the input surface with the electronic pen P, a slight blur appears, so that the straight line is often distorted.
[0033]
That is, when the operator handwrites the character "T" with the electronic pen P as shown in FIG. 4, the input image as it is becomes a jagged line. For example, even if a blur of several dots in 150 × 150 dots is converted (reduced) to 50 × 50 dots, it may be drawn as a jagged line instead of a perfect straight line. Therefore, in the present embodiment, the position coordinates of each input pixel are determined, the position coordinates of the input pixels are corrected, and an image composed of the corrected position coordinates is drawn as an input image. .
[0034]
For example, an input image as shown in FIG. 4 is corrected to an input image as shown in FIG. In the example shown in FIG. 4, the character “T” consisting of a horizontal straight line and a vertical straight line is input by handwriting with the electronic pen P. However, the image of the horizontal straight line and the vertical straight line Is not entered as a perfect straight line. By correcting each pixel of a portion that can be determined as a straight line with respect to such an input image, the image of the portion that can be determined as a straight line is corrected to a complete straight line image. As a result, the actual input image shown in FIG. 4 is corrected to the image shown in FIG. The image to be drawn is a corrected image. For this reason, even when the image of the straight line is slightly blurred and input, the portion of the image to be drawn that is determined to be a straight line is a complete straight line.
[0035]
For example, when the pixel area of the input image on the tablet 13 is 150 × 150 dots, the X direction that is the horizontal direction and the Y direction that is the vertical direction are set with respect to the pixel area, and the image of the missing character is set. Is detected by the (X, Y) coordinates. The coordinate values of each pixel are corrected by comparing the detected coordinate values of each pixel.
[0036]
Next, a missing character input process including a process of correcting a missing character image input by the tablet 13 will be described.
FIG. 6 is a flowchart for explaining the missing character input processing of the tablet 13.
First, the missing character terminal 3 obtains personal information having a missing character from the host computer 2 by operating the keyboard 12. When the personal information having the missing character is acquired, the control unit 11 of the missing character terminal 3 inputs the acquired personal information and the missing character to the liquid crystal display unit D of the tablet 13 as shown in FIG. The display area 23 is displayed. In this state, the operator performs handwriting input of missing characters included in the personal information while referring to the applicant's application form and the like.
[0037]
That is, when the electronic pen P is brought into contact with the input image display area 23 corresponding to the missing character input by the operator, the tablet 13 starts a process of inputting the image of the missing character (missing character input process) (step). S11). In the missing character input process, the liquid crystal display unit D detects a point (pixel) on the input image display area 23 where the electronic pen P is in contact at every predetermined time (timing). The position of each pixel in the input image display area 23 is indicated by a coordinate value where the horizontal direction is the X direction and the vertical direction is the Y direction. Therefore, the liquid crystal display unit D detects a contact point (contact pixel) of the electronic pen P in the input image display area 23 at predetermined time intervals by using a coordinate value.
[0038]
That is, upon detecting the coordinates of the touch point of the electronic pen P in the input image display area 23, the tablet 13 temporarily stores the detected coordinate value (current coordinate value) of the touch point in a memory (not shown) (step S12). ). Note that the coordinates of the point touched at the start of input (first) are simply stored in the memory as determined coordinate values.
[0039]
When the coordinates of the detected contact point (current coordinate value) are stored in the memory, the tablet 13 stores the coordinate value of the contact point detected immediately before (the contact point detected immediately before) stored in the memory. If the coordinate value of (1) has been corrected, a comparison with the corrected coordinate value (previous coordinate value) is performed.
[0040]
That is, the tablet 13 has the X coordinate of the current contact point and the X coordinate of the contact point detected immediately before (the corrected X coordinate when the X coordinate of the contact point detected immediately before is corrected). And the difference between the X coordinate of the current contact point and the X coordinate of the contact point detected immediately before (the corrected X coordinate if corrected) is within a predetermined constant value (threshold). It is determined whether or not there is (step S13).
[0041]
When the tablet 13 determines that the difference between the two is within a predetermined fixed value (step S13, YES), the tablet 13 determines the value of the X coordinate at the current contact point as the X coordinate of the contact point detected immediately before. The value is replaced with a value (if corrected, the corrected X coordinate value) (step S14), and is determined as the X coordinate of the current contact point (step S15). When the tablet 13 determines that the difference between the two is not within the predetermined fixed value (step S13, NO), the tablet 13 determines the X coordinate of the detected contact point as the X coordinate of the current contact point. (Step S15).
[0042]
When the X coordinate of the current contact point is determined, the tablet 13 corrects the Y coordinate of the current contact point and the Y coordinate of the immediately preceding contact point (the Y coordinate of the immediately preceding contact point is corrected). Is compared with the corrected Y coordinate, and the difference between the Y coordinate of the current contact point and the Y coordinate of the contact point detected immediately before (the corrected Y coordinate if corrected) is calculated. It is determined whether it is within a predetermined value (step S16).
[0043]
When the tablet 13 determines that the difference between the two is within a predetermined fixed value (step S16, YES), the tablet 13 determines the value of the Y coordinate at the detected current contact point as the value of the previously detected contact point. The value of the Y coordinate (if corrected, the corrected Y coordinate) is replaced (step S17), and the current Y coordinate is determined (step S18). If it is determined that the difference is not within the predetermined value (step S16, NO), the control unit 14 determines the Y coordinate of the detected contact point as the Y coordinate of the current contact point. (Step S18).
[0044]
When the X coordinate and the Y coordinate are determined, the tablet 13 displays the pixel at the determined coordinate position in the input image display area 23 of the liquid crystal display unit D (step S19). The tablet 13 holds the determined X and Y coordinates in the memory as the coordinate values detected immediately before, and returns to step S11 to repeatedly execute the above processing.
An image that seems to be a straight line input by handwriting by performing the above-described processing for each point is input as a complete straight line image.
[0045]
That is, by comparing the coordinates of two consecutive points (or the corrected coordinates if the coordinates of the previously detected touch point of the two points to be compared have been corrected), the horizontal direction (X direction) is obtained. As a correction process for a straight line, if the shift amount in the vertical direction (Y direction) is within a predetermined fixed value, correction is performed so that the coordinates of two points in the vertical direction are the same. If the amount of displacement in the direction is within a predetermined fixed value, correction is made so that the coordinates of the two points in the horizontal direction are the same.
[0046]
Thereby, if the change amount of the coordinates of each continuous point is within a predetermined fixed value, the vertical position and the horizontal position are the same for each continuous point, and the vertical straight line and the horizontal An image input as a straight line in the direction can be corrected to a complete vertical straight line and a horizontal straight line.
[0047]
Further, in the example of the missing character input processing described above, the correction is performed by determining whether the deviation amount in the vertical direction (Y direction) and the deviation amount in the horizontal direction (X direction) are each within a predetermined fixed value. As described above, the correction may be performed by calculating the slope of a continuous point as a variation and determining whether the slope is within a predetermined range. In this case, it is possible to reliably determine whether or not the relationship between the consecutively input points is a straight line.
[0048]
For example, the tablet 13 detects points input with the electronic pen P at predetermined time intervals, and acquires a set of the detected points as an image. For this reason, when the operator moves the electronic pen P quickly to draw an image, the absolute interval between consecutive points increases, and when the operator moves slowly, the absolute interval between consecutive points decreases. That is, since the interval between consecutive points may vary depending on the operator, as described above, if it is determined whether the inclination of two consecutive points is within a predetermined range, the vertical or horizontal direction can be determined. It can be reliably determined whether or not the correction should be made as a straight line.
[0049]
Further, a predetermined constant value indicating the correction range may be changed by an operator. In this case, the operator designates a range to be corrected as a straight line in consideration of his / her habit at the time of handwriting input. This makes it possible to make optimal settings according to each operator.
[0050]
