BACKGROUND OF THE INVENTION
  The present invention provides an image processing apparatus that can be changed while visually observing characters displayed on a monitor.PlaceIn particular, the present invention relates to a recording medium suitable for editing characters on a stamp surface for making a stamp.
[0002]
[Prior art]
  A method for making a stamp by making the stamp surface while transmitting and shielding light with a positive document created based on the stamp surface data, and a method for making a stamp by making a stamp by controlling the heating means based on the stamp surface data The stamp producing apparatus of this type does not require special skills such as cutting the stamping surface manually, and thus has been highly evaluated by demanding customers who want to obtain various types of stamps easily and inexpensively.
[0003]
  In addition, when creating stamp data used in the stamp creation device, it is desirable that the stamp surface can be easily created in the same manner as when making the above-mentioned stamp surface. Therefore, a preview image of the stamp surface is displayed on the monitor of an information processing device such as a personal computer. Is displayed, and the font and layout of characters can be edited on the preview image by operating the mouse or keyboard. When the desired stamp is completed, a stamp is created based on the stamp data, and the used stamp data is stored, for example, when a stamp with the same name or name is needed. By reusing the stamp data, the stamp data can be created efficiently.
[0004]
[Problems to be solved by the invention]
  However, as in the conventional case, by simply reusing the stored stamp data, a stamp having the completely same stamp is repeatedly created. Has the problem that it cannot identify the owner or user of the stamp. This problem is particularly noticeable in the case of name stamps.
[0005]
  Therefore, when reusing the saved stamp data, the stamp data is displayed on the preview screen as original image data, and the font and layout of the characters are re-edited by operating the mouse or keyboard on the preview screen. A method is conceivable. However, since this method requires switching to the editing screen and various editing operations, it is not possible to efficiently create stamp data, and stamp data of slightly different characters with the same font and layout can be used. There is a problem that it is difficult to create.
[0006]
  Therefore, the present invention provides an image processing apparatus capable of easily creating a plurality of unique seal surface data from the same seal surface data (original image data).PlaceAnd a recording medium.

[0057]
  In the enlarged preview area 218, a rectangular identification frame 238 surrounding each character is displayed. The identification frame 238 is formed along the peripheral edge of the character cell of each character, and allows the operator to identify the character to be processed in the size adjustment field 234 and the position adjustment field 235. The identification frame 238 is switched between display and non-display each time the mouse pointer is positioned on the character cell of each character displayed in the enlarged preview area 218 and clicked.
[0058]
  Further, on the side of the enlarged preview area 218, a layout save button 236 for saving the state displayed in the enlarged preview area 218 and an initial state return button 237 for returning to the state immediately after the fine adjustment screen 233 is displayed. Is provided.
[0059]
  When the fine adjustment screen 233 is displayed, first, the identification frame 238 displayed in the enlarged preview area 218 is visually observed by the operator, and it is confirmed that the character surrounded by the identification frame 238 is a processing target. The When a character to be processed is specified, the mouse pointer is moved over the character in the enlarged preview area 218. If this character is surrounded by an identification frame 238, a non-processing target (identification) is detected by clicking the mouse. On the other hand, if it is not surrounded by the identification frame 238, it is switched to the processing target (display of the identification frame 238) by clicking the mouse.
[0060]
  When the character to be processed is specified as described above, the mouse pointer is moved to the size adjustment field 234 and the position adjustment field 235, and the buttons 234a to 234f and 235 are pressed. Then, fine adjustment is performed on a specific character surrounded by the identification frame 238. Thus, the operator can change the glyph size and position of the character while confirming the character to be processed by the identification frame 238, so that the layout has a desired balance with respect to the seal frame 223. Can be adjusted easily. Thereafter, when the adjusted layout state is saved as the original format, the adjusted stamp data is registered in the format selection field 212 for the original stamp in FIG. 6 when the layout save button 236 is pressed. . On the other hand, when the fine adjustment fails, the initial state return button 237 is pressed to return to the state immediately after the fine adjustment screen 233 is displayed.
[0061]
  When the adjustment is completed as described above, the completion button 214 is pressed to display the finely adjusted characters in the enlarged preview area 218 and the actual preview area 231 of the creation screen 230 as shown in FIG. . Then, when creating the stamp of the stamp face composed of these characters, the completion button 214 is pressed.
[0062]
  On the other hand, when it is desired to obtain a unique stamp surface by slightly changing the state of the stamp surface composed of the characters, the stamp processing button 241 is pressed. Further, when it is desired to obtain a unique stamp by slightly changing the previously created stamp, the stamp registered in the format selection field 212 for original stamp in FIG. After the data is read and displayed in the preview areas 218 and 231, the stamp processing button 241 is pressed.
[0063]
  When the stamp processing button 241 is pressed as described above, the stamp processing routine of FIG. 3 is executed. First, setting data indicating the change contents of the stamp is read (S1). Here, the setting data is composed of missing setting data, unengraved setting data, and composite content data. The setting data for chipping and the setting data for leaving an engraving are used to set conditions for a circular on-dot region for generating a chipping or leaving an engraving on the glyph 228 indicating the character itself or the seal frame 223. It has the number of occurrences of dot areas A · C, radii B · D, and data distribution. The data distribution specifies the ratio of mask image data to be generated with respect to the stamp surface. The entire command specifying that the mask image data is generated almost uniformly on the entire stamp surface and the character cell are concentrated. In-cell congestion command for designating generation of a specified portion, and designated partial congestion command for generating concentrated on a predetermined portion.
[0064]
  The composite content data designates a method of combining the original image data (print surface data) to be processed and the mask image data, and performs an AND operation on the original image data and the missing data that is the mask image data. Chipping synthesis processing to obtain changed image data, OR processing of original image data and unengraved data that is mask image data to calculate changed image data, and missing synthesis processing and unengraved synthesis processing It is possible to specify any one of the combination composition processing combining.
[0065]
  When the setting data is read out, it is determined whether or not the process designated by the composition content data is a missing composition process (S2). If it is a missing composition process (S2, YES), a missing data generation process is performed (S3), and the missing data generation routine of FIG. 4 is executed.
[0066]
  That is, as shown in FIG. 1, first, the first mask image buffer 245 formed as a missing data storage area is cleared (S21). The first mask image buffer 245 is set so that missing data can be formed so as to correspond to each dot in the data area, assuming that the stamp face data and the original image data are formed in a data area of 231 dots square. It consists of a two-dimensional coordinate data table consisting of X and Y coordinates.
[0067]
  Next, for example, 20 is read as the number of occurrences A of the on-dot regions 242 (S22), and for example, 6 dots are read as the radius B of the on-dot regions 242 (S23). Then, random numbers are generated in the range of 0 to 230 of the X coordinate (S24), and random numbers are generated in the range of 0 to 230 of the Y coordinate (S25), and then the first mask image buffer specified by these random numbers. A circular on-dot region 242 having a radius B of 6 dots is written at the coordinate position (X, Y) of 245 (S26).
[0068]
  Thereafter, after “1” is subtracted from the occurrence number A (S27), it is determined whether the occurrence number A is “0” (S28). If the occurrence number A is not “0” (S28). , NO), the on-dot region 242 is written at the coordinate position (X, Y) of the first mask image buffer 245 specified by the next random number by being re-executed from S24 described above. Then, when the processes of S24 to S28 are repeatedly executed, the on-dot region 242 is sequentially written in an arbitrary place and the occurrence number A becomes “0” (YES in S28). Writing to the on-dot area 242 is completed. Thereafter, the random image data in the first mask image buffer 245 including, for example, the 20 on-dot regions 242 is inverted to become missing data that is mask image data including the off-dot regions 242 ′ (S29). ), The process returns to the stamping process routine of FIG.
[0069]
  When missing data (mask image data) including the on-dot area 242 reversed as described above is generated (S3), the stamp face data displayed in the preview areas 218 and 231 of the creation screen 230 in FIG. After being stored in the original image buffer 247 as image data, the original image data and the above-described missing data are subjected to a logical product operation. Then, the modified image data in which the missing portions 223a and 228a are generated in the glyph 228 and the seal frame 223 is generated. Thereafter, as shown in FIG. 10, the changed image data is displayed as new seal face data in the preview areas 218 and 231 of the creation screen 230 (S13), and this routine is terminated.
[0070]
  On the other hand, if it is determined in S2 of FIG. 3 that the composite content data is not a missing composite process (S2, NO), it is subsequently determined whether the process specified by the composite content data is an unengraved composite process. (S5). If it is the uncarved synthesis process (S5, YES), the uncarved data generation process is performed (S6), and the uncarved data generation routine of FIG. 5 is executed.
[0071]
  That is, as shown in FIG. 2, the second mask image buffer 246 formed as a storage area for unengraved data is cleared (S31). If the stamp face data and the original image data are formed in a data area of 231 dots square, the second mask image buffer 246 is set so that unengraved data can be formed so as to correspond to each dot in the data area. It consists of a two-dimensional coordinate data table consisting of the X and Y coordinates.
[0072]
  Next, for example, 20 is read as the number C of occurrences of the on-dot regions 244 (S32), and 3 dots are read as the radius D of the on-dot regions 244 (S33). Then, random numbers are generated in the range of 0 to 230 of the X coordinate (S34), and random numbers are generated in the range of 0 to 230 of the Y coordinate (S35), and then the coordinate position (X, Y) is compared with the original image data composed of the seal face data displayed in the preview areas 218 and 231 of the creation screen 230 in FIG. 8, so that the coordinate position (X, Y) of the original image data is obtained. It is determined whether “1”, which is an on dot, is set (S36).
[0073]
  When “1” is not set in the coordinate position (X, Y) of the original image data (S36, NO), it is determined that the seal frame 223 and the glyph 228 do not exist at the coordinate position (X, Y). The coordinate position (X, Y) is specified by generation of a new random number by re-execution from S34 so as not to generate an independent engraving in a portion away from the seal frame 223 or the glyph 228. In S36, the same determination as described above is performed. If “1” is set in the coordinate position (X, Y) of the original image data (S36, YES), the second mask image buffer is set. A circular on-dot region 244 having a radius D of 3 dots is written at the coordinate position (X, Y) of 246 (S37).
[0074]
  Thereafter, after “1” is subtracted from the number of occurrences C (S38), it is determined whether or not the number of occurrences C is “0” (S39), and the number of occurrences C is not “0” (S39). , NO), the on-dot region 244 is written at the coordinate position (X, Y) of the second mask image buffer 246 specified by the new random number by performing again from the above-described S34. Then, when the processes of S34 to S39 are repeatedly executed, the on-dot area 244 is sequentially written in an arbitrary place, and when the number of occurrences C becomes “0” (S39, YES), Writing to the on-dot area 244 is completed. Thereafter, the random image data in the second mask image buffer 246 is set as unengraved data which is mask image data, and then the routine returns to the stamp processing routine of FIG.
[0075]
  When the unengraved data (mask image data) including the on-dot region 244 is generated as described above (S6), the original image data and the unengraved data are logically ORed to obtain the glyph 228 and the seal frame. Changed image data in which uncarved portions 223b and 228b protruding from 223 are generated. Then, as shown in FIG. 11, the changed image data is displayed as new stamp data in the preview areas 218 and 231 of the creation screen 230 (S13), and this routine ends.
[0076]
  If it is determined in S5 of FIG. 3 that the composite content data is not an unengraved composite process (S5, NO), then it is determined whether or not the process specified by the composite content data is a combination composite process. (S8). In the case of the combination synthesis process (S8, YES), missing data is generated by the above-described missing data generation process (S9), and unengraved data is generated by the unengraved data generation process (S10). Thereafter, the original image data and the missing data are subjected to a logical product operation to generate the changed image data having the missing portions 223a and 228a in FIG. 1 (S11). By performing a logical OR operation with the remaining data, modified image data having uncarved portions 223b and 228b in FIG. 2 is generated (S12). The changed image data having the missing portions 223a and 228a in FIG. 1 and the unengraved portions 223b and 228b in FIG. 2 are displayed as new seal face data in the preview areas 218 and 231 on the creation screen 230 (S13). The routine is terminated. On the other hand, if it is not the combination synthesis process (S8, NO), the original image data is not changed to the changed image data without performing any of the missing data generation process and the unengraved data generation process on the original image data. Is done. Then, it is displayed as seal data in the preview areas 218 and 231 of the creation screen 230 (S13), and this routine is terminated.
[0077]
  As a result of executing the stamping process as described above, as shown in FIGS. 10 and 11, when the stamped face having the missing portions 223 a and 228 a and the uncarved portions 223 b and 228 b is displayed in the preview areas 218 and 231. By visually observing this display, the operator can confirm the change state of the stamp face. If the change state of the stamp surface is satisfactory, the stamp on the stamp surface is created by pressing the completion button 214. On the other hand, if the change state of the stamp is not satisfactory, the stamp processing button 241 is pressed again, and the stamp is processed by the stamp processing based on the original image data of the original image buffer 247 including the stamp data before the stamp processing in FIG. Changes are newly made. Furthermore, when finely adjusting the changed stamp face, the fine adjustment button 232 is pressed, and the size and position of the character are adjusted.
[0078]
  Note that the setting data used for the stamping process can be changed by pressing a button (not shown) or when the stamping process button 241 is repeatedly pressed over a predetermined number of times, the number of occurrences A · C and radius B in the setting data. D, performed by displaying a window that can change the content of the composite content data in a window.
