Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a warning device for a traffic signal.

[0002]

2. Description of the Related Art Traffic signals are installed for the purpose of controlling the flow of vehicles and people and preventing traffic accidents. Means of deterring pedestrians from crossing the pedestrian crossing with the red light signal were verbal caution, educational guidance at educational institutions such as schools, and cautionary recommendations to the extent that signboards were installed near traffic lights.

[0003] Japanese Patent Application Laid-Open No. 6-162391 discloses a system in which a display is installed near a traffic light and an advertisement is displayed in association with the display color of the traffic light.

[0004]

Therefore, the only way to prevent the crossing at the time of the red light is to rely on the morals of the pedestrian itself.

According to the present invention, a display is installed in the vicinity of a traffic light, an advertisement is usually displayed, and when a pedestrian crossing at the time of a red light is detected, an image of the pedestrian is displayed on the display. An object of the present invention is to provide a warning device for a traffic light.

[0006]

According to the present invention, there is provided a signal data receiving section for receiving instruction data of a traffic light, an advertisement data storage section for storing image data of an advertisement, and an image for receiving an image in a crosswalk to be monitored. A data receiving unit, and normally transmits the image data of the advertisement to a display installed near the traffic light, and based on the image in the pedestrian crossing, the traffic light of the pedestrian crossing entered the pedestrian crossing when displaying red. A processing unit for transmitting an image of the offender to the display when the offender is detected. With this configuration, the offender can avoid attracting the attention of other pedestrians, which leads to refraining from crossing the red light, thereby preventing the pedestrian from crossing at the time of the red light.

Further, according to the present invention, an image of the violator is enlarged and displayed for a violator who continues to cross among the violators.
By virtue of this configuration, if the offender crosses the crosswalk ignoring the red light, the image is enlarged and attracts the attention of other pedestrians. It is possible to prevent a pedestrian from crossing at the time of a red light because it is not necessary to cross the road.

Further, the present invention has a violation case storage unit for storing the image of the violator, and the processing unit further stores the image of the violator in the violation case storage unit. The image data of the advertisement is displayed on a display, and the image of the offender is displayed. With this configuration, violators will not only be displayed when they violate, but will continue to be displayed in the future, so they will hesitate to cross, and as a result, they will refrain from crossing the red light, It is possible to prevent pedestrians from crossing at the time.

[0009]

FIG. 1 shows a system configuration diagram. The camera 12 captures an image of the detection range in the pedestrian crossing and transmits the image to the processing device 11. The traffic light 13 transmits information of the color currently displayed on the traffic light to the processing device 11. The display 14 receives and displays output image data from the processing device 11. Upon receiving the offender image data from the processing device 11, the violation case database 15 stores the image data. The advertisement database 16 stores the image data of the advertisement for which the advertisement display request has been made, on a CD-ROM, MO,
It is stored for each advertisement record via a storage medium such as a VD, and is displayed at the time of normal display described later. Data storage unit 1
Reference numeral 7 stores data and parameters used in each process described below based on the process of the processing device 11.

The offender detection program 101 detects an offender who crosses a pedestrian crossing when the pedestrian crossing-like signal is in a red state, and performs registration processing in the current offender table 130. The violation status determination program 102 determines the state of the current offender. Specifically, it is determined whether the user has begun to cross the pedestrian crossing, has crossed, or has turned back halfway. The image processing program 103 is displayed on the display 1
4 to select and output an image to be output.

FIG. 2 shows an example of installation of the camera 12 and the display 14. The camera 12 is installed near the traffic signal 13 and at a position where images in a range including both ends of the crosswalk 18 can be acquired. The display 14 is installed at a position where pedestrians waiting for a traffic light on each other's sidewalk 19 can easily see them, such as above the traffic signal 13. In the present embodiment, the cameras 12 and the display 14 are installed one by one near each traffic light 13. Thereby, of the two cameras 12,
Either camera 12 captures the front of the offender and the other camera 12 captures the rear of the offender. Similarly, one of the two displays 14 displays an image of the front of the offender, and the other displays an image of the back of the offender.

Here, a pedestrian who enters the pedestrian crossing 18 when the pedestrian traffic light is at a red light is defined as a violator 24. At the time of red traffic light, the traffic light for pedestrians indicates the state of red display,
A green signal indicates that a pedestrian traffic light is displayed in blue.

FIG. 3 shows a photographing range of the camera 12. The camera 12 captures an image of a violator detection range 23 indicated by a broken line, and the processing device 11 detects a violator 24 crossing the crosswalk 18. The position of the offender 24 is determined in two-dimensional coordinates indicated by a road direction 22 which is a direction parallel to the road and a cross direction 21 which is a direction parallel to the pedestrian crossing within the offender detection range 23. The location is specified by the coordinate position from the origin.

FIG. 15 is a conceptual diagram showing switching of the display on the display 14 depending on the state.

The normal display is a case where there is no offender with a green light or a red light. After displaying one record of the image of the advertisement in the advertisement database 16, the violation case database 15 is displayed.
One record of the violation case image is displayed, and next, one record of the advertisement image of the advertisement database 16 with the record number incremented is displayed, such that the advertisement image of the advertisement database 16 and the violation case image of the violation case database 15 are displayed. Are alternately displayed, and the respective image records are incremented and sequentially displayed on the display 14.

The offender display is a case where there is an offender with a red light, and the offender 24 is displayed on the display 14. When switching from normal display to offender display, normal display and offender display are detected when a violator is detected at the time of red light, and when switching from offender display to normal display, a green light is displayed, or At the time of the red light, the offender is not on the crosswalk.

FIG. 16 shows a flowchart for switching the display on the display 14. This flowchart continues to operate while the processing device 11 is operating.

In step S1601, the image processing program 103 is executed.
Displays the normal display of the advertisement image and the past violation case image on the display 14. In step S1602, the image processing program 103 determines whether the signal is a red light. In the case of a red light, the image processing program 103 determines whether the offender 24 has been detected in S1603.

In step S1603, the image processing program 103
When the offender 24 is detected, the offender is displayed in S1604, and the process returns to the signal check process in S1602.
When switching from the red signal to the green signal, the image processing program 103 clears the state of various parameters even if the offender is being displayed in S1604, and returns from the processing in S1602 to the normal display processing in S1601.

In the case of a green signal in step S1602, the image processing program 103 returns to step S1601 to continue normal display. Similarly, the image processing program 103 executes S160
Also in the case where the offender 24 is not detected in 3, the process returns to S1601 and the normal display is performed.

Here, FIGS. 6 to 12 show detailed flowcharts of the processing for detecting the offender 24 and displaying the offender 24 in S1603 and S1604. In the following description, the processing device 11 performs processing on an image captured by one camera 12 in FIG. 2. However, the processing device 11 performs the same processing on an image captured by the other camera 12. Shall be performed.

In FIG. 6, the current offender detection range 23 is shown.
The process for detecting the offender in the above will be described. START is started from a state in which a red light is generated. The processing device 11
The violator detection program 101 is activated, and the violator 24 is detected with respect to the image captured from the camera 12.

In S601, the offender detecting program 10
1 initializes a current offender table 130 of the data storage unit 17 that stores the offender 24 of the current image data received from the camera 12.

FIG. 13 shows the structure of the current offender table 130. The current offender table 130 is a table for storing the offenders 24 detected in the current image, and each data is used for comparison with a past offender image described later. The current offender table 130 includes current ID number data 131 for identifying the offender 24 in the image, current coordinate data 132 indicating the coordinates where the offender 24 in the image is located in the offender detection range 23, and violations in the image. Current RGB value data 133 indicating the color information of the offender 24 and current range data 134 indicating the size of the outline of the offender 24 in the image.

In S602, the offender detecting program 10
1 receives the current image data from the camera 12.

In S603, the offender detecting program 10
1 is a violator 2 serving as a criterion for determining whether or not a violator 24 is presently inside the pedestrian crossing 18 in the image data.
The background image data stored in advance in the data storage unit 17 is called as the image data of only the background where no 4 exists.

In S604, the offender detecting program 10
1 compares the background image data with the current image data.
FIG. 4 is a conceptual diagram showing a method of determining whether a violator 24 has been detected or not. By storing the image as shown in FIG. 4A from the camera 12 in advance in the data storage unit 17 as background image data without the offender 24, the offender 24 is compared with the background image data. Not detected. In FIG. 4B, the offender 24 is detected, and the position of the offender 24 is detected as the offender coordinates 28 in the offender detection coordinate system 27. Violator coordinates 2
8 specifies the positions in the road direction 22 and the cross direction 21 by using the coordinate system shown in FIG. 3 and the positions from the origin in FIGS. 4A and 4B.

In step S605, the offender detecting program 101
Determines from the comparison result whether the offender 24 is present in the current image data.

The offender detecting program 101 detects the offender 2
4 is detected, in order to add a current offender record, the current offender table 130 of the offender 24 is added in S606.
Of the current ID number 131 is added. Here, when a car passes through the offender detection range 23, the offender detection program 101 sets the range data 134 having an area area larger than a predetermined area determined to be a pedestrian so as not to detect the car. In this case, it is determined that the vehicle is a vehicle, and is not added to the offender record.

In step S607, the offender detecting program 101
Are the current coordinate data 132 as the center coordinates of the range where the current offender 24 is detected, the RGB value data 133 as the color data of the range where the current offender 24 is detected, and the current offender 24.
The range data 134 is acquired as the size of the range in which is detected, and registered in the current offender table 130 in S608.
And the data is stored in the data storage unit 17.

In S609, the offender detecting program 10
1 is the current offender table 130 for all 24 offenders
It is confirmed whether or not registration has been performed. If registration has not been completed, the process returns to S606, and registration processing is performed for the next offender 24.

If the comparison has been completed on all the screens in S609 or if the offender 24 is not present in the current image data in S605, the comparison check processing with the continuous offender table 140 shown in FIG. 7 is continued.

From the comparison check processing with the continuation violator table 140 shown in FIG. In the flowchart of FIG.
It is determined whether or not the current offender is a continuous offender who continuously crosses the red light in the offender table 130, and if the current offender does not match the ongoing offender, it is registered as a new offender and a match is made. If so, a series of processes for determining whether or not the user continues to cross the pedestrian crossing and determining whether or not the image is to be enlarged when displayed on the display 14 will be described.

FIG. 13 shows the structure of the current offender table 130. The current offender table 130 is a table for storing the offenders 24 detected in the current image, and each data is used for comparison with a past offender image described later. The current offender table 130 includes current ID number data 131 for identifying the offender 24 in the image, current coordinate data 132 indicating the coordinates where the offender 24 in the image is located in the offender detection range 23, and violations in the image. Current RGB value data 133 indicating the color information of the offender 24 and current range data 134 indicating the size of the outline of the offender 24 in the image.

FIG. 14 shows a configuration example of the continuation offender table 140. The continuation violator table 140 is a table stored for the violators 24 detected at the time of the previous image reception. The continuation violator table 140 compares the continuation violator data with the individual violator data, which identifies the continuation violator. The continuation comparison check 142 indicating the result status, the continuation coordinate data 143 indicating the coordinates where the continuation violator is located within the violator detection range 23, the continuation RGB value data 144 indicating the color information of the continuation violator data, and the continuation violator. When the continuation violator 145 indicating the size of the contour, the traversal start side coordinate data 146 indicating the coordinates when the continuation violator is detected in the violator detection range 23 for the first time in the past, and the continuation violator are output to the display 14. Is composed of enlarged data 147 indicating whether or not to enlarge.

The continuation comparison check 142 is in the “unchecked” state in which the corresponding continuation offender data is not checked, the “continuation” state in which the continuation offender data is continuously stored in the continuation offender table, and the continuation offender. The data has three types of states, "matched", in which it is determined that the offender data currently matches. The continuation coordinate data 143, the continuation RGB value data 144, and the continuation range data 145 are also used for comparison with the current offender table 130. If the continuation violator record corresponding to the enlargement data 147 is an enlargement target, “yes” is set, and if it is not an enlargement target, “no” is set.

In S701, the violation status determination program 1
02 is “not checked” in the continuation comparison check 142 for all continuation offender records in the continuation offender table 140
State.

In S702, the violation status determination program 1
02 initializes a record number [r] for sequentially calling the current offender records in the current offender table 130. S
At 703, the violation status determination program 102 calls the current offender record corresponding to the record number [r].

At S704, the violation status determination program 1
02 initializes a record number [j] for sequentially calling continuation offender records stored in the continuation offender table 140.

In S705, the violation status determination program 1
02 calls the continuation offender record corresponding to the record number [j].

In some cases, the continuation violator table 140 has no continuation violator record. In step S706, the violation status determination program 102 determines whether all continuation violator records in the continuation violator table 140 have been completed.

If it is determined in S706 that there is a continuing violator record, a comparison process between the continuing violator record and the current violator record is performed in S708. FIG. 10 shows a flowchart of the comparison process between the continuing offender record and the current offender record in S708. In FIG. 10, the continual offender record is compared with the current offender record, and it is determined from the position, color, and size whether the offender is the same person.

The continuation violator record in which the continuation violator record already matches the current violator record has the item of the continuation comparison check 142 in the “continuation” state. In that case, the subsequent comparison processing is not performed and the process is terminated. However, the non-matching continuation violator record is in the "unchecked" state,
Perform the following comparison check. Specifically, the violation status determination program 102 executes the continuous comparison check 1 in S1001.
It is determined whether the item 42 is in the “continuation” state. If the continuation comparison check 142 is in the “continuation” state, it is determined that the continuation comparison check is not a target of the comparison processing, and the subsequent comparison check is not performed.
In the case of the “unchecked” state, it is determined to be a comparison processing target, and the next comparison check is performed.

Next, when the displacement of the position in the current offender record from the position of the continuous offender record is larger than the moving speed of the pedestrian, it can be determined that the offender is a different offender. A reference distance serving as such a criterion is determined in advance, and the determination is made based on the reference distance. If the determination result is larger than the reference distance, it is determined that the violators are different, and the comparison process is not performed thereafter, and the process is terminated. . Specifically, the violation status determination program 102
At 1002, the continuous coordinate data 143 and the current coordinate data 13
2. If the distance is smaller than the reference distance, it is determined that there is a possibility that the continuous offender record and the current offender record are the same offender, and the check in S1003 is further performed.

Next, it is determined whether or not the violators are the same based on the RGB value data in the violator's image. When the difference between the RGB value data is large, it is determined that the violator is different, and the RGB value data is different.
If the difference between the value data is small, it is determined that there is a possibility of the same offender. In the case of violators who may be the same violator, the following comparison check is further performed, and if it is determined that they are different violators, the process ends. Specifically, the violation status determination program 102 calculates the difference between the continuous RGB value data 144 and the current RGB value data 133 in S1003,
If the difference between the GB values is within a predetermined range, it is determined that the continuous violator record and the current violator record have the same color and may be the same violator, and further check is performed.

Finally, based on the offender's range data, a fixed value is determined as a criterion for determining whether or not the offender has a similar size. The violation status determination program 102
At 1004, the continuous range data 145 and the current range data 13
4 and if the difference result is within a predetermined value, it is determined that the continuous violator data and the current violator data are the same violator, and in S1005, the continuous violator record continuation comparison check 142 To the "Match" state.
If the difference result is equal to or more than a certain value, it is determined that the violator is different and the process is terminated. When the comparison processing is completed, the processing after S709 is continuously performed.

In S709, the violation status determination program 1
02 is the result of the comparison processing in S708, and the continuous comparison check 1
It is determined whether or not 42 is in the "match" state. If the continuation comparison check 142 is not in the “matched” state, it is determined that the continuation violator record currently being called does not match the current violator record, the record number is incremented in S710, and the process proceeds to S705. Returning, the same processing is performed for the next continuation offender record. If the continuation comparison check 142 is “match”, the violation status determination program 102 performs the continuation violator direction check determination processing in S711.

FIG. 9 is a flow chart of the direction check judging process of the continual offender, which will be described in detail. In FIG. 9, it is determined whether the offender is trying to continue crossing the pedestrian crossing or quitting and trying to turn back. For the offender who continues to cross, the screen is enlarged and output when the display is output later. A flag is set to output a flag that does not expand to the offender who returns.

In S901, the violation status determination program 1
02 updates the continuation violator data's continuation comparison check 142 from the "match" state to the "continuation" state.

The outline of S902 is to specify the current offender coordinate position in the offender detection coordinate system for the sidewalk where the offender started crossing in the crossing direction 21. FIG. 5 shows the positional relationship between the offender 24 and the sidewalk on the crossing start side. In FIG. 5A and FIG. 5B, the cross direction coordinate value of the current offender position 26 is equal to or larger than the cross direction coordinate value of the sidewalk 192 on the crossing start side, and the sidewalk on which the offender 24 starts crossing is the sidewalk 1
It can be determined that it is 92. In FIGS. 5C and 5D, the cross direction coordinate value of the current offender position 26 is equal to or smaller than the cross direction coordinate value of the sidewalk 191 on the crossing start side, and it is determined that the sidewalk on which the offender 24 started crossing is the sidewalk 191. . Violator 2 from above
It is possible to determine from which sidewalk 4 has started crossing.

At S902, the violation status determination program 1
02 is the current coordinate data 1 of the current offender table 130
32 and the traversal start side coordinate data 146 of the continuation offender table 140, a difference is made for the coordinate component in the traverse direction 21.
If the value is equal to or greater than 46, the state is determined as shown in FIGS.
03, and if the current coordinate data 132 value is smaller than the crossing start side coordinate data 146 value, the state is determined as shown in FIGS. 5C and 5D, and the flow shifts to S904.

The outline of S903 is to determine whether the violator 24 is the enlargement target in FIG. 5A or the non-enlargement target FIG. 5B in FIGS. 5A and 5B. 5A and 5B, the past offender position 25, that is, the continuation coordinate data 143 of the continuation offender table 140, and the current offender position 2
6, that is, the current coordinate data 132 of the current offender table 130 is compared with the coordinate component in the transverse direction. If the current coordinate data 132 is equal to or greater than the continuous coordinate data 143,
Since the pedestrian is a pedestrian who continues to cross over the crossing start sidewalk 192 ignoring the signal, the pedestrian is determined to be an enlargement target as shown in FIG. 5A. The current coordinate data 132 is the continuous coordinate data 143
If it is smaller, it is a pedestrian trying to turn back to the pedestrian crossing sidewalk 192, so that it is determined that the pedestrian is not to be enlarged as shown in FIG. 5B.

In S902, the violation status determination program 1
02 is the current coordinate data 132 and the continuation coordinate data 143
Is taken for the coordinate component in the transverse direction, and if the current coordinate data 132 value is equal to or greater than the continuous coordinate data 143 value,
In S905, the enlarged data 14 of the continuation offender table 140
7 is set to “yes”, and if the current coordinate data 132 value is smaller than the continuation coordinate data 143 value, the enlarged data 147 of the continuation offender table 140 is set to “no” in S906, and the process proceeds to S907.

The outline of S904 is to determine whether the offender 24 is the enlargement target in FIG. 5C or FIG. 5D, and is not the enlargement target in FIG. 5D. 5C and 5D, the past offender position 25, that is, the continuation coordinate data 143 of the continuous offender table 140, and the current offender position 2
6, that is, the current coordinate data 132 of the current offender table 130 is compared with the coordinate component in the transverse direction, and if the current coordinate data 132 is smaller than the continuous coordinate data 143, the pedestrian pedestrian 191 ignores the signal from the sidewalk 191 and continues walking. Therefore, as shown in FIG. Current coordinate data 132 is continuous coordinate data 1
In the case of 43 or more, it is a pedestrian who tries to turn back to the sidewalk 191 on the crossing start side, and therefore it is determined that the pedestrian is not an enlargement target as shown in FIG.

In S904, the violation status determination program 1
02 is the current coordinate data 132 and the continuation coordinate data 143
Is taken for the coordinate component in the transverse direction, and if the current coordinate data 132 value is equal to or greater than the continuous coordinate data 143 value,
In S906, the expanded data 14 in the continuation violator table 140
7 is set to “no”, and if the current coordinate data 132 value is smaller than the continuation coordinate data 143 value, the enlarged data 147 of the continuation offender table 140 is set to “yes” in S905, and the process proceeds to S907.

In S907, the violation status determination program 1
02 is the current offender record of the current offender table 130, the current coordinate data 132, the current RGB value data 13
3. The current range data 134 is updated to the continuation coordinate data 143, the continuation RGB value data 144, and the continuation range data 145 corresponding to the continuation offender record of the continuation offender table 140, and the process from S712 is continuously performed.

In S706, the continuation violator record is completed at the end when the target violator record and the continuation violator record are compared but no matching record is detected. In this case, the current offender record is determined to be a new offender 24, and a new offender data registration process of S707 is performed.

FIG. 8 shows a flowchart of the new offender registration process.

The violation status determination program 102 executes S80
In step 1, a new continuation offender record area is created in the continuation offender table 140. In step S802, the continuation ID number information 141 is added. In step S803, the comparison check between the current offender table 130 and the continuation offender table 140 is completed. Is set to “continue”,
In S804, the current coordinate data 132 of the current offender data,
Based on the current RGB data 133 and the current range data 134, it is stored in the continual offender record of the continual offender table 140, and the image data of the offender is stored.

In step S805, the current coordinate data 132 of the current offender data is the position where the offender 24 is detected in the offender detection range 23 for the first time, and the position is on the side where the crossing was started. 132 is stored in the crossing start side coordinate data 146. In S806, the enlarged information 1
47 is set to “Yes” and the continuation violator table 140 is set.
And the processing after S711 is continuously performed.

The violation status determination program 102 executes S70
7 after performing the new offender registration process and the continuous offender direction checking process in S711, in S712, it is determined whether all the current offender records in the current offender table 130 have been completed, that is, the current camera 12 It is determined whether or not the check has been completed for all the images of the offenders 24 detected when the captured image has been captured, and if not all have been completed, the current offender record number [r] is incremented in S713. Then, the process is performed again from the current offender record calling process of S703. If all of the offender records have been completed, the process proceeds to the continuous offender table 140 image storage process of FIG.

FIG. 11 is a flowchart showing an image storing process for all continuation offender records in the continuation offender table 140. In the flowchart of FIG.
When the offender 24 is on the pedestrian crossing, the number of divisions for outputting the images of all the offenders to the display 14 is counted, and the offender who has been up to immediately before but no longer exists in the current image is crossed. Is determined, and if so, a process of storing the image data in the violation case database 15 as image data to be output as a past violation case is performed.

The violation status determination program 102 executes S11
In step S110, a screen division variable "p" for dividing the screen of the display 14 by the number of offenders 24 is initialized.
In step 2, the record number "j" for calling the continuation offender record of the continuation offender table 140 is initialized.

In S1103, the violation status judging program 102 calls the continuation violator record corresponding to the record number [j].

In step S1104, the violation status determination program 102 determines whether or not the continuation violator table 140 has finished calling all of the continuation violation records. If all of the calls have been completed, the violator image output process shown in FIG. 12 is performed. . If the processing has not been completed, the violation status determination program 102 checks the continuous comparison check 142 in S1105 if there is continuous violator data.

In the state where the offender continues to cross the pedestrian crossing in S1105, that is, in the state where the continuation comparison check 142 is “continuation”, the violation situation determination program 102
In 1109, the screen division variable “p” for displaying the offender 24 on the display 14 is incremented. S1105
When the continuous comparison check 142 is in the "unchecked" state,
This indicates that the violator of the corresponding continuing violator record does not exist in the currently captured image data. The violation status determination program 102 checks the status of the violation status determination program 10 in S1106 to confirm the status of the offender who has left the crosswalk.
2 is to calculate the moving distance from the crossing start position to the immediately preceding offender's position from the absolute value of the difference between the crossing direction coordinate component of the continuation coordinate data 143 and the crossing direction coordinate component of the crossing start side coordinate 146, Is compared with half the distance of the pedestrian crossing. If the moving distance is equal to or greater than the intermediate distance of the pedestrian crossing, it is determined that the offender 24 has ignored the red light and has crossed the sidewalk on the opposite side. The image data of the offender is stored in the database 15. If the moving distance is shorter than the intermediate distance of the pedestrian crossing, the offender 24 determines that the offender 24 has turned back to the side of the sidewalk where he or she has begun to cross, and does not save the image data.

The violation status determination program 102 executes S11
At 08, the perpetual offender data is deleted, and S1110
Then, the record number is incremented, and the process returns to S1103.

FIG. 12 shows a flowchart of the offender image output processing. The processing device 11 is an image processing program 103
Is started, it is determined whether or not each violator record is a target for enlargement, the display 14 is divided, and processing for outputting all the individual violators is performed.

The image processing program 103 is executed in step S1201.
, The display screen of the display 14 is divided by the screen division variable “p”, and the display arrangement variable “Q” is initialized to insert the violator 24 into each of the divided frames of the display 14 in S1202. The record number “j” for calling the continuation offender record of the party table 140 is initialized.

The image processing program 103 executes S1204
To call the continuation offender record corresponding to the record number "j", determine in S1205 whether all continuation offender records in the continuation offender table 140 have been completed, and if there are continuation offender records, continue in S1206. It is checked whether or not the enlarged data 146 is set to “yes”. If “yes”, the image processing program 103 performs an enlargement process in S1207. FIG. 17 shows an example of display output when there are three violators 24 within the violator detection range 23. In FIG. 17, violators A and B are targets of enlargement, and the image is enlarged. Violator C is not to be enlarged, and is displayed as not enlarged.
In step S1208, the image processing program 103 sets the offender 24
Is stored. In S1209, the image of the offender 24 is arranged at a position corresponding to the display arrangement variable “Q”.

The image processing program 103 executes S1210
Increments the display arrangement variable “Q” by S
In step 1211, the continuation violation record number “j” is incremented, and the processing from S 1203 is repeated until all records in the continuation violator table 140 are completed.

In step S1205, the image processing program 103
If all records in the continuation violator table 140 have been completed, the processing becomes end and a series of operations is completed, and the process returns to S601 in FIG.
