  However, the first to third techniques have the following problems. That is, in the first to second prior arts, it is difficult to predict the timing at which the user visually recognizes the displayed character or line, so the character or line is at least from the user's conscious perception limit value. It is necessary to display in a high range.

  For this reason, when the user already knows which area the displayed vehicle surrounding information corresponds to, there is a problem that the displayed character or line can be annoying.

  In addition, the user needs to visually recognize the character or line every time the display of the vehicle periphery information is switched in order to grasp which region the displayed vehicle periphery information corresponds to. For this reason, since it takes time and effort for the user to view, there is a problem that it takes time and effort to grasp the situation around the vehicle.

In the third prior art, a plurality of vehicle peripheral information is simultaneously displayed as composite image information. Therefore, it is troublesome for the user to find out the vehicle peripheral information that needs to be visually recognized from the composite image information. It takes. Moreover, since it is necessary to make the image size of each vehicle periphery information small with respect to the screen size of a monitor, it is not easy for a user to visually recognize vehicle periphery information. Therefore, there is a problem for the user that it takes time to grasp the situation around the vehicle.
The present invention has been made to solve such a conventional problem, and the main purpose of the present invention is that the user does not feel bothersome and the user can understand the situation around the moving body. It is an object of the present invention to provide a moving object peripheral display device that can be easily grasped.

  In order to achieve the above object, the invention described in the claims of the present application is acquired by an imaging unit that captures an image of an area around a moving body and acquires peripheral image information indicating the state of the area, and the imaging unit. Shooting information selection means for acquiring selected shooting information indicating the status of a predetermined area from the surrounding shooting information, and a peripheral for specifying an area corresponding to the selected shooting information acquired by the shooting information selection means The data generation means for generating the part specifying information and the selected photographing information acquired by the photographing information selecting means are displayed, and the peripheral part specifying information generated by the data generating means is lower than the conscious perception limit value, And a display means for displaying within the range of unconscious perception.

  In the invention described in the claims of the present application, the content of the peripheral portion specifying information (corresponding to the conventional lines and characters), that is, the region to which the selected photographing information to be displayed corresponds corresponds to the use Can potentially communicate to others.

  For this reason, the user can potentially determine which area of the peripheral area specific information corresponds to the content of the peripheral area specific information, i.e., the selected shooting information to be displayed, without annoying the peripheral area specific information. I can grasp it. Therefore, the user can easily grasp the situation of the area as compared with the conventional case, and can easily grasp the situation around the moving body as compared with the conventional case.

  In addition, since the user does not need to consciously understand the contents of the peripheral part specifying information even when the selected photographing information displayed is switched, the situation around the moving body is also compared with the conventional case. Can be easily grasped.

  In addition, since it is not necessary to make the selected photographing information smaller than the screen size of the display means, the situation around the moving body can be easily grasped in this respect as well.

  In step S150, the display control unit 5 causes the in-vehicle display device 6 to display the selected shooting information provided from the shooting information selection unit 3.

  Next, in step S160, the display control unit 5 sets the intermittent time and the display time based on the vehicle information given from the vehicle information output device 2 to the perceptual limit value for the intermittent time and the display time. Set to be within the range of low, unconscious perception.

  Next, in step S170, the display control unit 5 causes the in-vehicle display device 6 to display the selected shooting information given from the shooting information selection unit 3, while the peripheral part specifying information given from the data generation unit 4 is displayed. The in-vehicle display device 6 displays the set display time for each set intermittent time. Thereafter, the mobile object peripheral display device 1 returns to step S110. In addition, when the mobile peripheral display device 1 repeats this processing, when the data generation unit 4 outputs the same peripheral portion specifying information to the display control unit 5, the display control unit 5 performs the following processing.

  That is, in step S160, the display control unit 5 sets the display time by the above-described process, while the peripheral part specifying information is first displayed on the in-vehicle display device 6 and the time until the present time, Set to increase the intermittent time.

  As described above, in the present embodiment, the mobile object peripheral display device 1 displays the selected photographing information acquired by the photographing information selection unit 3, and the peripheral part specifying information is lower than the conscious perception limit value. Display within the range of unconscious perception.

  Therefore, the mobile object peripheral display device 1 allows the user to visually recognize the content of the peripheral part specifying information (corresponding to conventional lines and characters), that is, to which area the selected photographing information to be displayed corresponds. Can potentially communicate to.

  For this reason, the user can grasp | ascertain potentially the area | region which the content of peripheral part specific information, ie, the selected imaging | photography information displayed, corresponds, without feeling troublesome peripheral part specific information. Therefore, the user can easily grasp the situation in the area as compared with the conventional case, and can easily grasp the situation around the vehicle 100 as compared with the conventional case.

  In addition, since the user does not need to consciously understand the content of the peripheral portion specifying information even when the selected shooting information to be displayed is switched, the situation around the vehicle 100 can be compared with that in the past. Can be easily grasped.

  In addition, since it is not necessary for the selected shooting information to be smaller than the screen size of the in-vehicle display device 6, the user can easily grasp the situation around the vehicle 100 in this respect as compared with the conventional case. .

  Further, as shown in FIGS. 3 to 6, the peripheral portion specifying information is a plane that shows the position of the region corresponding to the selected shooting information acquired by the shooting information selection unit 3 and the position of the vehicle 100 in a plan view. Image information 40 is included. Accordingly, the user can easily grasp which area the selected photographing information to be displayed corresponds to as compared to the case where, for example, a line or a character is displayed as the peripheral portion specifying information.

  In addition, the mobile peripheral display device 1 sets the intermittent time and the display time so that the intermittent time and the display time are lower than the conscious perception limit value and are included in the range of unconscious perception. Then, the peripheral part specifying information is displayed for the set display time for each set intermittent time.

  Accordingly, the moving object peripheral display device 1 can potentially inform the user who visually recognizes the region to which the selected photographing information to be displayed corresponds.

  In particular, in the present embodiment, when the data generating unit 4 outputs the same peripheral unit specifying information to the display control unit 5, the mobile peripheral display device 1 sets the display time by the above-described processing. Then, the intermittent time is set to be longer according to the time from when the peripheral portion specifying information is first displayed to the present time. Thereby, it is possible to potentially inform the user of the time from when the peripheral portion specifying information is first displayed until the present time.

  Thereby, the user can grasp the time from when the peripheral part specifying information is first displayed until the present time. For example, the importance of the selected photographing information to be displayed (the peripheral part specifying information is displayed first). The longer the time from the start to the present time, the greater the importance of the selected photographing information).

  Moreover, the mobile body periphery display apparatus 1 specifies the area | region which can be visually recognized by the passenger | crew of the vehicle 100 based on vehicle information, and displays the selection imaging | photography information corresponding to the specified area | region. Thereby, the user can visually recognize the selected photographing information necessary for the user.

  In addition, the moving body peripheral display device 1 displays the peripheral portion specifying information within the range of the unconscious perception that is lower than the conscious perception limit value and corresponds to the contents of the vehicle information. Specifically, the mobile peripheral display device 1 sets the intermittent time and the display time in correspondence with the operation interval of the direction indicator when the vehicle information includes information on the direction indicator. And peripheral part specific information is displayed for the set display time for every set intermittent time.

  As a result, the user can grasp the content of the peripheral portion specifying information in accordance with the state of the vehicle 100 (in the case of the above-described specific example, the operation interval (for example, operation sound) of the direction indicator). As compared with the case where the mobile body peripheral display device 1 displays the peripheral part specifying information without corresponding to the contents of the vehicle information, the content of the peripheral part specifying information can be easily grasped.

  Next, a first modification of the mobile object peripheral display device 1 will be described. In the first modification, the data generation unit 4 generates peripheral part specifying information including the planar image information 40 and the symbol information 43 illustrated in FIGS. 8 to 9. Here, FIGS. 8 to 9 are explanatory diagrams showing an example of the planar image information 40 and the symbol information 43 to be displayed.

  The symbol information 43 is a triangle, and is generated so as to correspond to the selected shooting information acquired by the shooting information selection unit 3. In the present embodiment, the symbol information 43 is a triangle, but may be another figure, for example, a quadrangle. The symbol information 43 is preferably a simple graphic so that the user can easily recognize it.

  Specifically, for example, when the selected shooting information acquired by the shooting information selection unit 3 is the peripheral shooting information acquired by the shooting element 13 illustrated in FIG. Plane image information 40 and symbol information 43 are generated. As shown in FIG. 8, in this case, the region image information 41 indicates a region imaged by the imaging element 13, that is, a left rear region of the vehicle 100. The symbol information 43 has a shape corresponding to the left region (the angle A having the smallest angle among the corners A to C included in the symbol information 43 indicates the left region).

  Further, when the selected shooting information acquired by the shooting information selection unit 3 is the peripheral shooting information acquired by the shooting element 14 shown in FIG. 2, the plane image information 40 and the symbol information 43 shown in FIG. 9 are generated. . As shown in FIG. 9, in this case, the area image information 41 indicates an area captured by the imaging element 14, that is, an area on the right rear side of the vehicle 100. The symbol information 43 has a shape corresponding to the right region.

  In addition, the data generation unit 4 outputs both the plane image information 40 and the symbol information 43 to the display control unit 5 a predetermined number of times, and then outputs only the symbol information 43 to the display control unit 5. Therefore, the display control unit 5 displays both the plane image information 40 and the symbol information 43 on the in-vehicle display device 6 a predetermined number of times, and then displays only the symbol information on the in-vehicle display device 6.

  As described above, in the first modified example, the mobile object peripheral display device 1 displays both the planar image information 40 and the symbol information 43, and thus in which area of the area around the vehicle 100 the selected shooting information to be displayed is displayed. Compared with the case where only the planar image information 40 is displayed, the user can be more surely notified of the correspondence.

  In addition, the mobile object peripheral display device 1 displays only the symbol information 43 after displaying both the planar image information 40 and the symbol information 43 a predetermined number of times. Thus, only the symbol information 43 can be displayed after the user grasps the correspondence between the planar image information 40 and the symbol information 43, so the user can determine which region the selected photographing information displayed corresponds to. The display of the peripheral part specifying information can be simplified. In addition, since it is possible to inform the user of which area the selected photographing information to be displayed corresponds to only by using the symbol information 43, compared to the case where both the planar image information 40 and the symbol information 43 are displayed. Thus, it is possible to promptly notify the user which region the selected photographing information displayed corresponds to.

  Of course, the predetermined number of times can be changed according to the driving duration of the vehicle 100, the usage frequency of the mobile object periphery display device 1, the usage duration, the total usage time, and the like. Here, the driving continuation time is the time from the start of driving of the vehicle 100 to the present, and the usage continuation time is, for example, the time from the start of use of the mobile object peripheral display device 1 to the present. The total use time is, for example, the total time during which the mobile object peripheral display device 1 is used.

  In this case, the mobile peripheral display device 1 performs the following processing.

  In other words, the vehicle information output device 2 may include, for example, the operation continuation time of the vehicle 100 (this time is the use frequency, use continuation time, total use time, etc. of the mobile object peripheral display device 1) May be stored, and a predetermined number of times is set based on the stored operation continuation time. For example, the predetermined number of times is set to a smaller value as the operation duration time is longer. Then, a predetermined number of times information regarding the set predetermined number of times is generated and output to the data generation unit 4.

  The data generation unit 4 performs the following processing in addition to the processing described above. That is, the predetermined number of times set by the vehicle information output device 22 is recognized based on the predetermined number of times information given from the vehicle information output device 2.

  The planar image information 40 and the symbol information 43 described above are output to the display control unit 5 a predetermined number of times, and then only the symbol information 43 is output to the display control unit 5. Therefore, the display control unit 5 displays both the planar image information 40 and the symbol information 43 on the in-vehicle display device 6 a predetermined number of times, and then displays only the symbol information on the in-vehicle display device 6.

  As described above, when the predetermined number of times is changed according to the driving duration time of the vehicle 100, the usage frequency of the mobile object peripheral display device 1, the usage duration time, and the total usage time, the following effects are obtained. Can do.

  That is, the mobile object peripheral display device 1 determines the predetermined number of times according to the driving duration time of the vehicle 100, the usage frequency of the mobile object peripheral display device 1, the usage duration time, the total usage time, etc., that is, the driver's familiarity. Can be changed.

  For example, the mobile object peripheral display device 1 has the plane image information 40 and the symbol information 43 in the first one (for example, one hour after starting operation) with respect to continuous use (for example, one day operation) of the mobile object peripheral display device 1. Can be displayed together, and the number of times can be changed (for example, gradually decreased) according to the operation duration, etc., and only the symbol information 43 can be displayed finally (for example, after the evening). Thereby, the display of the peripheral part specifying information can be simplified according to the driver's familiarity.

  Next, a second modification of the mobile object peripheral display device 1 will be described. In the second modified example, as shown in FIGS. 10 to 11, the imaging elements 11 to 15 capture a wide-angle area including the area indicated by the selected imaging information 300 and wide-angle imaging that indicates the situation of the wide-angle area. Information 400 is acquired. Then, the shooting information selection unit 3 acquires a part of the wide-angle shooting information 400 as the selected shooting information 300.

  Further, the data generation unit 4 acquires wide-angle shooting information 400 including the selected shooting information 300 from the imaging elements 11 to 15, and outputs the acquired wide-angle shooting information 400 to the display control unit 5 as peripheral part specifying information. .

  Therefore, the display control unit 5 displays the selected shooting information 300 on the in-vehicle display device 6 and displays the wide-angle shooting information 400 on the display time in-vehicle display device 6 every intermittent time.

  As described above, in the second modification, the moving object peripheral display device 1 displays the wide-angle shooting information 400 indicating the situation in a wider range than the selected shooting information 300 as the peripheral portion specifying information. Therefore, it is possible to inform the user of which area the selected photographing information 300 to be displayed corresponds to, and to reduce the trouble of generating the peripheral portion specifying information.

  Further, since the mobile object peripheral display device 1 acquires a part of the wide-angle shooting information 400 acquired by the imaging elements 11 to 15 as the selected shooting information 300, the selected shooting information 300 and the wide-angle shooting information 400 are surely obtained. It can be displayed in correspondence. In addition, the number of imaging elements 11 to 15 can be reduced.

  Next, a third modification of the mobile object peripheral display device 1 will be described. In the third modification, the in-vehicle display devices 6 are installed on both the left and right sides of the vehicle interior. The data generation unit 4 also includes simplified peripheral portion specifying information (for example, the portion of the planar image information 40 illustrated in FIGS. 3 to 6 that does not include the region image information 41 (in the case of FIG. 3, the planar image information 40) (peripheral part specifying information) including the right side half) is omitted and output to the display control unit 5.

  When the shooting information selection unit 3 acquires the peripheral shooting information acquired by the shooting element 11 or the shooting element 13 as the selected shooting information, the display control unit 5 displays the selected shooting information on the left in-vehicle display device 6. In addition, the simplified peripheral portion specifying information is displayed on the display device 6 in the display time for every intermittent time.

  On the other hand, when the shooting information selection unit 3 acquires the peripheral shooting information acquired by the shooting element 12 or the shooting element 14 as the selected shooting information, the selected shooting information is displayed on the in-vehicle display device 6 on the right side, and The simplified peripheral portion specifying information is displayed on the display time in-vehicle display device 6 every intermittent time.

  As described above, in the third modified example, the mobile object peripheral display device 1 simplifies the peripheral part specifying information, and thus it is possible to reduce the trouble of generating the peripheral part specifying information. In addition, since the selected shooting information is displayed on the in-vehicle display device 6 corresponding to the selected shooting information, the selected shooting information 300 to be displayed can be selected from among the areas around the vehicle 100 even if it is simplified peripheral portion specifying information. It can potentially tell the user what to do with the area.

  In the present embodiment (including the first to third modifications), the mobile object peripheral display device 1 is applied to the vehicle 100. However, other mobile objects such as aircraft, railways, ships, and the like are used. Of course, the present invention can also be applied.

  Further, the vehicle information output device 2 may detect a user's fatigue level and workload (for example, a steering operation amount, a pedal operation amount, an in-vehicle device operation amount, etc.) and include the detection result in the vehicle information. Good.

  In this case, the imaging information selection unit 3 can acquire the selected imaging information based on the fatigue level of the user and the workload, in addition to the vehicle state. Moreover, the data generation part 4 can produce | generate peripheral part specific information based on a user's fatigue degree and work load other than the state of a vehicle. Moreover, the display control part 5 can set intermittent time and display time based on a user's fatigue degree and workload, besides the state of a vehicle.

  Thereby, the mobile body periphery display apparatus 1 can display selection imaging | photography information based on a user's fatigue degree and workload, other than the state of a vehicle. Further, it is possible to potentially inform the user which region the selected photographing information 300 to be displayed corresponds to based on the degree of fatigue and workload of the user in addition to the state of the vehicle. For example, as the fatigue level of the user increases, the intermittent time can be shortened and the peripheral portion specifying information can be displayed. In this case, the content of the peripheral part specifying information can be reliably transmitted to the user as compared with the case where the peripheral part specifying information is displayed based only on the state of the vehicle.

  Also, the peripheral part specifying information shown in FIGS. 3 to 6, FIG. 8 to FIG. 9 and FIG. 11 is an example, and it is needless to say that the peripheral part specifying information can take other forms.
