  The operation of the vehicle back monitor device 1 performed for parking at a desired position will be described with reference to FIGS.

  In order to display a mark for parking at a desired position on the display monitor 13 during parking, it is necessary to draw the mark and register it in the vehicle back monitor device 1 in advance. This registration operation will be described with reference to FIG. FIG. 2A is a diagram for explaining the position of the vehicle 22 when the user parks at a desired position in the parking lot 21 at home. Here, it is assumed that the user has parked the vehicle 22 backward. When the vehicle 22 is moved backward and parked, the rear of the vehicle cannot be seen well, so the wheels need to be turned over many times.

  FIG. 2B is a diagram showing an image behind the vehicle displayed on the display monitor 13 when the vehicle 22 is parked at a desired position. Here, it is assumed that a part of the parking lot 21 is displayed on the display monitor 13. On the display screen of the display monitor 13, a registration button 23 and a cancel button 24 are displayed together with a video behind the vehicle. The registration button 23 is a button for storing, that is, registering, a diagram drawn on the display screen in the data storage unit 16. The cancel button 24 is a button for deleting the drawn diagram.

  When the user parks at a desired position, the user searches for the target of the mark from the display screen of the display monitor 13 and draws the mark at the position where the target is displayed. Here, it is assumed that an edge 21a of the parking lot behind the vehicle is searched for as a mark for parking. A line 25 is drawn by tracing the edge 21a of the parking lot displayed on the display screen with a finger so as to serve as a parking mark. Then, the registration button 23 is pressed, and the drawn diagram 25 is registered in the data storage unit 16. Further, when the registration button 23 is pressed, the position coordinates of the vehicle 22 when the diagram 25 is drawn, which is simultaneously detected by the current position detection device 12, is stored in the data storage unit 16.

  A driving operation for parking at a desired position after registering the mark will be described with reference to FIG. It is assumed that the user is going to park in the parking lot 21 by retracting the vehicle 22 in the direction of the arrow as shown in FIG.

  When the shift lever is set to the “R” position (reverse vehicle position), an image of the rear of the vehicle is displayed on the display monitor 13 as shown in FIG. Then, the vehicle position data stored in the data storage unit 16 is collated from the position coordinates of the vehicle 22 detected by the current position detection device 12, and a diagram 25 input when the vehicle is parked in the parking lot 21 is a vehicle 25. It is displayed superimposed on the back image. Here, the position and size of the displayed diagram 25 with respect to the display screen are the same as when the drawing is performed.

  The user moves the vehicle 22 backward so that the edge 21a of the parking lot projected as a video behind the vehicle overlaps the line 25. And the vehicle 22 stops at the point where the edge 21a of the parking lot overlaps the line 25. By the driving operation as described above, the operator can easily and accurately park the vehicle 22 at a desired position.

  The mark display process of the vehicle back monitor device 1 according to the embodiment of the present invention will be described with reference to the flowchart of FIG. The process of FIG. 4 is executed in the control circuit 11 by a program that starts when the shift lever is set to the “R” position.

  In step S401, an image behind the vehicle is displayed on the display monitor 13. In step S <b> 402, the current location of the vehicle 22 is detected by the current location detection device 12. In step S403, it is determined whether or not the detected current location is within a predetermined range from the vehicle position coordinates stored in the data storage unit 16. If it is within the predetermined range, an affirmative determination is made in step S403, and the process proceeds to step S404. If it is not within the predetermined range, the mark display process is terminated.

  In step S404, a diagram 25 corresponding to the position coordinates of the vehicle whose detected current location is included in the predetermined range from the diagrams stored in the data storage unit 16, that is, within the predetermined range from the detected current location. The stored diagram 25 is read. In step S405, the diagram 25 is displayed superimposed on the image displayed on the display monitor 13 without changing the position and size with respect to the display screen when drawn. In step S406, the R position detection device 18 determines whether or not the position of the shift lever is the “R” position. If the position is “R”, the process returns to step S405. If the position is other than “R”, the determination in step S406 is negative, and the mark display process ends.

The vehicle back monitor device 1 according to the above embodiment has the following operational effects.
(1) It is possible to draw a diagram superimposed on the video behind the vehicle displayed on the display monitor 13. Therefore, a mark for parking at the desired position can be drawn on the display screen of the display monitor 13 when parked at the desired position. Moreover, since the attachment position of the video camera 17 which image | photographs the vehicle back is not specifically limited, the vehicle model which attaches the back monitor apparatus 1 for vehicles is not limited.

(2) Since the mark corresponding to the vehicle position is displayed when parking, only the mark related to the parking position is displayed. Therefore, an unnecessary mark is displayed on the vehicle back monitor device, and the mark does not become an obstacle. Even when a plurality of marks are registered, the marks corresponding to the respective parking positions are automatically displayed, so that the operator does not need to select the marks related to the respective parking positions. Therefore, the convenience for the operator is improved.

The navigation apparatus 1 of the above embodiment can be modified as follows.
(1) The input device is not limited to the touch panel 18 as long as a mark can be drawn on the display screen displaying the vehicle rear view video. You may enable it to input by operation of an operation panel or a remote control.

(2) The present invention is not limited to the R position detection device 18 as long as it can detect that the gear position of the vehicle is in the position of the back gear.

(3) If it is a vehicle monitor device that displays the vehicle periphery, it is not limited to a vehicle monitor device that displays the vehicle rear. For example, a vehicle monitoring device that displays the side direction of the vehicle or the front of the vehicle may be used. This is because the vehicle can be parked and stopped at a desired position by displaying a mark also in the side direction of the vehicle or in front of the vehicle.

(4) When registering a map to serve as a landmark, the locations such as “Home Parking”, “Company Parking”, “Contracted Parking”, and “Supermarket Parking” were also registered and registered. A place may be displayed as a list or icon, and a desired placemark may be displayed on the display screen by selecting a place where the placemark is to be displayed from the list or icon. The present invention can also be applied to a place where the current location cannot be detected or the same mark can be used even if the place changes, such as a parking lot in a supermarket, and the convenience for the user is improved.

(5) Trace the location of the mark and the display position in the rear image of the vehicle with your finger, etc., and if the display position of the specified location matches the mark, the mark will flash to indicate that it matches. A special display, buzzer sound, voice, etc. may be output. In addition, the entire image or a part of the image data at the time of registration is stored, and if it is determined that the image captured by image processing matches the image of the image data, the mark is determined to match. Then, it may be informed that they match. Since it is not necessary to always look at the display monitor 13, it is possible to park at a desired position while checking the surroundings.

(6) A user searches for a mark that is a mark from among those displayed on the display monitor 13 and draws and registers the mark. However, a mark that is automatically marked by performing image processing on the display screen of the display monitor 13 You may make it search and a mark is automatically drawn and registered. The user does not need to perform an operation for registering the mark, and convenience is improved.
