However, as an image that is required to be promptly displayed when parking, for example, as shown in FIG. An image of the monitoring area A4 immediately after the host vehicle 20, that is, an immediately monitoring image can be used. Moreover, it is also possible to add a video for monitoring immediately after the fifth video and the sixth video, and to make these video images that are required to be displayed promptly when starting and parking. In this case, the fifth video is displayed on the liquid crystal panel 2 based on the first push by the third switch 71, the sixth video is displayed on the liquid crystal panel 2 by the next switching operation, and further the next switching operation. After that, the video for monitoring is displayed on the liquid crystal panel 2.

  In the above example, the third switch 71 is newly provided for the second switch 7. However, the switches 7 and 71 are configured to be shared as the fourth switch (fourth SW) 72 as shown in FIG. It is also possible. In the vehicle display device 10 shown in FIG. 10, the push operation by the second switch 7 is a short push operation by the fourth switch 72, and the push operation by the third switch 71 is a long push operation by the fourth switch 72. By distinguishing these operations, the fourth switch 72 can be shared.

  The fourth switch 72 corresponds to the switch means described in the claims, the short pressing operation by the fourth switch 72 corresponds to the first pressing operation described in the claims, and the long pressing operation by the fourth switch 72 is This corresponds to the second pressing operation described in the claims.

  The short pressing operation refers to an operation of pressing the fourth switch 72 for a short pressing time (for example, 1 second or less), and the long pressing operation refers to pressing the fourth switch 72 for a pressing time longer than the pressing time of the short pressing operation. A pressing operation. Therefore, a plurality of videos (first video to sixth video) are switched and displayed in a predetermined switching order, and a plurality of videos (first video to sixth video) are displayed regardless of the predetermined switching order. It is possible to realize both the selection and display of a predetermined fifth video from the inside by one switching operation without adding a new switch means.
