Is displayed on the display means 4a and 4b, and video information of the storage unit 13a corresponding to the car height position is displayed on the display means 4a and 4b at night and in stormy weather.

  The day / night determination unit 12a applies the astronomical day / night definition as it is, and uses, for example, current date / time information, data on the forecasted sunrise time of the day at the building location, and forecasted sunset time of the day. To judge day and night. That is, when the current date and time information is a time between the predicted sunrise time of the day at the building location and the predicted sunset time of the day, it is determined to be noon, and otherwise it is determined to be night. The sunrise and sunset forecast times for each point in Japan are announced on the website by the Japan Coast Guard's Marine Information Department. By specifying the year and month and specifying the location by latitude / longitude or major city name, the daily forecast time of the month can be obtained. Since the sunrise and sunset times of the same month and day at the same point are almost the same every year, even if a simple comparison table of the month and day of the year and the sunrise and sunset times is stored and used every year, the error is kept within a few minutes. It can also be used for day and night judgment.

  The weather determination unit 12b described above determines the current weather by any of the following processes. That is, the average luminance value of the output video of the camera 9 can be measured. If the average luminance value is larger than a preset threshold value, it is determined that the weather is sunny, and otherwise, the weather is stormy. to decide. Also, if the current weather performance information near the building location, which is reported by electronic data from a predetermined organization, such as the Japan Meteorological Agency, or a weather service company, is sunny, the weather is judged to be sunny, and other forecasts Judge that the weather is stormy weather. In addition, if the weather forecast information in the near future near the building location reported by the Japan Meteorological Agency or weather service company using electronic data is clear, the weather is judged to be clear, otherwise the weather is Is judged to be stormy weather.

  In the first embodiment, the cameras 9a and 9b are moved up and down in advance during a fine daytime so that the camera 9a captures the east landscape and the camera 9b captures the west landscape. The data is stored in the storage unit 13a of the image processing unit 13. In addition, although it is the time zone of imaging by the cameras 9a and 9b, the camera 9a takes the afternoon as the imaging time zone and images the landscape on the east side. On the other hand, the camera 9b images the west landscape in the morning as the imaging time zone.
