Description

  In the present invention, when monitoring images acquired from a plurality of monitoring locations in a vehicle are displayed on the same display screen, it is not dependent on the image content which monitoring location is being displayed. The present invention relates to a display method of a monitoring image of a vehicle that is displayed in a state where it can be immediately recognized.

  In recent years, the number of vehicles equipped with a back camera has increased. In such vehicles, when the back gear is engaged, the rear view of the vehicle is displayed on the monitor of the navigation system. Recently, there are cameras that are mounted not only on the rear view but also on the side and front of the car, and can also display monitoring images of these parts. In this case, these monitoring images are displayed on one monitor screen.

  However, there are the following problems when monitoring images acquired from a plurality of monitoring locations are displayed on the same display screen. For example, when displaying the left and right side surfaces in front of the car, the left and right side surfaces in the rear, and the entire rear field of view on one display screen, the currently displayed monitoring image belongs to any monitoring location. It may not be possible to know immediately.

  For this reason, the passenger is at a loss for a moment where he is looking. In particular, when someone else rents a car, it is confusing where the scene shown on the display screen is. Therefore, there is a problem that it is not possible to determine wrinkles based on the monitoring image.

  SUMMARY OF THE INVENTION An object of the present invention is to propose a method for displaying a monitoring image of a vehicle so that the displayed monitoring image can be recognized immediately without confirming the content of the monitoring image. There is.

  In order to solve the above-described problem, the present invention is a vehicle monitoring image display method for displaying monitoring images acquired from a plurality of monitoring locations in a vehicle on the same display screen. In this case, at least one of the following display forms 1 and 2 is adopted as the display form.

Display mode 1: A display frame having a different shape is assigned to each monitoring location, and a monitoring image is displayed in the corresponding display frame. Display mode 2: An image representing a vehicle part corresponding to the monitoring location is acquired from the monitoring location. Display form displayed on a part of the display screen together with the monitored image

  Here, in the display mode 1, it is preferable that at least one of a parallelogram, a trapezoid, and a fan shape associating the front and rear and the left and right of the vehicle is used as the display frame.

  The monitoring locations include a front view, a rear view, a right view, a left view, a front right view, a rear right view, a front left view, and a rear left view. In this case, it is desirable to employ a fan-shaped display frame reminiscent of a windshield or rear glass as a display frame for the monitoring image of the front visual field and the rear visual field. In addition, the display frames of the monitoring images of the right field of view, the front right field of view, the rear right field of view, the left side field of view, the front left field of view and the rear left field of view are mutually tilted so as to be reminiscent of the left and right and front and rear of the car. It is desirable to adopt a parallelogram or trapezoidal display frame arranged on the display screen so as to be different.

  Further, when a monitoring image of a desired monitoring location is selected and displayed from among a plurality of monitoring locations, display frames having different shapes according to the display mode 1 are simultaneously displayed on the display screen, and one display frame is displayed. When selected, it is desirable to enlarge the display frame and display a corresponding monitoring image in the display frame.

  In the vehicle monitoring image display method of the present invention, the monitoring images displayed on the same display screen are displayed in different display frames and / or displayed together with an image representing the monitoring part of the vehicle. Therefore, a passenger such as a driver can immediately know which part of the monitoring image is displayed from the difference in the display form without confirming the content of the displayed monitoring image.

  Further, in the present invention, since the vehicle windshield, rear glass, or fan-shaped, parallelogram-shaped, and trapezoidal display frames reminiscent of the left and right, front and rear of the vehicle are used, any part of the vehicle is intuitively viewed when viewing the display screen. This is convenient because it is possible to know whether the image is a monitoring image.
