  • step S104 If it is determined in step S104 that the motion is not a reciprocating motion (step S104: No), the switching control unit 108 controls the display control unit 105 to shift the display range in the direction of the detected motion (step S104). S206).
  • the display control unit 105 can take the following two types of shift processing.
  • As the first shift process only the video of the rear camera 51 displayed in the central display section 60C is shifted, and the left camera 52 and the right camera 53 displayed in the left display section 60L and the right display section 60R. This video is a process that does not shift.
  • the images displayed in the left display section 60L and the right display section 60R do not need to be shifted because they correspond to the rear images viewed by the door mirror, and are displayed in the center display section 60C. Since the video corresponds to the video seen by the room mirror, it is shifted as necessary.
  • the user can intuitively perform the switching between the mirror mode and the display mode and the operation of the display range of the display target necessary in the display mode without impairing the safety.
  • the second shift process in addition to the video of the rear camera 51 displayed in the center display section 60C, the left camera 52 and the right camera displayed in the left display section 60L and the right display section 60R. Similarly, the 53 images are shifted.
  • the same display shift can be performed even when the room mirror 2 with a display function cannot change the orientation mechanically. By such processing, the user can intuitively perform the switching between the mirror mode and the display mode and the operation of the display range of the display target in the display mode without impairing the safety.
  • FIGS. 12A to 12E are diagrams conceptually showing examples of shifting the display range in the process of step S206.
  • 12A to 12E show an example of the second shift process.
  • the display range 501 in the shooting range 500 of the rear camera 51 is the display data of the rear panel 51 taken by the rear camera 51 by the display control unit 105 as the display data of the display panel 35. It is a range.
  • the display range 511 in the shooting range 510 of the left-side camera 52 is the display range of the left-side camera 52 shot by the left-side camera 52 by the display control unit 105.
  • the display range 521 in the shooting range 520 of the right-side camera 53 is cut by the display control unit 105 from the shooting range 520 of the right-side camera 53 shot by the right-side camera 53. This is the range of display data.
  • the display control unit 105 When the display control unit 105 performs the shift process in each direction, the display range 501 in the shooting range 500 of the rear camera 51, the display range 511 in the shooting range 510 of the left camera 52, and the shooting range 520 of the right camera 53 are displayed.
  • the display range 521 is combined and displayed on the liquid crystal panel 31.
  • the display range 501 in the shooting range 500 of the rear camera 51 displayed in the shift process of step S106 may be changed as compared with the display range before the shift.
  • the display range 501 in the shooting range 500 of the rear camera 51 after the shift is narrower than that before the shift, the same effect as the zoom of the display range can be obtained. For this reason, it is possible to visually check the range in which the instruction to move the display range is given by motion detection.
  • the display range 501 in the shooting range 500 of the rear camera 51 after the shift is made wider than that before the shift, the display range can be widened.
  • These processes may be set in advance, or may be determined by the time length of the peak waveform indicating the motion detected in step S101. Specifically, if the peak waveform indicating the motion detected in step S101 is less than 0.4 seconds as an example of the threshold value, the display range 501 in the shooting range 500 of the rear camera 51 after the shift is narrower than before the shift, If the time length is equal to or greater than the threshold and the upper limit is recognized as a motion, the display range 501 in the shooting range 500 of the rear camera 51 after the shift is made wider than before the shift.
  • the display in the imaging range 510 of the left camera 52 corresponding to the motion detection direction Either the range 511 or the display range 521 in the shooting range 520 of the right side camera 53 is cut out narrowly, and if it is equal to or larger than the threshold, it is cut out widely.
  • the mirror device with a display function and the display switching method according to the present invention are useful when displaying an image of a camera that captures the rear of the vehicle, etc., on a rearview mirror attached to the interior of the vehicle. Suitable for switching functions and operating the display range.
