  Then, by the operation of the operation units 50 to 52, the interlock of the operation of the left winker 6L and the operation of the right winker 6R and the priority display of the predetermined image of the monitor 3 is selected as interlock invalidated. Then, even if the left winker 6L is operated, the image obtained by the second camera 22 is not displayed on the monitor 3 in this example. Further, even if the right turn signal 6R is operated, the image obtained by obtaining the third camera 23 is not displayed on the monitor 3 in this example (see FIGS. 9A and 9B).

  Further, interlocking between the operation of the left winker 6L and the operation of the right winker 6R and the priority display of the predetermined image of the monitor 3 is selected to interlock only the left by the operation of the operation units 50 to 52. Then, even if the right blinker 6R is operated, the image obtained by acquiring the third camera 23 is not displayed on the monitor 3 in this example (see FIGS. 9A and 9B).

  Further, by the operation of the operation units 50 to 52, interlocking of the operation of the left winker 6L and the operation of the right winker 6R and the priority display of the predetermined image of the monitor 3 is selected to interlock only the right. Then, even if the left winker 6L is operated, the image obtained by the second camera 22 is not displayed on the monitor 3 in this example.

  In the case of selecting interlocking invalidity, interlocking only to the left and interlocking only to the right, at least one of the leftward video and the rightward video is not displayed on the monitor 3. However, the operation signal of the left winker 6L and the operation signal of the right winker 6R are recorded on the SD card 40 by the recorder 4. Alternatively, it is sent from the sending unit 60 to the server.

As a result, when the right winker 6R is operated, as shown in FIGS. 8A and 8B, the indoor video is displayed on the monitor 3 with priority over other video. For this reason, there is a gap between the awareness of the driver's right blinker 6R operation and the indoor video to be output with priority, and the driver is bothersome with the indoor video to be output with priority.

  Therefore, interlocking between the operation of the left turn signal 6L and the operation of the right turn signal 6R and the priority display of the predetermined image of the monitor 3 is selected to interlock only the left by the operation of the operation units 50-52. Then, as described above, even if the right turn signal 6R is operated, the image obtained by acquiring the third camera 23 In this example, the indoor image shown in FIGS. 8A and 8B is not displayed on the monitor 3 (FIG. 9A) , (B))). That is, instead of the indoor video shown in FIGS. 8A and 8B, the blank video shown in FIGS. 9A and 9B is displayed on the monitor 3. Note that instead of the blank image, an image may be displayed so as not to bother the driver.

  Reloading the third camera 23 mounted on the right side of the vehicle 2 is suitable for the left lane. Further, in the case of the right lane, the second camera 22 mounted on the left side of the vehicle 2 may be replaced. At this time, interlocking between the operation of the left turn signal 6L and the operation of the right turn signal 6R and the priority display of the predetermined image of the monitor 3 is selected to interlock only the right by the operation of the operation units 50-52. Then, as described above, even when the left winker 6L is operated, the image obtained by the second camera 22 is not displayed on the monitor 3.

  Hereinafter, the flow of the operation of the winker operation cancellation forgetting prevention function of the vehicular image display recording apparatus 1 according to this embodiment will be described with reference to the flow chart of FIG.

  First, the video display recording device 1 for vehicle is started (start). First, the CPU 72 determines whether the left winker 6L or the right winker 6R has been operated (step S1). If the left winker 6L or the right winker 6R is not operated, the process returns to step S1.

  If the left winker 6L or the right winker 6R is operated in step S1, the process proceeds to step S2. In this step S2, the CPU 72 determines whether or not the operation of the left winker 6L or the right winker 6R has been canceled (step S2). When the operation of the left winker 6L or the right winker 6R is released, the process proceeds to the end.

  If the operation of the left winker 6L or the right winker 6R is not canceled in step S2, the process proceeds to step S3. In step S3, the CPU 72 determines whether a predetermined time has elapsed (step S3). If the predetermined time has not elapsed, the process returns to step S3.

  If the predetermined time has elapsed in step S3, the process proceeds to step S4. In step S4, the CPU 72 causes the speaker 53 to output a beep sound. In addition to the output of the beep sound from the speaker 53, a logo or the like may be displayed on the monitor 3 indicating that the cancellation of the blinker operation has been forgotten.

  Then, the process proceeds from step S4 to step S5. In this step S5, the CPU 72 determines again whether or not the operation of the left winker 6L or the right winker 6R has been canceled (step S5). If the operation of the left winker 6L or the right winker 6R is not canceled, the process returns to step S4, and the process circulates through steps S4 and S5. Therefore, the beeper output from the speaker 53 continues.

  If the CPU 72 determines in step S5 that the operation of the left winker 6L or the right winker 6R has been canceled, the process proceeds to step S6. In step S6, the CPU 72 stops the output of the beep sound from the speaker 53 (step S6), and proceeds to the end. As a result, the operation of the winker operation cancellation forget prevention function stops.
