CPC H04N 23/61 (2023.01) [B60R 11/04 (2013.01); H04N 5/77 (2013.01)] | 5 Claims |
1. A dashboard camera device comprising:
a camera configured to image rearward from a self-vehicle and to detect illumination and blinking of a headlight of a following vehicle traveling behind the self-vehicle;
a recorder configured to record a video image captured by the camera;
an acceleration sensor configured to detect a vehicle vertical direction acceleration of the self-vehicle; and
a processor coupled to a memory, the processor configured to:
set a headlight-flashing threshold value based on a travel environment of the self-vehicle, the headlight-flashing threshold value being a threshold value for a change amount of a light intensity caused by blinking of the headlight of the following vehicle as detected by the camera,
in a case in which the vehicle vertical direction acceleration exceeds a predetermined threshold value, determine that the self-vehicle is traveling along an uneven road, and set the headlight-flashing threshold value to a higher threshold value as compared to the threshold value when the vehicle vertical direction acceleration does not exceed the predetermined threshold value, and
in a case in which the change amount of the light intensity, due to blinking of the headlight of the following vehicle, has exceeded the headlight-flashing threshold value plural times, cause the camera to record the video image.
