Abstract

A vehicular recording control device includes: an imaging data acquiring unit configured to acquire first imaging data from a first camera imaging surroundings of a host vehicle and second imaging data from a second camera imaging a cabin of the vehicle; a sightline determining unit configured to determine the direction of a sightline of an occupant of the vehicle from the second imaging data; a voice recognizing unit configured to recognize a voice command for instructing event recording; an output control unit configured to output information indicating the voice command to the occupant when the sightline determining unit determines that the sightline of the occupant is directed to a display unit; and a recording control unit configured to store the first imaging data as event data when the voice recognizing unit recognizes the voice command.

Claims (18)

1 . A vehicular recording control device comprising:

a processor coupled to a memory storing instructions for the processor to execute:

acquiring first imaging data from a first camera imaging surroundings of a vehicle and second imaging data from a second camera imaging a cabin of the vehicle;

determining a direction of a sightline of an occupant of the vehicle from the second imaging data;

recognizing a voice command for instructing event recording and a voice other than the voice command;

outputting information indicating the voice command to the occupant when the determining of the direction of the sightline determines that the sightline of the occupant is directed to a display unit and the recognizing the voice includes recognizing a voice based on speech other than the voice command in a period in which the sightline of the occupant is directed to the display unit or in a predetermined period after the sightline of the occupant has been directed to the display unit; and

a storage configured to store the first imaging data as event data when the recognizing of the voice command recognizes the voice command.

2 . The vehicular recording control device according to claim 1 , wherein the outputting information includes indicating the voice command to the occupant when determining the direction determines that the sightline of the occupant is directed to the display unit for a predetermined time or longer.

3 . The vehicular recording control device according to claim 1 , wherein the outputting information includes indicating the voice command to the occupant when the determining of the direction of the sightline determines that the sightline of the occupant is continuously directed to the display unit a plurality of times.

4 . The vehicular recording control device according to claim 1 , wherein the outputting information includes indicating the voice command to the occupant when the determining of the direction of the sightline determines that the sightline of the occupant is directed to the display unit and the recognizing of the voice command recognizes a voice partially matching the voice command or a synonym with the voice command as speech other than the voice command.

5 . The vehicular recording control device according to claim 1 , wherein the outputting information includes indicating a same voice as the voice command to the occupant from a speaker such that the voice is easy for the occupant to understand and is not input to a microphone acquiring the voice command.

6 . The vehicular recording control device according to claim 5 , wherein the outputting information includes outputting the same voice as the voice command to the occupant from a speaker that is provided above a seat on which the occupant sits or a neck speaker that is worn by the occupant.

7 . A recording method that is performed by a vehicular recording control device, the recording method comprising:

acquiring first imaging data from a first camera imaging surroundings of a vehicle and second imaging data from a second camera imaging a cabin of the vehicle;

determining a direction of a sightline of an occupant of the vehicle from the second imaging data;

recognizing a voice command for instructing event recording and a voice other than the voice command;

outputting information indicating the voice command to the occupant when it is determined that the sightline of the occupant is directed to a display unit and the recognizing the voice command includes recognizing a voice based on speech other than the voice command in a period in which the sightline of the occupant is directed to the display unit or in a predetermined period after the sightline of the occupant has been directed to the display unit; and

storing the first imaging data as event data when the voice command is recognized.
