via an in-cabin camera configured to image an interior of a vehicle cabin of the vehicle, detecting a seated occupant seated in the plurality of vehicle seats;

determining the vehicle seat adjustment amount in accordance with the plurality of vehicle seats in which the detected occupant is seated; and

in a case in which the occupant selects the front windshield as the video display area and the processor detects occupants seated in the front seat and the rear seat, causing the front seat to move to a vehicle width direction edge and rotate from a vehicle forward direction to face toward a vehicle width direction inner side in a plan view so as to face a center portion of the front windshield, and causing the rear seat to move toward a vehicle width direction center.

6. The seat control method of claim 5 , further comprising:

determining a setting condition for the position and posture of each vehicle seat of the plurality of vehicle seats based on the selected video display area;

detecting the position and posture of each of the vehicle seats of the plurality of vehicle seats; and

determining a difference between the setting condition and the detected position and posture of the respective vehicle seats as the adjustment amount for each of the vehicle seats of the plurality of vehicle seats.

7. The seat control method of claim 5 , further comprising:

determining the adjustment amount for the plurality of vehicle seats along a vehicle front-rear direction and a reclining angle of a seatback section of the plurality of vehicle seats.

8. The seat control method of claim 5 , further comprising:

via the in-cabin camera, detecting an eye point of the occupant seated in the plurality of vehicle seats; and

determining the vehicle seat adjustment amount in accordance with the eye point of the occupant.

9. A non-transitory storage medium storing a seat control program executable by a processor to perform seat control processing, the seat control processing comprising:

based on a selection by an occupant of a vehicle, selecting a video display area for displaying a video from among a plurality of video display areas, including a front windshield provided at the vehicle;

determining an adjustment amount corresponding to the selected video display area for a plurality of vehicle seats, including a front seat and a rear seat provided in the vehicle;

modulating a position and posture of the plurality of vehicle seats based on the determined vehicle seat adjustment amount;

determining the adjustment amount for the position of the plurality of vehicle seats along a vehicle width direction, and a rotation angle of the plurality of vehicle seats about an axis along a vertical direction;

via an in-cabin camera configured to image an interior of a vehicle cabin of the vehicle, detecting a seated occupant seated in the plurality of vehicle seats;

determining the vehicle seat adjustment amount in accordance with the plurality of vehicle seats in which the detected occupant is seated; and

in a case in which the occupant selects the front windshield as the video display area and the processor detects occupants seated in the front seat and the rear seat, causing the front seat to move to a vehicle width direction edge and rotate from a vehicle forward direction to face toward a vehicle width direction inner side in a plan view so as to face a center portion of the front windshield, and causing the rear seat to move toward a vehicle width direction center.
