1. A driver monitoring device comprising:
a processor; and
a memory storing instructions that, when executed by the processor, cause the driver monitoring device to perform operations, the operations comprising:
detecting an unbalanced posture of a driver based on an image of a driver's seat of a vehicle captured by a camera;
determining whether the unbalanced posture of the driver is a habitual unbalanced posture of the driver;
calculating an opening degree of at least one eye of the driver based on the image in a case in which it is determined that the unbalanced posture is other than the habitual unbalanced posture of the driver;
determining whether it is a timing to give a notification to the driver in a case in which the vehicle is traveling and the opening degree is equal to or larger than a first threshold; and
giving the notification to the driver in a case in which it is determined that it is the timing to give the notification.
