Abstract: A state detection device (100) detects a state of a driver driving an automobile (300), and includes: a first camera (110) that captures a face of the driver at a first frame rate; a. second camera. (120) that captures an environment in a forward direction of the automobile at a second frame rate;
and a. processor (130) that processes images obtained from the first and second cameras (110, 120). The processor (130) calculates a :line-of-sight direction of both. eyes of the driver based on a face image obtained from. the first camera (110) and calculates a focal position of the driver based on the hue-of-sight direction. of both. eyes of the driver, and detects the state of the driver by determining the state of the driver based on the focal position and a forward image obtained from the second camera (120). The first frame rate is N times the second frame rate (N is an integer of 1 or greater),
