State monitoring device

A state monitoring device mounted in a vehicle, comprising:

• a light emitter that emits light to irradiate an area predetermined as an area where a vehicle driver face is positioned;
• an imaging unit that images an imaging area including the predetermined area;
• a state monitoring unit that monitors a state of the driver based on a result of image processing on an image generated by the imaging unit;
• a state determination unit that determines whether the driver is ready to drive the vehicle or unready to drive the vehicle;
• and
• a light emission control unit that
• (a) when the state determination unit determines that the driver is unready to drive the vehicle, executes specific processing to lower a light emitting function of the light emitter, and
• (b) when the state determination unit determines that the driver is ready to drive the vehicle, makes the light emitter emit the light without lowering the light emitting function of the light emitter.
