1. An in-cabin monitoring system, comprising:
a camera which captures images of an inside of a cabin of a vehicle;
a light source which irradiates the inside of the cabin with light; and
a controller which controls the camera and the light source,
wherein the light source is capable of emitting first light which is to be emitted when checking whether a person is present using the camera and second light which is light stronger than the first light,
before a user gets in the vehicle and after the user gets out of the vehicle, the controller captures a first image of the inside of the cabin using the camera while causing the light source to emit the second light,
when the controller receives a door unlock signal of the vehicle before the user gets in the vehicle, the controller checks whether no person is present in the inside of the cabin via emitting the first light, and then, after the controller checks whether no person is present in the inside of the cabin via emitting the first light, the controller captures a second image of the inside of the cabin using the camera via emitting the second light, and
when the controller receives a door lock signal of the vehicle after the user gets out of the vehicle, the controller checks whether no person is present in the inside of the cabin via emitting the first light, and then, after the controller checks whether no person is present in the inside of the cabin via emitting the first light, the controller captures a third image of the inside of the cabin using the camera via emitting the second light.
