Abstract
An image pickup device includes a first emission unit that emits a near infrared light toward a face of a driver from a front lower side of the driver, and a second emission unit that emits a near infrared light from an upper side of the driver. When a sunvisor is present at a storage position in which sunlight is not shielded, the second emission unit is disposed at a position to be covered with the sunvisor. A portion where the sunvisor present at a storage position covers the second emission unit is made of a material that shields a visible light contained in the sunlight and transmits the near infrared light.
Claims5
An image pickup device that is mounted on a vehicle and captures an image of a driver of the vehicle, comprising:
- a face image pickup unit arranged in front of a driver seat of the vehicle, and capturing an image of a face of the driver from a front side of the driver;
- a first emission unit arranged in front of the driver seat of the vehicle, and emitting a near infrared light toward the face from a front lower side of the driver;
- a sunvisor fitted to an upper side of the driver seat in a vehicle interior, and being movable between a light shielding position at which sunlight to the face is shielded and a storage position at which the sunlight to the face is not shielded;
- and
- a second emission unit located at a position to be covered with the sunvisor when the sunvisor is present at the storage position, and not to be covered with the sunvisor when the sunvisor is present at the light shielding position, and emitting a near infrared light toward the face of the driver, wherein
- a portion of the sunvisor which covers the second emission unit when the sunvisor is located at the storage position is made of a material that shields a visible light contained in the sunlight and transmits the near infrared light.
A near infrared light emission device that is mounted on a vehicle and emits a near infrared light toward a face of a driver of the vehicle, comprising:
- a first emission unit arranged in front of the driver seat of the vehicle, and emitting a near infrared light toward the face from a front lower side of the driver;
- a sunvisor fitted to an upper side of the driver seat in a vehicle interior, and being movable between a light shielding position at which sunlight to the face is shielded and a storage position at which the sunlight to the face is not shielded;
- and
- a second emission unit located at a position to be covered with the sunvisor when the sunvisor is present at the storage position, and not to be covered with the sunvisor when the sunvisor is present at the light shielding position, and emitting the near infrared light toward the face of the driver, wherein
- a portion of the sunvisor which covers the second emission unit when the sunvisor is located at the storage position is made of a material that shields a visible light contained in the sunlight and transmits the near infrared light.
A sunvisor that is fitted to a vehicle interior of a vehicle and shields sunlight to a face of a driver of the vehicle, comprising:
- a main body part made of a material that shields the sunlight;
- and
- an attaching part attaching the main body part to the vehicle interior in a state to be movable between a light shielding position at which the sunlight to the face is shielded and a storage position at which the sunlight to the face is not shielded, wherein
- the main body part is provided with a transmission window made of a material that shields a visible light contained in the sunlight and transmits the near infrared light.
