WE CLAIM:
1. An irradiation apparatus comprising:
one or more irradiation units for displaying information outside a vehicle by emitting light;
an information acquisition unit for acquiring information regarding a situation inside and outside the vehicle;
a determination unit for determining whether or not the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit meets a display start condition; and
a control unit for displaying, outside the vehicle, the information corresponding to the display start condition determined by the determination unit to meet the information regarding the situation inside and outside the vehicle by controlling the one or more irradiation units, wherein
the determination unit determines whether or not the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit meets a display change condition after display of the information outside the vehicle, and
the control unit changes a display mode of the information displayed outside the vehicle by controlling the one or more irradiation units when the determination unit determines that the information regarding the situation inside and outside the vehicle meets the display change condition.
2. The irradiation apparatus according to claim 1, wherein
the control unit displays an animation in which an irradiation state of a light pattern including a single or a plurality of light elements continuously changes outside
83

the vehicle by controlling the one or more irradiation units.
3. The irradiation apparatus according to claim 1, wherein
the control unit displays an image outside the vehicle by controlling the one or more irradiation units.
4. The irradiation apparatus according to claim 2, wherein
the control unit changes at least one of a color, brightness, an irradiation position, and an irradiation state change speed of the light pattern in the animation by controlling the one or more irradiation units.
5. The irradiation apparatus according to claim 3, wherein
the control unit changes at least one of a shape, a color, brightness, a size, a display position, display timing, and display time of the image displayed outside the vehicle by controlling the one or more irradiation units.
6. The irradiation apparatus according to claim 1, wherein
the determination unit determines whether or not at least one of a position of a moving object around the vehicle, a moving direction thereof, a distance between the vehicle and the moving object, and a moving speed meets a display change condition, and
when it is determined that at least one of the position of the moving object, the moving direction thereof, the distance between the vehicle and the moving object, and the moving speed meets the display change condition, the control unit changes a display mode of one or more pieces of information by controlling the one or more irradiation
84

units.
7. The irradiation apparatus according to any one of claims 1 to 6, wherein
the determination unit determines whether or not the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit meets a display return condition after change of the display mode of the information displayed outside the vehicle, and
when the determination unit determines that the information regarding the situation inside and outside the vehicle meets the display return condition, the control unit returns the information displayed outside the vehicle to the display mode before the change by controlling the one or more irradiation units.
8. The irradiation apparatus according to claim 1, wherein
the control unit causes an in-vehicle notification unit to notify a person in the vehicle that information is being displayed outside the vehicle.
9. The irradiation apparatus according to claim 8, wherein
the in-vehicle notification unit is an in-vehicle lamp or an in-vehicle monitor for emitting light in the vehicle.
10. The irradiation apparatus according to claim 8 or 9, wherein
the control unit causes the in-vehicle notification unit to continue the notification to a person in the vehicle until a certain time has elapsed after end of display of information outside the vehicle.
85

11. The irradiation apparatus according to claim 2, wherein
when both an out-of-vehicle lamp for emitting light outside the vehicle and a light pattern of the animation are blinked, a lighting timing of the light pattern of the animation matches a lighting timing of the out-of-vehicle lamp.
12. The irradiation apparatus according to claim 11, wherein
when the lighting timing of the animation is earlier than the lighting timing of the out-of-vehicle lamp, the control unit matches the lighting timing of the light pattern of the animation with the lighting timing of the out-of-vehicle lamp by extending lighting time of the light pattern of the animation.
13. The irradiation apparatus according to claim 11, wherein
when the lighting timing of the animation is later than the lighting timing of the out-of-vehicle lamp, the control unit matches the lighting timing of the light pattern of the animation with the lighting timing of the out-of-vehicle lamp by shortening extinction time of the light pattern of the animation.
14. The irradiation apparatus according to claim 2, wherein
when both an out-of-vehicle lamp for emitting light outside the vehicle and a light pattern of the animation are blinked, the light pattern of the animation and the out-of-vehicle lamp are alternately lit.
15. An irradiation method comprising:
a step in which an information acquisition unit acquires information regarding a situation inside and outside a vehicle;
86

a step in which a determination unit determines whether or not the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit meets a display start condition; and
a step in which a control unit displays, outside the vehicle, the information corresponding to the display start condition determined by the determination unit to meet the information regarding the situation inside and outside the vehicle by controlling one or more irradiation units for displaying information outside the vehicle by light irradiation, wherein
the determination unit determines whether or not the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit meets a display change condition after display of the information outside the vehicle, and
the control unit changes a display mode of the information displayed outside the vehicle by controlling the one or more irradiation units when the determination unit determines that the information regarding the situation inside and outside the vehicle meets the display change condition.
