## Abstract

A disinfection system disinfects an inside of a building or a moving body. The disinfection system includes an ultraviolet irradiator, a recognition sensor that recognizes a situation of the inside of the building or the moving body, and a control device configured to automatically control the ultraviolet irradiator based on the situation of the inside of the building or the moving body, which is recognized by the recognition sensor, to disinfect the inside of the building or the moving body.

## Claims

### Claim 1

A disinfection system that disinfects an inside of a building or a moving body, the disinfection system comprising:
an ultraviolet irradiator;
a recognition sensor that recognizes a situation of the inside of the building or the moving body; and
a control device configured to automatically control the ultraviolet irradiator based on the situation of the inside of the building or the moving body, which is recognized by the recognition sensor, to disinfect the inside of the building or the moving body.

### Claim 2 (depends on 1)

The disinfection system according to claim 1, wherein the control device is configured to, upon determining, based on a recognition result by the recognition sensor, that there is no person within an irradiation range of the ultraviolet irradiator, perform irradiation by the ultraviolet irradiator.

### Claim 3 (depends on 1)

The disinfection system according to claim 1, wherein the control device is configured to, upon determining, based on a recognition result by the recognition sensor, that there is no person within an irradiation range of the ultraviolet irradiator but there is a person who exists outside the irradiation range, perform irradiation by the ultraviolet irradiator after giving a warning to the person who exists outside the irradiation range.

### Claim 4 (depends on 1)

The disinfection system according to claim 1, wherein the control device is configured, upon determining, based on a recognition result by the recognition sensor, that there is a person within an irradiation range of the ultraviolet irradiator, not to perform irradiation by the ultraviolet irradiator.
